Getting Started with JavaScript(ES5)

The Essential JS 2 for JavaScript (global script) is an ES5 formatted pure JavaScript framework which can be directly used in latest web browsers.

Component Initialization

Create an app folder myapp in local machine to initialize Essential JS 2 JavaScript components.

Using either of the following way to refer the required script and styles.

Using local script and style references in a HTML page.
Using CDN link for script and style reference.

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 DateTimePicker component, need to add DateTimePicker and its dependent packages from below installed location.

Dependencies

ej2-base
ej2-buttons
ej2-inputs
ej2-popups
ej2-lists
ej2-calendars

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-base

packages: C:/Program Files (x86)/Syncfusion/Essential Studio/15.4.30/Essential JS 2/ej2-buttons

packages: C:/Program Files (x86)/Syncfusion/Essential Studio/15.4.30/Essential JS 2/ej2-inputs

packages: C:/Program Files (x86)/Syncfusion/Essential Studio/15.4.30/Essential JS 2/ej2-popups

packages: C:/Program Files (x86)/Syncfusion/Essential Studio/15.4.30/Essential JS 2/ej2-lists

Package: C:/Program Files (x86)/Syncfusion/Essential Studio/15.4.30/Essential JS 2/ej2-calendars

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 Essentials JS 2 script and style references.

<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
    <title>Essential JS 2 DateTimePicker Component</title>
    <!-- Essential JS 2 DateTimePicker'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 DateTimePicker'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>
</body>

</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 DateTimePicker component in the index.html by using following code

<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">

<head>
    <title>Essential JS 2 DateTimePicker Component</title>
    <!-- Essential JS 2 DateTimePicker'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 DateTimePicker'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 DateTimePicker component
        var DateTimePicker = new ej.calendars.DateTimePicker();

        // Render initialized DateTimePicker.
        DateTimePicker.appendTo('#element')
    </script>
</body>

</html>

Step 6: Now, run the index.html in web browser, it will render the Essential JS 2 DateTimePicker 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.js

Style: http://cdn.syncfusion.com/ej2/{PACKAGE_NAME}/styles/material.css

Example:

Script: http://cdn.syncfusion.com/ej2/ej2-calendars/dist/global/ej2-calendars.min.js

Styles: http://cdn.syncfusion.com/ej2/ej2-calendars/styles/material.css

Step 2: Have to add CDN global script and style for calender and its dependent packages in myapp/index.html like below.

<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">

<head>
    <title>Essential JS 2 Calendar Component</title>
    <!-- Essential JS 2 DateTimePicker'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 DateTimePicker'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 button component
        var DatetimeObj = new ej.calendars.DateTimePicker();
        // Render initialized button.
        DatetimeObj.appendTo('#element')
    </script>
</body>

</html>

When referencing CDN links in application, always ensure the network connection will be in enabled state.

Setting the min and max

The minimum and maximum date time can be defined with the help of min and max property. The following example demonstrates to set the min and max on initializing the DateTimePicker.

Preview

index.js

index.html

var month = new Date().getMonth();
  var fullYear = new Date().getFullYear();

      var datetimepicker = new ej.calendars.DateTimePicker({
        // Sets the min.
    min: new Date(fullYear, month , 22, 12),
    //Sets the max.
    max: new Date(fullYear, month, 25, 17),
    });
    datetimepicker.appendTo('#element');

</head>

<body>
    
    <div id="container">
        <input id="element" type="text">
    </div>


<script>
var ele = document.getElementById('container');
if(ele) {
    ele.style.visibility = "visible";
 }   
        </script>
<script src="index.js" type="text/javascript"></script>
</body></html>

If the value of min or max properties changed through code behind, then you have to update the value property to set within the range.
