左右滚动问题

刚才给LZ发的代码没有兼容..只是IE ONLY
石头君的这个
是套了两层的.假如说内层是你的那个UL
它的宽度是可预料的(就是说固定的)所有LI的总长度.
然后
外层有DIV.
那个DIV设置hidden就可以了...

把石兄的自动滚动的setTimeout去掉就好了,下面是更改过的js,其他没动//从右到左
    this.scrollleft = function(){
        if(this.autoid!=null){
            window.clearTimeout(this.autoid);
        }
        var uvleft = this.scrollDOM.scrollLeft;
        uvleft += this.steplength;        this.scrollDOM.scrollLeft = uvleft;        if(uvleft>=this.uvwidth){
            this.scrollDOM.scrollLeft = 0;
        }        if(uvleft % this.showwidth == 0){
           // this.autoid = window.setTimeout(function(){dh.scrollleft()},dh.resttime);//==============自动滚动
        }else{
            this.autoid = window.setTimeout(function(){dh.scrollleft()},dh.steptime);
        }
        document.getElementById("s").innerHTML = this.uvwidth+","+uvleft;
    }    //从左到右
    this.scrollright = function(){
        if(this.autoid!=null){
            window.clearTimeout(this.autoid);
        }
        var uvleft = this.scrollDOM.scrollLeft;
        uvleft -= this.steplength;        this.scrollDOM.scrollLeft = uvleft;        if(uvleft <= 0){
            this.scrollDOM.scrollLeft = this.uvwidth;
        }        if(uvleft % this.showwidth == 0){
           // this.autoid = window.setTimeout(function(){dh.scrollright()},dh.resttime);//==============自动滚动
        }else{
            this.autoid = window.setTimeout(function(){dh.scrollright()},dh.steptime);
        }
        document.getElementById("s").innerHTML = this.uvwidth+","+uvleft;
    }
呵呵,不需要自动滚动的?那就如楼上说的吧setTimeout这个去掉就可以了
