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'
  })
