Using AngularJS to iterate through JSON data

I received JSON data from my Facebook account and saved it in a file called facebook.json.

Next step is to retrieve and process the data from the JSON file in my controller.

app.controller('Ctrl', function($scope, $http) {    

    $http({method: 'GET', url: 'facebook.json'}).success( function(data){
        $scope.info = data; // response data 
        });
           });

Here is the content of the JSON file:


{
  "id": "1011561500", 
  "name": "name surname", 
  "posts": {
    "data": [
      {
        "id": "108556200_10201961149445422", 
        ...
      </div>

I'm struggling with looping through the data to extract all posts' messages.

The current code successfully retrieves one element:

{{info.posts.data[5].message}}

I attempted to loop through the data like this:

<li ng-repeat="message in info.posts.data">
    {{message.posts.data[$index].posts}}
</li>

Answer №1

When utilizing ng-repeat with an array, there is no need to access the value using an index. The value will be copied into your temporary variable, allowing direct access without the use of $index within the ng-repeat.

This approach will work for you.

<li ng-repeat="val in info.posts.data">
    {{val.message}}
</li>

However, when iterating over an object and needing both keys and values, the following format can be used:

<li ng-repeat="(k,v) in anyObject">
    Key - {{k}}
    Value - {{v}}
</li>

Answer №2

Solution:

<li ng-repeat="element in data.posts.messages">
    {{element.content}}
</li>
