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.

Control Initialization

The Essential JS 2 JavaScript controls can be initialized by using either of the following ways.

  • 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: Create an app folder quickstart for getting started.

Step 2: You can get the global scripts and styles from the Essential Studio JavaScript (Essential JS 2) build installed location.

Syntax:

Dependency Script: **(installed location)**\Syncfusion\Essential Studio\JavaScript - EJ2\{RELEASE_VERSION}\Web (Essential JS 2)\JavaScript\{DEPENDENCY_PACKAGE_NAME}\dist\global\{DEPENDENCY_PACKAGE_NAME}.min.js

Control Script: **(installed location)**\Syncfusion\Essential Studio\JavaScript - EJ2\{RELEASE_VERSION}\Web (Essential JS 2)\JavaScript\{PACKAGE_NAME}\dist\global\{PACKAGE_NAME}.min.js

Dependency Styles: **(installed location)**\Syncfusion\Essential Studio\JavaScript - EJ2\{RELEASE_VERSION}\Web (Essential JS 2)\JavaScript\{DEPENDENCY_PACKAGE_NAME}\styles\material.css

Control Styles: **(installed location)**\Syncfusion\Essential Studio\JavaScript - EJ2\{RELEASE_VERSION}\Web (Essential JS 2)\JavaScript\{PACKAGE_NAME}\styles\material.css

Example:

Dependency Script: C:\Program Files (x86)\Syncfusion\Essential Studio\JavaScript - EJ2\16.3.0.17\Web (Essential JS 2)\JavaScript\ej2-base\dist\global\ej2-base.min.js

Control Script: C:\Program Files (x86)\Syncfusion\Essential Studio\JavaScript - EJ2\16.3.0.17\Web (Essential JS 2)\JavaScript\ej2-buttons\dist\global\ej2-buttons.min.js

Dependency Styles: C:\Program Files (x86)\Syncfusion\Essential Studio\JavaScript - EJ2\16.3.0.17\Web (Essential JS 2)\JavaScript\ej2-base\styles\material.css

Control Styles: C:\Program Files (x86)\Syncfusion\Essential Studio\JavaScript - EJ2\16.3.0.17\Web (Essential JS 2)\JavaScript\ej2-buttons\styles\material.css

The below located script and style file contains all Syncfusion JavaScript (ES5) UI control resources in a single file.

Scripts: **(installed location)**\Syncfusion\Essential Studio\JavaScript - EJ2\{RELEASE_VERSION}\Web (Essential JS 2)\JavaScript\ej2\dist\ej2.min.js

Styles: **(installed location)**\Syncfusion\Essential Studio\JavaScript - EJ2\{RELEASE_VERSION}\Web (Essential JS 2)\JavaScript\ej2\material.css

The Custom Resource Generator (CRG) is an online web tool, which can be used to generate the custom script and styles for a set of specific controls. This web tool is useful to combine the required control scripts and styles in a single file.

Step 3: Create a folder ~/quickstart/resources and copy/paste the global scripts and styles from the above installed location to ~/quickstart/resources/package corresponding package location.

Step 4: Create a HTML page (index.html) in ~/quickstart/index.html 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</title>
        <!-- Essential JS 2 Base's material theme (Dependency Styles) -->
        <link href="resources/base/material.css" rel="stylesheet" type="text/css"/>
        <!-- Essential JS 2 CheckBox's material theme (Control Styles) -->
        <link href="resources/buttons/material.css" rel="stylesheet" type="text/css"/>

        <!-- Essential JS 2 Base's global script (Dependency Script) -->
        <script src="resources/base/ej2-base.min.js" type="text/javascript"></script>
        <!-- Essential JS 2 CheckBox's global script (Control Script) -->
        <script src="resources/buttons/ej2-buttons.min.js" type="text/javascript"></script>
    </head>
    <body>
    </body>
</html>

Step 5: Now, add the CheckBox element and initiate the Syncfusion JavaScript (ES5) CheckBox controls in the ~/quickstart/index.html by using following code

