Test for empty jQuery selection result
- by fsb
Say I do
var s = $('#something');
and next I want to test if jQuery found #something, i.e. I want to test if s is empty.
I could use my trusty isempty() on it:
function isempty(o) {
for ( var i in o )
return false;
return true;
}
Or since jQuery objects are arrays, I suppose I could test s.length.
But neither seem quite in the idiom of jQuery, not very jQueryesque. What do you suggest?
