....?subject= ....

Notice that there should not be any spaces between the parameter name and the equal sign. To send the current page's URL in a mail message, we just assemble the current location.href in the body part:

&body= ...location.href...

To make the message even more attractive, we decorate both its subject and its body with the current page's title, document.title. The following mailpage() function assembles the mail message and posts it to the browser's Address field:

<script language="javascript">
function mailpage()
{
  mail_str = "mailto:?subject= Doc JavaScript: " + document.title;
  mail_str += "&body= I recommend Doc JavaScript's (docjavascript.com) tip -- " + document.title;
  mail_str += ". You should check this out at, " + location.href; 
  location.href = mail_str;
}
</script>

Somewhere on the page you need to provide a link that calls the above function, like this:

<A HREF = "javascript:mailpage()">E-mail This Page</A> E-mail This Page
