Opera9.24でJavaScript動かしてみた。
これまた、面白いというか…おかしなというか…
何を信じたらいいのｗ
これ見たらIEがシンプルな挙動しょうるな。
IEはHTMLの規定の属性名がデフォで小文字であって、FirefoxやOperaは解析しながら属性を追加していきょんかな？基本はMapっぽい？
そのときFirefoxは属性名を小文字にしますよと。
OperaはHTMLの規定の属性名は大文字で、その他の属性名はHTMLの記述通りよと。でもARGはなくなっとるな…
ま、こんな使い方せんからええんじゃろうけど。

<html>
  <head>
    <script type="text/javascript">
      function hoge() {
      
        var objIdForm = document.getElementById('form');
        var objNameForm = document.getElementsByName('form');

        var msgNamedNodeMap = "\n" + objIdForm.attributes.length;
        for ( var i = 0 ; i < objIdForm.attributes.length ; i++ ) {
            msgNamedNodeMap = msgNamedNodeMap + "\n<" + i +">" + objIdForm.attributes.item(i).name + " = " + objIdForm.attributes.item(i).value;
        }
        
        document.getElementById('msg').value = msgNamedNodeMap;
        
      }
    </script>
  </head>
  <body>
    <form id="form" value="ふぉーむ" numeric="123" multibyte="一二三" UPPERCASE=123 arg="引数" ARG="匹数">
      <textarea id="msg" name="msg" rows=20 cols=50>
      </textarea>
      <input type="button" onclick="hoge()" value="ほげ">
    </form>
  </body>
</html>

【Firefox 2.0.0.8】
6<0>arg = 引数 ←匹数はおらんようになっとる
<1>uppercase = 123 ←名前が小文字になっとる

【Opera 9.24】
9<0>ID = form<1>VALUE = 0 ←なんで０なん？なんで大文字なん？
