我想在用户收听音频元素超过5秒时记录。如何使用HTML5检测到这一点?

我会处理播放事件,然后在完成后使用setTimeout调用轨道。像这样的东西(伪代码):
var timeHandler = null;
// if they stop listening, don't give them the alert
myAudioElement.addEventListener('stop', function() {
if (timeHandler) clearTimeout(timeHandle);
});
// when they start to play, set an event to pop up 5 seconds later
myAudioElement.addEventListener('play', function() {
timeHandler = setTimeout(5000,function() {
// here I would make some kind of ajax call to log the event
alert("it's been 5 seconds!");
});
与往常一样,根据您的需求,这可能会变得更加复杂。您也可以使用ontimeupdate事件来跟踪播放头当前所在的位置。有关html5音频事件的参考,请查看此页面:
