Abrir página

[DIRAB51]

Hola. tengo este codigo para abrir una pagina en otra ventana, pero me gustaria añadir en la ventana los botones para ir pagina adelante o pagina atras, podrial alguien decirme lo que debo de poner.

<SCRIPT language=JavaScript>
<!-- Begin


function expandingWindow(website) {
var windowprops='width=100,height=100,scrollbars=yes,s tatus=yes,resizable=yes'
var heightspeed = 5; // vertical scrolling speed (higher = slower)
var widthspeed = 9; // horizontal scrolling speed (higher = slower)
var leftdist = 0; // distance to left edge of window
var topdist = 0; // distance to top edge of window

if (window.resizeTo&&navigator.userAgent.indexOf("Ope ra")==-1) {
var winwidth = window.screen.availWidth - leftdist;
var winheight = window.screen.availHeight - topdist;
var sizer = window.open("","","left=" + leftdist + ",top=" + topdist +","+ windowprops);
for (sizeheight = 1; sizeheight < winheight; sizeheight += heightspeed)
sizer.resizeTo("1", sizeheight);
for (sizewidth = 1; sizewidth < winwidth; sizewidth += widthspeed)
sizer.resizeTo(sizewidth, sizeheight);
sizer.location = website;
}
else
window.open(website,'mywindow');
}
// End -->
</SCRIPT>
