Microsoft JScript运行时错误:'Sys.Extended.UI'为null或不是对象

Question

我的页面有问题.当它打开时,它会显示以下错误消息:

Microsoft JScript运行时错误:'Sys.Extended.UI'为null或不是对象

<ajax:ToolkitScriptManager ID="tsm" runat="server" CombineScripts="false" >

    </ajax:ToolkitScriptManager>

并显示错误

$create(Sys.Extended.UI.ModalPopupBehavior, {"BackgroundCssClass":"modalBackground1","DropShadow":true,"PopupControlID":"ctl00_ContentPlaceHolder1_panelPopupAddDefaultAddress","PopupDragHandleControlID":"ctl00_ContentPlaceHolder1_panelPopupAddDefaultAddressDragHandle","dynamicServicePath":"/SJM.Framework.Website/Order/ActiveOrders.aspx","id":"ctl00_ContentPlaceHolder1_modalPopupAddDefaultAddress"}, null, null, $get("ctl00_ContentPlaceHolder1_hiddenTargetControlForModalPopup"));

任何人都可以告诉我我的问题是什么.我试过了,但我还没找到.

Answer 1

我收到此错误是因为某处我使用的是ScriptManager而不是ToolkitScriptManager.我用Took工具包脚本管理器应用程序取代脚本管理器的那一刻开始正常工作.

希望这有助于某人!
