var xTempo = 5;
var yTempo = 5;
function init() {
height = getObj("box").offsetHeight;
width = getObj("box").offsetWidth;
startAnimation();
}
function startAnimation(){
setInterval("animate()",10);
}
function animate(){
if(x>=width){
xTempo = -5;
}
if(x<=0){
xTempo = 5;
}
if(y>=height){
yTempo = -5;
}
if(y<=0){
yTempo = 5;
}
x += xTempo;
y += yTempo;
shiftTo();
}
function shiftTo() {
getObj('rect').style.left = x + "px";
getObj('rect').style.top = y + "px";
}
function getObj(elementID){
return document.getElementById(elementID);
