One of the Figleaf guys posted a much nicer version of this using regex a
month or so back, so you may want to check the archives.
Here is what I use to keep people from typing characters in text fields
though.
This goes in head
<SCRIPT TYPE="text/javascript">
<!--
function letternumber(e)
{
var key;
var keychar;
if (window.event)
key = window.event.keyCode;
else if (e)
key = e.which;
else
return true;
keychar = String.fromCharCode(key);
keychar = keychar.toLowerCase();
// control keys
if ((key==null) || (key==0) || (key==8) ||
(key==9) || (key==13) || (key==27) )
return true;
// alphas and numbers
else if ((("abcdefghijklmnopqrstuvwxyz0123456789 ").indexOf(keychar) > -1))
return true;
else
return false;
}
//-->
</SCRIPT>
Call it with this in you input tag.
onKeyPress="return letternumber(event)"
Just change the characters to whatever you want. It will work for spaces
also.
Of course though, you should never rely on javascript...
