如何从ASP.NET VB背后的代码做modalpopupextender

您好我正在尝试从VB后面的代码加载模式弹出扩展程序。我尝试过使用Javascript，但不确定我的语法是否正确。我尝试使用javascript在前面调用launchModal（）函数，但它似乎没有调用该函数。理想情况下，该函数将搜索模态ID = mp1并加载它。但它不起作用。请帮助，谢谢。

Hi I am trying to load modal pop up extender from code behind VB. I have tried using Javascript but not sure if my syntax is correct. I tried using javascript to call launchModal() function in front but it doesn't seem to be calling the function. Ideally, The function will search for the modal ID = mp1 and load it. But it doesn't work. Please help, thank you.

<pre><div class="box-footer">
                        <asp:Button ID="btnSave" runat="server" Text="Save" onclick="btnSave_Click" class="btn btn-default" Width="100px" />
                        <asp:Button ID="Client" runat="server" Text="Client Side" class="btn btn-default" />
                    </div>
                    <!-- /.box-footer -->
                </div>
            </div>
            <!-- /.box -->
            <!-- general form elements disabled -->
        </div>
    </div>
    <!-- ModalPopupExtender -->
    <cc1:ModalPopupExtender ID="mp1" runat="server" PopupControlID="Panel1" TargetControlID="Client"
        CancelControlID="btnClose" BackgroundCssClass="modal-background">
    </cc1:ModalPopupExtender>
    <asp:Panel ID="Panel1" runat="server" CssClass="modal-popup" align="center" Style="display: none">
        <br />
        <br />
        Group Code cannot be empty<br />
        <asp:Button ID="btnClose" runat="server" Text="Close" />
    </asp:Panel>
    <!-- ModalPopupExtender -->
    <script type="text/javascript">
        function launchModal(){
            var id = $find("mp1");
            if (id)
                id.show();
            else
                alert("Not found");
        }

        //var launch = false;
        //function launchModal() {
        //    launch = true;
        //}
        //function pageLoad() {
        //    if (launch) {
        //        $find("mp1").show();
        //    }
        //}
    </script>
</asp:Content>

我的代码背后

My Code Behind

Protected Sub btnSave_Click(sender As Object, e As EventArgs) Handles btnSave.Click
        If txtGrpCode.Text = "" Then
            Page.ClientScript.RegisterStartupScript(Me.GetType(), "window-script", "launchModal()", True)
            Response.Redirect("frmFm01det.aspx")
        End If

我尝试过：



我尝试使用javascript（不确定我的语法是否正确）来调用infront函数，但它根本不起作用。我甚至不知道如何调试。

What I have tried:

I have tried using javascript(not sure if my syntax is correct) to call the function infront but it doesn't work at all. I don't even know how to debug.
