1.函数封装date.js
Date.prototype.format = function(format) {
let o = {
"M+": this.getMonth() + 1,
"d+": this.getDate(),
"H+": this.getHours(),
"m+": this.getMinutes(),
"s+": this.getSeconds(),
"q+": Math.floor((this.getMonth() + 3) / 3),//季度
"f+": this.getMilliseconds(),//毫秒
};
if(/(y+)/.test(format))
format = format.replace(RegExp.$1, this.getFullYear() + "").substr(4 - RegExp.$1.length);
for(let k in o) {
if(new RegExp("(" + k + ")").test(format))
format = format.replace(RegExp.$1, (RegExp.$1.length == 1) ? (o[k]) : (("00" + o[k]).substr(("" + o[k]).length)));
}
return format;
}
2.nodejs中可以通过require直接使用
require('./date.js');
var date = new Date();
console.log(date.format('yyyy/MM/dd HH:mm:ss'));
3.结果
