ng不同controller之间传参

父作用域与子作用域

<div ng-controller="parent">
  <p>data in parent controller : {{data.name}}</p>
  <div ng-controller="child">
    <input type="text" ng-model="data.name">
  </div>
</div>

var myApp = angular.module('myApp', []);
    myApp.controller('parent', function  ($scope) {
         $scope.data = {
            name: '123'
        }
    }); 
    myApp.controller('child', function  ($scope) {
        $scope.name = '';
    }); 

平行作用域

方法一、使用$rootScope直接绑定，这个就比较简单了，之前我的一篇博文也讲过

方法二、注入服务

<div ng-controller="first">
      <input type="text" ng-model="name">     
      value:{{name}} 
      <button ng-click="set()">set</button>
</div>
<div ng-controller="second">
    value:{{name}}
</div>

var myApp = angular.module('myApp', []);
    myApp.factory('myService', function() {
        var savedData = '';
        function set(data) {
           savedData = data;
        }
        function get() {
             return savedData;
        }
        return {
          set: set,
          get: get
        }
    });
    myApp.controller('first', function ($scope, myService, $rootScope){
        $scope.name = '';
        $scope.set = function (){
            myService.set($scope.name);
            console.log($scope.name);
            $rootScope.$broadcast('send');
        }
        
    });
    myApp.controller('second', function ($scope, myService, $rootScope){
        $rootScope.$on('send', function (){
            $scope.name = myService.get();    
        });        
    });

方法三、基于localStorage

<div ng-controller="first">
      
</div>
<div ng-controller="second">
    value:{{value}}
</div>

var myApp = angular.module('myApp', []);
    myApp.controller('first', function ($scope) {
      localStorage.setItem("key","value");
    });
    myApp.controller('second', function ($scope){
        $scope.value = localStorage.getItem('key');
    })
