Javascript formatted Date and Time method summary, javascript date

Example 1:

<! DOCTYPE html> 
Example 2:

<Script type = "text/javascript"> var date = new Date (); document. writeln (date); // Thu Jan 08 2015 01:25:53 GMT + 0800 (China Standard Time) document. writeln (Date. parse (); // NaN document. writeln (Date. parse ('2014/1/123'); // 6/10 ms document. writeln (Date. parse ('thu Jan 08 2015 01:25:53 '); // 1420651553000 Ms document. writeln (Date. UTC (); // NaN // Date formatting method document. writeln ('<br/>'); document. writeln (date. toDateString (); // Thu Jan 08 2015 document. writeln ('<br/>') document. writeln (date. toTimeString (); // 01:39:08 GMT + 0800 (China Standard Time) document. writeln ('<br/>') document. writeln (date. toLocaleDateString (); // October January 8, 2015 document. writeln ('<br/>') document. writeln (date. toLocaleTimeString (); // 1:39:08 document. writeln ('<br/>') document. writeln (date. toUTCString (); // Wed, 07 Jan 2015 17:39:08 GMT // some set and get methods </script>
Example 3:

Date. prototype. format = function (formatStr) {var str = formatStr; var Week = ['day', 'yi', '2', '3', '4', '5 ', '6']; str = str. replace (/yyyy | YYYY/, this. getFullYear (); str = str. replace (/yy | YY/, (this. getYear () % 100)> 9? (This. getYear () % 100 ). toString (): '0' + (this. getYear () % 100); str = str. replace (/MM/, (this. getMonth () + 1)> 9? (This. getMonth () + 1 ). toString (): '0' + (this. getMonth () + 1); str = str. replace (/M/g, (this. getMonth () + 1); str = str. replace (/w | W/g, Week [this. getDay ()]); str = str. replace (/dd | DD/, this. getDate ()> 9?

This. getSeconds (). toString (): '0' + this. getSeconds (); str = str. replace (/s | S/g, this. getSeconds (); return str}
Example 4:

Date. prototype. toString = function (format, loc) {var time = {}; time. year = this. getFullYear (); time. TYear = ("" + time. year ). substr (2); time. month = this. getMonth () + 1; time.
