I'm not sure I understand your approach, however, it seems like
getting it to work would mean calling $('#elem').enable and $
('#elem').disable, which are not $('#elem').removeAttr('disable'), $
('#elem').attr('disabled', ''), or $('#elem').attr('disabled', '') so
your approach is not transparent.
I can improve on my earlyer post as follows:
var superRemoveAttr = $.fn.removeAttr;
$.fn.removeAttr = function(name) {
if(name == 'disabled') {
this.each(function() {
return $(this).hasClass('buttonDisabled');
}).removeClass('buttonDisabled');
}
superRemoveAttr.call(this, name);
};
But again, I think there should be a better way without overwriting
the jQuery functions.
