slash in 'anchor'

[eluser]johnmiller[/eluser]
Hi all...

I have a doubt in putting slashes in 'anchor'

suppose below given is my code

Code:

anchor ('example.com/class/function/ID/', click me);

but when i view this in address bar, i won't get slash at the end (means, after ID)

in the address bar, i want it like http://example.com/class/function/ID/

but i get http://example.com/class/function/ID (without slash in the end)

how to add slash at the end???
