I have trawled the net and Stack Overflow and have not found an adequate answer to this question. Before I start the trial and error process of finding my own solution, I thought I would turn to the Stack Overflow braintrust and see if there was already a successful implementation.

I have an AJAX powered page that degrades properly for non-javascript browsers and SEO. Each click in the AJAX version can be represented by a unique URL.

What I want to do is to dynamically change the HREF of the button. I do understand that this tag is converted to standard HTML at runtime (namely into a nasty table / iframe layout).

I was just wondering if anyone had any insight as to how to implement this FB like button onto AJAX powered pages?

Cheers in advance 🙂

EDIT:

What do you think of this method I just hacked together? See any huge problems with it?

    SIMPLE SOLUTION

    Just parse trigger the parse function when load complete.

    If you’re using jQuery, there’s a real easy and slick solution to this problem:

    $(document).ajaxComplete(function(){
    try{
        FB.XFBML.parse(); 
    }catch(ex){}
});
