How to get previous URL in IE?

window.history.current
window.history.previous
window.history.next

Are all suported from NS3 and IE4 onwards.

You can use...

prevURL = window.history.previous;

document.write( "The previous history string is: " + prevURL);

Huh - jmulder, how do you get that info???

Only NETSCAPE and ONLY with a signed script using UniversalBrowserRead access may look at the history.

You can look at document.referrer if is is set, but that is only the case if the previous page was a web page too - so not bookmarks or url typed in or dropped

Michel

netscape.security.PrivilegeManager.enablePrivilege("UniversalBrowserRead");
document.write(history.toString())
netscape.security.PrivilegeManager.disablePrivilege("UniversalBrowserRead");


Michel

These are not supported in IE, and even in Netscape need signed scripts.

Sorry to repeat what you said Michel, your comment was not there when I posted :-)

LOL

Michel

Oops!

I forgot to add the line:

netscape.security.PrivilegeManager.enablePrivilege("UniversalBrowserRead");

at the top of the example.

I got it from my Sams manual: Pure JavaScript by Wyke, Gilliam and Ting. pg 748.

Funny...this book is usually quite accurate :(

Didn't mean to cause an avalanche of disgust.

LOL - does it say it is supported by IE4 - and then has
netscape.security.PrivilegeManager ???
Hmmm

Michel

>> does it say it is supported by IE4

Yep. JavaScript1.1+, ECMASCript1.0+, JScript3.0+, Nav3+, IE4+

And in the appendix in the list for IE-supported syntax is: history.next, history.previous, history.current

The example given has a note which reads:
"In Navigator 4 and later, getting the next value requires the UniversalBrowserRead privilege."

Actually you can get previous page under document.referrer

As I already said:
"You can look at document.referrer if is is set, but that is only the case if the previous page was a web page too - so not bookmarks or url typed in or dropped"

Huh?

imulder, I am the one who ask this question.  I actually use exactly the same reference book to you.  But when u used these properties become "undefined" in IE.  Then I found in a web stating that those properties work only in Netscape.
Now the question become: if I use document.referrer, I still cannot get the previous URL, what should I do?

Can I do it by VBScript or JScript instead?  I accept these two languages even though they may not work in Netscape.

A very interesting article about "Speeding Up Frame Rates For DHTML Animation in Win98" :-?

As you can see from my posts...I have no experiance using this call...I just looked it up for you...the others seem to have more info.

>> I actually use exactly the same reference book to you.

It's usually a very good book.

Try this one!
<script language=javascript>
   alert("The previous page URL is "+document.referrer);
</script>

Come on  cstsang  - you have been a member long enough not to answer a question that has many comments - TWO of which are using what you suggest!!!

Kennon: Please reject cstsang's answer

Thanks

Michel

I only ever post comments since I believe there is always the possibility (and sometimes probability) that someone can give a better solution.

So, is it possible to remove an answer (or change it to a comment) if it where accidently posted as such?

Of course I will reject cstsang's answer as it is actually not proposed by him.
But...could anyone can give me any possible suggestion to solve this problem? It is very different between getting a previous document and getting the previous URL.

Kennon2000

If the document.referrer works for you, that is the one to use.

Michel

Although it is not exactly what I want, Michel gave me a possible approval.

Sorry I could not be of more service...

If you are desparate and the user allows you, you might use wsh to read the MRU list (most recently used) off the registry, but I guess you are not THAT desparate ;-)
