Template in EJ2 JavaScript Dialog control

8 May 20236 minutes to read

In Dialog the template support is provided to the header and footer sections. So any text or HTML content can be appending in these sections.

The Dialog header content can be provided through the header property, and it will allow both text and any HTML content as a string. Also in header, close button is provided as built-in support, and this can be enabled through the showCloseIcon property.

The Dialog footer can be enabled by adding built-in buttons or providing any HTML string through the footerTemplate.

The buttons and footerTemplate properties can’t be used at the same time.


The Dialog content can be provided through the content property, and it accepts both text and HTML string as content.

The below example demonstrates the usage of header, footer and content templates in the Dialog control.

* Dialog template sample

var icontemp = '<button id="sendButton" class="e-control e-btn e-primary" data-ripple="true">' + 'Send</button>';
var headerimg = '<img class="img2" style="display: inline-block;" src="https://ej2.syncfusion.com/products/typescript/dialog/template/images/1.png" alt="header image">';
var sendbutton = new ej.buttons.Button();
var proxy = this;

// Initialize Dialog component
var dialog = new ej.popups.Dialog({
    // Enables the header with template content
    header: headerimg + '<div class="dlg-template" title="Nancy" class="e-icon-settings"> Nancy </div>',
    // Enables the footer with template content
    footerTemplate: ' <input id="inVal" class="e-input" type="text" placeholder="Enter your message here!"/>' + icontemp,
    // Dialog content
    content: document.getElementById("dlgContent"),
    // Enables the close icon button in header
    showCloseIcon: true,
    // The Dialog shows within the target element
    target: document.getElementById("container"),
    //Dialog width
    width: '400px',
    height: '250px',
    beforeOpen: onBeforeopen
// Render initialized Dialog

// Sample level code to handle the button click action
document.getElementById('targetButton').onclick = function () {
    // Call the show method to open the Dialog

document.getElementById('sendButton').onkeydown = function (e) {
    if (e.keyCode === 13) {

document.getElementById('inVal').onkeydown = function (e) {
    if (e.keyCode === 13) {

document.getElementById('sendButton').onclick = function () {

function onBeforeopen() {
    document.getElementById('dlgContent').style.visibility = 'visible';

function updateTextValue() {
    var enteredVal = document.getElementById('inVal');
    var dialogTextElement = document.getElementsByClassName('dialogText')[0];
    var dialogTextWrap = document.getElementsByClassName('dialogContent')[0];
    if (enteredVal.value !== '') {
        dialogTextElement.innerHTML = enteredVal.value;
        enteredVal.value = '';
