ConfirmDialog

ConfirmDialog is backed by a service utilizing Observables to display confirmation windows easily that can be shared by multiple actions on the same component.

Import #


import { ConfirmDialogModule } from 'primeng/confirmdialog';

Basic #

ConfirmDialog is defined using p-confirmDialog tag and an instance of ConfirmationService is required to display it bycalling confirm method.


<p-toast></p-toast>
<p-confirmDialog [style]="{width: '50vw'}"></p-confirmDialog>
<p-button (click)="confirm1()" icon="pi pi-check" label="Confirm"></p-button>
<p-button (click)="confirm2()" icon="pi pi-times" label="Delete" class="p-button-danger"></p-button>

Position #

The position property of the confirm options is used to display a Dialog at all edges and corners of the screen.


<p-toast></p-toast>
<p-confirmDialog [style]="{ width: '50vw' }" key="positionDialog" [position]="position" rejectButtonStyleClass="p-button-outlined"></p-confirmDialog>
<div class="flex flex-wrap justify-content-center gap-2">
    <p-button (click)="confirmPosition('left')" icon="pi pi-arrow-right" label="Left" styleClass="p-button-help"></p-button>
    <p-button (click)="confirmPosition('right')" icon="pi pi-arrow-left" label="Right" styleClass="p-button-help"></p-button>
</div>
<div class="flex flex-wrap justify-content-center gap-2">
    <p-button (click)="confirmPosition('top-left')" icon="pi pi-arrow-down" label="TopLeft" styleClass="p-button-warning"></p-button>
    <p-button (click)="confirmPosition('top')" icon="pi pi-arrow-down" label="Top" styleClass="p-button-warning"></p-button>
    <p-button (click)="confirmPosition('top-right')" icon="pi pi-arrow-down" label="TopRight" styleClass="p-button-warning"></p-button>
</div>
<div class="flex flex-wrap justify-content-center gap-2">
    <p-button (click)="confirmPosition('bottom-left')" icon="pi pi-arrow-up" label="BottomLeft" styleClass="p-button-success"></p-button>
    <p-button (click)="confirmPosition('bottom')" icon="pi pi-arrow-up" label="Bottom" styleClass="p-button-success"></p-button>
    <p-button (click)="confirmPosition('bottom-right')" icon="pi pi-arrow-up" label="BottomRight" styleClass="p-button-success"></p-button>
</div>

Template #

Properties of the dialog are defined in two ways, message, icon, header properties can either be defined using confirm method or declaratively on p-confirmDialog ng-template by header, message, icon and footer templates. If these values are unlikely to change then declarative approach would be useful, still properties defined in a ng-template can be overridden with confirm method call.

In addition, buttons at footer section can be customized by passing your own UI, important note to make confirmation work with a custom UI is defining a local ng-template variable for the dialog and assign accept()-reject() methods to your own buttons.


<p-toast></p-toast>
<p-confirmDialog #cd [style]="{ width: '50vw' }">
    <ng-template pTemplate="header">
        <h3>Header Content</h3>
    </ng-template>
    <ng-template pTemplate="icon">
        <i class="pi pi-user"></i>
    </ng-template>
    <ng-template pTemplate="message">
        <p>Message Template</p>
    </ng-template>
    <ng-template pTemplate="footer">
        <button type="button" pButton icon="pi pi-times" label="No" (click)="cd.reject()"></button>
        <button type="button" pButton icon="pi pi-check" label="Yes" (click)="cd.accept()"></button>
    </ng-template>
</p-confirmDialog>
<p-button (click)="confirm1()" icon="pi pi-check" label="Confirm"></p-button>

Style #

Following is the list of structural style classes, for theming classes visit theming page.

Name	Element
p-dialog	Container element
p-confirmdialog	Container element
p-dialog-titlebar	Container of header.
p-dialog-title	Header element.
p-dialog-titlebar-icon	Icon container inside header.
p-dialog-titlebar-close	Close icon element.
p-dialog-content	Content element.

Accessibility #

Screen Reader

ConfirmDialog component uses alertdialog role along with aria-labelledby referring to the header element however any attribute is passed to the root element so you may use aria-labelledby to override this default behavior. In addition aria-modal is added since focus is kept within the popup.

It is recommended to use a trigger component that can be accessed with keyboard such as a button, if not adding tabIndex would be necessary.

When confirm function is used and a trigger is passed as a parameter, ConfirmDialog adds aria-expanded state attribute and aria-controls to the trigger so that the relation between the trigger and the popup is defined.


confirm1() {
this.confirmationService.confirm({
    message: 'Are you sure that you want to proceed?',
    header: 'Confirmation',
    icon: 'pi pi-exclamation-triangle',
    accept: () => acceptFunc(),
    reject: () => rejectFunc()
});

<p-button (click)="confirm1()" icon="pi pi-check" label="Confirm"></p-button>

<p-confirmDialog></p-confirmDialog>

If the dialog is controlled with the visible property aria-expanded and aria-controls need to be handled explicitly.


<p-confirmDialog 
    id="dialog" 
    [visible]="visible" 
    (onHide)="visible = false" 
    message="Are you sure you want to proceed?" 
    header="Confirmation" 
    icon="pi pi-exclamation-triangle"
></p-confirmDialog>

<p-button 
    (click)="visible = true" 
    icon="pi pi-check" 
    label="Confirm" 
    aria-controls="{{visible ? 'dialog' : null}} 
    aria-expanded="{{visible ? true : false}}"
></p-button>
