获取当前时间方法

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

其他：

// 获取当前日期加减天数
function getDateStr(addDay) {
    var date = new Date();
    date.setDate(date.getDate() + addDay);
    var year = date.getFullYear();
    var month = date.getMonth() + 1;
    var day = date.getDate();
    return year + "-" + month + "-" + day;
}

// 时间转字符串，转成yyyy-MM-dd HH:mm:SS格式
function dateToStr(datetime) {
    var dateTime = new Date(datetime);
    var year = dateTime.getFullYear();
    var month = dateTime.getMonth() + 1;
    var date = dateTime.getDate();
    var hour = dateTime.getHours();
    var minutes = dateTime.getMinutes();
    var second = dateTime.getSeconds();

    if (month < 10) {
        month = "0" + month;
    }
    if (date < 10) {
        date = "0" + date;
    }
    if (hour < 10) {
        hour = "0" + hour;
    }
    if (minutes < 10) {
        minutes = "0" + minutes;
    }
    if (second < 10) {
        second = "0" + second;
    }

    return year + "-" + month + "-" + date + " " + hour + ":" + minutes + ":" + second;
}
