Date.prototype.toFormat = function (format?: string): string {

}
let day = `${this.getDate()}`;

seconds = `0${seconds}`;
}
return (format || "yyyy-MM-dd hh:mm:ss")
.replace(/yyyy/g, year)
.replace(/MM/g, month)
.replace(/dd/g, day)
.replace(/hh/g, hours)
.replace(/mm/g, minutes)
.replace(/ss/g, seconds);
}
使用方法
new Date().toFormat()
这种方式比较方便
