I use jQueryUI tooltip for validation.

I just want exactly do this: when Textbox focusout or sumbit button click empty textbox tooltip appear. I write this script but this script have this problem:

1. on click or Mouseover or Mouseout ... in Textbox the tooltip does not appear.just on focusout or sumbit button tootltip mus appear.how can i do that? after tooltip shows on mouse over tooltip disappear. how can i prevent that???

2. tooltip not disappear just disappear when user click in Textbox .how can i do that?
