Functions in Controllers with Angular js

Question

I am having an issue getting the HTMLAudioElement to work in my angular.js application. I am using a controller to push the function to my play button but the click is unresponsive. I have the function inside of the ng-click directive as playpause() but it still is not responsive. I have no errors when my code runs. Any ideas?

Here is my controller code:

angular.module('MainCtrl', []).controller('MainController', function($scope) {

$scope.audio = new Audio('../../data/mp3/pound.mp3');
            $scope.currentNum = 0;

            // tell audio element to play/pause, you can use $scope.audio.play()
            $scope.playpause = function(){return $scope.audio.play();};
   });

and here is my html:

 <!doctype html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <base href="/">

If you want to execute $scope.audio.play you could do this<span id="play" ng-click="audio.play()" class="fa fa-play fa-4x"></span> — klode

I strongly not recommend to put an audio file into the $scope. Just store the audio reference in your directive like:

var myAudio = new Audio('../../data/mp3/pound.mp3');
$scope.play = function(){
  myAudio.play();
};

I wrote "play" not "playpause", because audio.play is not a toggle function, so you need to write your own pause for this. also I have to mention that, you should make a directive for this, then pass in, which file the directive should play

I noticed you changed the name. Added ng-click="play()" and it still does not work. Am I missing something here? I do plan to move to a directive but I wanted to get simple functionality working at least.

This works so there must be a problem with where I am pointing to the media file! Thanks a bunch sir!
