Dynamic Dialog

Dialogs can be created dynamically with any component as the content using a DialogService.


import DynamicDialog from 'primevue/dynamicdialog';

A single shared dialog instance is required in the application, ideal location would be defining it once at the main application template.


<DynamicDialog />

A dynamic dialog is controlled via the DialogService that needs to be installed as an application plugin.


import {createApp} from 'vue';
import DialogService from 'primevue/dialogservice';

const app = createApp(App);
app.use(DialogService);

The service is available with the useDialog function for Composition API or using the $dialog property of the application for Options API.


/* Composition API */
import { useDialog } from 'primevue/usedialog';

const dialog = useDialog();

/* Options API */
const dialog = this.$dialog;

The open function of the DialogService is used to open a Dialog. First parameter is the component to load and second one is the configuration object to customize the Dialog.


import ProductListDemo from './ProductListDemo';
import { useDialog } from 'primevue/usedialog';

const dialog = useDialog();

const showProducts = () => {
    dialog.open(ProductListDemo, {});
}

The component can also be loaded asynchronously, this approach is useful in conditional cases and to improve initial load times as well.


import { useDialog } from 'primevue/usedialog';

const dialog = useDialog();

const dynamicComponent = defineAsyncComponent(() => import('./ProductListDemo.vue'));

const showProducts = () => {
    dialog.open(dynamicComponent, {});
}

DynamicDialog uses the Dialog component internally, visit dialog for more information about the available props.


import ProductListDemo from './ProductListDemo';
import { useDialog } from 'primevue/usedialog';

const dialog = useDialog();

const showProducts = () => {
    dialog.open(ProductListDemo, {
        props: {
            header: 'Product List',
            style: {
                width: '50vw',
            },
            breakpoints:{
                '960px': '75vw',
                '640px': '90vw'
            },
            modal: true
        }
    });
}

The close function is available through a dialogRef that is injected to the component loaded by the dialog.


import { inject } from "vue";

const dialogRef = inject('dialogRef');

const closeDialog = () => {
    dialogRef.value.close();
}

Use the data property to pass parameters when opening a Dialog, the internal component can later access this data using dialogRef.


const dialog = useDialog();

const showProducts = () => {
    dialog.open(ProductListDemo, {
        data: {
            user: 'primetime'
        }
    });
}


import { inject, onMounted } from "vue";

const dialogRef = inject('dialogRef');

onMounted(() => {
    const params = dialogRef.value.data; // {user: 'primetime'}
})

Similarly when hiding a Dialog, any parameter passed to the close function is received from the onClose callback.


const dialog = useDialog();

const showProducts = () => {
    dialog.open(ProductListDemo, {
        onClose: (opt) => {
            const callbackParams = opt.data; // {selectedId: 12}
        }
    });
}


import { inject } from "vue";

const dialogRef = inject('dialogRef');

const closeDialog = () => {
    dialogRef.value.close({
        selectedId: 12
    });
}

The emits object defines callbacks to handle events emitted by the component within the Dialog.


import ProductListDemo from './ProductListDemo';
import { useDialog } from 'primevue/usedialog';

const dialog = useDialog();

const showProducts = () => {
    dialog.open(ProductListDemo, {
        onCancel: (e) => {
            console.log(e);  // {user: 'primetime'}
        }
    });
}


<script setup>
/* ProductListDemo.vue */
const emit = defineEmits(['cancel', 'save'])

function buttonClick() {
    emit('cancel', {user: 'primetime'});
}
</script>

A sample implementation to demonstrate loading components asynchronously, nested content and passing data.


<Button label="Select a Product" icon="pi pi-search" @click="showProducts" />

<DynamicDialog />
