Why Don't My Dynamically Added Facebook Social Plugins Appear?

Dynamic Facebook Social Plugin Visibility Issue

When integrating Facebook social plugins into a website, users have encountered difficulties when the plugin fails to appear after being added dynamically via JavaScript.

To address this issue, it is important to understand the initialization process of the Facebook JavaScript SDK. When initialized, the SDK scans the document for elements designated for parsing into social plugins. However, any content added subsequently will not be automatically recognized by the SDK.

To overcome this limitation, developers must manually invoke the FB.XFBML.parse() function. This function instructs the SDK to re-scan the document and locate any newly added elements designated for social plugins.

For example, if you dynamically add the following Facebook comments plugin:

<div class="fb-comments" data-href="http://website.com/z" data-width="700" data-numposts="7" data-colorscheme="light"></div>

To ensure its visibility, you would need to call:

FB.XFBML.parse();

By incorporating this step, the SDK will recognize the dynamically added content, allowing the social plugin to display as intended.
