Step 1: Load the Facebook SDK for JavaScript
The Facebook SDK for JavaScript enables you to use various Facebook features on your web page, such as authentication, social plugins, analytics, and more. To load the SDK, you need to add a div element with an id of fb-root and a script element that points to the SDK source URL. You also need to specify your Facebook app ID and the Graph API version that you want to use. For example:
<div id="fb-root"></div> <script async defer crossorigin="anonymous" src="https://connect.facebook.net/en_US/sdk.js#version=v12.0&appId=1234567890"></script>
You can create a Facebook app ID by following the instructions [here]. The latest Graph API version is v12.0, but you can check the available versions [here].
Step 2: Use the Like Button Configurator
The Like Button Configurator is a tool that helps you generate the code for your custom Like button. You can access it [here]. To use it, you need to enter the URL of your iFrame tab app content that you want users to like. For example, if your app content is hosted at https://www.example.com/my-app.html, then you need to enter that URL in the configurator. You can also customize the appearance of your Like button by choosing the layout, size, action type, and whether to include a Share button or not. For example, you can choose a standard layout, a small size, a like action type, and a Share button. After you have made your choices, click on the Get Code button and copy the code that appears in the popup window.
Step 3: Paste the Code into Your iFrame Tab App Content
The code that you copied from the configurator consists of two parts: a div element with a class of fb-like and some attributes that specify your Like button options, and a script element that initializes the SDK. You need to paste both parts into your iFrame tab app content HTML file, preferably near the end of the body tag. For example:
<!-- Your iFrame tab app content --> <div data-href="https://www.example.com/my-app.html" data-width="" data-layout="standard" data-action="like" data-size="small" data-share="true"></div> <script> window.fbAsyncInit = function() FB.init( appId : '1234567890', xfbml : true, version : 'v12.0' ); ; </script> <!-- Load the SDK --> <div id="fb-root"></div> <script async defer crossorigin="anonymous" src="https://connect.facebook.net/en_US/sdk.js#version=v12.0&appId=1234567890"></script> </body> </html>
Make sure that you replace the app ID and the URL with your own values. Also, note that the data-href attribute of the div element and the URL parameter of the SDK source should match exactly.
