There is a wonderful script out there that populates email address, based on three elements passed to it: user, domain and suffix.

That script uses JavaScript to populate the mailto link, therefore making it inaccessible for spammers, which is something to take into consideration, especially if you’re a big corporate company. That is something I had to do for one of our sites.

Script itself is very easy:

<script language=”JavaScript”>
var user;
var domain;
var suffix;
function jemail(user, domain, suffix){
document.write(‘<a href=”‘ + ‘mailto:’ + user + ‘@’ + domain + ‘.’ + suffix + ‘”>’ + user + ‘@’ + domain + ‘.’ + suffix + ‘</a>’);
}
</script>

To populate the mailto link, you use it like that:

<script language=”JavaScript”>jemail(“test”, “mailserver”, “com”);</script>

However, all of the emails are stored as actual email adresses in our DB, looking like test@mailserver.com.

I couldn’t find anywhere online a tool to get those three elements of email address to use in that function, so I had to write it myself. Decided I’d share it with someone who might be looking for the same solution I was looking for.

Here is the code (assuming emailAddress is your DB field for email):

ColdFusion

<cfset user = RemoveChars(emailAddress, Find(“@”, emailAddress), Len(emailAddress))>
<cfset domain = RemoveChars(emailAddress, 1, Find(“@”, emailAddress))>
<cfset domain = RemoveChars(domain, Find(“.”, domain), Len(domain))>
<cfset suffix = RemoveChars(emailAddress, 1, Find(“.”, emailAddress))>

JavaScript

<script language=”JavaScript”>jemail(“#user#”, “#domain#”, “#suffix#”);</script>
