clearTimeout怎么用

[托泥羊]

下面这个函数怎么结束掉setTimeout？？

function moveToTop(classNa,distenceInit,distence,speed)
{
console.debug("start......");
element=document.getElementsByClassName(classNa)[0];
var topTemp=parseInt(element.style.top);
console.debug("topTemp:"+topTemp);

if (topTemp <= (distenceInit - distence)) {
clearTimeout(t); //——这个怎么不起作用啊？？？
console.debug("end if,truely end......");
} else {
topTemp--;
element.style.top = topTemp + "px";
}
var repeat = "moveToTop('" + classNa + "'," + distenceInit + "," + distence + "," + speed + ")";
t = setTimeout(repeat, speed);

}

而且不用clearTimeout都行了。。主要是你最后那句导致计时器重新开始了 if (topTemp <= (distenceInit - distence)) { return }

用于清除定时的id

if (topTemp <= (distenceInit - distence)) { clearTimeout(t); //——这个怎么不起作用啊？？？ console.debug("end if,truely end......"); return } 结束执行，要不后面的 t = setTimeout(repeat, speed);又执行了
