with no link to sending an email; thus, the user had to open an email and
type in the email address by hand which is fraught with making typing errors.
To learn more, visit: http://innerpeace.org/escrambler.shtml I have modified their code further to make decoding even more impossible while simplifying their Java script.
The old way: I used to modify Email Addresses to prevent
"mining" of addresses from my websites by companies that send out "SPAM"
... ie: unsolicited advertisements to get rich quick, sell products and
promote adult websites. Thus, the email address: joedoe@mail.com
was represented by joedoeREMOVE@mail.com.
Another method was to make the email address a graphic:
with no link to sending an email; thus, the user had to open an email and
type in the email address by hand which is fraught with making typing errors.
The embedded link information would be: "mailto:joedoeREMOVE@mail.com
After clicking on the address, the browser will open a message window with the above address in the "To:" window. The sender needed to delete the letters "REMOVE" before clicking on "Send". This confused many people and resulted in emails which didn't reach the intended recipient.
There are three Java scripts for three forms of email addresses:
...... email link from the same email address.
..................... email link from text on page which is different from
the email address
.............. email link from an image, icon or animated GIF file
You can click on each of these to see the email page created.
EScrambler scrambles the email address by breaking it into two parts
"username" and the "domain" ...ie: "joedoe" and "mail.com".
I further break up the domain into two parts: "mail" and
"com". Also note: the word "mailto:" is scrambled increasing
the difficulty of the SPAM robot finding your email addresses.
I save the Java script in a text file using Microsoft Notepad for later use. I then open the text file, cut-and-paste the intended email address into the Java script. Next I copy the Java Script and paste it into the HTML code of the webpage.
When using Microsoft Word to create webpages, first select "View" and click on "Web Layout". The select "File" and click on "Save as Web Page". Now that the document is an official webpage, you can select "View" and click on "HTML Source". The trick is finding the correct place to "paste" the Java script into the HTML source code (search for closely associate text).
Using Netscape Composer, you select "Insert" and click on "HTML Tag
...". Then paste the Java script in the window displayed. This
leaves an icon representing the HTML
tag on your source webpage: 
but produces the appropriate script and image on the user's screen based
by executing the Java script contained within the HTML file. HTML
files are what the browser reads and interprets to produce the webpage
on your screen. When the browser encounters the Java script, the script
is executed which unscrambles and combines the various elements into an
email address ... but on your screen. Robots cannot find the address
in the scrambled Java script.
Be certain to replace "com" with "net", "us", etc. if necessary.
Normally it is best to use lower case except for AOL email addresses. Clicking
on each example in the second row should produce an Microsoft Outlook email
addressed to "joedoe@mail.com
