Simple Back Button
One of the most under-rated navigational tools is very simple to implement - if you know how!
You will doubtless have been to many Web sites that supply you with a means to hop back a page, to the one you've just come from - the "Back" button or link. It's a very useful adjunct to the normal buttons found on the menu and toolbars of most browsers, in that you can include the "Back" link anywhere you like on your page, so it's always handy.
It works by reading the user's History trail, and simply re-loading the last page visited. We've provided two versions:
Text link:
<a href="#" onClick="history.go(-1)">Back</a>
Button:
<input type=button value="Back" onClick="history.go(-1)">
You'll see that in both versions you have "history.go(-1)" which is a fairly obvious pointer to how it works. You can, of course, change the "(-1)" to "(-2)" or any other number that takes your fancy, although I can't think of a reason why you'd want to just at the moment!
Anyway, the example and code are here - enjoy!
