i想要

i used the below code in my application,it show the authenticate screen when user click yes and it also shows authenticate screen when the user click cancel

i want the

authenticate 

屏幕



我尝试过： < br $>

screen only when the user press yes

What I have tried:

function Confirm() {
    var confirm_value = document.createElement("INPUT");
    confirm_value.type = "hidden";
    confirm_value.name = "confirm_value";
    if (confirm("Do you want to Delete data?")) {
        confirm_value.value = "Yes";
    } else {
        confirm_value.value = "No";
    }
    document.forms[0].appendChild(confirm_value);
}

<li><asp:LinkButton ID="lnk_Delete" runat="server"  OnClientClick="javascript:Confirm();javascript:return OpenSwipWindowAction('Delete','')"><img src="../images/Document_Delete.png" alt="" />Delete</asp:LinkButton></li>

Dim confirmValue As String

ElseIf hdnModuleName.Value = "Delete" Then
                confirmValue = Request.Form("confirm_value")
                If confirmValue = "Yes" Then
                    Label12.Text = "yes"
                Else

                    Label12.Text = "No"
                End If

推荐答案

我认为这是代码应该是什么样子

按钮点击提示确认

I think this is how the code should look like
On button click prompt confirm

<asp:LinkButton ID="lnk_Delete" runat="server"  

        OnClientClick="return Confirm();">
        <img src="../images/Document_Delete.png" alt="" />Delete</asp:LinkButton>

如果是，请设置隐藏值和调用返回OpenSwipWindowAction（...）（假设它返回true | false）

else（取消），返回false，什么都不做（我假设）

If yes, set hidden value and call return OpenSwipWindowAction (...) (Assuming it return true | false)
else (Cancel), return false, do nothing ( I'm assuming )

<script>
        function Confirm() {
            var confirm_value = document.createElement("INPUT");
            confirm_value.type = "hidden";
            confirm_value.name = "confirm_value";
            if (confirm("Do you want to Delete data?")) {
                confirm_value.value = "Yes";

                document.forms[0].appendChild(confirm_value);

                return OpenSwipWindowAction('Delete', '');
                
            } else {
                confirm_value.value = "No";
                return false;
            }

            document.forms[0].appendChild(confirm_value);
        }
    </script>
