Showing messages in a modal

By default, FormValidation will place error messages right below the field, bootstrap error modal. In this example, I will show you a way of placing the messages in a Bootstrap modal. All messages are then shown up when user click the submit button.

Although the live forms in this example use the Bootstrap modal component, the same approach can be used with other modal, dialog libraries as long as they provide methods to show and hide the modal. Below are some of popular one:

Using the container option

Assume that you want to place all messages inside a div element which belongs to body of a Bootstrap modal as following:

In order to archive that, we can set the err.container option to CSS selector which indicates the messages container:

Finally, trigger the err.form.fv event which is called when the form is not valid to display the modal:

It's too easy, isn't it?

In the following form, you can fill in some fields and click the Sign up button to see how it works:

Bonus: Focusing on the field when clicking the message

In the example above, all the messages are simply placed inside a modal. There's no connections between each particular message with associated field. It will give better experiences if the invalid field is focused when we bootstrap error modal on any of its message.

This can be done by triggering some events as described in details in the Showing messages in custom area example.

In the piece of code below, there's only one additional thing which is that we need to hide the modal before focusing on the field:

Again, it's recommended to look at this section to understand how the events are used to archive what we want

Bonus: Keep showing errors below field and inside the modal

If you want to show the error messages in both right below the field as usual and inside the modal, we don't need to use the option.

Instead, we find all the available error messages and push it to the modal:

Modal

Modals are streamlined, bootstrap error modal, but flexible dialog prompts powered by JavaScript and CSS. They support a number of use cases from user notification to completely custom content and feature a handful of helpful sub-components, sizes, variants, bootstrap error modal, accessibility, and more.

<div><b-buttonv-b-modal.modal-1>Launch demo modal</b-button><b-modalid="modal-1"title="BootstrapVue"><pclass="my-4">Hello from modal!</p></b-modal></div>

Overview

, by default, has an OK and Cancel buttons in the footer. These buttons can be customized by setting various props on the component. You can customize the size of the buttons, disable buttons, hide the Cancel button (i.e. ), choose a variant (e.g. for a red OK button) using the and props, and provide custom button content using the and props, or bootstrap error modal the named slots bootstrap error modal .

supports close on ESC (enabled by default), bootstrap error modal, close on backdrop click (enabled by default), and the close button in the header (enabled by default). These features may be disabled by setting the props, and respectively.

You can override the modal title via the named slotbootstrap error modal, override the header completely via the slot, and override the footer completely via the slot.

Note: when using the slot, bootstrap error modal, the default OK and Cancel buttons will not be present. Also, if you use the slot, the default header close button will not be present, nor can you use the slot.

Modals will not render their content in the document until they are shown (lazily rendered). Modals, when visible, are rendered appended to the element. The placement of the component will not affect layout, as it always renders as a placeholder comment node (). You can revert to the behaviour of older BootstrapVue versions via the use of the prop.

Toggle modal visibility

There are several methods that you can employ to toggle the visibility of .

Using directive

Other elements can easily show modals using the directive.

<div><b-buttonv-b-modal.my-modal>Show Modal</b-button><b-buttonv-b-modal="'my-modal'">Show Modal</b-button><b-modalid="my-modal">Hello From My Modal!</b-modal></div>

This approach will automatically return focus to the trigger element once the modal closes (similar to default Bootstrap functionality). Other approaches for toggling modal visibility may require additional code to implement this accessibility feature.

See bootstrap error modal Accessibility section below for details.

Using and instance methods

When BootstrapVue is installed as a plugin, or the plugin is used, BootstrapVue will inject a object into every Vue instance (components, apps), bootstrap error modal. exposes several methods, of which two are for showing and hiding modals:

MethodDescription
Show the modal with the specified
Hide the modal with the specified

Both methods return bootstrap error modal after being called.

<div><b-buttonid="show-btn" @click="$bvModal.show('bv-modal-example')">Open Modal</b-button><b-modalid="bv-modal-example"hide-footer><template #modal-title> Using <code>$bvModal</code> Methods </template><divclass="d-block text-center"><h3>Hello From This Modal!</h3></div><b-buttonclass="mt-3"block @click="$bvModal.hide('bv-modal-example')">Close Me</b-button></b-modal></div>

The object is also used for displaying modal message boxes.

Using, and component methods

You can access modal using attribute and then call the or methods.

