    <p>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.</p> <p>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. </p> <p>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).</p> <p>I was just wondering if anyone had any insight as to how to implement this FB like button onto AJAX powered pages?</p> <p>Cheers in advance :)</p> <p><strong>EDIT:</strong></p> <p>What do you think of this method I just hacked together? See any huge problems with it?</p> <pre><code>&lt;!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"&gt; &lt;html xmlns="http://www.w3.org/1999/xhtml"&gt; &lt;head runat="server"&gt; &lt;title&gt;&lt;/title&gt; &lt;script src="JS/jquery/jquery.js" type="text/javascript"&gt;&lt;/script&gt; &lt;script src="http://connect.facebook.net/en_US/all.js#xfbml=1"&gt;&lt;/script&gt; &lt;script language="javascript" type="text/javascript"&gt; $("document").ready ( function () { CreateNewLikeButton("http://www.yahoo.com") $("a#ChangeToGoogle").click ( function (e) { e.preventDefault(); CreateNewLikeButton("http://www.google.ca") } ); } ); function CreateNewLikeButton(url) { var elem = $(document.createElement("fb:like")); elem.attr("href", url); $("div#Container").empty().append(elem); FB.XFBML.parse($("div#Container").get(0)); } &lt;/script&gt; &lt;/head&gt; &lt;body&gt; &lt;form id="form1" runat="server"&gt; &lt;a id="ChangeToGoogle" href="#"&gt;Change To Google&lt;/a&gt; &lt;div id="Container"&gt; &lt;fb:like href="http://www.NEVER_LINK_TO_THIS_12345.com"&gt;&lt;/fb:like&gt; &lt;/div&gt; &lt;/form&gt; &lt;/body&gt; &lt;/html&gt; </code></pre>

    1. COAre you saying you're using XFBML version of the like button? Why not just use the iframe one?

    2. COIt just seems cumbersome to have to parse the DOM of that to dynamically change the HREF of the button. I just wanted to see if there was a way to change it using XFBML.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
