Two versions of jQuery and the $.noConflict causes some weird behavior on link clicks

I created a sample here:

The problem is, when I call .click() on a link with the noconflicted version of jquery, the previously attached event doesn't run (.trigger('click') doesn't work either).

If I do the same with a button, then the counter increases (in the example).

I did some digging, and this is the line, where everything stops:

What is the expected behavior?

This is expected behavior. Updated test case:

Each copy of jQuery has its own event list. When you manually .trigger("click") or .click() the copy of jQuery does most of the work. It has to:

  • Start at the event target (the innermost element clicked)
  • Run any associated event handlers that **this copy of jQuery** knows about; it doesn't know about lists held by other copies but it does know about the inline onclick handlers.
  • Bubble up the DOM repeating the process until it reaches window.
  • For all DOM methods **except click**, run the DOM method if the default action has not been stopped with event.preventDefault(). See #12652 for why this exception exists.

If you need to bridge two copies of jQuery you could a click handler on one copy that triggered a similar click on the other jQuery copy. Really though, two copies of jQuery in a page should be avoided.

I saw the other ticket, but this really seems inconsistent to me, because it works with other elements, but not with links.

And it is sad, but I don't really have any knowledge about the other jQuery versions. I mean, I could write some

if (!jQuery) { doc.write('<script src="own-jquery.js"></scr'+'ipt>'); }

code but it seemed a bad idea. And then I have to put up with all the old versions of jQuery's quirks, not to mention if for some reason they use $.noConflict too, when attaching event listeners, than there is no way of triggering a click event, that runs all the handlers that were attached is any way. At least not with jQuery. This is so sad.

But, thank you really!
