 Its an unfortunate thing, but the internet certainly has its share of
 unscrupulous people.  In my opinion, the worst amongst these are those
 that deploy software robots to roam the web and harvest email addresses
 from web pages.  These addresses are then collated into huge databases and
 sold for the purpose of spam.

 Now we all hate spam and anything that can be done to reduce it is very
 worthwhile.  This is not rocket science and a basic knowledge of html and
 how to cut and paste will see you protected from the spambots.  All we are
 going to use is a bit of javascript.

 First, open Notepad or any text editor and then copy and paste the
 following into the file.

 /* This script provides for a straightforward email address in a web page.

 In your web page add the following:-

 blocker("insert first part of email address") */

 function blocker(name)



 var domain ="yourdomainname.com";

 document.write('' + name + '@' + domain + '');



 /* This script adds a subject field to the email.

 function blockersubject(name,subject)



 var domain ="yourdomainname.com";

 document.write('' + name + '@' + domain + '');



 /*  This script is for using as an "Email Us" or like in a menu system or
 on a page.

 Insert the following in your web page:-

 blocker2('First Part of Email','The text you want to appear on the web
 page');

 function blocker2(name,text)



 var domain ="yourdomainname.com";

 document.write('' + text + '');



 /*  This script allows the adding of a subject, but also displayable text
 for a menu system.  In your web page place the following:-

 blockersubject2('first part of email address','The Subject in the
 email','The text to appear in the email');*/

 function blockersubject2(name,subject,text)



 var domain ="yourdomainname.com";

 document.write('' + text + '');



 //End of file.

 Save the file as blocker.js in your document folders because this script
 can be reused over and over for as many different web pages as you like.
 You only need to change the variables in the script.

 To get the scripts to work, there are a couple of things you need to do.
 I usually create a sub-directory for my javascript and actually call it
 that.  Any javascript for the web page can be stored there.  Save a copy
 of the file blocker.js to this directory and then edit all the variables
 to suit your site.

 Now you need to allow the scripts to be called and the web page needs to
 know where they are.  The easiest way to achieve this is to have the
 information in the  section of your document.  Before the closing  tag,
 and assuming you have saved the file to a javascript sub-directory, insert
 the following line of code:-

 (Insert less than sign)script type="text/javascript"
 src="javascript/common.js (insert less than sign)/script>

 You will just have to make sure that the path to the javascript sub-
 directory is correct for the document.  This is simple if you use
 Dreamweaver as you can modify the template for your site and it will
 update all the pages.  If you are using php includes, you will need to
 make sure that the path is correct from your header template through to
 the javascript directory.  A little playing will usually get this sorted
 out for you.

 One final thing that you should be aware of and that is that not everyone
 has javascript turned on.  If a visitor hits your page and has javascript
 turned off then they wont be able to see your email addresses at all.  To
 resolve this, enter the following code just below the area where the email
 address is supposed to appear.

 (Insert less than sign)noscript>If you are seeing this, then Javascipt is
 not turned on in your browser and you wont be able to see our email
 addresses.  They are hidden by Javascript.   You can either turn your
 Javascript on or alternately email us at youraddress at domainname dot
 com(insert less than sign)/noscript>

 Make sure you do not use the @ sign or put the dot in or even type the
 full email address properly.  You will destroy all the good work youve
 done.

 And there you have it.  A simple piece of javascript that will prevent
 your email address being harvested by the nasty little bots that roam the
 web.
