"live" / "delegate" bug about ":enabled" filter

Reported by: Owned by:
Priority: undecided Milestone: None
Component: unfiled Version: 1.8.0
Keywords: Cc:
Blocked by: Blocking:

If we use "live" or "delegate" to attach an event handler (for example about an ajax panel) and if we use one of related selectors or methods to filter ":enabled" elements and if the result of selector represents to a collection of anchors(link tags) and input buttons or other type of inputs then : "that event handler doesn't work just for links(anchors) and the just reason is checking for :enabled on anchors because anchors doesn't have the ability for enabling or disabling"

so finally BOOOM

$('[rel*="AjaxElement"]:enabled').live('click', function(e){}) //inputs ok, anchors boom

jQuery version : accident(1.7.1) - test again and bug again(1.8.0)

OS : win7

First accident code : $('[rel*="Async"]:not(:text, :password, select, textarea):not([rel*="NotAsync"])').not('[disabled]').live('click', fun...

Debug reduced codes : yes :

alert($('#Nav a').filter('enabled').live('click', fun).length); //13 number of results and fun wasn't triggered

WARNING ! be careful through .click and .live('click' because click works correctly and the problem is .live

Thanks for taking the time to contribute to the jQuery project! Please provide a complete reduced test case on jsFiddle to help us assess your ticket.

Additionally, be sure to test against the jQuery Edge version to ensure the issue still exists. To get you started, use this boilerplate: Open the link and click to "Fork" (in the top menu) to get started.

The .live method cannot be used in a chain like that, see the documentation. Also, .live is deprecated.

With regard to jQuery Documentation(:enabled) on describing : ".... In other words, the bare $(':enabled') is equivalent to $('*:enabled'), so $('input:enabled') should be used instead. .... "

But in fact the subject is different. Let's take a look:

OK there is no problem with .live because the actual bug is from :enabled selector returning different result against :not(:disabled)

As described in documentation :enabled should be like *:enabled NOT input:enabled

Please check the fiddle code :
