獲取當(dāng)前時(shí)間戳的三種方法：

        var myDate = new  Date(); //獲取當(dāng)前時(shí)間
        var minS = myDate.getTime();
        var minS2 = myDate.valueOf();
        console.log(+ myDate);
        console.log(minS);
        console.log(minS2);

獲取當(dāng)前時(shí)間的年月日時(shí)分秒：

        //1.創(chuàng)建當(dāng)前的時(shí)間
        var myDate = new  Date();
        //2.獲取當(dāng)前的年
        var year = myDate.getFullYear();
        //2.1獲取月份,月份是從0到11,0表示一月
        var month = myDate.getMonth();
        //2.2獲取日
        var day = myDate.getDate();
        //2.3獲取星期對(duì)應(yīng)的序號(hào),0表示星期日,1表示星期一,一次類推
        var weekDay = myDate.getDay();
        //2.4獲取小時(shí)
        var hour = myDate.getHours();
        //2.5.獲取分鐘
        var min = myDate.getMinutes();
        //2.6獲取秒數(shù)
        var sec = myDate.getSeconds();
        //2.7獲取毫秒數(shù)
        var minS = myDate.getMilliseconds();
