为什么我的声音复卷？ [英] Why isn't my audio rewinding?

问题描述

我有一个有点麻烦，在Javascript复卷音频。我基本上有蜂鸣每一秒，因为它朝倒计时结束得到了倒计时。

I'm having a bit of trouble rewinding audio in Javascript. I basically have a countdown that beeps each second as it gets towards the end of the countdown.

我试着用;

var bip = new Audio("http://www.soundjay.com/button/beep-7.wav");
bip.play();

但它没有哔每一秒，我猜有事可做withit无需加载新的声音每一秒。然后，我尝试从外部加载声音，并与下面code触发它。

but it didn't beep every second which I'm guessing has something to do withit having to load a new sound every second. I then tried loading the sound externally and triggering it with the following code.

bip.pause();
bip.currentTime = 0;
console.log(bip.currentTime);
bip.play();

但这只是播放的声音再一次完全不能倒带（这是由控制台登录0.19秒的时间第一次通关后显示）。

but this only plays the sound once then completely fails to rewind it (this is shown by the console logging a time of 0.19 seconds after the first playthrough).

有我丢失的东西在这里？

Is there something I'm missing here?

推荐答案

在谷歌浏览器，我注意到它只有当你有在同一个域中的音频文件的工作。我没有问题，如果音频文件是在同一个域中。事件设置 .currentTime 和

In google chrome I noticed that it only works if you have the audio file in same domain. I have no problems if the audio file is in same domain. Event setting .currentTime works.

跨域：

var bip = new Audio("http://www.soundjay.com/button/beep-7.wav");
bip.play();
bip.currentTime; //0.10950099676847458
bip.currentTime = 0;
bip.currentTime; //0.10950099676847458

同域：

var bip = new Audio("beep-7.wav");
bip.play();
bip.currentTime; //0.10950099676847458
bip.currentTime = 0;
bip.currentTime; //0

我试着在Google上搜寻了一​​会儿，能找到什么在这个甚至任何讨论规格。

I tried googling for a while and could find nothing in specs about this or even any discussion.
