Global Variable Can't Use in Angular.foreach

Question

I have a problem, my global variable can't use on outside when i use angular.foreach, but i think in javascript global variable can use. Anybody can give me solution ? Thanks

UPDATE

This is my xhr to get response from data object in API

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';
                };
            });
        });

This is my HTML to GET DATA BASED ON USER CLICK

<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>

This is my code from button getData() :

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

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

    console.log(a);
};

This is my data object

What global variable? How is that related to Angular? What Angular version are you using? Where do you have this code? — Günter Zöchbauer
– Günter Zöchbauer, Commented Feb 16, 2017 at 10:04
@GünterZöchbauer the var a, its related to javascript as he scoped in the tags, the version is not important here, he "have" this code here. Its mug to asking that kind of question snake. Its legal question for Stackoverflow and we all started at some point. — lin
– lin, Commented Feb 16, 2017 at 10:09
@echonax Take a look at the tags, no "Angular" tag over here, just "AngularJS". Its pretty clear what he is asking. — lin
– lin, Commented Feb 16, 2017 at 10:11
Could you please elaborate on what's not working? What is your expected output? This should work, but a will always have the last data.tag's value, as you overwrite it in each iteration of the forEach loop, and only log it to the console after that. — Alex Szabo

It does work fine, here is a working fiddle of what you try to achieve. Here is a fiddle including your object.

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);
});

userpr Over a year ago

where I can put data.tags ? because from data.tags , my label can output value

userpr Over a year ago

actually , i edited your code "label : 'test'" to "label : data.tags" but still not working

lin Over a year ago

@PriskilaNovia you could make it a global var if you need it in some other function inside your application or declaring it as a function var inside your controller. Its depending on where you need it. I updated my answer.

userpr Over a year ago

The output in console is [Object, Object, Object, Object, Object, Object, Object] even though the code a= item.label. Im confused

lin Over a year ago

@PriskilaNovia please compare your data object structure with mine or update my fiddle to reproduce your problem. Please post that fiddle here in the comments.
