var timer = null;
var alpha = 30;
function startMove(speed,iTarget){
clearInterval(timer);
var oDiv = document.getElementById('div1')
timer = setInterval(function(){

clearInterval(timer);
}?
else {

oDiv.style.opacity = alpha/100;

oDiv.onmouseover = function(){
startMove(10,100);
oDiv.onmouseout = function(){
? ? ? ? startMove(-10,30);
}
}
這里錯了? 沒{}對。應該是
oDiv.onmouseover = function(){
startMove(10,100);
}
oDiv.onmouseout = function(){
? ? ? ? startMove(-10,30);
}
