花瓣这样的模板引擎纯手写的吗


下面是花瓣的一个模板引擎,是不是先写成html再用什么工具能生成


 (function(rt) {
    var templates = rt.templates,
        attrs = function() {
            return rt.attrs.apply(rt, arguments)

模板引擎 JavaScript

茶树菇香鸡 11 years, 2 months ago

这个是模版已经被编译成 Javascript 了,只需要一个运行时就可以做页面渲染。至于模版是不是先写成 HTML,这个不一定,要看模版引擎支持解析什么格式。模版引擎太多了,绝大多数都是这样来实现的,想找一个来试试或者研究的话,可以戳这里: http://garann.github.io/template-chooser/