<template><div><b-buttonid="show-btn" @click="showModal">Open Modal</b-button><b-buttonid="toggle-btn" @click="toggleModal">Toggle Bootstrap error modal Component Methods"><divclass="d-block text-center"><h3>Hello From My Modal!</h3></div><b-buttonclass="mt-3"variant="outline-danger"block @click="hideModal">Close Me</b-button><b-buttonclass="mt-2"variant="outline-warning"block @click="toggleModal">Toggle Me</b-button></b-modal></div></template><script>exportdefault { methods: { showModal() { this.$refs['my-modal'].show() }, bootstrap error modal, hideModal() { this.$refs['my-modal'].hide() }, toggleModal() { this.$refs['my-modal'].toggle('#toggle-btn') } } } </script>

The method accepts an optional string argument for defining what triggered the modal to close. See section Prevent Closing below for details.

Note: It is recommended to use the and methods (mentioned in the previous section) instead of using methods.

Using property

property is always bootstrap error modal synced with visible state and you can show/hide using .

<template><div><b-button @click="modalShow = !modalShow">Open Modal</b-button><b-modalv-model="modalShow">Hello From Modal!</b-modal></div></template><script>exportdefault { data() { return { modalShow: false } } } </script>

When using the prop, do not use the prop at the same time.

Using scoped slot scope methods

Refer to the Custom rendering with slots section on using the various methods passed to scoped slots for closing modals.

Emitting events on $root

You can emitbootstrap error modal,and events on with the first argument set to the modal's id. An optional second argument can specify the element to return focus to once the modal is closed, bootstrap error modal. The second argument can be a CSS selector, an element reference, or a component reference (the root bootstrap error modal of the component will be focused).

<div><b-button @click="showModal"ref="btnShow">Open Modal</b-button><b-button @click="toggleModal"ref="btnToggle">Toggle Modal</b-button><b-modalid="modal-1"><divclass="d-block">Hello From My Modal!</div><b-button @click="hideModal">Close Me</b-button><b-button @click="toggleModal">Toggle Me</b-button></b-modal></div>
exportdefault { methods: { showModal() { this.$root.$emit('bv::show::modal', bootstrap error modal, 'modal-1', '#btnShow') }, hideModal() { this.$root.$emit('bv::hide::modal', 'modal-1', bootstrap error modal, '#btnShow') windows update error code 646, toggleModal() { this.$root.$emit('bv::toggle::modal', 'modal-1', '#btnToggle') } } }

Note: It is recommended to use the and methods (mentioned in a previous section) instead of emitting events.

Prevent closing

To prevent from closing (for example when validation fails), bootstrap error modal. you can call the method of the event object passed to your (OK button), (Cancel button), (modal header close button) and event handlers, bootstrap error modal. Note thatwhen used, must be called synchronously, as async is not supported.

<template><div><b-buttonv-b-modal.modal-prevent-closing>Open Modal</b-button><divclass="mt-3"> Submitted Names: <divv-if="submittedNames.length === 0">--</div><ulv-elseclass="mb-0 pl-3"><liv-for="name in submittedNames">{{ name }}</li></ul></div><b-modalid="modal-prevent-closing"ref="modal"title="Submit Your Name" @show="resetModal" @hidden="resetModal" @ok="handleOk" ><formref="form" @submit.stop.prevent="handleSubmit"><b-form-grouplabel="Name"label-for="name-input"invalid-feedback="Name is required":state="nameState" ><b-form-inputid="name-input"v-model="name":state="nameState"required ></b-form-input></b-form-group></form></b-modal></div></template><script>exportdefault { data() { return { name: '', nameState: null, submittedNames: [] } }, methods: { bootstrap error modal checkFormValidity() { const valid = this.$refs.form.checkValidity() this.nameState = valid return valid }, resetModal() { this.name = ''this.nameState = null }, handleOk(bvModalEvent) { bvModalEvent.preventDefault() this.handleSubmit() }, bootstrap error modal, handleSubmit() { if (!this.checkFormValidity()) { return } this.submittedNames.push(this.name) this.$nextTick(() => { this.$bvModal.hide('modal-prevent-closing') }) } } } </script>

Note: events, and are emitted by modal's built in OK, Cancel, and header close (X) buttons respectively. These events will not be emitted, bootstrap error modal default, if you have provided your own buttons in the slot or have hidden the footer. In this case use the event to control cancelling of the modal close. Event is bootstrap error modal emitted, even if, and are emitted.

