angular 模块化之directive

通过使用directive使页面模块化。需要哪部分直接调用即可。原本这些操作需要后端配合，现在前端即可。将原本的html代码拆为不同的模块，然后通过directive衔接加载到主页面中。首先页面通过directive包含进来，然后重新建一个module，将这个新的module注入到主module中。
主要可以看directive.js文件中的var app = angular.module("store-directives",[]);
app.js文件中的var app = angular.module('gemStore', ["store-directives"]);这一句就和上面的那句正好对应上，将store-directives注入到了主模块中
另外，别忘了将directive.js文件在html的主文件中进行加载。
关于directive的具体用法EAC和templateUrl，与html对应的关系等等具体这里就不说了。
补充说明：
angular中为了js书写规范和清晰，建议用(function(){})();包住原本的代码。
ng-include也可以直接将html引入到主页面中，进行模块化，需要注意的是，ng-include加载进来的模块的是需要一对双引号和一对单引号的。即： ng-include="'product-description.html'"
可以给controller定义别名，这样页面中调用的值可以通过点别名来加载，这样有利于模块化数据，使页面数据更清晰。一眼便知是哪一个模块的数据。
关于别名和controller，别名和controller都可以直接写到directive中，具体的代码看directive.js文件中productGallery和productTabs这两个directive便知。全部完整的代码已经全部贴出。
