Getting started in EJ2 TypeScript Textbox control
3 Nov 202313 minutes to read
This section explains how to create a simple TextBox component and configure its available functionalities in TypeScript, using Essential JS 2 quickstart seed repository.
This application is integrated with the
webpack.config.js
configuration and uses the latest version of the webpack-cli. It requires nodev14.15.0
or higher. For more information about webpack and its features, refer to the webpack documentation.
Dependencies
The following list of dependencies are required to use the TextBox component in your application.
|-- @syncfusion/ej2-inputs
|-- @syncfusion/ej2-base
Set up development environment
Open the command prompt from the required directory, and run the following command to clone the Syncfusion JavaScript (Essential JS 2) quickstart project from GitHub.
git clone https://github.com/SyncfusionExamples/ej2-quickstart-webpack- ej2-quickstart
After cloning the application in the ej2-quickstart
folder, run the following command line to navigate to the ej2-quickstart
folder.
cd ej2-quickstart
Add Syncfusion JavaScript packages
Syncfusion JavaScript (Essential JS 2) packages are available on the npmjs.com public registry. You can install all Syncfusion JavaScript (Essential JS 2) controls in a single @syncfusion/ej2 package or individual packages for each control.
The quickstart application is preconfigured with the dependent @syncfusion/ej2 package in the ~/package.json
file. Use the following command to install the dependent npm packages from the command prompt.
npm install
Import the Syncfusion CSS styles
To render TextBox component, need to import inputs and its dependent components styles as given below in the ~/src/styles/styles.css
file, as shown below:
@import '../../node_modules/@syncfusion/ej2-base/styles/material.css';
@import '../../node_modules/@syncfusion/ej2-inputs/styles/material.css';
Adding TextBox to the application
Add the HTML Input element with e-input
class into your index.html
.
[src/index.html]
<!DOCTYPE html>
<html lang="en">
<head>

<meta charset="utf-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0, user-scalable=no" />

</head>
<body>
<div>
<!--element which is going to render the TextBox-->
<input class="e-input" type="text" placeholder="Enter Date" />
</div>
</body>
</html>
Adding icons to the TextBox
You can create a TextBox with icon as a group by creating the parent div element with the class e-input-group
and add the icon element as span with the class e-input-group-icon
. For detailed information, refer to the Groups section.
<!--element which is going to render the TextBox with date icon-->
<div class="e-input-group">
<input class="e-input" name='input' type="text" placeholder="Enter Date"/>
<span class="e-input-group-icon e-input-popup-date"></span>
</div>
- Now, run the application in the browser using the following command.
npm start
Output will be as follows:
// To get the all input fields and its container.
let inputElement = document.querySelectorAll('.e-input-group .e-input,.e-float-input.e-input-group input');
// Add 'e-input-focus' class to the input for achive ripple effect when focus on the input field.
for (let i = 0; i < inputElement.length; i++) {
inputElement[i].addEventListener("focus", function () {
let parentElement = this.parentNode;
if (parentElement.classList.contains('e-input-in-wrap')) {
parentElement.parentNode.classList.add('e-input-focus');
} else {
this.parentNode.classList.add('e-input-focus');
}
});
inputElement[i].addEventListener("blur", function () {
let parentElement = this.parentNode;
if (parentElement.classList.contains('e-input-in-wrap')) {
parentElement.parentNode.classList.remove('e-input-focus');
} else {
this.parentNode.classList.remove('e-input-focus');
}
});
}
// Add 'e-input-btn-ripple' class to the icon element for achive ripple effect when click on the icon.
var inputIcon = document.querySelectorAll('.e-input-group-icon');
for (let i = 0; i < inputIcon.length; i++) {
inputIcon[i].addEventListener('mousedown', function () {
this.classList.add('e-input-btn-ripple');
});
inputIcon[i].addEventListener('mouseup', function () {
let element = this;
setTimeout(function () {
element.classList.remove('e-input-btn-ripple');
}, 500);
});
}

Floating label
The floating label TextBox floats the label above the TextBox after focusing, or filled with value in the TextBox.
You can create the floating label TextBox by using the floatLabelType API.
import { TextBox } from '@syncfusion/ej2-inputs'
let inputobj: TextBox = new TextBox({
placeholder: 'First Name',
floatLabelType: 'Auto'
});
inputobj.appendTo('#firstName');