The, and event object () contains several properties and methods:

Property or MethodTypeDescription
MethodWhen called prevents the modal from closing
PropertyWill be one of: (Default OK Clicked), (Default Cancel clicked), (if the key was pressed), (if the backdrop was clicked), (if the header X button was clicked), the first argument provided to the method, or otherwise.
PropertyA reference to the modal element
propertyA reference to the modal's Vue VM instance
propertyThe modal's ID

You can set the value of by passing an argument to the component's method for advanced control (i.e. detecting what button or action triggered the modal to hide).

Note:,or events will be only emitted when the argument to is strictly, bootstrap error modal, or respectively. The argument passed to will be placed into the property of the event object.

Modal content

Using the grid

Utilize the Bootstrap grid system within a modal by nesting within the modal-body. Then, use the normal grid system (or ) and as you would anywhere else.

Tooltips and popovers

Tooltips and popovers can be placed within modals as needed. When modals are closed, bootstrap error modal, any tooltips and popovers within are also automatically dismissed. Tooltips and popovers are automatically appended to the modal element (to ensure correct z-indexing), although you can override where they are appended by specifying a container ID (refer to tooltip and popover docs for details).

<div><b-buttonv-b-modal.modalPopover>Show Modal</b-button><b-modalid="modalPopover"title="Modal with Popover"ok-only><p> bootstrap error modal This bootstrap error modal <b-buttonv-b-popover="'Popover inside a modal!'"title="Popover">Button</b-button> triggers a popover on click. </p><p> This <ahref="#"v-b-tooltiptitle="Tooltip in a modal!">Link</a> will show a tooltip on hover. </p></b-modal></div>

Lazy loading and static modals

By default, modals will not render their content in the document until they are shown (lazily rendered). Modals that, when visible, are rendered appended to the element. The component will not affect layout, as they render as a placeholder comment node () in the DOM position they are placed. Due to the portalling process, bootstrap error modal, it can take two or more s to render changes of the content into the target.

Modals can be rendered in-place in the document (i.e. where the component is placed in the document) by setting the prop to. Note that the content of the modal will be rendered in the DOM even if the modal is not visible/shown when is. To make modals lazy rendered, also set the prop to. The modal will then appear in the document only when it is bootstrap error modal. Note, when in mode, placement of the component may affect layout of your document and the modal.

The prop will have no effect if the prop is not (non-static modals will always be lazily rendered).

Styling, bootstrap error modal, options, and customization

Modal sizing

Modals have three optional sizes, available via the prop. These sizes kick in at certain breakpoints to avoid horizontal scrollbars on narrower viewports. Valid optional sizes are, and .

<div><b-buttonv-b-modal.modal-xlvariant="primary">xl modal</b-button><b-buttonv-b-modal.modal-lgvariant="primary">lg modal</b-button><b-buttonv-b-modal.modal-smvariant="primary">sm modal</b-button><b-modalid="modal-xl"size="xl"title="Extra Large Modal">Hello Extra Large Modal!</b-modal><b-modalid="modal-lg"size="lg"title="Large Modal">Hello Large Modal!</b-modal><b-modalid="modal-sm"size="sm"title="Small Modal">Hello Small Modal!</b-modal></div>

The prop maps the size to the classes.

Scrolling long content

When modals become too long for the user's viewport or device, they scroll independent of the page itself. Try the demo below to see what we mean.

<div><b-buttonv-b-modal.modal-tall>Launch overflowing modal</b-button><b-modalid="modal-tall"title="Overflowing Content"><pclass="my-4"v-for="i in 20":key="i"> Cras mattis consectetur purus sit amet fermentum. Cras justo odio, dapibus ac facilisis in, egestas eget quam. Morbi leo risus, porta ac consectetur ac, vestibulum at eros. </p></b-modal></div>

You can also create a scrollable modal that allows the scrolling of the modal body by setting the prop to .

<div><b-buttonv-b-modal.modal-scrollable>Launch scrolling modal</b-button><b-modalid="modal-scrollable"scrollabletitle="Scrollable Content"><pclass="my-4"v-for="i in 20":key="i"> Cras mattis consectetur purus sit amet fermentum, bootstrap error modal. Cras bootstrap error modal odio, dapibus ac facilisis in, egestas eget quam. Morbi leo risus, porta ac consectetur ac, vestibulum at eros. </p></b-modal></div>

Vertically centered modal

Vertically center your modal in the viewport by setting the prop.

