UI dialog widget

UI dialog widget

Is it possible to make maintaining aspect ratio on resizing? if yes, how?
I tried to set in this way:
  1. <div id="dial01" title="NAME">CONTENT</div>
  2. <script>
  3. $( "#dial01" ).dialog({modal:true, minHeight:100});
  4. $("div[aria-describedby='dial01']").resizable({aspectRatio:true});
  5. </script>
However, no debug mistake and no result in maintaining aspect ratio.
