.aspx 前台调用如下：
1 <asp:Button ID="btnSubmit" runat="server" Text="提交" OnClick="btnSubmit_Click" OnClientClick="return ShowMsg('btnSubmit','','请你确定','你确定要提交吗？',2,null);" />
注意：因为JS提交到服务器需要用到 __EVENTTARGET 、__EVENTARGUMENT ，要是执行时提示__EVENTTARGET为空则加入一个LinkButton控件就可以了，如：<asp:LinkButton ID="l" runat="server" style="display:none;" />
效果如下：
