利用三元运算符生成当前日期：年-月-日

        function getCurdate(){
            var myDate = new Date();
            var nowDateTime = myDate.getFullYear();
            nowDateTime = nowDateTime + ((myDate.getMonth() + 1) < 10 ? "-0" + (myDate.getMonth() + 1) : "-" + (myDate.getMonth() + 1));
            nowDateTime = nowDateTime + (myDate.getDate() < 10 ? "-0" + myDate.getDate() : "-" + myDate.getDate());
            return nowDateTime;
        }
        console.log(getCurdate());
