Exploring a property within a JavaScript object

Within my code, I am working with an array of objects called user. When I try to log the first object using console.log(user[0]);, I receive this output:

Object {activityId: "2", id: "1", activityDt: "01/15/2016"}

Afterwards, I attempt to store user[0] in a separate object.

var p = user[0];

Subsequently, when I aim to retrieve the activityId property from the object, I use:

console.log(p.activityId);

Unexpectedly, nothing is being printed and an error occurs. Any suggestions would be greatly appreciated.

Snippet of my code:

 mainFactory.getUser()
  .success(function(usersData) {
      $scope.userData = usersData;

      // Determine which events we will show (remove certain events)

      var userActivity = [];
      angular.forEach($scope.userData, function (user, index){

        // console.log(user.length);

        //for(var i = 0; i<user.length; i++){
        //   console.log(user[i]);
        // }

        // console.log(user[0]);
        var p = user[0];
        console.log(p.activityId);

        // for (var key in p) {
        //   alert(p[key]);
        // }




      });
    })
    .error(function(err) {
      console.log('Error: ' + err);
    });

Error Message:

Answer №1

After utilizing the forEach method, you will be able to access each element of $scope.userData. Trying to treat users as an array will not yield the desired result and accessing user[0] will result in undefined, which is likely causing the error message you are seeing.

angular.forEach($scope.userData, function (user, index){
    var p = user;
    console.log(p.activityId);
