用 ok 创建一个消息框并取消 asp.net

Question

在我的网页中，我有这个 javascript 来向用户显示一个消息框

  Private Sub MessageBox(ByVal msg As String)
        Dim lbl As New Label

        lbl.Text = "<script language='javascript'>" & Environment.NewLine &
           "window.alert('" + msg + "');" & Environment.NewLine &
           "document.location = 'Clinica.aspx';</script>"
        Page.Controls.Add(lbl)
    End Sub

我想知道的是是否可以在其中放置一个“确定”和一个“取消”按钮，所以在 vb.net 中会是这样的

                  MsgBox(vbCritical _
                   & "Os dados da marcação actual foram alterados!" & vbCrLf _
                   & "Mudando a marcação selecciona irá perder as alteraçãoes" & vbCrLf _
                   & vbCrLf _
                   & "Deseja continuar?", _
                   vbOKCancel, _
                    "ATENÇÃO!")

我是 javascript 新手，我想知道这样的事情是否可行，谢谢。

jsconfirm('Confirmation text')怎么样？

https://developer.mozilla.org/en-US/docs/Web/API/Window/confirm

所以你的代码会像这样运行：

 lbl.Text = "<script language='javascript'>" & Environment.NewLine &
      "if(window.confirm('" + msg + "')) document.location = 'Clinica.aspx';</script>"
