没有引入JS或JS引入的顺序不对吧？

这是两个问题啊。第一个在Global.asax文件中的Application_Start()方法添加下面的代码

ScriptManager.ScriptResourceMapping.AddDefinition("jquery", new ScriptResourceDefinition
            {
                Path = JQ发布文件地址,
                DebugPath = JQ开发版本地址,
                CdnPath = JQ发布版本CDN地址
                CdnDebugPath = JQ开发版本CDN地址
            });

第二个是引号的问题。这个自己检查下，至少把语法写对吧。
