[jQuery] Re: Create a custom rule

[Jörn Zaefferer]

The first argument, "value", refers to the actual value-attribute. You'll
probably want to use the third argument, eg. "param":


$.validator.addMethod('hasClass', function(value, element, param) {
reurn $(element).hasClass(param); }, jQuery.format('Please check the
button'));


Also a bit simpler with a single return.