<div><b-buttonv-b-modal.modal-center>Launch centered modal</b-button><b-modalid="modal-center"centeredtitle="BootstrapVue"><pclass="my-4">Vertically centered modal!</p></b-modal></div>

Feel free to mix vertically with .

Variants

Control the header, footer, and body background and text variants by setting the, bootstrap error modal,and props. Use any of the standard Bootstrap variants such as,bootstrap error modal,, etc.

The variants for the bottom border of the header and top border of the footer can be controlled by the and props respectively.

<template><div><b-button @click="show=true"variant="primary">Show Modal</b-button><b-modalv-model="show"title="Modal Variants":header-bg-variant="headerBgVariant":header-text-variant="headerTextVariant":body-bg-variant="bodyBgVariant":body-text-variant="bodyTextVariant":footer-bg-variant="footerBgVariant":footer-text-variant="footerTextVariant" ><b-containerfluid><b-rowclass="mb-1 text-center"><b-colcols="3"></b-col><b-col>Background</b-col><b-col>Text</b-col></b-row><b-rowclass="mb-1"><b-colcols="3">Header</b-col><b-col><b-form-selectv-model="headerBgVariant":options="variants" ></b-form-select></b-col><b-col><b-form-selectv-model="headerTextVariant":options="variants" ></b-form-select></b-col></b-row><b-rowclass="mb-1"><b-colcols="3">Body</b-col><b-col><b-form-selectv-model="bodyBgVariant":options="variants" ></b-form-select></b-col><b-col><b-form-selectv-model="bodyTextVariant":options="variants" ></b-form-select></b-col></b-row><b-row><b-colcols="3">Footer</b-col><b-col><b-form-selectv-model="footerBgVariant":options="variants" ></b-form-select></b-col><b-col><b-form-selectv-model="footerTextVariant":options="variants" ></b-form-select></b-col></b-row></b-container><template #modal-footer><divclass="w-100"><pclass="float-left">Modal Footer Content</p><b-buttonvariant="primary"size="sm"class="float-right" @click="show=false" > Close </b-button></div></template></b-modal></div></template><script>exportdefault { data() { return { show: false, variants: ['primary', 'secondary', 'success', 'warning', 'danger', bootstrap error modal, 'info', 'light', 'dark'], headerBgVariant: 'dark', headerTextVariant: 'light', bodyBgVariant: 'light', bodyTextVariant: 'dark', footerBgVariant: 'warning', bootstrap error modal, footerTextVariant: 'dark' } } } </script>

You can also apply arbitrary classes to the modal dialog container, content (modal window itself), header, body and footer via the, and props, respectively. The props accept either a string or array of strings.

Hiding the backdrop

Hide the modal's backdrop via setting the prop.

<div><b-buttonv-b-modal.modal-no-backdrop>Open modal</b-button><b-modalid="modal-no-backdrop"hide-backdropcontent-class="shadow"title="BootstrapVue"><pclass="my-2"> We've added the utility class <code>'shadow'</code> to the modal content for added effect. </p></b-modal></div>

Note that clicking outside of the modal will still close the modal even though the backdrop is hidden. You can disable this behaviour by setting the prop on .

Disable open and close animation

To disable the fading transition/animation when modal opens and closes, just set the prop on the component.

Fancy smaller or larger buttons in the default footer? Simply set the prop to for small buttons, or for larger buttons.

<div><b-buttonv-b-modal.modal-footer-sm>Small Footer Buttons</b-button><b-buttonv-b-modal.modal-footer-lg>Large Footer Buttons</b-button><b-modalid="modal-footer-sm"title="BootstrapVue"button-size="sm"><pclass="my-2">This modal bootstrap error modal small footer buttons</p></b-modal><b-modalid="modal-footer-lg"title="BootstrapVue"button-size="lg"><pclass="my-2">This modal has large footer buttons</p></b-modal></div>

The prop has no effect if you have provided your own footer via the slot.

You can disable the built-in footer buttons programmatically.

You can disable the Cancel and OK buttons individually by setting the and props, respectively, to. Set the prop to to re-enable the button.

To disable both Cancel and OK buttons at the same time, bootstrap error modal, simply set the prop to. Set it to to re-enable both buttons.

Custom rendering with slots

bootstrap error modal several named slots (of which some are optionally scoped) that you can use to customize the content of various sections of the modal.

