title: does jquery .post or ui dialog have a "please wait . ." icon option?
body: <p>when i click on a link, i have a jquery .post call in a javascript function.  This calls a controller action which returns a partialresult into a jquery ui dialog.</p>
  
  <p>this process can take a few seconds as the controller calls the model for some calculations, etc . .</p>
  
  <p>anyway, is there anyway to display a "Please wait . ." or animated icon from the time after the link is clicked up until the dialog is displayed ?</p>