<!DOCTYPE html>
  <html xmlns="http://www.w3.org/1999/xhtml">
      <head>
          <title>Essential JS 2</title>
          <!-- Essential JS 2 Base's material theme (Dependency Styles) -->
          <link href="resources/base/material.css" rel="stylesheet" type="text/css"/>
          <!-- Essential JS 2 CheckBox's material theme (Control Styles) -->
          <link href="resources/buttons/material.css" rel="stylesheet" type="text/css"/>

          <!-- Essential JS 2 Base's global script (Dependency Script) -->
          <script src="resources/base/ej2-base.min.js" type="text/javascript"></script>
          <!-- Essential JS 2 CheckBox's global script (Control Script) -->
          <script src="resources/buttons/ej2-buttons.min.js" type="text/javascript"></script>
      </head>
       <body>
            <!--element which is going to render-->
            <input id="element" type="checkbox"/>
            <script>
                // Initialize CheckBox control.
                var checkbox = new ej.buttons.CheckBox({ label: 'Default' });

                // Render initialized CheckBox.
                checkbox.appendTo('#element');
            </script>
       </body>
  </html>

Step 6: Now, run the index.html in web browser, it will render the Syncfusion JavaScript CheckBox control.

Step 1: Create an app folder quickstart for getting started.

Step 2: The Essential JS 2 control’s global scripts and styles are already hosted in the below CDN link formats.

Syntax:

Dependency Script: http://cdn.syncfusion.com/ej2/{DEPENDENCY_PACKAGE_NAME}/dist/global/{PACKAGE_NAME}.min.js

Control Script: http://cdn.syncfusion.com/ej2/{PACKAGE_NAME}/dist/global/{PACKAGE_NAME}.min.js

Dependency Styles: http://cdn.syncfusion.com/ej2/{DEPENDENCY_PACKAGE_NAME}/styles/material.css

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

Example:

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

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

Step 3: Create a HTML page (index.html) in ~/quickstart/index.html location and add the CDN link references. Now, add the CheckBox element and initiate the Syncfusion JavaScript CheckBox control in the index.html by using following code.

            <input id="element" type="checkbox"/>
            <script>
                ej.base.enableRipple(true);

                // Initialize CheckBox control.
                var checkbox = new ej.buttons.CheckBox({ label: 'Default' });

                // Render initialized CheckBox.
                checkbox.appendTo('#element');
            </script>
       </body>
  </html>
#container {
    visibility: hidden;
}

#loader {
  color: #008cff;
  height: 40px;
  width: 30%;
  position: absolute;
  top: 45%;
  left: 45%;
}

li {
  list-style: none;
}

.e-checkbox-wrapper {
  margin-top: 18px;
}

.e-checkicon.e-checkbox-wrapper .e-frame.e-check::before {
    content: '\e790';
}

.e-checkicon.e-checkbox-wrapper .e-check {
    font-size: 8px;
}

.e-checkicon.e-checkbox-wrapper .e-frame.e-check {
    background-color: white;
    border-color: grey;
    color: grey;
}

.e-checkicon.e-checkbox-wrapper:hover .e-frame.e-check {
    background-color: white;
    border-color: grey;
    color: grey;
}

.e-checkicon.e-checkbox-wrapper .e-checkbox:focus + .e-frame.e-check {
    background-color: white;
    border-color: grey;
    box-shadow: none;
    color: grey;
}

.e-checkicon.e-checkbox-wrapper .e-ripple-element {
    background: grey;
}

Step 4: Now, run the index.html in web browser, it will render the Syncfusion JavaScript CheckBox control.

Change the CheckBox state

The Essential JS 2 CheckBox contains 3 different states visually, they are:

  • Checked
  • Unchecked
  • Indeterminate

The CheckBox checked property is used to handle the checked and unchecked state. In checked state a tick mark will be added to the visualization of CheckBox.

Indeterminate

The CheckBox indeterminate state can be set through indeterminate property. CheckBox indeterminate state masks the real value of CheckBox visually. The Checkbox cannot be changed to indeterminate state through the user interface, this state can be achieved only through the property.
