js converts long date format into standard date format

Copy code The code is as follows:

< script language="javascript">
//Extended Date format method
Date.prototype.format = function (format) {
var o = {
"M ": this.getMonth( ) 1,
"d ": this.getDate(),
"h ": this.getHours(),
"m ": this.getMinutes(),
"s ": this .getSeconds(),
"q ": Math.floor((this.getMonth() 3) / 3),
"S": this.getMilliseconds()
}
if (/ (y )/.test(format)) {
format = format.replace(RegExp.$1, (this.getFullYear() "").substr(4 - RegExp.$1.length));
}
for (var 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;
}
