问如何在没有回发的情况下在按钮点击时重定向到相同的页面区域？

EN

<asp:Button ID="Button1" runat="server"       
     OnClientClick="document.location.href+='#locA';return false;" />

   <script>
        function cGoTo(where)
        {
            // take care if any other anhor exist to remove it.
            var url = document.location.href
            var tempArray = url.split("#");
            var baseURL = tempArray[0];

            document.location.href = baseURL + "#" + where;
        }
    </script>    
    <asp:Button ID="Button2" runat="server" OnClientClick="cGoTo('locA');return false;" />
