Question

asp.net中图片热点的Onclick事件怎样单击热点去执行后台（服务端）代码呢？

Answer 1

用服務器控件，比如：ImageButton

Answer 2

VS2005中的ImageMap控件就是针对楼主的问题!
在HotSpots属性中分割设置热点!(但相当麻烦)
楼主可在Dreamweaver中做,相当简单!!

<asp:ImageMap ID="ImageMap1" runat="server" HotSpotMode="PostBack" 
        ImageUrl="http://www.csdn.net/Images/logo_csdn.gif" onclick="ImageMap1_Click">
        <asp:RectangleHotSpot HotSpotMode="PostBack" PostBackValue="csdn" Right="20" Top="0" Bottom="20" />
        <asp:RectangleHotSpot HotSpotMode="PostBack" PostBackValue="test" Left="30" Right="60" Top="0" Bottom="20" />
    </asp:ImageMap>
    protected void ImageMap1_Click(object sender, ImageMapEventArgs e)
        {
            if (e.PostBackValue == "csdn")
            {
                Response.Write("csdn");
            }
            else
            {
                Response.Write(e.PostBackValue);
            }
        }
