JS realization time format of the way to summarize _javascript skills

Copy Code code as follows:

Format method to extend date
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]: ("+ o[k]"). substr (("" + o[k]). length);
}
}
return format;
}
