js定时器问题，接触定时器


function animate(obj, target, clink) {
    //清除以前的定时器,只保留一个定时器
    clearInterVal(obj.timer);
    obj.timer = setInterval(function () {
        if (obj.offsetLeft == target) {
            clearInterVal(obj.timer);
        }
        obj.style.left = obj.offsetLeft + 10 + 'px';
    }, 30)

    if (clink) {
        clink();
    }
}
