Date.prototype.format_javascript techniques for TIME format processing functions under JavaScript

Example one:

A full JS time processing function, although I did not carefully to study inside the regular, but I passed the test, is very good, you can according to your own needs to set the time format of the string output, I applied to the format: mm/dd/yyyy hh:mm tt and YYYY-MM-DD HH:mm:ss.

<span style= "FONT-SIZE:18PX;" 
>date.prototype.format = function (mask) {var d = this; 
var zeroize = function (value, length) {if (!length) length = 2; 
Value = String (value); 
for (var i = 0, zeros = '; i < (length-value.length); i++) {zeros = = ' 0 '; 
return zeros + value; 
}; return Mask.replace (/"[^"]* "|") [^ ']* ' |\b (?:d {1,4}|m{1,4}|yy (?: yy)? | ([HHMSTT]) \1?| [Llz]) 
\b/g, function ($) {switch ($) {case ' d ': return D.getdate (); 
Case ' DD ': Return Zeroize (D.getdate ()); 
Case ' DDD ': return [' Sun ', ' Mon ', ' Tue ', ' Wed ', ' Thr ', ' Fri ', ' Sat '][d.getday ()]; 
Case ' dddd ': return [' Sunday ', ' Monday ', ' Tuesday ', ' Wednesday ', ' Thursday ', ' Friday ', ' Saturday '][d.getday ()]; 
Case ' M ': Return D.getmonth () + 1; 
Case ' MM ': Return Zeroize (D.getmonth () + 1); 
Case ' MMM ': return [' Out of the window ', ' Feb ', ' Mar ', ' Apr ', ' may ', ' June ', ' o ', ' Aug ', ' Sep ', ' Oct ', ' Nov ', ' Dec '][d.getmonth ()]; Case ' MMMM ': return [' January ', ' February ', ' March ', ' April ', ' may ', ' June ', ' July ', ' August ', ' Septe 'Mber ', ' October ', ' November ', ' December '][d.getmonth ()]; 
Case ' yy ': Return String (D.getfullyear ()). substr (2); 
Case ' yyyy ': return D.getfullyear (); Case ' H ': return d.gethours ()% 12 | | 
12; 
Case ' hh ': Return Zeroize (d.gethours ()% 12 | | 12); 
Case ' H ': return d.gethours (); 
Case ' HH ': Return Zeroize (D.gethours ()); 
Case ' m ': return D.getminutes (); 
Case ' mm ': Return Zeroize (D.getminutes ()); 
Case ' s ': return D.getseconds (); 
Case ' SS ': Return Zeroize (D.getseconds ()); 
Case ' l ': Return Zeroize (D.getmilliseconds (), 3); 
Case ' L ': var m = d.getmilliseconds (); 
if (M >) m = Math.Round (M/10); 
Return Zeroize (m); Case ' TT ': Return d.gethours () < 12? 
' Am ': ' PM '; Case ' TT ': Return d.gethours () < 12? 
' AM ': ' PM '; 
Case ' Z ': Return d.toutcstring (). Match (/[a-z]+$/); 
Return quoted strings with the surrounding quotes removed Default:return $0.substr (1, $0.length-2); 
} 
});  };</span>

Example two:

The Date.prototype.format method extends the format method in the prototype of date so that it can easily format the date format output.

Date.prototype.format =function (format)
{
var o = {
"m+": This.getmonth () +1,//month
"d+": This.getdate (),//day
"h+": this.gethours (),//hour "m+"
: This.getminutes (),//minute
"s+": This.getseconds (),//second
"q+": Math.floor ((This.getmonth () +3)/3),//quarter
"S": this.getmilliseconds ()//millisecond
}
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;
}
var date = new Date (parseint ("1347497754133"));
Date.format ("Yyyy-mm-dd");

The above through two pieces of instance code to introduce the JavaScript time format processing function Date.prototype.format related content, I hope to help.
