Question

Utilize the $scope variable as a JSON object for interacting with the $http service

Is there a way to extract all the data from Angular's scope service without creating an additional object? I am trying to send everything on the scope to a server using $http.post, but it seems that $scope is a circular structure, resulting in "Converting circular structure to JSON" error. Is there a workaround for this?

Currently, I am using a hack involving Underscore and Underscore.string as follows:

var toJs = function(item) {
  var obj = {};
  _.each(item, function(val, key) {
    if (!_s.startsWith(key,'$')) {
      obj[key] = val;
    }
  });
  return obj;
};

Then simply pass:

toJs($scope)

javascript angularjs

Avoid creating a brand-new object by deleting the circular reference and any unnecessary properties from $scope, converting it to JSON using the toJson method, and then re-adding the previously removed properties back to $scope.

Take the $scope object and nest a child property inside, then use the toJson function on that nested property.

<input ng-model='username'>

should be updated to

<input ng-model='user.username'>

in order to execute

$http.post('/url', angular.toJson($scope.user));
