刷网上学习时网页弹窗怎么关闭，

//使用事件监听方式捕捉事件
video.addEventListener("timeupdate",function(){
var timeDisplay;
//用秒数来显示当前播放进度
timeDisplay = Math.floor(video.currentTime);

//当视频播放到 4s的时候做处理
if(dialogCounts[0] == timeDisplay){
    if(flagTime){
        tempRecord("auto");
        returnConfirm();
        closePage();
        //此处只判断整数
        flagTime = false;
    }else{
        return false;
    }
}  
if(dialogCounts[1] == timeDisplay){

    }else{
