Jquery balloons

Jquery balloons

I would like to replace the #voip in URL parameter of this code with the variable ID.

any thoughts?

$(function{
$('.DDD').mouseover(function() {
    var ID = (this.id);
     alert (ID);
       });
   
$('.DDD').balloon({
      classname:"DTT",   
      position: 'right',
      url: '/idirectSlider.html #voip'   // replace #voip with ID variable here.
         
    });     
});


***HTML*****

<span class="DDD" title=" " id="voip"> VoIP</span>

I can mot seem to make it work.
