I have trolled the net + Stackoverflow and have not found an adequate answer to this question and before I start the trial and error process of finding my own solution, I thought I would turn to the Stackoverflow braintrust and see if there was already a successful implementation.
Specifically, I have an AJAX powered page that degrades properly for non-javascript browsers + 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
ReplyDeleteJust 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){}
});

This is the solution I ended up going with:

You're making this hard on yourself - just render a new iframe-based one.

This is how I handled this situation when I ran into it - seems to work well.
ReplyDelete// Set Facebook Like Button with jQuery
setFBLikeButtons = function (container,url,send,layout,width,show_faces,font) {
// Set Default Args
if(!send) { send = "false"; }
if(!layout) { layout = "button_count"; }
if(!width) { width = "100"; }
if(!show_faces) { show_faces = "false"; }
if(!font) { font = "arial"; }
$(container).empty(); // Remove current like button
$(container).html('<fb:like href="'+url+'" send="'+send+'" layout="'+layout+'" width="'+width+'" show_faces="'+show_faces+'" font="'+font+'"></fb:like>');
FB.XFBML.parse(); // This is the magical syrup
}
Load it after the window loads, this is what works for me:
ReplyDelete$(window).load(function(){
$.getScript('http://connect.facebook.net/en_US/all.js', function() {
try{
FB.XFBML.parse();
} catch(ex) {}
});
});
create like button
