Getting started in EJ2 TypeScript Tab control
2 Jun 202322 minutes to read
This section briefly explains about how to create a simple JavaScript Tab using TypeScript and configure the Tab header content using Essential JS 2 quickstart seed repository.
Dependencies
The following is the list of dependencies required to use the Tab component in your application.
|-- @syncfusion/ej2-navigations
|-- @syncfusion/ej2-base
|-- @syncfusion/ej2-buttons
|-- @syncfusion/ej2-popups
Installation and configuration
- Clone the Essential JS 2 quickstart application project from GitHub and install necessary npm packages using the following command.
git clone https://github.com/syncfusion/ej2-quickstart.git quickstart
cd quickstart
npm install
By default, the project is configured with all the Essential JS 2 dependencies. For better understanding, remove all the dependencies from
src/system.config.js
to get started with the Tab component.
- Refer to the Tab component dependencies in
system.config.js
configuration file.
[src/system.config.js]
System.config({
paths: {
'syncfusion:': './node_modules/@syncfusion/',
},
map: {
app: 'app',
//Syncfusion packages mapping
"@syncfusion/ej2-base": "syncfusion:ej2-base/dist/ej2-base.umd.min.js",
"@syncfusion/ej2-buttons": "syncfusion:ej2-buttons/dist/ej2-buttons.umd.min.js",
"@syncfusion/ej2-data": "syncfusion:ej2-data/dist/ej2-data.umd.min.js",
"@syncfusion/ej2-inputs": "syncfusion:ej2-inputs/dist/ej2-inputs.umd.min.js",
"@syncfusion/ej2-lists": "syncfusion:ej2-lists/dist/ej2-lists.umd.min.js",
"@syncfusion/ej2-navigations": "syncfusion:ej2-navigations/dist/ej2-navigations.umd.min.js",
"@syncfusion/ej2-popups": "syncfusion:ej2-popups/dist/ej2-popups.umd.min.js",
"@syncfusion/ej2-splitbuttons": "syncfusion:ej2-splitbuttons/dist/ej2-splitbuttons.umd.min.js"
},
packages: {
'app': { main: 'app', defaultExtension: 'js' }
}
});
System.import('app');
- The Tab CSS files are available in the ej2-navigations package folder. This can be referenced in your application using the following code.
[src/styles/styles.css]
@import '../../node_modules/@syncfusion/ej2-base/styles/material.css';
@import '../../node_modules/@syncfusion/ej2-buttons/styles/material.css';
@import '../../node_modules/@syncfusion/ej2-popups/styles/material.css';
@import '../../node_modules/@syncfusion/ej2-navigations/styles/material.css';
Initialize the Tab using JSON items collection
The Tab can be rendered by defining a JSON array. The item is rendered with header
text and content
for each Tab using items
property.
- Add the HTML div tag with its id attribute as
element
in yourindex.html
file to initialize the Tab.
[src/index.html]
<!DOCTYPE html>
<html lang="en">
<head>
<title>Essential JS 2 Tab</title>
<meta charset="utf-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0, user-scalable=no" />
<meta name="description" content="Essential JS 2" />
<meta name="author" content="Syncfusion" />
<link rel="shortcut icon" href="resources/favicon.ico" />
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet" />
<!--style reference from app-->
<link href="/styles/styles.css" rel="stylesheet" />
<!--system js reference and configuration-->
<script src="node_modules/systemjs/dist/system.src.js" type="text/javascript"></script>
<script src="system.config.js" type="text/javascript"></script>
</head>
<body>
<div style="margin: 50px;">
<!--element which is going to render-->
<div id="element">
</div>
</body>
</html>
- Import the Tab component to your
app.ts
file and initialize it to the#element
as shown below.
[src/app/app.ts]
import { Tab } from '@syncfusion/ej2-navigations';
let tabObj: Tab = new Tab({
items: [
{
header: { 'text': 'Twitter' },
content: 'Twitter is an online social networking service that enables users to send and read short 140-character ' +
'messages called "tweets". Registered users can read and post tweets, but those who are unregistered can only read ' +
'them. Users access Twitter through the website interface, SMS or mobile device app Twitter Inc. is based in San ' +
'Francisco and has more than 25 offices around the world. Twitter was created in March 2006 by Jack Dorsey, ' +
'Evan Williams, Biz Stone, and Noah Glass and launched in July 2006. The service rapidly gained worldwide popularity, ' +
'with more than 100 million users posting 340 million tweets a day in 2012.The service also handled 1.6 billion ' +
'search queries per day.'
},
{
header: { 'text': 'Facebook' },
content: 'Facebook is an online social networking service headquartered in Menlo Park, California. Its website was ' +
'launched on February 4, 2004, by Mark Zuckerberg with his Harvard College roommates and fellow students Eduardo ' +
'Saverin, Andrew McCollum, Dustin Moskovitz and Chris Hughes.The founders had initially limited the website\'\s ' +
'membership to Harvard students, but later expanded it to colleges in the Boston area, the Ivy League, and Stanford ' +
'University. It gradually added support for students at various other universities and later to high-school students.'
},
{
header: { 'text': 'WhatsApp' },
content: 'WhatsApp Messenger is a proprietary cross-platform instant messaging client for smartphones that operates ' +
'under a subscription business model. It uses the Internet to send text messages, images, video, user location and ' +
'audio media messages to other users using standard cellular mobile numbers. As of February 2016, WhatsApp had a user ' +
'base of up to one billion,[10] making it the most globally popular messaging application. WhatsApp Inc., based in ' +
'Mountain View, California, was acquired by Facebook Inc. on February 19, 2014, for approximately US$19.3 billion.'
}
]
});
tabObj.appendTo('#element');
- Run the application in the browser using the following command.
npm start
Output will be as follows:
import { Tab } from '@syncfusion/ej2-navigations';
let tabObj: Tab = new Tab({
items: [
{
header: { 'text': 'Twitter' },
content: 'Twitter is an online social networking service that enables users to send and read short 140-character ' +

Initialize the Tab using HTML elements
The Tab component can be rendered based on the given HTML element using id
as target
.
Header section must be enclosed with in a wrapper element using e-tab-header

class.
You need to follow the below structure of HTML elements to render the Tab,
<div id='tab_html_markup'> --> Root Tab element
<div class="e-tab-header"> --> Tab header
<div> --> Header Item
</div>
</div>
<div class="e-content"> --> Tab content
<div> --> Content Item
