What is the mechanism for handling click events in AngularJS?

Upon receiving JSON data on my webpage, I want to enable "like" and "dislike" options for buttons with a click event implemented through the code snippet below.

However, I am encountering difficulties in achieving the desired outcome and am unsure of how to properly iterate through the array.

// Implementation of like and dislike buttons

$scope.like = function(episode){
                    episode.cue.episode.ratings.loved = 
                    (episode.cue.episode.ratings.loved) + 1;
                    if ((episode.cue.episode.ratings.hated) > 0)
                        episode.cue.episode.ratings.hated = 
                        (episode.cue.episode.ratings.hated) - 1;
                    episode.liked = true;
                    episode.disliked = false;
                };

Answer №1

You are encountering 2 issues with the code that have straightforward solutions.

  1. The button is attempting to pass episod which is not a recognized variable within the object. Instead, try using 

    ng-click="likeme(tvshow.episode)"

  2. The function that is receiving the data is searching through a tree for an episode without being provided with the tree. It only needs information about the episode. Replace 

    parseInt(episod.tvshow.episode.ratings.loved)
    with parseInt(episod.ratings.loved)

EDIT

I have made changes to your code [here][1]. Please observe the adjustments made to the function and HTML. Ensure that the episode is passed to the function, and operations are performed only on the episode within the function.
