我知道这是不明智的。但仍需要实现此功能。尝试了从onseeking,onseeked到媒体控制器的所有功能。什么都不管用。是否有要禁用查找的外部库。如果有一些关于如何使用自定义控件的指针,将很有帮助。

这个问题很老了,但仍然很重要,所以我的解决方案是:

var video = document.getElementById('video');
var supposedCurrentTime = 0;
video.addEventListener('timeupdate', function() {
  if (!video.seeking) {
        supposedCurrentTime = video.currentTime;
  }
});
// prevent user from seeking
video.addEventListener('seeking', function() {
  // guard agains infinite recursion:
  // user seeks, seeking is fired, currentTime is modified, seeking is fired, current time is modified, ....
  var delta = video.currentTime - supposedCurrentTime;
  if (Math.abs(delta) > 0.01) {
    console.log("Seeking is disabled");
    video.currentTime = supposedCurrentTime;
  }
});
// delete the following event handler if rewind is not required
video.addEventListener('ended', function() {
  // reset state in order to allow for rewind
    supposedCurrentTime = 0;
});

它与玩家无关,即使显示默认控件也能工作,即使在控制台中键入代码也无法绕过它。

从@svetlin-mladenov扩展答案,您可以执行以下操作以防止用户查找尚未观看的视频的任何部分。这还将允许用户倒带并找出先前已经观看的视频的任何部分。

var timeTracking = {
    watchedTime: 0,
    currentTime: 0
};
var lastUpdated = 'currentTime';

video.addEventListener('timeupdate', function () {
    if (!video.seeking) {
        if (video.currentTime > timeTracking.watchedTime) {
            timeTracking.watchedTime = video.currentTime;
            lastUpdated = 'watchedTime';
        }
        //tracking time updated  after user rewinds
        else {
            timeTracking.currentTime = video.currentTime;
            lastUpdated = 'currentTime';
        }
    }

});
// prevent user from seeking
video.addEventListener('seeking', function () {
    // guard against infinite recursion:
    // user seeks, seeking is fired, currentTime is modified, seeking is fired, current time is modified, ....
    var delta = video.currentTime - timeTracking.watchedTime;
    if (delta > 0) {
        video.pause();
        //play back from where the user started seeking after rewind or without rewind
        video.currentTime = timeTracking[lastUpdated];
        video.play();
    }
});

Did the trick for me :)

也许可以帮助到别人,我用这种方法去掉了所有的进度控制回调。

player.controlBar.progressControl.off();
player.controlBar.progressControl.seekBar.off();

var supposedCurrentTime = 0;

$("video").on("timeupdate", function () {

    if (!this.seeking) {
        supposedCurrentTime = this.currentTime;
    }
});
// prevent user from seeking
$("video").on('seeking', function () {
    // guard agains infinite recursion:
    // user seeks, seeking is fired, currentTime is modified, seeking is fired, current time is modified, ....
    var delta = this.currentTime - supposedCurrentTime;

    if (Math.abs(delta) > 0.01) {
        //console.log("Seeking is disabled");
        this.currentTime = supposedCurrentTime;
    }

});

$("video").on("ended", function () {
    // reset state in order to allow for rewind
    supposedCurrentTime = 0;
});

假设这是一个标准的HTML5视频播放器,没有第三方JS库的干扰:
这应该会阻止他们死在他们的轨道上,虽然晚了十多年才满足你的需要,但对别人仍然有用...

V.onseeking = function () {
    event.preventDefault();
    alert('Please don\'t skip the tute!');
};

注:“V”是玩家的ID。

要隐藏所有视频控件,请使用此-

document.getElementById("myVideo").controls = false;

你可以使用一个HTML5视频播放器,比如video.js,并使用CSS来隐藏搜索栏。
或者你可以build your own controls为HTML5视频。
此外,您正在寻找的事件是“寻找”。如(使用新的jquery事件绑定):

$(myVideoElement).on('seeking', function () {
    // do something to stop seeking
})

使用video js作为我的视频播放器,而不是vanilla HTML5版本:

.vjs-default-skin .vjs-progress-holder {
  height: 100%;
  pointer-events: none;
}
