AngularJS scope inside a for loop

Question

var coutas = [];

  for (var i = 0; i < d.length; i++) {
    coutas.push(JSON.parse(d[i].coutas));
  }

 for (var i = 0; i < coutas.length; i++) {
    $scope.coutas = coutas[i];
 }

That doesn't work

what I try to do is assign the variable coutas the scope.coutas

i'm using two for loop because that :

the firt loop , It is to tour the first array, and the second loop is to tour the seconds array

example : the firts loop tour the array 0 but inside the array 9 they are 22 objets.

i want that :

Why are you using the second for loop? Why do you not do so $scope.coutas = coutas? — Dmitriy

Also your $scope.coutas will only grab the last value in the array. if you are planning to store the entire array then just assign $scope.coutas = coutas like @DmitriyLoskutov suggested. — dishwasherWithProgrammingSkill

you can use $scope.coutas.push() so no need to use second for loop — Shaishab Roy

You should describe your question clearly. what your data and what do you want? also can you create plunker demo using demo data ? — Shaishab Roy

Instead of using two for loop you may solve this problem using single loop. In your solution you generate coutas array in first loop then in second loop assigned only last info of var coutas in angular variable not whole coutas.

One process can be assign whole coutas after first loop.

like:

$scope.coutas = coutas

or you can push in $scope.coutas in first loop.

like:

for (var i = 0; i < d.length; i++) {
    $scope.coutas.push(d[i].coutas); // if need to parse then use JSON.parse(d[i].coutas)
}

No need to require two loop ,if u did then define $scope.coutas =[ ] and push the arrar of every looping item;

   var coutas = [];

  for (var i = 0; i < d.length; i++) {
    coutas.push(JSON.parse(d[i].coutas));
  }
$scope.coutas =[];
 for (var i = 0; i < coutas.length; i++) {
    $scope.coutas.push(coutas[i]);
 }
