C# c语言中的条件确认框#

如何从c#调用条件确认框

我有2个隐藏字段，根据我想要调用确认框的条件

之后，我还想知道用户按下了什么（单击是或否）

设计：-

  <input type="submit" id="btnAddPaymentMethod" onserverclick="AddPaymentMethod_Click" runat="server" value="add payment method" />

我尝试了以下jQuery代码：-

 function Confirm(msg) {
            var confirm_value = document.createElement("INPUT");
            confirm_value.type = "hidden";
            confirm_value.name = "confirm_value";
            if (confirm(msg)) {
                confirm_value.value = "Yes";
                $('#btnAddPaymentMethod').click();
            } else {
                confirm_value.value = "No";
            }
            document.forms[0].appendChild(confirm_value);
        }

我没有运行你的代码。但是，当您为输入控件设置了

runat=“server”

时，它将附加asp.net唯一Id。因此，请尝试按输入控件的名称（以

btnAddPaymentMethod

结尾）访问该输入控件，如下所示

---

更改为

$（'#btnAddPaymentMethod'）。单击（）

到

$（'[id$=btnAddPaymentMethod]'）。单击（）
此jQuery代码将打开一个确认对话框，其中包含“确定”和“取消”按钮

在这里，一个id为MyConfigrmPageLink的锚定标记在单击时将请求确认。如果单击“确定”，它将前进到目标，如果单击“取消”，它将保持在同一页面上

$("a#myConfirmPageLink").click(function(){
    return confirm("Are you sure you want to go to that page/site ?");
});

出于您的目的，这应该很容易修改。
为什么不在javascript/jquery中设置条件，以便您可以直接调用确认而不是服务器端代码。请尝试此链接@Sunny Singh我看过那篇文章@jose，但我没有得到任何确认框，它总是显示“您单击了否！”。。
