Hello i have two similar code. One is working, the other one does not work.

Below is working code :

<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
    <title>Welcome in the AngularJS</title>
    <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.2/angular.min.js"></script>
</head>
<body ng-app="app">
    <div ng-controller="forEachController">
        <p ng-repeat="pr in prop">Properties: {{pr}}</p>
        <p ng-repeat="vl in val">Value: {{vl}}</p>
        {{obj}}
    </div>
</body>
</html>
<script>
    var app = angular.module("app", []);
    app.controller('forEachController', ['$scope', function ($scope) {
        $scope.prop = [];
        $scope.val = [];
        $scope.obj = [];
        angular.forEach([{ name: 'Todd', location: 'UK' },{ name: 'Todd', location: 'UK' }], function (value, prop, obj) {
            $scope.val.push(value);
            $scope.prop.push(prop);
            $scope.obj.push(obj);
        });
    }]);

</script>

Below does not work. I couldn't solve it. How could i fix that and get a similar result with the above working code?

<!DOCTYPE html>  
<html ng-app="" xmlns="http://www.w3.org/1999/xhtml">    
<head>  <!-- www.techstrikers.com -->  
	<title>My first AngularJS code</title>    
		<script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.4.5/angular.min.js"></script>
</head>    
	<body bgcolor="#bnde45">  
		 
			 
			<script>    
			
			angular.forEach([{ name: 'Todd', location: 'UK' },{ name: 'Todd', location: 'UK' }], function (value, prop, obj) {
				document.write(value);
				document.write(prop);
				document.write(obj);
			});
			</script>  
		
	</body>    
</html>

I'm wondering why that does not work. Because everything looks like fine..

Hi Ömer,

you can't use document.write in this fashion. It will probably just fail silently (seem to do nothing)

Regards

OK, one question more : what is obj? Does it refer to the first param of angular.foreach() method?

hi Ömer,

Well, as you can clearly read in the first paragraph of the forEach documentation, it is indeed!
