FORWARD & BACK BUTTONS
<form>
<input type="button" value="<< Back" onClick="history.back(-1)" />
</form>
<form>
<input type="button" value="Forward >>" onClick="history.go(1)" />
</form>
FORWARD & BACK LINKS
<a href="javascript:history.back(-1)"><< Back</a>
<< Back
Alternatively, if you wanted to go forward instead of backward in the history, you would write the code thus:
<a href="javascript:history.go(1)"> Go Forward >> </a>
Forward >>
The numbers in the parentheses are the number of pages to move (forward or back, respectively, in the above examples). You can also move more than one page; for instance javascript.history.go(-3) would navigate three pages back in the history. Note that if there is no page in the history to go to, the JavaScript does not error out; it simply does nothing.
