你好，我正在使用youtube iframe嵌入式API。我想按用户跟踪搜索视频事件。请帮我如何追踪这个。
没有简单的方法可以单独使用api来跟踪事件。
您可以在间隔中运行一个javascript函数，并检查测量的时差是否与预期的不同
下面是一个示例代码：
<html>
<body>
<div id="player"></div>
<script>
var tag = document.createElement('script');
tag.src = "https://www.youtube.com/iframe_api";
var firstScriptTag = document.getElementsByTagName('script')[0];
firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);
var player;
function onYouTubeIframeAPIReady() {
console.log("ready");
player = new YT.Player('player', {
height: '390',
width: '640',
videoId: 'cRmNPE0HwE8',
events: {
'onReady': onPlayerReady,
'onStateChange': onPlayerStateChange
}
});
//console.log(player);
}
function onPlayerReady(event) {
event.target.playVideo();
/// Time tracking starting here
var lastTime = -1;
var interval = 1000;
var checkPlayerTime = function () {
if (lastTime != -1) {
if(player.getPlayerState() == YT.PlayerState.PLAYING ) {
var t = player.getCurrentTime();
//console.log(Math.abs(t - lastTime -1));
///expecting 1 second interval , with 500 ms margin
if (Math.abs(t - lastTime - 1) > 0.5) {
// there was a seek occuring
console.log("seek"); /// fire your event here !
}
}
}
lastTime = player.getCurrentTime();
setTimeout(checkPlayerTime, interval); /// repeat function call in 1 second
}
setTimeout(checkPlayerTime, interval); /// initial call delayed
}
function onPlayerStateChange(event) {
}
</script>
</body>
</html>
您可以简单地（无需定时器）：
<script>
const tag = document.createElement('script');
tag.src = "https://www.youtube.com/iframe_api";
const firstScriptTag = document.getElementsByTagName('script')[0];
firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);
let previousAction;
let previousTime;
function onYouTubeIframeAPIReady() {
player = new YT.Player('player', {
events: {
'onStateChange': onPlayerStateChange
}
});
}
function onPlayerStateChange({target, data}) {
if(data != 3) { // we don't need to detect buffering
return;
}
const currentTime = target.getCurrentTime();
// detect existing action and previous action which is not paused
if (!previousAction || previousAction != 2 ) {
// return existing youtube api data (-1 || 0 || 1 || 5 )
return data;
} else if (Math.abs(previousTime - currentTime) > 1 ) {
// we have Seek event and we have time when it was started(previousTime). Also we have finish time of Seek event(currentTime).
return 'Seek'
}
previousTime = currentTime;
previousAction = data
}
</script>
