angularjs1.5 组件内用函数向外传值的实例

组件：

.component('homeCityListCom',{
  bindings: {
  list: '<',
  cityname:'&'
 },
 controllerAs: 'vm',
 template:
 `
 <div class="cityListBox">
  <span class="title">按拼音首字母选择</span>
  <div class="cityItem flexRowStart" ng-repeat="x in vm.list track by $index">
   <p class="zimu flexColumnCenter">{{x.sortName}}</p>
   <ul class="flexRowStart city">
    <li ng-repeat="c in x.cities"><a href="/#!/home?city_id={{c.cityId}}" rel="external nofollow" ng-click="vm.cityname({name: c.cityName})">{{c.cityName}}</a></li>
   </ul>
  </div>
 </div>`
})

控制器：

.controller('cityListCtrl', ['$scope','$http', function ($scope,$http) {
 let that = this;
 // 将城市名字存在本地
 that.cityName = function(name){
  console.log(123);
  localStorage.setItem('cityName', name);
 }
}])

使用组件：

<home-city-list-com list="cl.cityList" cityname="cl.cityName(name)"></home-city-list-com>

路由设置：

.state('city_list',{
   url:"/city_list",
   templateUrl:'templates/indexTpl/city_list.html',
   controllerAs:'cl',
   controller:'cityListCtrl'
  })
