ng-repeat高級用法: 遍歷數組: <li ng-repeat="item in array">{{item}}</li> 遍歷對象: key:對象的key value:對象的value <li ng-repeat="(key,value) in obj">{{key}} | {{value}}</li> 綁定$$haskKey: 給每一個item綁定惟一ID,當數組發生變化時,ID不變! <li ng-repeat="item in items track by $id(item)"></li> 過濾器: 對item的每一個屬性進行模糊匹配 <li ng-repeat="item in items |filter: 25"></li> 綁定屬性過濾: 對item的某個屬性進行模糊匹配 <li ng-repeat="item in items |filter: 25 track by item.age"></li> 保存匹配結果: 把匹配到的結果另存到results數組變量,可供外部使用 <li ng-repeat="item in items |filter: 25 as results"></li> 保存針對某個屬性的過濾結果: <li ng-repeat="item in items |filter: 25 as results track by item.age "></li>
