我有一个问题，当我使用angular.foreach时，我的全局变量不能在外面使用，但是我认为可以在javascript中使用全局变量。有人可以给我解决方案吗？谢谢

这是我从API中的数据对象获取响应的xhr

HttpService("POST", url, param, function(response){

            $scope.parsing = angular.fromJson(response.data);

            $scope.result = {};

            angular.forEach($scope.parsing, function(item){

                $scope.result[item._id] =  item;

                $scope.getInclude = function(){
                    return 'templates/table.html';
                };
            });
        });

这是我的HTML，可根据用户点击获取数据

<tbody ng-repeat="data in result">
<tr>
<td width="20%">
<button type="button" class="btn btn-primary" ng-click="getData(data)"><i class="fa fa-edit"></i> Edit</button>
<button type="button" class="btn btn-danger"><i class="fa fa-trash"></i> </td>
</tr>
</tbody>

这是我的按钮getData（）的代码：

$scope.getData = function(data) {
    var a;

    angular.forEach(data.tags, function(item){     
        a = item.label;
    });

    console.log(a);
};

这是我的数据对象

它做工精细，这里是工作提琴的你试图达到的目标。这是一个包括您的对象在内的小提琴。

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

myApp.controller('MyCtrl', function ($scope) {

    var data = [
        {
          label: 'test'
        },
        {
          label: 'test2'
        }
    ];

    angular.forEach(data, function(item){     
        a.push(item.label);
    });

    console.log(a);
});
