问题与iOS的HTML5音频元素的持续时间值 [英] Problem with duration value of HTML5 audio element in iOs

问题描述

我在开发iOS设备的web应用程序，但我有一个HTML5的音频标签的问题...
我设计了一个自定义的音频播放器，我管这首歌用JavaScript函数。
Safari浏览器的桌面应用程序运作良好，但在Safari移动不承认的音频的持续时间;持续时间属性的值是NaN。
我要玩，停止和回放音频检索正确的值。
可能的原因是，媒体preLOAD是在移动Safari浏览器禁用了...
有没有一种方法来读取第一枪正确的价值？

I'm developing a web app for iOs device, but I have a problem with the html5 audio tag... I designed a custom audio player, and I control the song with javascript functions. With safari desktop the app works well, but on safari mobile it doesn't recognize the duration of the audio; the value of the duration property is NaN. I have to play, stop and replay the audio for retrieve the correct value. Probably the cause is that the media preload is disabled on safari mobile... Is there a way to read the correct value at the first shot?
