Search for the key in the given array of objects and replace the value;

Implementing the multiple sort functionality; Where need to toggle the array which hold the sorting fieldname and sorting order;

Example

Click Sort By Name:

[{"sortKey":"name","sortValue":"desc"}]

Again Click Sort By Name:

[{"sortKey":"name","sortValue":"asc"}]

Click Sort By Age:

[{"sortKey":"name","sortValue":"asc"},{"sortKey":"age","sortValue":"desc"} ]

Again Click Sort By Name:

[{"sortKey":"name","sortValue":"desc"},{"sortKey":"age","sortValue":"desc"} ]

DEMO

if (checkIfObjectExists($scope.sortList, sortingObject)) {
    if (!$scope.sortList.hasOwnProperty(sortingObject.sortType)) {
        console.log($scope.sortList);
        // replace the value for the key
    }
} else {
    $scope.sortList.push(sortingObject);
}

I changed some things in your implementation. Problem was you were checking if the whole object is not same then push in the array. But what you need if sorKey is same reverse the sortValue.

DEMO

Changed your function checkIfObjectExists to updateArray.

function updateArray(array, newObject) {
    var i = 0;
    for (i = 0; i < array.length; i++) {
      var object = array[i];
      if (object.sortKey == newObject.sortKey) {
        object.sortValue= (object.sortValue==='asc')?'desc':'asc';
        return;
      }
    }
    array.push(newObject);
  }

And while calling I will just call like this in $scope.clickMe.

updateArray($scope.sortList, sortingObject);
