              {
                // logic
              }

推荐答案

您必须在设计如下所示的按钮的OnClientClick事件中调用javascript.

You have to call the javascript in the button''s OnClientClick event in design like below.

<asp:Button ID="btn" runat="server" OnClientClick="GetResult()"/>

问题是单击事件被执行后，我得到了确认框.
那是因为您正在服务器端的click事件上调用Javascript函数.删除该行，并在您的asp:Button标记上，添加OnClientClick ，然后将其指向您的Javascript函数.

The problem is i get the confirm box after the click event gets executed.
That is because you are calling the Javascript function on the server side click event. Remove that line and on your asp:Button tag, add OnClientClick and then point it to your Javascript function.