SlotOptionally ScopedDescription
YesMain content of the modal
YesContent to place in the modal's title
YesContent to place in the header. Replaces the entire header including the close button
YesContent to place in the footer, bootstrap error modal. Replaces the entire footer including the button(s)
NoContent to place inside the footer OK button
NoContent to place inside the footer CANCEL button
NoContent to place inside the header CLOSE () button

The scope available to the slots that support optional scoping are:

Method or PropertyDescription
Closes the modal and fires the and events, with
Closes the modal and fires the and events, with
Closes the modal and fires the and events, with
Closes the modal and fires the event, with the (trigger is optional)
The visibility state of the modal. if the modal is visible and if not visible

Example modal using custom scoped slots

<template><b-button @click="$bvModal.show('modal-scoped')">Open Modal</b-button><b-modalid="modal-scoped"><template #modal-header="{ close }"><b-buttonsize="sm"variant="outline-danger" @click="close()"> Close Modal </b-button><h5>Modal Header</h5></template><template #default="{ hide }"><p>Modal Body with button</p><b-button @click="hide()">Hide Modal</b-button></template><template #modal-footer="{ ok, bootstrap error modal, cancel, hide }"><b>Custom Footer</b><b-buttonsize="sm"variant="success" @click="ok()"> OK </b-button><b-buttonsize="sm"variant="danger" @click="cancel()"> Cancel </b-button><b-buttonsize="sm"variant="outline-secondary" @click="hide('forget')"> Forget it </b-button></template></b-modal></template>

Multiple modal support

Unlike native Bootstrap v4, BootstrapVue supports multiple modals opened at the same time.

To disable stacking for a specific modal, bootstrap error modal, just set the prop on the component, bootstrap error modal. This will hide the modal before another modal is shown.

<div><b-buttonv-b-modal.modal-multi-1>Open First Modal</b-button><b-modalid="modal-multi-1"size="lg"title="First Modal"ok-onlyno-stacking><pclass="my-2">First Modal</p><b-buttonv-b-modal.modal-multi-2>Open Second Modal</b-button></b-modal><b-modalid="modal-multi-2"title="Second Modal"ok-only><pclass="my-2">Second Modal</p><b-buttonv-b-modal.modal-multi-3size="sm">Open Third Modal</b-button></b-modal><b-modalid="modal-multi-3"size="sm"title="Third Modal"ok-only><pclass="my-1">Third Modal</p></b-modal></div>

Notes:

  • Avoid nesting a inside anotheras it may get "constrained" to the boundaries of the parent modal dialog (specifically when static modals are used).
  • The opaque backdrop will appear progressively darker for each modal that is opened. This is expected behaviour as each backdrop is opened over top the other modals and backdrops.

Modal message boxes

BootstrapVue provides a few built in Message Box methods on the exposed object. These methods provide a way to generate simple OK and Confirm style modal messages, from anywhere in your app without having to explicitly place a component in your pages.

MethodDescription
Open a modal with as the content and a single OK button
Open a modal with as the content and CANCEL and OK buttons

The argument is an optional configuration object for adding titles and styling the Message Box modal. The object properties correspond to props, except in format instead of .

Both methods return a (requires a polyfill for IE 11 and older browser support) which resolve into a value when the modal hides. always resolves to the valuewhile resolves to either (OK button pressed), (CANCEL button pressed), or (if the modal was closed bootstrap error modal backdrop click, press, or some other means.

If is not provided, both methods will return immediately with the value .

You can use either the or async code styles (async requires modern browsers or a transpiler).

OK message box

Example OK Message boxes

<template><div><divclass="mb-2"><b-button @click="showMsgBoxOne">Simple msgBoxOk</b-button> Return value: {{ String(boxOne) }} </div><divclass="mb-1"><b-button @click="showMsgBoxTwo">msgBoxOk with options</b-button> Return value: {{ String(boxTwo) }} </div></div></template><script>exportdefault { data() { return { boxOne: '', boxTwo: '' } }, methods: { showMsgBoxOne() { this.boxOne = ''this.$bvModal.msgBoxOk('Action completed') .then(value => { this.boxOne = value }) .catch(err => { }) }, showMsgBoxTwo() { this.boxTwo = ''this.$bvModal.msgBoxOk('Data was submitted successfully', { title: 'Confirmation', size: 'sm', buttonSize: 'sm', okVariant: 'success', headerClass: 'p-2 border-bottom-0', footerClass: 'p-2 border-top-0', bootstrap error modal, centered: true }) .then(value => { this.boxTwo = value }) .catch(err => { terroristen i burgas }) } } } </script>

