C# 检查单击了哪个ASP.NET

我通常隐藏以下div

<div id="confirmDialog" class="window" style="background-color:#f2f4f7; border:1px solid #d9a0e2; text-align:center; height:100px; position:fixed;  padding:10px;  top:50%  " runat="server" visible="false">
<br /> You already have a leave request on the chosen date. Are you sure you want to submit this request?<br /><br />
<asp:Button ID="BtnConfirm" runat="server" Text="Yes"  Width="60px" />&nbsp;
<asp:Button ID="BtnNo" runat="server" Text="Cancel" onclick="BtnNo_Click" />
</div>

如何通过asp.net/jQuery实现这一点？

可以通过两种方式实现

通过Jquery拦截click事件 在代码中添加其他脚本。

您必须将代码分为两个不同的部分：一个是执行部分，完成后弹出确认对话框，另一个是提交表单以执行其余部分。您不能一次完成这项工作，因为您不能执行服务器端代码，在客户端弹出确认对话框，然后在服务器端继续

你要做的是用伪代码

button1_Click()
{
  Execute_logic;
  use scriptmanager to trigger a JavaScript function that displays the confirmation dialog;
}

JavaScript函数应该：

function askConfirm()
{

  if(confirm('want to continue?'))
     submit_the_form to execute second part of the process();
  else 
     return false;
}

服务器端代码：

//This is the method that should execute after the JavaScript function submits the form
Handler_ForSecondPartOfTheRequest()
{
  execute second part of the logic;
}

检查发送方对象，它将返回控制信息。

function askConfirm()
{

  if(confirm('want to continue?'))
     submit_the_form to execute second part of the process();
  else 
     return false;
}

//This is the method that should execute after the JavaScript function submits the form
Handler_ForSecondPartOfTheRequest()
{
  execute second part of the logic;
}
