Avoid attr(), and try to avoid fitting every problem into a jQuery
solution...

Try this simple code:

$(':checkbox.chkEvent').each(function() {
  this.checked = !this.checked;
}

I also keep my "run" plugin handy for simple things like this:

// A General "run" function to simplify coding
$.fn.run = function(fn) {
        if (typeof fn=='string') { fn = new Function(fn); }
        this.each(fn);
}

Then:

$(':checkbox.chkEvent').run("this.checked = !this.checked");

Whether that's actually more efficient to write depends on the
situation ;)
