Question

我想使用从一个控制器到另一个控制器的数据，任何人都可以帮助我。例如：

  .controller('firstCtrl',function($scope){
   $scope.item = [{id:1, name:'John'},{id:2, name:'carter'},{id:3, name:'barsoom'},..]
   })
   .controller('secondCtrl',function($scope){
    $scope.jsondata = item;
    console.log(JSON.stringify($scope.jsondata));
   })

有可能吗？谁能帮帮我吗。谢谢。

Answer 1

如果要在控制器之间共享数据，则应使用Angular Services。它们是单例，旨在用于共享应用程序中的公共代码。因此，例如，放置$ http请求或许多地方使用的某些数据是一种很好的做法。

一些例子是：

https://jsfiddle.net/relferreira/2b5amcya/

JS：

<div data-ng-app="app">

  <div data-ng-controller="MainController as mainVm">
    {{mainVm.name}}
  </div>

  <div data-ng-controller="DetailController as detailVm">
    {{detailVm.name}}
    {{detailVm.other}}
  </div>

</div>

HTML：

 <body ng-app="myApp">

    <div ng-controller="ctrl">
        {{name}}

    </div>

    <div ng-controller="c">
        {{name}}

    </div>


</body>

var app = angular.module('myApp', []).controller('ctrl', ['$scope', '$rootScope', function ($scope, $rootScope) {

    $rootScope.name = "vipin";

}]).controller('c', ['$scope', '$rootScope', function ($scope) {


}])

Answer 2

试试这个

var app = angular.module('myApp', []).controller('ctrl', ['$scope', '$rootScope', function ($scope, $rootScope) {

        $rootScope.name = "vipin";
    }]).controller('c', ['$scope', '$rootScope', function ($scope) {


    }])

运行此代码，您可以在两个控制器中获取$ rootScope.name值

<body ng-app="myApp">    
    <div ng-controller="ctrl">
        {{name}}
    </div>

    <div ng-controller="c">
        {{name}}
    </div>
</body>

您可以使用事件广播或服务注入控制器。

方法1：

myApp.controller('FirstCtrl', function ($scope) {
    $scope.$broadcast('Test_Data',{ data: {} });
  })
myApp.controller('SecondCtrl', function ($scope) {
    $scope.$on('Test_Data', function(event, args) {
        var data= args.data
      // do something useful here;
    });
  });

方法2：

     myApp.factory('TestData', function () {
        var data = {};
            var setData=function(){...}
        return data;
      });
    myApp.controller('FirstCtrl', function ($scope, TestData) {
        $scope.data = TestData;
      })

从另一个访问一个控制器数据
