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

Only Window.onResize exists in the specification, but you can always utilize IFrame to generate new Window object inside your DIV.

Please check this answer. There is a new little jquery plugin, that is portable and easy to use. You can always check the source code to see how it's done.

// (2) use the detectResizing plugin to monitor changes to the element's size:
$monitoredElement.detectResizing({ onResize: monitoredElement_onResize });

// (3) write a function to react on changes:
function monitoredElement_onResize() {    
    // logic here...
}
