推荐答案
您可以创建一个对象的角度服务，将在它有各种各样的共享特性。你可以将该变量直接分配与控制器范围的变量。因此，通过两个控制器变量使用参考是相同的，就像我们给了 myCtrl1 和 myCtrl2 将只有在那里范围的变量一个副本。因此，在一个变量的变化更新的另一个。
You could create an object in angular service,that will have various shareable properties in it. You could directly assign that variable with your controller scope variable. So that the reference of variable use by both controller are the same, like we gave to myCtrl1 and myCtrl2 will have only one copy in there scope variable. So changes in one variable updates the other one.

<body>
<div ng-controller="myCtrl1">
1st Controller
<input type="text" ng-model="model1.prop1" />
<input type="text" ng-model="model1.prop2" />
</div>
<div ng-controller="myCtrl2">
2nd Controller
<input type="text" ng-model="model2.prop1" />
<input type="text" ng-model="model2.prop2" />
</div>
</body>
app.service('dataService', function(){
var dataService = this;
dataService.model = {
'prop1': '',
'prop2': '',
}
})
控制器1
app.controller('myCtrl1', function($scope, dataService){
$scope.model1 = dataService.model;
});
控制器2
app.controller('myCtrl2', function($scope, dataService){
$scope.model2 = dataService.model;
});
