Question

我已经使用Visual Studio开发了Outlook加载项。我的插件有一个按钮，可在会议邀请的正文中填充详细信息并添加所需的与会者。这种方法在99％的时间内都有效，但是，每隔一段时间它就会给我以下javascript错误

Uncaught TypeError: Cannot read property 'BeginRequestEventArgs' of undefined

如果我然后调试后面的代码并在按钮click事件上设置一个断点，则该断点甚至都不会被击中。

如果我刷新插件的任务窗格，则它将再次开始工作20次或30次单击，这是完全随机的间隔。我的页面上确实有脚本管理器和更新面板，似乎认为这是造成此问题的原因。

这是我的页面：

<body>

<form id="form1" runat="server">
    <asp:ScriptManager runat="server" ID="sm" EnablePageMethods="True"></asp:ScriptManager>

    <div class="ms-Fabric content-main">

        <asp:UpdatePanel ID="updatepanel" runat="server" UpdateMode="Conditional">
            <ContentTemplate>

                <asp:HiddenField ID="Hid1" runat="server" ClientIDMode="Static" Value="Add VC Details" />
                <asp:HiddenField ID="HidCallID" runat="server" ClientIDMode="Static" />
                <asp:HiddenField ID="HidToken" runat="server" ClientIDMode="Static" />
                <asp:HiddenField ID="HidPasscode" runat="server" ClientIDMode="Static" />
                <asp:HiddenField ID="HidStart" runat="server" ClientIDMode="Static" />
                <asp:HiddenField ID="HidEnd" runat="server" ClientIDMode="Static" />

                <asp:HiddenField ID="HidPrevCallID" runat="server" ClientIDMode="Static" />
                <asp:HiddenField ID="HidPrevToken" runat="server" ClientIDMode="Static" />

                <div id="wrapper">
                      <asp:Label ID="Label1" runat="server" Text=""></asp:Label>

                    <asp:Button ID="btn_add" runat="server" Text="Add VC Details" UseSubmitBehavior="False" />
                    <asp:Button ID="btn_trigger" runat="server" Text="" Style="display: none" UseSubmitBehavior="False" />
                    <asp:Button ID="btn_update" runat="server" Text="" Style="display: none" UseSubmitBehavior="False" />
                </div>
                <div id="footer">
                    <asp:Label ID="lab_user" runat="server" Text=""></asp:Label>
                    <asp:Button ID="btn_logout" runat="server" Text="Sign Out" />
                </div>
            </ContentTemplate>
        </asp:UpdatePanel>
    </div>
</form>

这是添加按钮后面的代码：

    Private Sub btn_add_Click(sender As Object, e As EventArgs) Handles btn_add.Click
    If Hid1.Value = "Add VC Details" Then
        Dim callID As Integer = getvmr()

        Dim pn As New Random
        Dim Passcode As Integer = pn.Next(1000, 9999)

        Dim tk As New Random
        Dim token As Integer = tk.Next(10000, 99999)

        Dim script As String = "prependItemBody(" & callID & ", " & Passcode & ", " & token & ")"
        Dim scriptKey As String = "UniqueKeyForThisScript" & Passcode
        System.Web.UI.ScriptManager.RegisterClientScriptBlock(Page, GetType(Page), scriptKey, script, True)

        btn_add.Text = "Update Details"
        Hid1.Value = "Update Details"

    ElseIf Hid1.Value = "Update Details" Then

        Dim callID As Integer = getvmr()

        Dim pn As New Random
        Dim Passcode As Integer = pn.Next(1000, 9999)

        Dim tk As New Random
        Dim token As Integer = tk.Next(10000, 99999)

        Dim script As String = "updateItemBody(" & callID & ", " & Passcode & ", " & token & ")"
        Dim scriptKey As String = "UniqueKeyForThisScript"
        ScriptManager.RegisterStartupScript(Me.Page, Me.GetType(), scriptKey, script, True)

        Hid1.Value = "Update Details"
        btn_add.Text = "Update Details"

    End If

End Sub

Outlook加载项，无法读取未定义的属性'BeginRequestEventArgs'
