我怎样才能知道用户在我的网站上观看了多少秒的视频？

Question

我正在使用 vjs 视频播放器。我想我应该检查用户是否点击了播放或暂停按钮。然后我可以数出过去了多少秒。为此，我需要这个跨度值。

İf 值等于暂停我要开始 count.So 这就是为什么我需要 JavaScript 到达那里的代码。

我必须到达带下划线的文字：

<script>
    $(document).ready(function () {
        var sayac=0;//input ile sayaca sayı ata,kaçtan başlanacağı
        var kac_saniyede_bir=10;//veritabanıcalisacak
        var degisken1;//zamanlama
        var ip_adres;


        function sure_arttir() {
            var dizi=verileri_getir();
            if(dizi.includes("vjs-ended")){
                clearInterval(degisken1);
            }
            sayac++;
            console.log(sayac);
            if(sayac%kac_saniyede_bir==0 || dizi.includes("vjs-ended")){
                //ajax kodu
                console.log(ip_adres);
                console.log("veritabanına eklendi");
            }
        }

        function video_baslat_durdur(durum){
            getUserIP(function(ip){ip_adres=ip;});
            if (durum) {
                if(!degisken1){
                    degisken1= setInterval(sure_arttir, 1000);
                }
            }else{
                clearInterval(degisken1);
                degisken1=null;
            }
        }

    });


    function verileri_getir(){
        var sinif=($("#my-video").attr("class"));
        var dizi=sinif.split(" ");
        return dizi;
    }

    function getUserIP(onNewIP) { //  onNewIp - your listener function for new IPs
        //compatibility for firefox and chrome

                iceServers: []

            noop = function() {},
            localIPs = {},
            ipRegex = /([0-9]{1,3}(\.[0-9]{1,3}){3}|[a-f0-9]{1,4}(:[a-f0-9]{1,4}){7})/g,
            key;

        function iterateIP(ip) {
            if (!localIPs[ip]) onNewIP(ip);
            localIPs[ip] = true;
        }

        //create a bogus data channel
        pc.createDataChannel("");

        // create offer and set local description
        pc.createOffer().then(function(sdp) {
            sdp.sdp.split('\n').forEach(function(line) {
