A javascript snippet like this works wonders (this one even has
multiple modes where it'll print either like "Your Name Here" or "Your
Name Here [EMAIL-REMOVED]>" or just [EMAIL-REMOVED]" as mailto: links
in the document)
<script type="text/javascript"><!--
// lhs = left hand side, rhs = right hand side
function printMailToLink(name, lhs, rhs, type)
{
document.write("<" + "A HREF=\"mailto" + ":" + lhs + "@" +
rhs + "\">");
if (type == "full") {
document.write(name + " - <" + lhs + "@" + rhs + ">");
}
if (type == "name") {
document.write(name);
}
if (type == "address") {
document.write(lhs + "@" + rhs);
}
document.write("<" + "/a" + ">");
}
//-->
</script>
Then, to use it in your page:
<script type="text/javascript">
printMailToLink("Eric Ladner", "eric.ladner", "gmail.com", "address")
</script>
That'll kill 99.9% of page scraping since basially they are looking
for \w+@\w+.\w+ (I'm oversimplifying the regular expression, of
course).
There's not much I know of that you can do along the lines of CSS with
this. The goal is to keep things out of the page that look like an
email address and CSS doesn't have the ability to change or generate
content. Although there is a way to generate content with CSS2 as per
the spec, IE doesn't implement it, so you're still forced to work
around it with something else.
Cheers.
