jQuery-1.9.1 removeClass() not working properly

[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;

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

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().

[dguzzo@…]

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(...
