推荐答案

如果使用VS2005，则问题通常是由于web.config配置引起的.在system.web部分的web.config中添加以下配置.

If you use VS2005 the problem is generally because of web.config configuration. Add the following configuration in web.config in system.web section.

<httpHandlers> <remove verb="*" path="*.asmx"/>
            <add verb="*" path="*.asmx" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory"/>
            <add verb="GET,HEAD" path="ScriptResource.axd" type="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" validate="false"/>
        </httpHandlers>

如果使用VS2008，则问题通常是因为JavaScript太早引用了Sys命名空间.

在这里，看看这些文章和讨论它们的博客文章以及如何解决它:

If you use VS2008, the problem is generally because of JavaScript that references the Sys namespace too early.

Here, have a look at these articles and blog posts discussing the same and how to resolve it:
