freemarker
freemarker是静态模板，和html 、jsp类似，我第一次看见后缀是 .ftl文件，我嚓，这是什么鬼，原来是freemarker，使用它的时候你就可以理解前端页面和jsp什么没什么区别，怎样学习它，先分析代码，然后再去使用，不主张去看freemarker的书籍详细介绍，然后忘记了，浪费时间，当我们用到了不懂的在上网去学习，不废话了，先拿一片freemarker文件来分析

从头分析啊，它并不是很神气的东西，
<#assign topnav="teacher"> 你看下assign这个东西 相当于保持变量 topnav里面就放入这个值，然后js就可以拿到这个值了，说到js，大家一定要把js文件放到末尾，不要放在开头的地方，因为放在开头，有些页面还没加载完，但是我调用了那个页面里面的Id或者class，那么就会报错，很头疼的，半天都不知道哪里出来错误，所以建议养成好的习惯，把js文件放在末尾，等页面加载完了，在调用js，题外话了，但是大家得了解<pre name="code" class="html"><!-- CSS -->
