c# – 另一个ASP.net AJAX SYS未定义错误

Ajax 2022-09-26

我的智慧在这里结束了.我有一个在VS 2008中开发的ASP.net 2.0 Web项目.问题发生在我的dev XP系统和我们的Windows 2000和2008服务器上.
该项目使用AJAX 1并引用System.Web.Extensions 1.0.61025.0和AJAXControlTookKit 1.0.10618.0.

我正在尝试使用ScriptManager和ToolKitScriptManager控件来帮助嵌入javascript文件.

在我尝试嵌入之前,我必须摆脱可怕的SYS未定义的javascript错误.
实际上,如果我使用ScriptManager包含使用Path属性的javascript文件,它可以工作. SYS错误仍然存​​在,但javascript文件包含在生成的页面上,并且它们可以正常工作.现在我正在处理一个只包含一些测试文本的空白页面.此页面包含在包含空ScriptManager的MasterPage中.

当我调试此页面时,我在Sys.WebForms.PageRequestManager上收到错误(请参阅下面生成的HTML).

我已经卸载并重新安装了AJAX,将System.Web.Extensions复制到我的bin中,检查了我的web.config设置至少50次&并且已经访问了很多搜索结果页面,论坛和博客.

我知道这可能是我想要的简单事情.我的缩写代码在下面,有人可以帮助我思考这个并抓住我所缺少的东西.

谢谢

解决方法:

我以前遇到过这个问题,

在ajaxtoolkit中搜索嵌入的javascript文件,并查看其修改日期.
并确保不会在将来.

为了确保这一点,检查链接出现在viewsource中* .axd并尝试运行eveyone,如果你看到有人回复错误,在这里你发现了问题.

致以我的问候
