将 JS 日期时间转换为 MySQL 日期时间

2021-11-20 00:00:00 javascript mysql

有谁知道如何将 JS 日期时间转换为 MySQL 日期时间?还有没有办法给 JS 日期时间添加特定的分钟数，然后将其传递给 MySQL 日期时间?

Does anyone know how to convert JS dateTime to MySQL datetime? Also is there a way to add a specific number of minutes to JS datetime and then pass it to MySQL datetime?

推荐答案

虽然 JS 确实拥有足够的基本工具来做到这一点，但它非常笨拙.

While JS does possess enough basic tools to do this, it's pretty clunky.

/**
 * You first need to create a formatting function to pad numbers to two digits…
 **/
function twoDigits(d) {
    if(0 <= d && d < 10) return "0" + d.toString();
    if(-10 < d && d < 0) return "-0" + (-1*d).toString();
    return d.toString();
}

/**
 * …and then create the method to output the date string as desired.
 * Some people hate using prototypes this way, but if you are going
 * to apply this to more than one Date object, having it as a prototype
 * makes sense.
 **/
Date.prototype.toMysqlFormat = function() {
    return this.getUTCFullYear() + "-" + twoDigits(1 + this.getUTCMonth()) + "-" + twoDigits(this.getUTCDate()) + " " + twoDigits(this.getUTCHours()) + ":" + twoDigits(this.getUTCMinutes()) + ":" + twoDigits(this.getUTCSeconds());
};