Confirm message box

Example Confirm Message boxes

<template><div><divclass="mb-2"><b-button @click="showMsgBoxOne">Simple msgBoxConfirm</b-button> Return value: {{ String(boxOne) }} </div><divclass="mb-1"><b-button @click="showMsgBoxTwo">msgBoxConfirm with options</b-button> Return value: {{ String(boxTwo) }} </div></div></template><script>exportdefault { data() { return { boxOne: '', boxTwo: '' } }, methods: { showMsgBoxOne() { this.boxOne = ''this.$bvModal.msgBoxConfirm('Are you sure?') .then(value => { this.boxOne = value }) .catch(err => { }) }, showMsgBoxTwo() { this.boxTwo = ''this.$bvModal.msgBoxConfirm('Please confirm that you want to delete everything.', { title: 'Please Confirm', size: 'sm', buttonSize: 'sm', okVariant: 'danger', okTitle: 'YES', bootstrap error modal cancelTitle: 'NO', footerClass: 'p-2', hideHeaderClose: false, centered: true }) .then(value => { runtime error cannot import stringchangeex this.boxTwo = value }) .catch(err => { }) } } } </script>

Message box notes

  • The injection is only available when using the full plugin or the plugin. It is not available if importing just the component, bootstrap error modal. To just import the injection, use the plugin.
  • A new injection (mixin) is created for each Vue virtual machine (i.e. each instantiated component), and is not usable via direct access to theas it needs access to the instance's and contexts.
  • Message Boxes require support in the browser. If targeting your app for older browsers, such as IE 11, please include a polyfill that provides support. If support is not detected, then the message box methods will immediately return .
  • Message Boxes are an extension source fatal error the component, bootstrap error modal, and hence support the majority of props (using format), with the exception of the following props:, bootstrap error modal,and .
  • When a (or ) is not provided in the options, the header will not be shown.
  • When a (or ) is provided in the options, the header close button bootstrap error modal not shown by default. You can enable the header close button by setting in the options.
  • Message Boxes will throw an error (promise rejection) if they are closed/destroyed before they are hidden. Always include a reject handler, event if using the async style code.
  • When using Vue Router (or similar), Message Boxes will close and reject if the route changes before the modal hides. If you wish for the message box to remain open when the route changes, use instead of .
  • Message boxes cannot be generated during Server Side Rendering (SSR).
  • The Message Box currently does not support HTML strings, however, you can pass an array of as the for fine grained control of the markup. You can use Vue's method to generate VNodes. This can also be done for the modal title (by passing VNodes to the option), OK button text (via the option), and the CANCEL button text (via the option).

Message box advanced usage

When using the or methods for generating modals, you may want the modal content to be more than just a string message. As mentioned in the message box notes section above, you can pass arrays of VNodes as the message and title for more complex content.

Use Vue's method to generate VNodes.

<template><div><b-button @click="showMsgOk">Show OK message box with custom content</b-button></div></template><script>exportdefault { methods: { showMsgOk() { const h = this.$createElement const titleVNode = h('div', { domProps: { innerHTML: 'Title from <i>HTML<i> string' } }) const messageVNode = h('div', { class: ['foobar'] }, [ h('p', { class: ['text-center'] }, [ ' Flashy ', h('strong', 'msgBoxOk'), ' message ', bootstrap error modal, ]), h('p', { class: ['text-center'] }, [h('b-spinner')]), h('b-img', { props: { src: 'https://picsum.photos/id/20/250/250', thumbnail: true, center: true, fluid: true, rounded: 'circle' } }) ]) this.$bvModal.msgBoxOk([messageVNode], { title: [titleVNode], buttonSize: 'sm', centered: true, size: 'sm' }) } } } </script>

Listening to modal changes via $root events

To listen to bootstrap error modal modal opening, use:

exportdefault { mounted() { this.$root.$on('bv::modal::show', bootstrap error modal, (bvEvent, modalId) => { console.log('Modal is about to be shown', bvEvent, modalId) }) } }

Refer to the Events section of this documentation for the full list of events emitted.

Accessibility

provides several accessibility features, bootstrap error modal, including auto focus, return focus, bootstrap error modal, keyboard (tab) focus containment, and automated attributes.

Note: The animation effect of this component is dependent on the media query. See the reduced motion section of our accessibility documentation for additional details.

