Retrieving a dynamic JSON object for the MusicBrainz application using AngularJS

I want to incorporate a search form into my application that sends the form result to the specified link. I am retrieving artist names from the musicbrainz JSON database using the following request: "NAME OF AN ARTIST"%20e*&fmt=json

The "NAME OF AN ARTIST" is the input that I want to submit through the form. I am new to angular and struggling to understand how to achieve this despite researching online.

Below is the search form:

<form ng-submit="search()" name="nomartiste">
  <label>Search:
    <input type="text" ng-model="nom"/>
    <input type="submit" value="Search"></input>
  </label>
</form>

Here is the JavaScript code:

function Artist($scope)
{    
    $scope.nom = 'Muse';
    $scope.search = function()
    {
        var url = "http://search.musicbrainz.org/ws/2/artist/?query=" + $scope.nom + "%20e*&fmt=json";

        $http.get(url)
            .then(function(response)
        {
            $scope.artistNames = response.data;
            console.log($scope.artistNames);
        })
    }
}

The request results, based on the input from $scope.nom in the form, should be displayed. However, no data is showing up in the console log, not even the Json tree.

Answer №1

I see that you are looking to showcase the outcome of executing your queries. You initiated an http.get request that yielded a JSON object labeled as response. However, you encountered an error when trying to access data that does not exist.

Simply delete 'data' from 'response.data'

Answer №2

Upon visiting the URL provided, I encountered a response stating

No 'Access-Control-Allow-Origin' header
. It is possible that your browser's console is not displaying this message for some reason.

According to the documentation of their web service, the correct URL to search for an artist should be constructed like this: .

It's worth noting that I made a modification to this line:

$scope.listenoms = response.data.artists;

var app = angular.module("app", []);

app.controller("controller", function($scope, $http) {
  $scope.nom = "Muse";

  $scope.search = function() {
    var url = "http://musicbrainz.org/ws/2/artist/?query=artist:" + $scope.nom + "&fmt=json";

    $http.get(url)
      .then(function(response) {
        $scope.listenoms = response.data.artists;
        console.log($scope.listenoms);
      });
  };
});
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.5.0/angular.min.js"></script>
<div ng-app="app" ng-controller="controller">
  <form ng-submit="search()" name="nomartiste">
    <label>Rechercher:
      <input type="text" ng-model="nom" />
      <input type="submit" value="Rechercher"></input>
    </label>
  </form>

  <table>
    <thead>
      <tr>
        <th>Name</th>
        <th>Country</th>
        <th>Disambiguation</th>
      </tr>
    </thead>
    <tbody>
      <tr ng-repeat="artist in listenoms">
        <td>{{artist.name}}</td>
        <td>{{artist.country}}</td>
        <td>{{artist.disambiguation}}</td>
      </tr>
    </tbody>
  </table>
</div>
