3 Nov 20237 minutes to read

This section explains how to create a simple MaskedTextBox 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 MaskedTextBox 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 MaskedTextBox 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-buttons/styles/material.css';
@import '../../node_modules/@syncfusion/ej2-popups/styles/material.css';
@import '../../node_modules/@syncfusion/ej2-splitbuttons/styles/material.css';
@import '../../node_modules/@syncfusion/ej2-inputs/styles/material.css';

Add MaskedTextBox to the project

Add the HTML input element that needs to be rendered as MaskedTextBox in the index.html file.

[src/index.html]

<!DOCTYPE html>
<html lang="en">

<head>
    <title>Essential JS 2 MaskedTextBox</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 MaskedTextBox" />
    <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 style="margin: 50px;">
        <!--input element which needs to be rendered/converted as MaskedTextBox-->
        <input id="mask" type="text" />
    </div>

</body>

</html>

Import the MaskedTextBox component into your app.ts and append it to the element #mask as shown in the following.

[src/app/app.ts]

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

// initializes the MaskedTextBox component
let mask: MaskedTextBox = new MaskedTextBox();

mask.appendTo('#mask');

Set the mask

You can set the mask to the MaskedTextBox to validate the user input by using the mask property. To know more about the usage of mask and configuration, refer to this link.

The following example demonstrates the usage of mask element 0 that allows any single digit from 0 to 9.

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

// initializes the MaskedTextBox component
let mask: MaskedTextBox = new MaskedTextBox({
        // sets mask format to the MaskedTextBox
        mask: '000-000-0000'
});

mask.appendTo('#mask');

Run the application

Use the npm run start command to run the application in the browser.

npm run start

The following example shows the MaskedTextBox with the mask element 0.

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

// initializes the MaskedTextBox component
let mask: MaskedTextBox = new MaskedTextBox({
        // sets mask format to the MaskedTextBox
        mask: '000-000-0000',
        placeholder: 'MaskedTextBox',
        floatLabelType: 'Always'
});

mask.appendTo('#mask');
