How to detect DIV's dimension changed?

Question

I\'ve the following sample html, there is a DIV which has 100% width. It contains some elements. While performing windows re-sizing, the inner elements may be re-positioned,

Answer 1

You have to bind the resize event on the window object, not on a generic html element.

You could then use this:

$(window).resize(function() {
    ...
});

and within the callback function you can check the new width of your div calling

$('.a-selector').width();

So, the answer to your question is no, you can't bind the resize event to a div.
