Getting started in EJ2 JavaScript Textbox control

10 Feb 202612 minutes to read

This section explains the steps required to create a simple Essential® JS 2 Textbox and demonstrate the basic usage of the Textbox control in a JavaScript application.

Dependencies

The list of dependencies required to use the Textbox component in your application is given below:

|-- @syncfusion/ej2-inputs
    |-- @syncfusion/ej2-base

Setup for local environment

Refer to the following steps to set up your local environment.

Step 1: Create a root folder named my-app for your application.

Step 2: Create a my-app/resources folder to store local scripts and styles files.

Step 3: Open Visual Studio Code and create my-app/index.js and my-app/index.html files to initialize the Essential® JS 2 Textbox control.

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 TextBox component.

[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-inputs": "syncfusion:ej2-inputs/dist/ej2-inputs.umd.min.js",
    },
    packages: {
        'app': { main: 'app', defaultExtension: 'js' }
    }
});

System.import('app');
  • The TextBox CSS files are available in the ej2-inputs 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-inputs/styles/material.css';

The Custom Resource Generator (CRG) is an online web tool that generates custom scripts and styles for specific components. This tool combines required component scripts and styles into a single file.

Adding TextBox to the application

Add an HTML input element with the e-input class to your index.html file.

[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" />

    <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>
      <!--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>
          <input id="textbox" />
      </div>
```
    var iconTextBox = new ej.inputs.TextBox({
        placeholder: 'Enter Date',
        created: createHandler,
    });
    iconTextBox.appendTo('#textbox');

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

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

Output will be as follows:

ej.base.enableRipple(true);

var iconTextBox = new ej.inputs.TextBox({
    placeholder: 'First Name',
    floatLabelType: 'Auto',
    created: function() {
        iconTextBox.addIcon('append', 'e-icons e-date-range');
    }
});
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.

var inputobj = new ej.inputs.TextBox({
        placeholder: 'First Name',
        floatLabelType: 'Auto'
    });
inputobj.appendTo('#firstName');
