                theForm.__EVENTTARGET.value = eventTarget; 
                theFrom.__EVENTARGUMENT.value = eventArgument; 

theForm.submit(); 
             } 
             --> 
             </script> 
             <input id="Button1" type="button" name="Button1" value="按钮" onclick="javascript:__doPostBack(’Button1’,’’)">
