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，但我认为在javascript中全局变量可以使用。有谁能给我解决方案？感谢
更新
这是我用xhr获取API API中数据对象的响应
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';
};
});
});
这是我根据用户点击获取数据的HTML
<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>
这是来自按钮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

它确实工作正常，这是你尝试实现的working fiddle。这是一个包含您对象的fiddle。
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);
});
