Es5 getting started in EJ2 JavaScript Chat UI control

17 Dec 202414 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.

Dependencies

The list of dependencies required to use the Chat UI control in your application is given as follows:

|-- @syncfusion/ej2-interactive-chat
    |-- @syncfusion/ej2-base
    |-- @syncfusion/ej2-navigations
    |-- @syncfusion/ej2-inputs
    |-- @syncfusion/ej2-buttons
    |-- @syncfusion/ej2-popups

Control Initialization

The JavaScript (ES5) Chat UI control 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-interactive-chat\dist\global\ej2-interactive-chat.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-interactive-chat\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/popups/ej2-popups.min.js" type="text/javascript"></script>

            <script src="resources/lists/ej2-lists.min.js" type="text/javascript"></script>
            <script src="resources/dropdowns/ej2-dropdowns.min.js" type="text/javascript"></script>
            <script src="resources/navigations/ej2-navigations.min.js" type="text/javascript"></script>

            <!-- JavaScript (ES5) Chat UI control global script -->
            <script src="resources/interactive-chat/ej2-interactive-chat.min.js" type="text/javascript"></script>
       </head>
       <body>
       </body>
  </html>

Step 5: Now, add the Chat UI element and initiate the JavaScript (ES5) Chat UI control in the index.html by using following code

[src/index.html]

<!DOCTYPE html>
  <html xmlns="http://www.w3.org/1999/xhtml">
       <head>
          <title>JavaScript (ES5)</title>
          <!-- JavaScript (ES5) Chat UI 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/inputs/material.css" rel="stylesheet" type="text/css" />
          <link href="resources/navigations/material.css" rel="stylesheet" type="text/css" />
          <!-- JavaScript (ES5) Chat UI control style -->
          <link href="resources/interactive-chat/material.css" rel="stylesheet" type="text/css"/>

          <!-- JavaScript (ES5) Chat UI dependency global script -->
          <script src="resources/base/ej2-base.min.js" type="text/javascript"></script>
          <script src="resources/data/ej2-data.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>
          <script src="resources/inputs/ej2-inputs.min.js" type="text/javascript"></script>
          <script src="resources/lists/ej2-lists.min.js" type="text/javascript"></script>
          <script src="resources/dropdowns/ej2-dropdowns.min.js" type="text/javascript"></script>
          <script src="resources/navigations/ej2-navigations.min.js" type="text/javascript"></script>
          <!-- JavaScript (ES5) Chat UI control global script -->
          <script src="resources/interactive-chat/ej2-interactive-chat.min.js" type="text/javascript"></script>
       </head>
       <body>
            <!-- Add the HTML <div> chatui  -->
          <div class="chatui-container" style="height: 350px; width: 350px;">
            <div id="chatui"></div>
          </div>
          <script>
                // Initializes the Chat UI control
                let chatUI = new ej.interactivechat.ChatUI({});

                    // Render initialized Chat UI.
                chatUI.appendTo('#chatui');
          </script>
       </body>
  </html>

Step 6: Now, run the index.html in web browser, it will render the Syncfusion JavaScript (ES5) Chat UI control.

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

Step 2: The JavaScript (ES5) control’s global scripts and styles are already hosted in the below CDN link formats.

Syntax:

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

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

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

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

Example:

Script: https://cdn.syncfusion.com/ej2/ej2-interactive-chat/dist/global/ej2-interactive-chat.min.js

Styles: https://cdn.syncfusion.com/ej2/ej2-interactive-chat/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 Chat UI element and initiate the JavaScript (ES5) Chat UI control in the index.html by using following code.

ej.base.enableRipple(true);

// Initializes the Chat UI control
let chatUI = new ej.interactivechat.ChatUI({});

// Render initialized Chat UI.
chatUI.appendTo('#chatui');

    <div class="container" style="height: 380px; width: 450px;">
        <div id="chatui"></div>
    </div>
</body>
</html>

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

Configure messages and user

You can use the messages property to add messages and the user property to configure the current user for the chat.

ej.base.enableRipple(true);

let currentUserModel = {
    id: "user1",
    user: "Albert"
};

let michaleUserModel = {
    id: "user2",
    user: "Michale Suyama"
};

let chatMessages = [
    {
        author: currentUserModel,
        text: "Hi Michale, are we on track for the deadline?"
    },
    {
        author: michaleUserModel,
        text: "Yes, the design phase is complete."
    },
    {
        author: currentUserModel,
        text: "I’ll review it and send feedback by today."
    }
];

// Initializes the Chat UI control
let chatUI = new ej.interactivechat.ChatUI({
    messages: chatMessages,
    user: currentUserModel
});

// Render initialized Chat UI.
chatUI.appendTo('#default-chat');
