Predefined Dialog Component

Purpose: Imperative alert, confirm, and prompt dialogs opened via the DialogUtility class. No component instance required—perfect for simple notifications and user confirmations.

Package: @syncfusion/ej2-popups

Quick Example - Alert

import { DialogUtility } from '@syncfusion/ej2-popups';

let dialogObj: any = DialogUtility.alert({
  title: 'Low Battery',
  content: '10% of battery remaining',
  width: '250px',
  okButton: { click: () => dialogObj.hide() }
});

Quick Example - Confirm

import { DialogUtility } from '@syncfusion/ej2-popups';

let dialogObj: any = DialogUtility.confirm({
  title: 'Delete File',
  content: 'Are you sure you want to delete this file?',
  okButton: { 
    text: 'Delete',
    click: () => { /* delete logic */ dialogObj.hide(); }
  },
  cancelButton: { 
    text: 'Cancel',
    click: () => dialogObj.hide() 
  }
});

Quick Example - Prompt

import { DialogUtility } from '@syncfusion/ej2-popups';

let dialogObj: any = DialogUtility.confirm({
  title: 'Enter Name',
  content: '<input id="nameInput" class="e-input" placeholder="Your name" />',
  okButton: {
    text: 'Submit',
    click: () => {
      const name: string = (document.getElementById('nameInput') as HTMLInputElement).value;
      console.log('Name:', name);
      dialogObj.hide();
    }
  }
});

Tooltip Component

Purpose: Displays contextual popup information when users hover, focus, or click on target elements. Supports 12 positions, multiple open modes, animations, custom content, and full accessibility.

Package: @syncfusion/ej2-popups

Quick Example

import { Tooltip } from '@syncfusion/ej2-popups';

let tooltip: Tooltip = new Tooltip({
  content: 'Tooltip Content',
  position: 'TopCenter'
});
tooltip.appendTo('#target');

Quick Example - Multiple Targets

import { Tooltip } from '@syncfusion/ej2-popups';

let tooltip: Tooltip = new Tooltip({
  target: '.e-info',
  position: 'RightCenter'
});
tooltip.appendTo('#container');

HTML:

<div id="container">
  <input type="text" class="e-info" title="Please enter your name" />
  <input type="email" class="e-info" title="Enter a valid email address" />
</div>
