I have a facebook like button on my website, but the data-href attribute needs a link to like:<div class=fb-like share-button fbbutton data-href=htp://www.example.com/article/1.html data-send=false data-layout=button_count data-width=450 data-show-faces=true></div>I have a lot of pages, and would like to copy the code on all my pages, and the code would automatically detect the url it's in. Example: data-href=$link$ so that i don't need to change the link to that of my pages.Question: How do i make script, that detects its URL and displays it?note: Website is written in html5
