检测是否直接访问了网站。是否可以？

Question

It is possible to detect if my website was visited directly (by user typing in the address as the URL) or if they have visited it by a link they found elsewhere or by a google search result link? Is this even possible?

Answer 1

You can use:

document.referrer

which returns 'A String, representing the URL of the document that loaded the current document. Returns the entire URL, including the protocol (like http://). If the current document was not opened through a link (for example, through a bookmark), an empty string is returned.'
