Question

我试图暂停视频然后恢复播放。但我认为我不知何故需要清除暂停功能？我已经尝试了myVideo.play（）的迭代，我可以让它发挥，但只是短暂的爆发。任何帮助都会受到欢迎。

var myVideo = document.getElementById("video1");

myVideo.addEventListener("timeupdate", function(){
    if(this.currentTime >= 1 * 2) {
        this.pause();
    }
});

如果我理解正确，您希望您的事件监听器只触发一次（所以当您下次播放视频时，它不会立即再次暂停）。如果是这样，请试一试：

var myVideo = document.getElementById("video1");

// Give this function a name so we can refer to it later.
function pauseOnce() {
   if (this.currentTime >= 1 * 2) {
       this.pause();

       // Our work is done. Remove the event listener. (We need a reference to
       // the function here.)
       this.removeEventListener("timeupdate", pauseOnce);
   }
}

myVideo.addEventListener("timeupdate", pauseOnce);

在JavaScript / HTML5中暂停后恢复视频播放？
