I'm trying to display a jquery-ui tooltip when validation detects form errors. I can make it happen using the following code, but the effect is that a new tooltip gets created each time validation fails. Any idea how I can either tell ui-tooltip to reuse the existing tooltip OR tell validate to clean up the old tooltip first?

1. $('form').validate({
2.   errorPlacement: function(error, placement) {
3.     var text = error.text();
4.     placement.tooltip({
5.       content: function(){ return text; }
6.     }).tooltip('open');
7.   }
8. });

Also, any general tips or improvement suggestions welcomed.
