jQuery Forum

I like that idea. 

We could do this fairly easily, but it may be too late for feature requests for 1.6.  I am always concerned about adding size to jQuery, but I like the idea.

+1 for this idea, while working on a web app I wanted to toggle the contenteditable boolean. Obviously a simple if/else statement works, but toggle("contenteditable") would even be better for boolean attributes, and the above mentioned solution would even work for non-boolean attributes.

What about to just receive one parameter
It's working with checked, disabled and readonly...

$.fn.extend({
  toggleAttr : function( attrib ) {
    if ( this.attr( attrib ) ) {
      this.removeAttr( attrib );
    } else {
      this.attr( attrib, attrib );
    }

I too could have really used this feature for adding disabled and the like to classes. If toggleClass is in jQuery then so too should this function be.

Just use prop:

1. function onclick() {      
2.        $('#myselector').prop('checked', expression);
3. }
