私は jQuery 開発者ではありませんが、次のような出力が必要です。
2007 年 6 月 9 日土曜日、午後 5 時 46 分 21 秒
このコード ( jsFiddle ) を確認してください。
<span id="date"></span>
var now = new Date();
dateFormat(now, "dddd, mmmm dS, yyyy, h:MM:ss TT");
// Saturday, June 9th, 2007, 5:46:21 PM
$('#date').append(now);
ありがとう。
var now = moment().format("dddd, MMMM Do, YYYY, h:mm:ss A");
// Saturday, June 9th, 2007, 5:46:21 PM
$('#date').append(now);
出力：

ただし、 Ian Atkin が見つけた古い (2009) date.format.jsを使用し、最初に含める必要がある場合は、何も変更する必要はありません。

このリンクで利用可能なこのdateFormat関数を使用します。あなたが尋ねたのとまったく同じ形式です。
関数を含めると、コードを変更せずに実行できます。

これにより、PHP のdate関数と同じように日付をフォーマットできます。
更新機能が改善され、正確で望ましい出力が得られます。
理由はわかりませんが、空の文字を追加すると、目的の出力が得られます
また、私appendはhtml
now2PS :出力を表示するために変数の前後に空白文字を追加する必要がある理由を、より経験豊富な人から知りたいです。
var now = moment().format("dddd, MMMM Do, YYYY, h:MM:ss A");
// ___day, month _th, 20__, _:__:__ _M
$('#date').append(now);
フォーマット: 2007 年 6 月 9 日土曜日、午後 5 時 46 分 21 秒。このコードは機能します。
