将javascript转换为日期对象为mysql日期格式(YYYY-MM-DD)

可能最好使用像这样的图书馆 Date.js (尽管这已经有好几年没有维持了)或者 Moment.js

但要手动执行,可以使用 Date#getFullYear() Date#getMonth() (它以0=一月开始,所以您可能想要+1),并且 Date#getDate() (月日)。只需将月份和日期填充为两个字符,例如:

(function() {
    Date.prototype.toYMD = Date_toYMD;
    function Date_toYMD() {
        var year, month, day;
        year = String(this.getFullYear());
        month = String(this.getMonth() + 1);
        if (month.length == 1) {
            month = "0" + month;
        }
        day = String(this.getDate());
        if (day.length == 1) {
            day = "0" + day;
        }
        return year + "-" + month + "-" + day;
    }
})();

用法:

var dt = new Date();
var str = dt.toYMD();

使用当地时间;对于UTC,只需使用UTC版本( getUTCFullYear

警告:我刚刚把它扔掉了,它完全没有经过测试。

去约会

new Date().toJSON().slice(0, 10)
//2015-07-23

日期时间

new Date().toJSON().slice(0, 19).replace('T', ' ')
//2015-07-23 11:26:00

var myDate = new Date();
var myDate_string = myDate.toISOString();
var myDate_string = myDate_string.replace("T"," ");
var myDate_string = myDate_string.substring(0, myDate_string.length - 5);

最短版本的 https://stackoverflow.com/a/11453710/3777994 :

/**
 * MySQL date
 * @param {Date} [date] Optional date object
 * @returns {string}
 */
function mysqlDate(date){
    date = date || new Date();
    return date.toISOString().split('T')[0];
}

使用:

var date = mysqlDate(); //'2014-12-05'

function js2Sql(cDate) {
    return cDate.getFullYear()
           + '-'
           + ("0" + (cDate.getMonth()+1)).slice(-2)
           + '-'
           + ("0" + cDate.getDate()).slice(-2);
}

date.toISOString().split("T")[0]

在第一个例子中有点输入错误,当一天的长度小于1时,它会将月份而不是日期添加到结果中。

如果你改变了,效果会很好:

    if (day.length == 1) {
        day = "0" + month;
    }

到

    if (day.length == 1) {
        day = "0" + day;
    }

修正后的函数如下所示:

Date.prototype.toYMD = Date_toYMD;
function Date_toYMD() {
    var year, month, day;
    year = String(this.getFullYear());
    month = String(this.getMonth() + 1);
    if (month.length == 1) {
        month = "0" + month;
    }
    day = String(this.getDate());
    if (day.length == 1) {
        day = "0" + day;
    }
    return year + "-" + month + "-" + day;
}

Object.defineProperties( Date.prototype ,{
    date:{
         get:function(){return this.toISOString().split('T')[0];}
    },
    time:{
         get:function(){return this.toTimeString().match(/\d{2}:\d{2}:\d{2}/)[0];}
    },
    datetime:{
         get : function(){return this.date+" "+this.time}
    }
});

现在你可以用

sql_query = "...." + (new Date).datetime + "....";

我需要这个文件名和当前时区的时间。

const timezoneOffset = (new Date()).getTimezoneOffset() * 60000;

const date = (new Date(Date.now() - timezoneOffset))
    .toISOString()
    .substring(0, 19)
    .replace('T', '')       // replace T with a space
    .replace(/ /g, "_")     // replace spaces with an underscore
    .replace(/\:/g, ".");   // replace colons with a dot

查看这个方便的库,以满足您的所有日期格式设置需求: http://blog.stevenlevithan.com/archives/date-time-format

// function
getDate = function(dateObj){
    var day = dateObj.getDay() < 9 ? '0'+dateObj.getDay():dateObj.getDay();
    var month = dateObj.getMonth() < 9 ? '0'+dateObj.getMonth():dateObj.getMonth();
    return dateObj.getFullYear()+'-'+month+'-'+day;
}

// example usage
console.log(getDate(new Date()));

// with custom date
console.log(getDate(new Date(2012,dateObj.getMonth()-30,dateObj.getDay()));

可以是!

function Date_toYMD(d)
{
    var year, month, day;
    year = String(d.getFullYear());
    month = String(d.getMonth() + 1);
    if (month.length == 1) {
        month = "0" + month;
    }
    day = String(d.getDate());
    if (day.length == 1) {
        day = "0" + day;
    }
    return year + "-" + month + "-" + day;
}

dateTimeToMYSQL(datx) {
    var d = new Date(datx),
      month = '' + (d.getMonth() + 1),
      day = d.getDate().toString(),
      year = d.getFullYear(),
      hours = d.getHours().toString(),
      minutes = d.getMinutes().toString(),
      secs = d.getSeconds().toString();
    if (month.length < 2) month = '0' + month;
    if (day.length < 2) day = '0' + day;
    if (hours.length < 2) hours = '0' + hours;
    if (minutes.length < 2) minutes = '0' + minutes;
    if (secs.length < 2) secs = '0' + secs;
    return [year, month, day].join('-') + ' ' + [hours, minutes, secs].join(':');
  }

请注意,您可以删除小时、分钟和秒,结果为YYYY-MM-DD 优点是在HTML表单中输入的datetime保持不变:不转换为UTC

结果将是(例如):

dateToMYSQL(datx) {
    var d = new Date(datx),
      month = '' + (d.getMonth() + 1),
      day = d.getDate().toString(),
      year = d.getFullYear();
    if (month.length < 2) month = '0' + month;
    if (day.length < 2) day = '0' + day;
    return [year, month, day].join('-');
  }

new Date().toISOString().replace('T', ' ').split('Z')[0];
