js时间转化封装(支持所有格式)
作者:互联网
可随意组合自己需要的时间格式
//年:Y 月:m 日:d 时:h 分:i 秒:s 可随意组合(下面是调用函数例子,date是封装的函数) date('Y-m-d h:i:s',new Date().getTime())//2022-06-08 05:31:54 date('Y/m/d h:i:s',new Date().getTime())//2022/06/08 05:32:36 date('Y---m---d h-i-s',new Date().getTime())//2022---06---08 05-33-19
//时间格式转化 function date(format, times){//两个参数format是格式,times是时间戳 var a, jsdate=((times) ? new Date(times) : new Date());//获取时间戳 var pad = function(n, c){ if((n = n + "").length < c){ return new Array(++c - n.length).join("0") + n; } else { return n; } }; var txt_weekdays = ["Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday"]; var txt_ordin = {1:"st", 2:"nd", 3:"rd", 21:"st", 22:"nd", 23:"rd", 31:"st"}; var txt_months = ["", "January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"]; var f = {//获取天 // Day d: function(){return pad(f.j(), 2)}, D: function(){return f.l().substr(0,3)}, j: function(){return jsdate.getDate()}, l: function(){return txt_weekdays[f.w()]}, N: function(){return f.w() + 1}, S: function(){return txt_ordin[f.j()] ? txt_ordin[f.j()] : 'th'}, w: function(){return jsdate.getDay()}, z: function(){return (jsdate - new Date(jsdate.getFullYear() + "/1/1")) / 864e5 >> 0}, // Week W: function(){//获取周 var a = f.z(), b = 364 + f.L() - a; var nd2, nd = (new Date(jsdate.getFullYear() + "/1/1").getDay() || 7) - 1; if(b <= 2 && ((jsdate.getDay() || 7) - 1) <= 2 - b){ return 1; } else{ if(a <= 2 && nd >= 4 && a >= (6 - nd)){ nd2 = new Date(jsdate.getFullYear() - 1 + "/12/31"); return date("W", Math.round(nd2.getTime()/1000)); } else{ return (1 + (nd <= 3 ?
