Passing parameters using an object has become a popular method among
jQuery add-ins. Few plugins actually validate the passed parameter
object to ensure that elements are spelled correctly.
Most plugins use the jQuery.extend method which would copy the passed
parameter { resiz: 1 } just as easily

I've added a jQuery .onClick to a form submit.
Is there a way to prevent the form from submitting?
The following form is used in several plug-ins...

})( oGlobalObject );
so variable abc is defined as a global object with properties and
methods..
Is the following form equivalent?

Is there a cross-browser jQuery plug-in that can preload several

I need to play an audio file in response to a user action. The player

Caching a jQuery object "globally" or any other way will help if the
object is:
- expensive to build, e.g., a large DOM, sprinkled with many objects
as was the case with my 250 questions
- reusable, e.g., a user can click to "hide all", "show all".
Instead of recalculating the object, I save

Any way to track where time is being spent in JavaScript?
Sam
When I expand my quiz to 250 questions, the jQuery scripts are timing
out. This happened once before and I was able to diagnose the problem
to a selector which wasn't precise. It was installing event handlers
on many elements, not the few necessary elements.
So here I am again, same symptom. I
if($(obj).attr('checked')) { // Hide the correct answers?
$('.quizsubheader').hide('slow');
} else {
$('.quizsubheader').show('slow');
};
What's the best one-liner method to achieve the same result above?
Sam
After hunting around, I ended up using a "window" icon, but I think
the expand / collapse or + / - would be better in retrospect.
I'm surprised there's no defacto standard emerging on icon
semantics... e.g., an "office" set, a "navagational" set...
Anyone know of any standards?
