A twitter button question


i want to create a kind of button that can produce tweets with full sentences

for example

like that

but, what i really want, this link to mention the page urls (where the buttons is) in tweets
for example: http://i.imgur.com/Sf3lxpf.png
as you see, i want these kind of link which mention the url of the pages
but it must be in html format, because there are html area in my user profile page,in my little social networking site,
i want to put this button in their profile, in their profile there are photos and their personel things, music, video etc
using this button they can call their friends to show their things
the short version of my question
is there any code can detect the pages url and let integrate the url in the produced tweet ?
thank you
