Javascript，变量不能通过函数来访问 [英] Javascript, Variable is not accesible by function
问题描述
我制作了一个phonegap应用程序，当用户点击按钮时播放声音：
I made an phonegap application that plays an sound when the user clicks on the button:
<button onclick="playAudio('test.mp3')">Play Some Audio</button>
但我想声音停止，当用户做doubleclick，不知何故我的代码不工作！ Im是一个初学者在javascript，并认为我did not把变量=媒体在正确的位置。这是我的完整代码：
But i want that the sound stops when the user makes an doubleclick, somehow my code dont works! Im an beginner in javascript, and think the i didnt put the variable = media in the right position. Here is my full code:
<body>
<h1>Playing Audio</h1>
<button onclick="playAudio('test.mp3')">Play Some Audio</button>
<script type="text/javascript" src="cordova-2.4.0.js"></script>
<script type="text/javascript" src="js/index.js"></script>
<script type="text/javascript">
app.initialize();
var playing = false;
var media = null;
function playAudio(src) {
if (!playing) {
if (device.platform == 'Android') {
src = '/android_asset/' + src;
}
var media = new Media(src);
media.play();
playing = true;
} else {
media.stop();
playing = false;
}
}
</script>
</body>
推荐答案
现在我发现了问题， p>
Now i found the problem, you cannot use
media = new Media (src)
而不是我有tu使用
my_Media = new Media (src)
与媒体一词有一个相互关系！
但是@Alexandre说的是absolutley正确，这让我最后的结果！
感谢
There is an interreference with the word media! But what @Alexandre said was absolutley correct, and that brougt me to the final result! Thanks
