What is the best way to save an angular.js model variable into a regular javascript variable?

Is there a way for me to store the selected song artist in a variable within my JavaScript code? I need to have this value stored so that I can use it as a search term in another function. The expression {{selectedSong.artist}} returns a name, and I would like to save this name in a JavaScript variable.


    <div class="list-group-item col-md-12">
      <div class="col-md-6">
         <p>
            Title: <select ng-model="selectedSong" ng-options="song as song.title for song in songs.tracks"></select>
         </p>
         <p>
            Artist: <select ng-model="selectedSong" ng-options="song as song.artist.name for song in songs.tracks"></select>
         </p>
         <p>
            Time: <select ng-model="selectedSong" ng-options="song as (song.played_at | date: 'hh:mm') for song in songs.tracks">
             </select>
         </p>
      </div>
      <div class="col-md-6">
         <button class="btn-success btn-lg" ng-click="selectedSong = songs.tracks[0]">Now playing</button>
      </div>
    </div>
  

Answer №1

Once selectedSong is stored in your controller (assuming there is a controller above this code), you can utilize a $watch function to retrieve that variable whenever it changes, or simply access it directly from your controller.

Here is an example of using $watch:

$scope.$watch('selectedSong', function (newVal, oldVal) {
   if (newVal !== oldVal) {
      // Perform actions based on newVal, which will be the selectedSong
   }
});

Alternatively, you can reference it like this:

$scope.selectedSong
