javascript - 从addEventListener()调用函数

我有下一个代码，我无法调用ShowMedalMessage()函数

var totalsounds = 3;
var currentsound = 1;
var audioElement = document.createElement('audio');
audioElement.setAttribute('src', 'notify.wav');
audioElement.setAttribute('autoplay', 'autoplay');
audioElement.addEventListener('ended', function() {
    if (currentsound < totalsounds) {
        this.currentTime = 0;
        this.play();
        currentsound = currentsound + 1;
    }
    ShowMedalMessage(1);
}, false);​

如果对该函数的调用在audioElement.addEventListener之前，则它将正确调用，但如果行ShowMedalMessage(1);在里面，它不起作用:(

谢谢!

最佳答案

这在Chrome和Firefox中对我有用。

Hese是现场example

function showMessage() {
  document.write("Sound played");
}

var totalsounds = 3;
var currentsound = 1;
var audioElement = document.createElement('audio');
audioElement.setAttribute('src', 'http://www.wav-sounds.com/cartoon/bugsbunny1.wav');
audioElement.setAttribute('autoplay', 'autoplay');
audioElement.addEventListener('ended', function() {
    if (currentsound < totalsounds) {
        this.currentTime = 0;
        this.play();
        currentsound = currentsound + 1;
    }
    showMessage();
}, false);

document.body.appendChild(audioElement);
