history.go('url') issue

Question

I've seen that history.go() method can have two types of parameter:

see:

 http://www.w3schools.com/jsref/met_his_go.asp 

But url does not working at all.

I use JavaScript console of browser to test this method but got no success.

I know that there are security issues, that you can't read history entries. You can just go back and forward.

So why this string parameter listed in all js references?

Answer 1

Supplying a URL as a parameter is a non-standard feature and will not work in all browsers. Most browsers accept only a relative number, eg 1 or -1 .

From the MDC documentation (emphasis mine):

[ history.go(integerDelta) ] Loads a page from the session history, identified by its relative location to the current page, for example -1 for the previous page or 1 for the next page. When integerDelta is out of bounds (eg -1 when there are no previously visited pages in the session history), the method doesn't do anything and doesn't raise an exception. . 。

This is what happens when you use W3Schools as a learning resource;-)

Answer 2

MDC at least has this note:

Note: Internet Explorer supports passing string URLs as a parameter to go(); this is non-standard and not supported by Gecko.

No idea why it is listed in many references, though.

Answer 3

If you want to use it with an URL just use:

window.location.href="http://www.whereyouwannago.nl/";

The URL is problably still there for backwards compatibility
