有人知道这意味着什么吗？ -：

Type.registerNamespace('Sys');Sys.Res={"argumentInteger":"Value must be an integer.","invokeCalledTwice":"Cannot call invoke more than once.","webServiceFailed":"The server method \u0027{0}\u0027 failed with the following error: {1}","argumentType":"Object cannot be converted to the required type.","argumentNull":"Value cannot be null.","scriptAlreadyLoaded":"The script \u0027{0}\u0027 has been referenced multiple times.

还是这个？ -：

"PRM_UnknownToken":"Unknown token: \u0027{0}\u0027.","PRM_MissingPanel":"Could not find UpdatePanel with ID \u0027{0}\u0027. If it is being updated dynamically then it must be inside another UpdatePanel.","PRM_ServerError":"An unknown error occurred while processing the request on the server. The status code returned from the server was: {0}","PRM_ParserError":"The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled.\r\nDetails: {0}","PRM_TimeoutError":"The server request timed out.","PRM_ParserErrorDetails":"Error parsing near \u0027{0}\u0027.","PRM_CannotRegisterTwice":"The PageRequestManager cannot be initialized more than once."};

我在检查元素时在调试器中收到这些错误。 UpdatePanels 根本不工作。我正在使用 AjaxToolkit。使用 IIS 7.5

我们将不胜感激。

我会检查你的防火墙日志，看看客户端是否被阻止。

我收到此错误的唯一一次是我的防火墙阻止回发，因为它超过了parameter length limit。

您可能会发现，如果您取出更新面板和所有 Ajax 功能，您会从防火墙收到“找不到页面”消息，但 Ajax 功能会“隐藏”用户的错误，所以只有显示在调试器中。

解决方案对我来说是提高 __EVENTVALIDATION perameter 的参数长度限制（在我的情况下为 1600）。现在，可能需要根据您的情况更改不同的限制或参数，但如果您发现防火墙阻止了它，它应该告诉您原因。

“如果一切都失败了，请检查你的防火墙。”

我知道这篇文章有点晚了，但也许这会为其他人节省我必须经历的一周调试和研究。

希望对你有帮助！
