推荐答案

试试这个：



在.aspx文件中

Hi,

Try this:

In .aspx file

<form runat="server">
       <asp:button id="btn1" runat="server" onclientclick="confirming();" onclick="btn1_Click" text="Submit" xmlns:asp="#unknown" />
 </form>
   <script type="text/javascript">
       function confirming() {
           document.getElementById('<%=confirmValue.ClientID%>').value = confirm('Yes or no?');
       }
   </script>

在.aspx.cs文件中：

In .aspx.cs file:

protected void btn1_Click(object sender, EventArgs e)
      {
          string confirmValueStr = confirmValue.Value;
          bool confirmValueBool;
          if (bool.TryParse(confirmValueStr, out confirmValueBool)
          {
              // now, confirmValueBool is the value of the confirm function
          }
          else
          {
              // can't convert confirmValueStr to confirmValueBool
          }
      }

希望这会有所帮助。

之前我做的是创建一个< asp：hiddenfield xmlns：asp =＃unknown/>然后在我的javascript中我将HiddenField的值设置为变量的值with document.getElementById（ HiddenFieldID ）。value = variable。

所以在你的情况下它会是这样的：



HTML：



< ; asp：hiddenfield id =Msgrunat =server/>



Javascript：



document.getElementById（Msg）。value = msgbox.value（不确定获取msgbox的值）



然后在后面的代码中你可以只需参考Msg.Value



希望这有帮助

What I have done before is create a <asp:hiddenfield xmlns:asp="#unknown" /> then in my javascript I set the HiddenField's value to that of the variable with document.getElementById("HiddenFieldID").value = variable.
So in your case it would be something like:

HTML:

<asp:hiddenfield id="Msg" runat="server"/>

Javascript:

document.getElementById("Msg").value = msgbox.value(not sure about getting the value of the msgbox)

and then in the code behind you could just reference the Msg.Value

Hope this helps
