Disabled attribute of input elements

[[email protected]…]

When you want to enable a disabled element with $(element).set('disabled', false), it fails.

In $.attr, "o[a] = v" does the job but "o.setAttribute(a,v)" reverts disabled to true.

• Failure only with FF (works fine with IE) on WinXP.

• Test case: ​http://fmarcia.info/jquery/disabled

• Workaround: use $(element).get(0).disabled = false (or each() if several elements are involved)

Thanks for the find, Frack - this has been fixed in SVN rev [81].

Maybe I misunderstand what was trying to be conveyed, but using his example with the current version of jQuery (1.1.3.1) is still broken with Firefox 2.0.0.4 on XP. So, the first two sets of buttons do not work, while the third set (his workaround) works. Also, you could add the following to his example as workarounds that work:

<input type="button" value="Disable" onclick="$('#x').attr('disabled','disabled')"/>
<input type="button" value="Enable" onclick="$('#x').attr('disabled','')"/>

IE7 gives error when disabling a drop down list. $('select#country').attr('disabled', true); or $('select#country').attr('disabled', 'disabled');
