实现按回车提交功能

实现功能的js代码:

<script language="javascript">
  
      function ff()
{
   if(event.keyCode==13)
   {
     
      document.getElementbyid("Button2").click();

      event.returnValue = false;
   }
} 

  </script>

调用代码:

<asp:TextBox id="Tbvalidate" runat="server" tabIndex="5" onkeydown="ff();"></asp:TextBox>

<asp:Button id="Button2" runat="server" Text="发表"></asp:Button>
