Its a bit difficult to explain, but i will try.
Whenever someone clicks on a anchor link, temporarly a dotted box appears around it. For example, when u click on the stackoverflow logo over the top of this page, it is surrounded by a dotted line temporarily. Because the page gets refreshed, the dotted box goes away.
But with ajax, the link doesnt get refresh, hence the dotted box remains on it. How to remove that dotted box. When you click somewhere on the page the dotted box goes away. How to do it using jquery or any other way.
