解决方法
The docs给你所有你需要知道的信息：
A jQuery Mobile site must start with an HTML5 ‘doctype’ to take full advantage of all of the framework’s features. (Older devices with browsers that don’t understand HTML5 will safely ignore the ‘doctype’ and varIoUs custom attributes.) In the ‘head’,references to jQuery,jQuery Mobile and the mobile theme CSS are all required to start things off.
总之，是的，jQuery核心是必需的。
