jquery resize listener on a div

Question

This is the situation, I have 2 div\'s next to each other. One div is very dynamic in height, which basically means it can grow and shrink to accommodate for it\'s content.

Answer 1

The only thing I could think of is having some timer checking the height every X seconds.

Something like this:

function checkHeightTimer(){
    var div1 = $('#div1');
    var div2 = $('#div2');
    var somesize = #somenumber here;
    if(div1.height() > somesize){
        //do something to div2
    }
    setTimeout(checkHeightTimer, 500); //at 500 miliseconds
}
