c#中的条件确认框

Question

如何从 C# 调用条件确认框。

我有 2 个隐藏字段，根据条件我想调用确认框。

之后我还想要用户按下了什么（点击是或否）。

设计：-

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

代码:-

   protected void Next_Click(object sender, EventArgs e)
     {
            if (hdnDefault.Value == hdnPrimary.Value) { return; }
            else
            {
            //open confirm box 
            ScriptManager.RegisterStartupScript(Page, Page.GetType(), "confirm", "confirm('Do you want to save new default payment method?');", true);
                    string confirmValue = Request.Form["confirm_value"];
                    if (confirmValue == "Yes")
                    {
                        this.Page.ClientScript.RegisterStartupScript(this.GetType(), "alert", "alert('You clicked YES!')", true);
                    }
                    else
                    {
                        this.Page.ClientScript.RegisterStartupScript(this.GetType(), "alert", "alert('You clicked NO!')", true);
                    }
            }
     }

我试过下面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);
        }

Answer 1

我没有运行你的代码。但是当您有 runat="server" 作为输入控件时，它将附加 asp.net 唯一 ID。因此，请尝试通过以 btnAddPaymentMethod 结尾的名称访问输入控件，如下所示。

从 $('#btnAddPaymentMethod').click(); 更改为 $('[id$=btnAddPaymentMethod]').click();

Answer 2

此 jQuery 代码将打开一个带有 'ok' 和 'cancel' 按钮的确认对话框。

这里有一个id为myConfirmPageLink的锚标签，点击后会要求确认。如果单击“确定”，它将继续到目标，如果单击“取消”，它将停留在同一页面上。

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

这应该很容易根据您的目的进行修改。

protected void Next_Click(object sender, EventArgs e)
{
  if (hdnDefault.Value == hdnPrimary.Value) { 
    return; 
  } else {
    //open confirm box 
    ScriptManager.RegisterStartupScript(Page, Page.GetType(), "confirm", "Confirm('Do you want to save new default payment method?');", true);
  }
}

protected void AddPaymentMethod_Click(object sender, EventArgs e)
{
  string confirmValue = Request.Form["confirm_value"];
  if (confirmValue == "Yes") {
    ScriptManager.RegisterStartupScript(this.GetType(), "alert", "alert('You clicked YES!')", true);
  } else {
    ScriptManager.RegisterStartupScript(this.GetType(), "alert", "alert('You clicked NO!')", true);
  }
}

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