Please provide a test case in jsFiddle. Sounds like something is shimming .removeClass() improperly, if there are NO arguments then arguments.length===0.

Replying to [ticket:13531 adam.levitt@…]:

On line 2114, there is a bug for calling .removeClass() with no parameters. This check fails:

> proceed = arguments.length === 0 || typeof value === "string" && value;
> 

It fails because there is actually a single argument being passed in which is "undefined". Here was my fix:

> proceed = arguments[0] === undefined || arguments.length === 0 || typeof value === "string" && value;
> 

Here's the snippet of code in jquery.validate.password.js that's causing this issue:

var meter = $(".password-meter", element.form);
		
		meter.find(".password-meter-bar").removeClass().addClass("password-meter-bar").addClass("password-meter-" + rating.messageKey);
		meter.find(".password-meter-message")
		.removeClass()
		.addClass("password-meter-message")
		.addClass("password-meter-message-" + rating.messageKey)
		.text($.validator.passwordRating.messages[rating.messageKey]);

I can't run that snippet to see what .removeClass() does. Make a jsFiddle and remove all plugins, then see what .removeClass() does. If it works then some code outside jQuery is breaking .removeClass().

jQueryUI extends .removeClass() to accept

speed, easing

, and

callback

arguments. if those are provided, it calls the original jQuery definition of the function with

classNames

, which is undefined. this breaks expected behavior as Adam describes in the bug report.

(to see it work as it should, uncheck the "jQuery UI 1.9.2" checkbox and re-run. bam.

yep, definitely should be fixed on the UI end (good to hear it has been—time for me to upgrade!)

:)

if you cant upgrade to 1.10.1 quite yet, this worked for me...

.removeClass().addClass(...

to

.attr("class","").addClass(...
