jQuery.support fails in iframe

[Krinkle]

The test suite for jQuery.support has been failing for a looong time in the TestSwarm. From my rough estimates I think my jquery-swarm vm spends over 30% of the time re-testing jQuery.support).

Not a single browser that is in the swarm returns something at all for that module. (they all time-out or throw exceptions). This can be seen here:  http://swarm.jquery.org/job/1238/

It fails everywhere.

However when running it standalone, such as from here:  http://swarm.jquery.org/git/jquery/39c6c85/test/index.html?filter=support ... then it works fine.

Steps to reproduce

• Go to a random page with jQuery on it (say, the last url linked above)
• Open up the console and execute:

  jQuery('body').html( '<iframe src="http://swarm.jquery.org/git/jquery/39c6c85/test/index.html?filter=support" width="100%" height="100%">' );
  

• Result:

  TypeError: Result of expression 'window.top.supportCallback' [undefined] is not a function.

I'm not sure what's going on there, but it doesn't seem like a jQuery core problem.

QUnit tests are part of jQuery's core repository. A failing test means either the test needs fixing or the unit being tested does.

I think the unit being tested is failing. Try preforming the jQuery actions in support from within an iframe. It's incorrectly accessing windows, assuming the rootjQuery is in the top window.

I can confirm this problem. It makes it impossible to run the JQuery tests in TestSwarm. Why is this marked as invalid?

Now confirmed with  test case

This above link runs your local jQuery test suite, adjust the address as needed.

Not sure jsFiddle allows echo/html through GET (I couldn't get it to work).

Here's a test case off jsFiddle:  http://toolserver.org/~krinkle/tmp/jqbug-9555-frame/

Steps to reproduce:

• check out fresh github-jquery-jquery-master
• include github-jquery-qunit as well in /test/qunit
• Create a new .html page only containing an iframe pointing to jquery/test/index.html?filter=support

Confirmed. "Uncaught TypeError: Object [object DOMWindow] has no method 'supportCallback'"
