Reg Expression validation

[florida]

Please verify if I have this correct:



if(!/a-zA-Z0-9\//.test(document.pagename.fieldname.value))
{
alert("Invalid entry. Only letter, numbers and / are allowed.");
}



I want to send a message if something entered is not a letter(a through z capital and lowercasae) or a number or a "/").

Does it not SEEM to be working? Try this instead.

(document.pagename.fieldname.value).match(/[a-zA-z0-9\/]+/)

Note, however, that all that will do is ensure that there is at least one valid character, not that all characters are valid.

Try this instead.if (/[^a-z\/]/i.test(document.pagename.fieldname.value))
alert("Invalid entry. Only letter, numbers and / are allowed.");

Try this instead.Just forgot about the numbers, which bring us to:
if (/[^a-z0-9\/]/i.test(document.pagename.fieldname.value)) {
alert("Invalid entry. Only letter, numbers and / are allowed.");
}
