推荐答案

您需要动态创建您的stringbuilder中也有一个onclick处理程序，这样您就可以得到这样的内容:

You need to dynamically create an onclick handler in your stringbuilder too, so that you have something like this :

s.Append("<img src=''images/print2.gif'' border=0 onclick=''onclickhandler()''>")

当然，您还需要在生成的html代码中对onclick处理程序本身进行编码.最好先以常规方式尝试此操作，然后再通过stringbuilder创建字符串.

of course you also need to code the onclick handler itself in your generated html code. Better try this in a normal way first and then create the string via a stringbuilder.

<asp:imagebutton id="ImageButton1" runat="server" onclick="ImageButton1_Click" xmlns:asp="#unknown" />

protected void ImageButton1_Click(object sender, EventArgs e)
{
     MessageBox.Show("You clicked on image!");
}

Javascript =>

Javascript =>

s.Append("<img src='images/print2.gif' border='0' style='cursor: hand;' onclick='onclicked()'>");
s.Append("<script type='text/javascript'>function onclicked(){alert('You clicked on image');}</script>")
