Why Are My Dynamically Injected Facebook Social Plug-ins Hidden?

Dynamic Injection of Facebook Social Plug-in Encountering Visibility Issues

Adding social plug-ins from Facebook enhances the interactivity of web pages. However, issues can arise when attempting to dynamically inject such plug-ins using JavaScript code.

One such issue encountered when adding Facebook social plug-ins is that they remain hidden despite being added to the page. This occurs when the plug-in is manually added to the DOM, but not when dynamically added using JavaScript.

Addressing the Problem:

To resolve this issue, it is necessary to call the FB.XFBML.parse() function. This function allows the JavaScript SDK to re-parse the DOM for any additional social plug-ins that have been dynamically added.

The code below demonstrates how to use FB.XFBML.parse():

<code class="javascript">FB.XFBML.parse();</code>

By calling this function after dynamically adding the Facebook social plug-in, the SDK will recognize the new plug-in and render it accordingly.

Additional Information:

The Facebook JavaScript SDK scans the DOM once upon initialization to identify and parse any existing social plug-in elements. However, for dynamically added content, this re-parsing step is required to ensure that the newly added plug-in is recognized and displayed correctly.
