Is site first item in history?
How to find out if site is the first item in history? This doesn't work because of security reasons:
if(window.history.item(0)==window.locatio开发者_C百科n.href)
For security reasons the History object doesn't allow the non-privileged code to access the URLs of other pages in the session history, but it does allow it to navigate the session history.
From: Mozilla Developer Center: window.history
