javascript - Scrollbar appear / disappear event in jQuery?

Question

Is there a simple way in jQuery to detect when scrollbars appear and disappear on a div that has overflow:auto? (Like an event? Fingers crossed...)

(I'd prefer not to have to look at the height of the content of the div)

Answer 1

Another way to achieve this is to check whether there are scrollbars present using scrollLeft or scrollTop:

//nudge the scrollbar away from its starting position

$('#your_selector').scrollLeft(1);

//A value of 0 is assigned if the scrollbars are at their default position, 
//or are abscent

if($('#your_selector').scrollLeft() !== 0) return true;

//put the scrollbar back to its starting position

$('#your_selector').scrollLeft(0);
