前端排错表

首先，是否有拼写错误?

JSP 模板

在 HTML 靠前的位置使用 script 标签初始化 JS 变量，不要使用 <input type="hidden" name="id" id="id" value="${id}" />

IDEA

Make 不编译 java 文件

File -> Project Structure -> Modules -> 选择一个主项目 -> Paths： 这里配置编译输出路径

项目配置读取错误

复制 src 目录下的配置文件到输出路径下，[TODO] 编译的时候为啥没有复制配置文件呢？

jQuery

Related: [Why you don't need jQuery as an abstraction][2]

$ itself is a god object. Everything goes on it. The standard plugin / extension architecture that is recommended is to just bolt more methods on $ itself!

Surely this is bad. An example would be how we have both $.load which is overloaded to do completely different things. If they were on two separate sensibly named objects $Container.load and $EventTarget.load. Personally I would deprecate the latter in favour of .on('load'

The animation should be it's own little modular thing, not bolted onto $. Ajax should be it's own little modular thing, not bolted onto $