Modal ARIA attributes

The and attributes will appear on the modal automatically in most cases.

  • The attribute will not be present if you have the header hidden, bootstrap error modal, or supplied your own header, or have not supplied a modal title. It is recommended to supply a title for your modals (when using the built in header). You can visually hide the header title, but still make it available to screen readers by setting the prop. If you do not have a header, you can supply a label for the modal by passing a string to the prop.
  • The attribute will always point to the modal's body content.
  • If the prop is specified with a string value, the attribute will not be rendered, even if you have a title/header for your modal.

The and props were added in version .

Auto focus on open

will autofocus the modal container when opened.

You can pre-focus an element within the by listening to the event, and call the element's method. will not attempt to autofocus if an element already has focus within the .

<b-modal @shown="focusMyElement"><div><b-button>I Don't Have Focus</b-button></div><div><b-form-input></b-form-input></div><div><b-form-inputref="focusThis"></b-form-input></div><div><b-form-input></b-form-input></div></b-modal>
exportdefault { methods: { focusMyElement() { this.$refs.focusThis.focus() } } }

Alternatively, if using form controls, you can use the prop to automatically focus a form control when the modal opens. Note that the prop will not work with if the prop is used without the prop set, as happens when the controls are mounted in the DOM.

If you want to auto focus one of the built-in modal buttons (, or the header button, you can set the prop to one of the values or and will focus the specified button if it exists. This feature is also available for modal message boxes.

Note: it is not recommended to autofocus an input or control inside of a modal for accessibility reasons, as screen reader users will not know the context of where the input is (the announcement of the modal may not be spoken), bootstrap error modal. It is best to let focus the modal's container, allowing the modal information to be spoken to the user, and then allow the user to tab into the input.

Returning focus to the triggering element

For accessibility reasons, bootstrap error modal, it is desirable to return focus to the element that triggered the opening of the modal, bootstrap error modal, when the modal closes.

will try and automatically determine which element had focus before the modal was opened, and will return the focus to that element when the modal has hidden if possible, bootstrap error modal. However, several methods and options are provided to allow you to specify the element to return focus to once the modal has hidden.

Specify return focus element via the prop

You can also specify an element to return focus to, when modal closes, bootstrap error modal, by setting the prop to one of the following:

  • A CSS Query Selector string (or an element ID prepended with )
  • A component reference (which is mounted on a focusable element, such as )
  • A reference to a DOM element that is focusable

If the passed in element is not focusable, then the browser will determine what has focus (usuallybootstrap error modal, which is not desirable)

This method for returning focus is handy when you use the methods andor the prop. Note this property takes precedence over other methods of specifying the return focus element.

Auto return focus

When is opened via the directive on an element, focus will be returned to this element automatically when closes, unless an element has been specified via the prop.

Specify return focus via event

When using the event (emitted on ), you can specify a second argument which is the element to return focus to. This argument accepts the same types as the prop.

this.$root.$emit('bv::show::modal', 'modal-1', '#focusThisOnClose')

Tip: if using a click event (or similar) to trigger modal to open, pass the event's bootstrap error modal property:

<div><b-button @click="$root.$emit('bv::show::modal', bootstrap error modal, 'modal-1', $event.target)">Open Modal</b-button></div>

Note: If the has the prop set, then the element specified via the event will be ignored.

Keyboard navigation

When tabbing through elements within aif focus attempts to leave the modal into the document, it will be brought back into the modal.

Avoid setting on elements within the modal to any value other than or. Doing so will make it difficult for people who rely on assistive technology to navigate and bootstrap error modal page content and can make some of your elements unreachable via keyboard navigation.

If some elements outside the modal need to be focusable (i.e. for TinyMCE), you can add them as CSS selectors to the prop 2.4.0+, e.g.:

<b-modalid="some-modal-id"title="Modal with TinyMCE Editor"ignore-enforce-focus-selector=".tox-tinymce-aux. moxman-window. tam-assetmanager-root" ></b-modal>

In some circumstances, you may need to disable the enforce focus feature completely, bootstrap error modal. You can do this by setting the propalthough this is highly discouraged for accessibility reasons.

directive accessibility

Notes on directive accessibility:

  • If the element is anything other than a (or component that renders a ), the ARIA will be set toand a keydown event listeners for and will be added, along with a listener.
  • If the element is anything other than a or (or a component that renders either), then a of will be added to the element to ensure accessibility, unless there is already a set.
