Spamsikring af emailadresser

JS ville nok have hjulpet dig lidt bedre, du kunne evt bruge den måde at Smarty gør det på:

Ja ok - jeg må erkende, at jeg ikke lige kan gennemskue den kode 100 pct.
Men på din opfordring vil jeg poste denne i js i stedet i håb om at finde noget, der er lettere at gå til. Du skal dog have point for indsatsen, post et svar:)

Nu er det ikke en så svær kode:
$address = "to@email.com"; // modtager
$extra = ""; // bcc subj osv...
$text = "til navn"; // Link navn

$string = '<a href="mailto:'.$address.'" '.$extra.'>'.$text.'</a>';
for($x = 0, $y = strlen($string); $x < $y; $x++ ) {
    $ord[] = ord($string[$x]);
}

$_ret = "<script type=\"text/javascript\" language=\"javascript\">\n";
$_ret .= "<!--\n";
$_ret .= "{document.write(String.fromCharCode(";
$_ret .= implode(',',$ord);
$_ret .= "))";
$_ret .= "}\n";
$_ret .= "//-->\n";
$_ret .= "</script>\n";

echo $_ret;
f.eks det var så javascript_charcode delen, de andre er lige så (hvis du hellere vil bruge en af dem)

Men hvordan skal jeg få den til at virke, når jeg indtaster emailadresserne som del af et længere tekststykke og ikke som seperat felt i mit admin.
Har du set den side, det drejer sig om?

Så er der ikke andet for du må igang manuelt:
<script type="text/javascript" language="javascript">
<!--
{document.write(String.fromCharCode(60,97,32,104,114,101,102,61,34,109,97,105,108,116,111,58,102,111,114,109,97,110,100,64,109,101,108,111,100,105,103,114,97,110,100,112,114,105,120,102,97,110,107,108,117,98,46,100,107,34,32,62,102,111,114,109,97,110,100,64,109,101,108,111,100,105,103,114,97,110,100,112,114,105,120,102,97,110,107,108,117,98,46,100,107,60,47,97,62))}
//-->
</script>

Jeg takker - så må jeg i gang pr håndkraft:)
Smid et svar, og du vil modtage dine points;)

Ellers tak...

Så tager jeg dem selv.
Tak for hjælpen:)
