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

Dependencies

  • ej2-base

  • 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-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 TimePicker Component</title>
    <!-- Essential JS 2 TimePicker's dependent material theme -->
    <link href="//cdn.syncfusion.com/ej2/ej2-base/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 TimePicker'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 TimePicker component in the index.html by using following code

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

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

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

</html>

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

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 TimePicker'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 TimePicker'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 TimePicker component
        var timeObj = new ej.calendars.TimePicker();
        // Render initialized Timepicker.
        timeObj.appendTo('#element')
    </script>
</body>

</html>

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

Setting the time format

Time formats is a way of representing the time value in different string format in textbox and popup list. By default, the TimePicker’s format is based on the culture. You can also customize the format by using the format property. To know more about the time format standards, refer to the Date and Time Format section.

The following example demonstrates the TimePicker component in 24 hours format with 60 minutes interval. The time interval is set to 60 minutes by using the step property.

Preview
index.js
index.html
ej.base.enableRipple(true);
   
    var timepicker = new ej.calendars.TimePicker({
        placeholder: 'Select a time',
            value: new Date(),
    // sets the format property to display the time value in 24 hours format.
    format: 'HH:mm',
    // specify the interval value.
    step: 60
    });    
    timepicker.appendTo('#element');

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


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

Once the time format property is defined, it will be applicable to all the cultures.
