只需简单地执行(在v1.3.15中测试):

<article ng-controller="ctrl1 as c1">
    <label>Change name here:</label>
    <input ng-model="c1.sData.name" />
    <h1>Control 1: {{c1.sData.name}}, {{c1.sData.age}}</h1>
</article>
<article ng-controller="ctrl2 as c2">
    <label>Change age here:</label>
    <input ng-model="c2.sData.age" />
    <h1>Control 2: {{c2.sData.name}}, {{c2.sData.age}}</h1>
</article>

<script>
    var app = angular.module("MyApp", []);

    var dummy = {name: "Joe", age: 25};

    app.controller("ctrl1", function () {
        this.sData = dummy;
    });

    app.controller("ctrl2", function () {
        this.sData = dummy;
    });

有许多方法可以在控制器之间共享数据

使用服务 使用美元的状态。去服务 使用stateparams 使用rootscope

各方法说明:

I am not going to explain as its already explained by someone using $state.go $state.go('book.name', {Name: 'XYZ'}); // then get parameter out of URL $state.params.Name; $stateparam works in a similar way to $state.go, you pass it as object from sender controller and collect in receiver controller using stateparam using $rootscope (a) sending data from child to parent controller $scope.Save(Obj,function(data) { $scope.$emit('savedata',data); //pass the data as the second parameter }); $scope.$on('savedata',function(event,data) { //receive the data as second parameter }); (b) sending data from parent to child controller $scope.SaveDB(Obj,function(data){ $scope.$broadcast('savedata',data); }); $scope.SaveDB(Obj,function(data){`enter code here` $rootScope.$broadcast('saveCallback',data); });

我不喜欢使用$watch。您可以只分配数据，而不是将整个服务分配给控制器的作用域。

JS:

var myApp = angular.module('myApp', []);

myApp.factory('MyService', function(){
  return {
    data: {
      firstName: '',
      lastName: ''
    }
    // Other methods or objects can go here
  };
});

myApp.controller('FirstCtrl', function($scope, MyService){
  $scope.data = MyService.data;
});

myApp.controller('SecondCtrl', function($scope, MyService){
   $scope.data = MyService.data;
});

HTML:

<div ng-controller="FirstCtrl">
  <input type="text" ng-model="data.firstName">
  <br>Input is : <strong>{{data.firstName}}</strong>
</div>
<hr>
<div ng-controller="SecondCtrl">
  Input should also be here: {{data.firstName}}
</div>

或者，您可以使用直接方法更新服务数据。

JS:

// A new factory with an update method
myApp.factory('MyService', function(){
  return {
    data: {
      firstName: '',
      lastName: ''
    },
    update: function(first, last) {
      // Improve this method as needed
      this.data.firstName = first;
      this.data.lastName = last;
    }
  };
});

// Your controller can use the service's update method
myApp.controller('SecondCtrl', function($scope, MyService){
   $scope.data = MyService.data;

   $scope.updateData = function(first, last) {
     MyService.update(first, last);
   }
});

正如@MaNn在接受的答案的一个评论中指出的那样，如果页面被刷新，解决方案将无法工作。

解决方案是使用localStorage或sessionStorage来临时持久化希望跨控制器共享的数据。

Either you make a sessionService whose GET and SET method, encrypts and decrypts the data and reads the data from either localStorage or sessionStorage. So now you use this service directly to read and write the data in the storage via any controller or service you want. This is a open approach and easy one Else you make a DataSharing Service and use localStorage inside it - so that if the page is refreshed the service will try and check the storage and reply back via the Getters and Setters you have made public or private in this service file.

有多种方法可以做到这一点。

事件——已经解释得很好了。 UI路由器-上面解释了。 Service -使用上面显示的更新方法 坏——注意变化。 另一种父-子方法而不是发射和广播-
