Question

我试图找出how to display confirm box when drop down list's selected indexchanged事件被触发。

通过某个论坛浏览我遇到了以下解决方案，但我不知道如何使用它，因为我在c＃中工作。我如何使其工作？我甚至不确定这是否真的是我的问题的解决方案。请帮帮忙。谢谢。

Public Sub ConfirmOnChange()
            'Register the script block
            If Not IsStartupScriptRegistered("CSP-ddl-onchange") Then
                RegisterStartupScript("CSP-ddl-onchange", _
                    "<script language=""JavaScript"">" & _
                    "var CSP_savedDDLID = " & _
                     "document.getElementById('" & _
                     ddl.ClientID & "').value;" & vbCrLf & _
                    "function resetDDLIndex() {" & vbCrLf & _
                    " document.getElementById('" & _
                     ddl_Status.ClientID & "').value = CSP_savedDDLID;" & _
                    vbCrLf & _
                    "}" & vbCrLf & _
                    "</script>")
            End If
            Dim msg As String = "'Do you want to change selection?';"
            ddl_Status.Attributes("onchange") = _
            "if (!confirm('" & msg.Replace("'", "\'") & _
            "')) resetDDLIndex(); "
        End Sub

public void ConfirmOnChange()
{
    //Register the script block
    if(!IsStartupScriptRegistered("CSP-ddl-onchange"))
    {
        RegisterStartupScript("CSP-ddl-onchange",
            "<script language=\"JavaScript\">" +
            "var CSP_savedDDLID = " +
                "document.getElementById('" +
                ddl.ClientID + "').value;" + "\r\n" +
            "function resetDDLIndex() {" + "\r\n" +
            " document.getElementById('" +
                ddl_Status.ClientID + "').value = CSP_savedDDLID;" +
            "\r\n" +
            "}" + "\r\n" +
            "</script>");
    }
    string msg = "'Do you want to change selection?';";
    ddl_Status.Attributes("onchange") = "if (!confirm('" & msg.Replace("'", "\'") +
    "')) resetDDLIndex(); ";
}
