obtaining width & height of object AFTER it's been resized

obtaining width & height of object AFTER it's been resized

Hi!  I was wondering, on the following resize script, how can one find the after-resize width & height and put it in an alert? 

<style type="text/css"> #resizable { width: 150px; height: 150px; padding: 0.5em; } #resizable h3 { text-align: center; margin: 0; } </style> <script type="text/javascript"> $(function() { $("#resizable").resizable(); }); </script> <div class="demo"> <div id="resizable" class="ui-widget-content"> <h3 class="ui-widget-header">Resizable</h3> </div> </div><!-- End demo --> <div class="demo-description" style="display: none; "> <p>Enable any DOM element to be resizable. With the cursor grab the right or bottom border and drag to the desired width or height.</p> </div><!-- End demo-description -->
