js实现日期格式20180102

日期格式为20180204：即为小于10的月份前都要加0

function getNewDate() {
        //获取当前时间
        var date = new Date();
        var year = date.getFullYear();
        var month = date.getMonth() + 1;
        var day = date.getDate();
        if (month < 10) {
            month = "0" + month;
        }
        if (day < 10) {
            day = "0" + day;
        }
        var nowDate = year + month + day;
        console.log(nowDate );
       //答案 20180102

    }
