javascript实现控件的可见性asp.net里面

我想这样写的javascript:
<script language="javascript">
    function ShowCaleter(i)
    {one = document.getElementById("Calendar1");Calendar1日期控件的id
     if(i==1)
      one.Style.Display="none";
     else
       one.Style.display="";//显示
    }
        </script>
vs2003这样调用的：
private void Button1_Click(object sender, System.EventArgs e)
        {
         Page.Response.Write("<script   language=javascript>ShowCaleter(2)</script>");
        }
可是怎么不行?????
