Dynamic listview by loading AJAX HTML content in JavaScript (ES5) ListView control

We can set external HTML page content as template for our ListView control by making use of AJAX call.

let template: string;
let ajax: Ajax = new Ajax('./template.html', 'GET', false);
ajax.onSuccess = (e: string)=>{
    template = e;


In the below sample, we have rendered smartphone settings template from external HTML file.

var data = [
    { name: 'Network & Internet', id: '0', description: 'Wi-Fi, mobile, data usage, hotspot' },
    { name: 'Connected devices', id: '1', description: 'Bluetooth, cast, NFC' },
    { name: 'Battery', id: '2', description: '18% -4h 12m left' },
    { name: 'Display', id: '3', description: 'Wallpaper, sleep, font size' },
    { name: 'Sound', id: '4', description: 'Volume, vibration, Do Not Disturb' },
    { name: 'Storage', id: '5', description: '52% used - 15.48 GB free' }

var template;
var ajax = new ej.base.Ajax('./template.html', 'GET', true);
ajax.onSuccess = function(e){ 
    template = e;

function listfunction(){
    listViewInstance.template = template;

ajax.onFailure = function(reason){
var listViewInstance = new ej.lists.ListView({
    dataSource: data,
    headerTitle: 'Settings',
    showHeader: true,
    template: template,
    fields: {text:'name', id: 'id'}
