尝试通过AJAX-Methods验证客户端。

Answer 2

You may consider using the jQuery event.preventDefault() method.

 $('[id$="LinkButton1"]').click(function(event) {  
     if(! valdiateYourPage() ) {
         event.preventDefault();     
         // display validation errors or something
      }
      else {
           //proceed as normal
      }
  });

Put your page validation logic in the valdiateYourPage() javascript method. If it valdiates, then process as normal, if not then preventDefault() will stop any further event execution by your LinkButton.
