jQuery variable element syntax

Question

I use the same element in my function several times. For example:

var myElement = jQuery('#some_div_with_good_id');
var myChildren = jQuery('#some_div_with_good_id span');

So how I can optimize this code for shorten second variable? I tried:

var myChildren = jQuery(myElement, 'span');

but this not works :( I'm new in jQuery, so sorry if you think it is stupid question.

var myChildren = myElement.find('span');

It's the other way around -> jQuery('span', myElement);

Try it the other way, jQuery('span', myElement) should work.

var children = $( element ).children( 'span' );

That's not equivalent to jQuery('#some_div_with_good_id span'), which finds descendant spans at all levels; .children() just finds immediate children.

Ah. Going by his variable name (myChildren), I figured he only wanted the children of that element.
