Push is not function Angularjs error

Question

$scope.post1 = angular.fromJson(window.localStorage['like'] || '{}');

  var like ={
    id:''+id
  };
  $scope.post1.push(like);

window.localStorage['like'] = angular.toJson( $scope.post1);

When I run this code it gives $scope.post1.push is not a function..How to solve this problem?

check the return type of window.localstorage. that should give you some clues. Use angular.isArray(window.localstorage['like']); — Incpetor

In case post1 not being an array isn´t the problem you could try to put a $timeout after reading from local storage. It could be a matter of race conditions. $timeout(function(){$scope.post1.push(like);},200); — 0xRLA

There is no push() function in javascript Object or String. But Array has it.

Maybe you could do something like this instead:

$scope.post1.like = { id: '' + id };

See https://docs.angularjs.org/api/ng/function/angular.fromJson for more information about angular.fromJson() return type.

Edit:

It seems like I misread something. Try this:

If you want to create array of object, you should pass array to angular.fromJson()
