Using my own answer for What is best approach to show the component page in popup-modal window without header and footer?, I mentioned that I was getting JS errors, so when as I further investigate, they persist:

TypeError:Argument 1 of Node.contains does not implement interface Node

Update: Turns out to be a Firefox issue, not Joomla, so pondering deleting the question pending resolution.

I put this lines directly into index.php of the Protostar template of a fresh default installation of Joomla 3.2.4 and tried it that way.

<a class='modal' href='index.php?option=com_content&view=article&tmpl=component&id=10&Itemid=180'>Modal link</a>

A small popup does appear, but contains nothing - has anyone dealt with this before? - I'm stumped.

  • what happens if you simply load an element in the modal rather than a component view...do you still get the same error?

  • Not sure what you mean or how to try it ... made the link go to google.com instead, and no error, but infinite spinner in the popup

  • Hmm ok, and what if you add &format=raw to the end of the URL?

  • The aha moment...I think it's Firebug, or at least in Firefox

  • I'll give this a test myself when I'm back from work if you still have issues

There is nothing wrong with your code. Try:

  • Turn on Joomla's Error Reporting and see if there is any error message

  • Disable Adblock if you have it

  • Open the link in a separate tab and see if it's valid (ie Joomla does not throw an error)

  • Use absolute URL instead of relative
