670528 - FF5+: [link].click no longer returns undefined, though [link].click() still unsupported.

Status: VERIFIED FIXED

(Core :: DOM: Core & HTML, defect)

Description

[pete.j.scott]

Attachment: index.html

User Agent: Mozilla/5.0 (X11; Linux i686; rv:6.0) Gecko/20100101 Firefox/6.0
Build ID: 20110705195857

Steps to reproduce:

Tested code to avoid firing click() on an anchor element by checking for (anchor.click), 
i.e.:
if (anchor.click) { anchor.click(); }

[ATTACHED AS index.html].


Actual results:

anchor.click returns a function in Firefox 5.0 and Firefox 6.0. Previously (FF3.6, FF4.0) it returned 'undefined'. This causes existing code that allows anchor.click() calls when anchor.click != 'undefined' to fire, which does not work (and does not throw error, simply fails to execute).


Expected results:

I would expect anchor.click to continue returning 'undefined', since anchor.click() is still not supported by Firefox.

This should be fixed with bug 666604 in Firefox 7.

Please download and test with Firefox 7 Aurora build, thanks!

Note that anchor.click() does in fact execute and does what it's supposed to: fires an untrusted click event on the anchor.  If you have an onclick listener, it will get triggered....
