Getting started in EJ2 TypeScript Textbox control

4 Jan 20259 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 node v14.15.0 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>
    <title>Essential JS 2 TextBox </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" />
</head>

<body>
    <div>
      <!--element which is going to render the TextBox-->
      <input id="firstName"/>
    </div>
</body>

</html>
```
    import { TextBox } from '@syncfusion/ej2-inputs'

    let inputobj: TextBox = new TextBox({
        placeholder: 'Enter Date',
    });

inputobj.appendTo('#firstName');
```

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>
            <input id="textbox" />
      </div>
```
    import { TextBox } from '@syncfusion/ej2-inputs';


    let iconTextBox: TextBox = new TextBox({
    placeholder: 'Enter Date',
    created: createHandler,
    });
    iconTextBox.appendTo('#textbox');

    function createHandler() {
       iconTextBox.addIcon('append', 'e-date-icon');
    }

```
  • Now, run the application in the browser using the following command.
npm start

Output will be as follows:

import { TextBox } from '@syncfusion/ej2-inputs';

// First TextBox without an icon
let textBoxObj: TextBox = new TextBox({
  placeholder: 'Enter Date',
});
textBoxObj.appendTo('#textbox');

// Second TextBox with an icon
let iconTextBox: TextBox = new TextBox({
  placeholder: 'Enter Date',
  created: () => {
    iconTextBox.addIcon('append', 'e-date-icon');
  },
});
iconTextBox.appendTo('#textboxicon');

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');
