Getting started with JavaScript (ES5) Color Picker control

23 Mar 2023 / 7 minutes to read

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-inputs\dist\global\ej2-inputs.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-inputs\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.

        <script src="resources/inputs/ej2-inputs.min.js" type="text/javascript"></script>
   </head>
   <body>
   </body>
  </html>

Step 5: Now, add the ColorPicker and initiate the Syncfusion JavaScript ColorPicker control in the index.html by using following code

[src/index.html]

<!DOCTYPE html>
  <html xmlns="http://www.w3.org/1999/xhtml">
   <head>
        <title>Essential JS 2</title>
        <!-- Essential JS 2 ColorPicker's dependency style -->
        <link href="resources/base/material.css" rel="stylesheet" type="text/css"/>
        <link href="resources/buttons/material.css" rel="stylesheet" type="text/css"/>
        <link href="resources/popups/material.css" rel="stylesheet" type="text/css"/>
        <link href="resources/splitbuttons/material.css" rel="stylesheet" type="text/css"/>

        <!-- Essential JS 2 ColorPicker's control style -->
        <link href="resources/inputs/material.css" rel="stylesheet" type="text/css"/>

        <!-- Essential JS 2 ColorPicker's dependency global script -->
        <script src="resources/base/ej2-base.min.js" type="text/javascript"></script>
        <script src="resources/buttons/ej2-buttons.min.js" type="text/javascript"></script>
        <script src="resources/popups/ej2-popups.min.js" type="text/javascript"></script>
        <script src="resources/splitbuttons/ej2-splitbuttons.min.js" type="text/javascript"></script>

        <!-- Essential JS 2 ColorPicker's control global script -->
        <script src="resources/inputs/ej2-inputs.min.js" type="text/javascript"></script>
   </head>
   <body>
        <!-- Add the HTML <input> element  -->
          <input type="color" id="element">
        <script>
            // initialize ColorPicker control
            var colorPicker = new ej.inputs.ColorPicker({}, "#element");
        </script>
   </body>
  </html>

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

Inline type

By default, the ColorPicker will be rendered using SplitButton and open the pop-up to access the ColorPicker. To render the ColorPicker container alone and to access it directly, render it as inline. It can be achieved by setting the inline property to true.

The following sample shows the inline type rendering of ColorPicker.

[src/index.html]

<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
        <title>Essential JS 2</title>
        <!-- Essential JS 2 ColorPicker's dependency style -->
        <link href="resources/base/material.css" rel="stylesheet" type="text/css"/>
        <link href="resources/buttons/material.css" rel="stylesheet" type="text/css"/>
        <link href="resources/popups/material.css" rel="stylesheet" type="text/css"/>
        <link href="resources/splitbuttons/material.css" rel="stylesheet" type="text/css"/>

        <!-- Essential JS 2 ColorPicker's control style -->
        <link href="resources/inputs/material.css" rel="stylesheet" type="text/css"/>

        <!-- Essential JS 2 ColorPicker's dependency global script -->
        <script src="resources/base/ej2-base.min.js" type="text/javascript"></script>
        <script src="resources/buttons/ej2-buttons.min.js" type="text/javascript"></script>
        <script src="resources/popups/ej2-popups.min.js" type="text/javascript"></script>
        <script src="resources/splitbuttons/ej2-splitbuttons.min.js" type="text/javascript"></script>

        <!-- Essential JS 2 ColorPicker's control global script -->
        <script src="resources/inputs/ej2-inputs.min.js" type="text/javascript"></script>
</head>
<body>
        <input type="file" id="fileupload" name="UploadFiles">
    <script>
        // initialize ColorPicker control
        var colorPicker = new ej.inputs.ColorPicker({
            //To render control as inline(flat).
            inline: true,
            showButtons: false
        }, "#element");
    </script>
</body>
</html>

The showButtons property is disabled in this sample because the control buttons are not needed for inline type. To know about the control buttons functionality, refer to the showButtons sample.

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

Step 2: The Essential JS 2 ColorPicker control’s scripts and style are added based on the CDN link formats.

Syntax:

Script: https://cdn.syncfusion.com/ej2/21.1.35/{PACKAGE_NAME}/dist/global/{PACKAGE_NAME}.min.js

Styles: https://cdn.syncfusion.com/ej2/21.1.35/{PACKAGE_NAME}/styles/material.css

Example:

Script: https://cdn.syncfusion.com/ej2/21.1.35/ej2-inputs/dist/global/ej2-inputs.min.js

Styles: https://cdn.syncfusion.com/ej2/21.1.35/ej2-inputs/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 ColorPicker element and initiate the Syncfusion JavaScript ColorPicker control in the index.html by using following code.

   <body>
<div id='container' style="margin:0 auto; width:300px;">
    <!--element which is going to render the ColorPicker-->
    <input type="color" id="element" />
</div>
</body>
<script>
//initialize ColorPicker.
var colorPicker = new ej.inputs.ColorPicker({}, "#element");
</script>
</html>

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