This is a Vue.js wrapper component for [email protected] (demo) using [email protected].
npm install vue-a11y-dialogIn your main.js application file, install the component:
import VueA11yDialog from 'vue-a11y-dialog'
Vue.use(VueA11yDialog)Then use it as follows:
<template>
<div id="app">
<!-- ... -->
<button type="button" @click="openDialog">
Open dialog
</button>
<a11y-dialog
id="app-dialog"
app-root="#app"
dialog-root="#dialog-root"
@dialog-ref="assignDialogRef"
>
<template v-slot:title>
<span>Your dialog title</span>
</template>
<div>
<p>Your content</p>
</div>
</a11y-dialog>
</div>
</template>export default {
name: 'YourComponent',
data: () => ({
dialog: null
}),
methods: {
openDialog () {
if (this.dialog) {
this.dialog.show()
}
},
assignDialogRef (dialog) {
this.dialog = dialog
}
}
}In your index.html, add a container where your dialog will be rendered into.
<!DOCTYPE html>
<html>
<body>
<div id="app"></div>
<!-- built files will be auto injected -->
<div id="dialog-root"></div>
</body>
</html>It's important to assign the direct reference to the dialog instance via @dialog-ref, otherwise there is no way to call its methods.
Alternatively, you can also import the component directly into your file without installing it first:
import { A11yDialog } from 'vue-a11y-dialog'
export default {
name: 'YourComponent',
components: {
'a11y-dialog': A11yDialog
},
methods: {
// ...
}
}It's possible to use multiple dialogs in the same component, just make sure to assign the different dialog instances separately.
In your <template>:
<template>
<div id="app">
<!-- First dialog -->
<a11y-dialog
id="first-dialog"
app-root="#app"
dialog-root="#dialog-root"
@dialog-ref="dialog => assignDialogRef('first', dialog)"
>
<template v-slot:title>
<span>First dialog title</span>
</template>
<div>
<p>Your content</p>
</div>
</a11y-dialog>
<!-- Second dialog -->
<a11y-dialog
id="second-dialog"
app-root="#app"
dialog-root="#dialog-root"
@dialog-ref="dialog => assignDialogRef('second', dialog)"
>
<template v-slot:title>
<span>Second dialog title</span>
</template>
<div>
<p>Your content</p>
</div>
</a11y-dialog>
</div>
</template>In your <script>:
import { A11yDialog } from 'vue-a11y-dialog'
export default {
name: 'YourComponent',
data: () => ({
dialogs: {}
}),
methods: {
assignDialogRef (type, dialog) {
this.dialogs[type] = dialog
}
}
