Importing data from an external file into an array using AngularJS

Hey there, I'm new here on Stack and hoping someone can lend a hand because I've hit a roadblock!

I'm working with an AngularJS script that generates multiple icons using data from a simple array. Each icon is linked to a YouTube video.

The code snippet below shows how straightforward the array and function are:

app.controller('videolist', function ($scope, $http) {
$scope.videos = ['q_664lrmyGE','q_664lrmyGE','dWuEVSCw8B8','3Wm3G8s8bxk','_ppuCZR8Mkw','9gN_cmK9TUc','s7lVGhTPQAY','_rNmmHXEdTc','blr-qDffIq0','_70M4lkLKPk','wjB9JtTU7SU','BGh1xc-O0WA','uxEBK9q686c','ToO-tS-X2U4','AKrmrbCTNxc'];

$scope.icon = [];
  // add youtube videos
  for (i=0; i<$scope.videos.length; i++) {
    $scope.icon.push({id: $scope.videos[i], thumb: 'mqdefault'});

  }
});

Now my goal is to load the array from an external JSON file.

I've attempted various methods, but none seem to be successful. How can I achieve this? And what should the structure of the JSON file look like? Most examples I've come across have records with two or three values, often in a "label":"value" pair.

Any guidance would be greatly appreciated!!

Answer №1

If you have an array that is not valid JSON, you can solve this issue by embedding the array within a parent JSON object. Here's how:

var videos = {'videoArray':['q_664lrmyGE','q_664lrmyGE','dWuEVSCw8B8',...]}

To access the contents of the array, simply reference videos.videoArray

Answer №2

Working with JSON

Understanding the structure of JSON format is crucial, as pointed out by Disperse in the example code

$scope.videos = {'keyToArray':['foo','bar','baz',]}
. It's worth considering using var instead of $scope. for variables that don't need to be accessed globally, especially when processing data within a function.

Importing Data from External Files

If you're looking to retrieve data from a .json file, utilizing the unused $http service can help. Try the following approach:

$http.get("video.json").then(function (response) {
    $scope.videos = response.data;
});

Hopefully, this solution proves helpful for your task!
