This is a simple script that many programmers know. Most of the users feel that this is a waste since the browsers Forward-Back buttons are already present. But you would realize that in case you are creating a window without the standard toolbars as shown in Example No.3 , then you would find this script to be very useful to emulate the Browsers buttons.
I have shown 2 ways.. I prefer the image one, since it looks really neat in case you have nice image.
<BODY>
<FORM>
<INPUT TYPE="image" SRC="N.jpg" NAME="back" onClick="window.history.go(-1)">
<INPUT TYPE="button" VALUE="Go Back" NAME="back" onClick="window.history.go(-1)">
<INPUT TYPE = "button" VALUE = "GO Forward" onClick = "window.history.go(1);">
</FORM>
</BODY>
