我正面临来自 ASP.NET Ajax Controls Toolkit ModalPopupExtender 的错误行为,当我Alert()
从服务器端调用 JavaScript 函数时,模式出现在后台。我不知道为什么会这样。
这是代码:
VB:
Sub ShowAlert(ByVal message As String)
ScriptManager.RegisterStartupScript(Me.UpdatePanel, UpdatePanel.GetType(), "notificationScript", "<script language='JavaScript'> alert('" & message & "'); </script>", False)
End Sub
aspx:
<asp:UpdatePanel ID="UpdatePanel" runat="server">
<ContentTemplate>
<asp:Panel ID="pnlPartialInstructions" CssClass="modal" runat="server">
......
<asp:Panel ID="pnlPrintConfirmation" CssClass="modal" runat="server">
<table class="ui-accordion">
<tr>
<td colspan="2">
<asp:Label Text="Do you want to print the receipt?" ID="lblPrintConfirmation" runat="server"
meta:resourcekey="lblPrintConfirmationResource1" Font-Bold="True" Font-Names="tahoma"
Font-Size="Large" />
</td>
</tr>
<tr>
<td>
<asp:Button ID="btnConfirmPrint" Text="Yes" CssClass="google-button google-button-blue"
runat="server" meta:resourcekey="btnConfirmSaveResource1" Font-Size="Large" />
</td>
<td>
<asp:Button ID="btnCancelPrint" Text="No" CssClass="google-button google-button-red"
runat="server" meta:resourcekey="btnCancelSaveResource1" Font-Size="Large" />
</td>
</tr>
</table>
</asp:Panel>
<asp:Button ID="HiddenForModel1" Text="" runat="server" CssClass="hide" CausesValidation="False" />
