ng-repeat高级用法:

遍历数组:
    <li ng-repeat="item in array">{{item}}</li>

遍历对象:
    key:对象的key
    value:对象的value
    <li ng-repeat="(key,value) in obj">{{key}} | {{value}}</li>

绑定$$haskKey:
    给每个item绑定唯一ID,当数组发生变化时,ID不变!
    <li ng-repeat="item in items track by $id(item)"></li>

过滤器:
    对item的每个属性进行模糊匹配
     <li ng-repeat="item in items |filter: 25"></li>

绑定属性过滤:
   对item的某个属性进行模糊匹配
    <li ng-repeat="item in items |filter: 25 track by item.age"></li>

保存匹配结果:
    把匹配到的结果另存到results数组变量,可供外部使用
    <li ng-repeat="item in items |filter: 25 as results"></li>

保存针对某个属性的过滤结果:
    <li ng-repeat="item in items |filter: 25 as results track by item.age "></li>
