有谁知道我如何检查视频是否完全被观看？
我正在使用 html5视频播放器：
我正在使用 html5视频播放器：
<video width="480" height="400" controls="true" poster="">
<source type="video/mp4" src="video.mp4"></source>
</video>
解决方法
基本检查很简单,等待结束事件.这很简单,你可以谷歌吧.
现在要检查用户是否播放了完整视频,需要进行广泛的分析,检查他是否每次都播放.然而,这不是必需的,用户应该足够了：
>播放视频很长的秒数
>播放到视频结束
这个片段正是如此.如果您只是跳到最后,视频将不会被标记为完全播放.一遍又一遍地开始也不会标记它完全播放：
var video = document.getElementById("video");
var timeStarted = -1;
var timePlayed = 0;
var duration = 0;
// If video Metadata is laoded get duration
if(video.readyState > 0)
getDuration.call(video);
//If Metadata not loaded,use event to get it
else
{
video.addEventListener('loadedMetadata',getDuration);
}
// remember time user started the video
function videoStartedplaying() {
timeStarted = new Date().getTime()/1000;
}
function videoStoppedplaying(event) {
// Start time less then zero means stop event was fired vidout start event
if(timeStarted>0) {
var playedFor = new Date().getTime()/1000 - timeStarted;
timeStarted = -1;
// add the new ammount of seconds played
timePlayed+=playedFor;
}
document.getElementById("played").innerHTML = Math.round(timePlayed)+"";
// Count as complete only if end of video was reached
if(timePlayed>=duration && event.type=="ended") {
document.getElementById("status").className="complete";
}
}
function getDuration() {
duration = video.duration;
document.getElementById("duration").appendChild(new Text(Math.round(duration)+""));
console.log("Duration: ",duration);
}
video.addEventListener("play",videoStartedplaying);
video.addEventListener("playing",videoStartedplaying);
video.addEventListener("ended",videoStoppedplaying);
video.addEventListener("pause",videoStoppedplaying);
#status span.status {
display: none;
font-weight: bold;
}
span.status.complete {
color: green;
}
span.status.incomplete {
color: red;
}
#status.complete span.status.complete {
display: inline;
}
#status.incomplete span.status.incomplete {
display: inline;
}
<video width="200" controls="true" poster="" id="video">
<source type="video/mp4" src="http://www.w3schools.com/html/mov_bbb.mp4"></source>
</video>
<div id="status" class="incomplete">
<span>Play status: </span>
<span class="status complete">COMPLETE</span>
<span class="status incomplete">INCOMPLETE</span>
<br />
</div>
<div>
<span id="played">0</span> seconds out of
<span id="duration"></span> seconds. (only updates when the video pauses)
</div>

然后,您可以将其连接到Google Analytics,以查看有多少视频用户播放.来自google analytics website的简单代码：
ga('send','event','Videos','play','Video name');
