30 Sep 202610 minutes to read
This section explains the steps required to create a simple Essential® JS 2 DateRangePicker and demonstrate the basic usage of the DateRangePicker control in a JavaScript application.
Dependencies
The list of dependencies required to use the DateRangePicker component in an application is given below:
|-- @syncfusion/ej2-calendars
|-- @syncfusion/ej2-base
|-- @syncfusion/ej2-inputs
|-- @syncfusion/ej2-splitbuttons
|-- @syncfusion/ej2-lists
|-- @syncfusion/ej2-data
|-- @syncfusion/ej2-popups
|-- @syncfusion/ej2-buttonsSetup 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 DateRangePicker control.
Adding Syncfusion® resources
The Essential® JS 2 DateRangePicker control can be initialized by using either of the following ways.
- Using local script and style.
- Using CDN link for script and style.
Using local script and style references in a HTML page
Step 1: You can get the global scripts and styles from the Essential Studio® JavaScript (Essential® JS 2) build installed location.
Step 2: To render the DateRangePicker component, need to add the DateRangePicker and its dependent packages from below installed location.

Syntax:
package:
**(installed location)**/Syncfusion/Essential Studio/{RELEASE_VERSION}/Essential JS 2/{PACKAGE_NAME
Example:
Package:
C:/Program Files (x86)/Syncfusion/Essential Studio/15.4.30/Essential JS 2/ej2-basepackages:
C:/Program Files (x86)/Syncfusion/Essential Studio/15.4.30/Essential JS 2/ej2-buttonspackages:

Step 3: Create a folder myapp/resources and copy/paste the global scripts and styles from the above installed location to myapp/resources location.
Step 4: Create a HTML page (index.html) in myapp location and add the Essential® JS 2 script and style references.

</html>If you want to refer the combined component styles, please make use of our
CRG(Custom Resource Generator) in your application.
Step 5: Now, add the input element and initiate the Essential® JS 2 DateRangePicker component in the index.html by using the following code
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>Essential JS 2 DateRangePicker Component</title>
<!-- Essential JS 2 DateRangePicker's dependent material theme -->
<link href="//cdn.syncfusion.com/ej2/ej2-base/styles/material.css" rel="stylesheet" type="text/css" />
<link href="//cdn.syncfusion.com/ej2/ej2-buttons/styles/material.css" rel="stylesheet" type="text/css" />
<link href="//cdn.syncfusion.com/ej2/ej2-calendars/styles/material.css" rel="stylesheet" type="text/css" />
<!-- Essential JS 2 all script -->
<!-- <script src="https://cdn.syncfusion.com/ej2/dist/ej2.min.js" type="text/javascript"></script> -->
<!-- Essential JS 2 DateRangePicker's dependent scripts -->
<script src="//cdn.syncfusion.com/ej2/ej2-base/dist/global/ej2-base.min.js" type="text/javascript"></script>
<script src="//cdn.syncfusion.com/ej2/ej2-inputs/dist/global/ej2-inputs.min.js" type="text/javascript"></script>
<script src="//cdn.syncfusion.com/ej2/ej2-buttons/dist/global/ej2-buttons.min.js" type="text/javascript"></script>
<script src="//cdn.syncfusion.com/ej2/ej2-lists/dist/global/ej2-lists.min.js" type="text/javascript"></script>
<script src="//cdn.syncfusion.com/ej2/ej2-popups/dist/global/ej2-popups.min.js" type="text/javascript"></script>
<script src="//cdn.syncfusion.com/ej2/ej2-calendars/dist/global/ej2-calendars.min.js" type="text/javascript"></script>
</head>
<body>
<!-- Add the HTML <input> element -->
<input id="element" />
<script>
// initialize DateRangePicker component
var DateRangePicker = new ej.calendars.DateRangePicker();
// Render initialized DateRangePicker.
DateRangePicker.appendTo('#element')
</script>
</body>
</html>Step 6: Now, run the index.html in web browser, it will render the Essential® JS 2 DateRangePicker component.
Using CDN link for script and style reference
Step 1: The Essential® JS 2 components scripts and styles are already hosted in the below CDN link formats.
Syntax:
Script:
http://cdn.syncfusion.com/ej2/{PACKAGE_NAME}/dist/global/{PACKAGE_NAME}.min.jsStyle:
http://cdn.syncfusion.com/ej2/{PACKAGE_NAME}/styles/material.css
Example:
Script:
http://cdn.syncfusion.com/ej2/ej2-calendars/dist/global/ej2-calendars.min.jsStyles:
http://cdn.syncfusion.com/ej2/ej2-calendars/styles/material.css
Step 2: Add the CDN global script and styles for calendar and its dependent packages in myapp/index.html as shown below.
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>Essential JS 2 DateRangePicker Component</title>

<link href="//cdn.syncfusion.com/ej2/ej2-calendars/styles/material.css" rel="stylesheet" type="text/css" />
<!-- Essential JS 2 all script -->

<script src="//cdn.syncfusion.com/ej2/ej2-calendars/dist/global/ej2-calendars.min.js" type="text/javascript"></script>
</head>
<body>
<!-- Add the HTML <input> element -->
<input id="element" />
<script>
// initialize DateRangePicker component
var DateRangeObj = new ej.calendars.DateRangePicker();
// Render initialized DateRangePicker.
DateRangeObj.appendTo('#element')
</script>
</body>
</html>When referencing CDN links in application, always ensure the network connection will be in enabled state.
Setting the start and end date
The start and end date in a range can be defined with the help of startDate and endDate property.
The following example demonstrates to set the start and end date on initializing the
DateRangePicker.
var daterangepicker = new ej.calendars.DateRangePicker({
placeholder: 'Select a range',
//sets the start date in the range
startDate: new Date("11/9/2017"),
//sets the end date in the range
endDate: new Date("11/21/2017")
});
daterangepicker.appendTo('#element');<!DOCTYPE html><html lang="en"><head>

</body></html>The DateRangePicker component follows a commit-on-Enter/focus-out scenario. The underlying value is updated only when the user commits the edit by pressing Enter or moving focus away (blur). The refresh method rebuilds the component using the last committed value. If
refreshis invoked—either directly or indirectly via ResizeObserver callbacks, layout shifts, or dynamic validation updates—while the user is actively typing, uncommitted input is discarded and restored to the previous committed value.
