        )

Please I would like to know how to parse (the codehttp field) in javascript the final json variable. I would like to do it into an angularjs controller.

I have tried this code (in a controller) but it does'nt work

$scope.flag_a = 'good';

for(var key in $scope.content.codehttp)
{
        if($scope.content.codehttp[key] != '200')
        {
                $scope.flag_a = 'bad';
        }
}

• javascript
• arrays
• angularjs

• 4 for...in loops are meant for objects, not for arrays, use for(i=0;i<$scope.content.codehttp.length;++i) for an array – Elias Van Ootegem Commented Sep 17, 2014 at 8:28

At first you need to make sure, your response actually is treated as JSON (thus results in a proper javascript object), and then you can use on of the following three ways:

Using angularjs's own method angular.forEach

$scope.content = {};
$scope.content.codehttp = [200, 200, 200, 201];

angular.forEach($scope.content.codehttp, function(value, key) {
  if (value != 200) {
    $scope.flag_a = 'bad';
  }
})

Using a plain 'for' loop:

for(i=0;i<$scope.content.codehttp.length;i++) { 
  if ($scope.content.codehttp[i] != 200) {
    $scope.flag_a = 'bad';
  }
}

Using the (relatively new) native Array.prototype.forEach method:

$scope = {};
$scope.content = {};
$scope.content.codehttp = [200, 200, 200, 201];

$scope.content.codehttp.forEach(function(value, key) {
    if (value != 200) {
        // for demonstrational purposes only:
        document.write("Entry #"+(key+1)+" contained a bad status: "+value);
        $scope.flag_a = 'bad';
    }
})
