In fact, "not Valid" is a bit exaggerated. It is not (and AIUI cannot be
made) Valid HTML. It can be made Valid XHTML by declaring the attribute, as
mentioned above:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/dtd/xhtml1-strict.dtd"
[
<!ATTLIST input
autocomplete (off|on) "on"
>
]>
But the problem is that XHTML itself is not interoperable yet, and when
parsed by a tagsoup parser (which is highly likely if served as
IE-compatible text/html), part of the declaration is displayed (even with
Geckos, which is most unfortunate as they do have an XML parser.)
Therefore, trying to address this proprietary feature with an equally
proprietary property of the corresponding DOM element object appears to be
one of the better solutions. Especially since client-side scripting is
involved here anyway. For example:
....
<head>
...
<meta http-equiv="Content-Script-Type" content="text/javascript"></meta>
<script type="text/javascript">
// <![CDATA[
/**
* @depends http://pointedears.de/scripts/types.js
*/
function disableAutoComplete(f)
{
if (f)
{
for (var es = f.elements, i = es && es.length; i--;)
{
var e = es[i];
if (e.tagName.toLowerCase() == "input"
&& e.type.toLowerCase() == "text")
{
if (typeof e.autoComplete == "string")
{
e.autoComplete = "off";
}
else if (isMethodType(typeof e.setAttribute)
&& e.setAttribute)
{
e.setAttribute("autocomplete", "off");
}
}
}
}
}
// ]]>
</script>
</head>
<body onload="disableAutoComplete(document.forms[0])">
<form ...>
...
</form>
...
</body>
