20 Jan 20248 minutes to read

This section briefly explains how to create a simple JavaScript DatePicker 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 is required to use DatePicker component in your application.

|-- @syncfusion/ej2-calendars
  |-- @syncfusion/ej2-base
  |-- @syncfusion/ej2-data
  |-- @syncfusion/ej2-inputs
    |-- @syncfusion/ej2-splitbuttons
  |-- @syncfusion/ej2-lists
  |-- @syncfusion/ej2-popups
    |-- @syncfusion/ej2-buttons

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 the DatePicker component, need to import DatePicker and its dependent component’s styles as given below in the ~/src/styles/styles.css file, as shown below:

style.css
@import "../../node_modules/@syncfusion/ej2-base/styles/material.css";
@import "../../node_modules/@syncfusion/ej2-buttons/styles/material.css";
@import "../../node_modules/@syncfusion/ej2-inputs/styles/material.css";
@import "../../node_modules/@syncfusion/ej2-popups/styles/material.css";
@import "../../node_modules/@syncfusion/ej2-calendars/styles/material.css";

Add DatePicker to the application

Add the HTML input element for DatePicker into your index.html file.

[src/index.html]

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

<head>
    <title>Essential JS 2 DatePicker component</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 style="margin: 50px;">
        <!--element which is going to render the DatePicker-->
        <input id="element"/>
    </div>

</body>

</html>

Now import the DatePicker component into your app.ts and append it to #element
[src/app/app.ts]

app.ts
import { DatePicker } from '@syncfusion/ej2-calendars';

// initialize datepicker component
let datepickerObject: DatePicker = new DatePicker();
// render initialized datepicker
datepickerObject.appendTo('#element');

Run the application

Now use the npm run start command to run the application in the browser.

npm run start

The below example shows a basic DatePicker.

index.ts
index.html
import { DatePicker } from '@syncfusion/ej2-calendars';
// creates a simple datepicker component
let datepickerObject: DatePicker = new DatePicker({
    // sets the placeholder
    placeholder: 'Enter date'
});
datepickerObject.appendTo('#element');

Setting the value, min and max dates

The following example demonstrates how to set the value, min and max dates on initializing the DatePicker. Here you can able to select a date within a range from 9th to 15th.

index.ts
index.html
import { DatePicker } from '@syncfusion/ej2-calendars';

let month: number = new Date().getMonth();
let fullYear: number = new Date().getFullYear();
// creates a datepicker with min max property
let datepickerObject: DatePicker = new DatePicker({
    // Sets the min.
    min: new Date(fullYear, month , 9),
    //Sets the max.
    max: new Date(fullYear, month, 15),
    // Sets the value.
    value: new Date(fullYear, month , 11)
});
datepickerObject.appendTo('#element');
