什么是 AngularJs?网上一大堆资料,没能真正说明白。
AngularJs 就是一个函数库,算不上一个框架,源码2万2千多行,提供了前端MVC的开发方式,
有双向绑定,指令等特性,这是具有革命性的。我是多么反感jQuery 用选择器 选择元素 ,绑定事件,进行一大堆DOM操作,一旦代码过多,非常不好维护,html结构改变,又要重写js代码,
不过 jQuery 对 ajax的封装 是其他框架 匹敌不了的,接近于标准。
Bootstrap 是一个 css 库,对于搞后端出生的娃,比较友好。
AngularStrap 是一个 在AngularJs 中 使用的 Bootstrap 组件库,比较友好。
对于任意的Javascript 函数库 与 框架,只要Javascript 基础扎实,研究一下,都可以 信手拈来,今天来使用 AngularJs
来实现 省市区联动,来体验一下 AngularJs 双向绑定 不是盖的。
来看看我们的项目结构:
bower_components 下的库、框架 , 是使用bower 安装的 。bower install 库 --save
lib 下面的是我们自己写的js。
