function FindUrl(url)   

{   

    temp = selectUrl(url);   

    frame1.src=temp;  

    return false;//将完不成提交事件，就不提交服务器

}



<asp:LinkButton ID="LinkButton1" runat="server" Width="32px" OnClientClick="return FindUrl('1');">Part1</asp:LinkButton>

少了return false控制页面不回刷改成如下：



<asp:LinkButton ID="LinkButton1" runat="server" Width="32px" OnClientClick="FindUrl('1');return false">Part1</asp:LinkButton>   

<asp:LinkButton ID="LinkButton2" runat="server" Width="32px" OnClientClick="FindUrl('2');return false">Part2</asp:LinkButton>
