How to turn 'this' into a jquery object?

How to turn 'this' into a jquery object?

How do you turn 'this' into a jQuery object so that you can invoke jQuery methods on it?
For example I have this code currently:

<tr onmouseover="this.className='highlight';" onmouseout="this.className='';">


But I would like to use jQuery's addClass and removeClass function. So Ive tried things like:

this.addClass('highlight');


,which doesnt work I assume because this is not yet a jQuery wrapped-object

and
$('this').addClass('highlight');


, which doesnt work because I guess its like calling document.getElementById('this') which is crazy.

So how do you do it? thanks![/code]
