Here is my working code that successfully displays the Facebook 'Feed' dialog in a new window:
<a class="fbShareToWall"
onClick='window.open("https://www.facebook.com/dialog/feed?app_id=103528099783xxx"
+ "&link=http://www.thesite.com"
+ "&name=Please%20respond%20to%20the%20link"
+ "&caption=Just%20work"
+ "&description=Comeon%20work"
+ "&redirect_uri=http://www.thesite.com");'">Share on Facebook</a>
This successfully displays the Feed dialog in a new window.
Notice the '&name' parameter in the code above -- on the Feed dialog it displays as: Please respond to the link.
BUT if you click on it -- it does nothing, as if it's not a link. But it is, in fact, a link.
The 'Please respond to the link' looks like a link -- it is in a bold font and the letters are blue, while the other params -- the 'caption' param which displays on the Feed dialog as 'Just Work', and the 'description' param which displays as 'Comeon work' -- those are not in a bold font nor are they in blue color. Just regular text, those two params.
So with my Feed dialog box open, I right-clicked on the Please respond to the link and selected 'Open link in a new window' and Firefox opens a new browser and the URL bar has the http://www.thesite.com which, as you notice, is how I set my &link parameter in the above code. In other words -- Firefox has no problem navigating with the URL connected to my &name parameter.
Next, I checked and made sure Firefox was not blocking popups. It wasn't.
I don't undersand why my "Please respond to the link" feed dialog &name parameter:
looks like a clickable link on the Feed Dialog box
and upon being right-clicked, it can be opened in a new browser -- and navigates to the &link parameter successfully
and yet does NOT do anything if you click on Please respond to the link on the Feed dialog.
Am I missing something in my Feed dialog code above?
What is the purpose of the &name parameter on that Feed dialog box?
Or what's the point of having the &link and &name paramaters appear to be a link on the Feed dialog but then NOT work when clicked on?
