date('D d F g:i A Y', $l2['available'])私は現在、この形式で日付を出力する次のようにPHPでフォーマットされた日付を持っています：Tue 15 May 5:45 PM 2012

Javascript/jQueryでこれと同じフォーマットを実現したいと思います。

これまで私はこれを行いました：

var lessonTime = new Date(data.lessons[i].available * 1000);
lessonTime.toDateString();

その結果、以下の日付になります。

Thu Mar 22 2012

PHPの日付関数でできるようにフォーマットを制御する方法はありますか？

私はmoment.jsを作成しましたが、日付の操作とフォーマットはかなり得意です。

moment().format('ddd D MMM h:mm A YYYY');

また、Date.jsよりも高速で小さく、Date.prototype一般的に安全でないと見なされているを変更しません。

JavaScriptにはネイティブの日付フォーマットはほとんどなく、PHPのフォーマット機能に匹敵するものはありません。これに役立つライブラリがいくつかあります。
