scroll

[kilpin]

Vad är fel på detta script?

<script language="JavaScript">
<!--
var spd = 55, scroll_x = 0, scroll_y, scroll_destx = 0, scroll_desty = 0;

function kmh(destx,desty) {
scroll_destx = destx;
scroll_desty = desty;

while(scroll_destx != scroll_x) {
diff = scroll_destx - scroll_x;
if(scroll_destx < scroll_x) {
scr = Math.round((diff - spd) / spd);

while(scroll_desty != scroll_y) {
diff = scroll_desty - scroll_y;
if(scroll_desty < scroll_y) {
scr = Math.round((diff - spd) / spd);
}
}

} else
{
scr = Math.round((diff + spd) / spd);
}

scroll_x += scr;
scroll_y += scr;
parent.kommun.scrollTo(scroll_x,scroll_y);
}
}
