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}}" 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'
})
