JS——获取当前日期格式及日期比较

//获取当前时间，格式YYYY-MM-DD
            function getNowFormatDate() {
                var date = new Date();
                var seperator1 = "/";
                var year = date.getFullYear();
                var month = date.getMonth() + 1;
                var strDate = date.getDate();
                if (month >= 1 && month <= 9) {
                    month = "0" + month;
                }
                if (strDate >= 0 && strDate <= 9) {
                    strDate = "0" + strDate;
                }
                var currentdate = year + seperator1 + month + seperator1 + strDate;
                return currentdate;
            }

            //比较日期大小
            function compareDate(date1, date2) {
                var date1 = new Date(date1);
                var date2 = new Date(date2);
                if (date1.getTime() > date2.getTime()) {
                    return true;
                } else {
                    return false;
                }
            }
