Open
Description

<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>
