                                            <%#Eval("UserName").ToString().Length>2?Eval("UserName").ToString().Remove(Eval("UserName").ToString().Length-2,2)+"**":"**" %></span>
                                            获得 <span class="color03">
                                                <%#Eval("ObjType").ToString()=="1"?"土地币"+Eval("SFB").ToString()+"个":"土地投融资查看权限(一周)" %></span></li></ItemTemplate>

                    var FGDemo_ = document.getElementById("demo_");
                    var FGDemo1_ = document.getElementById('demo1_');
                    var FGDemo2_ = document.getElementById('demo2_');
                    FGDemo2_.innerHTML = FGDemo1_.innerHTML;
                    function Marquee1_() {
                        if (FGDemo2_.offsetHeight - FGDemo_.scrollTop <= 0) {
                            FGDemo_.scrollTop -= FGDemo1_.offsetHeight;
                        }
                        else {
                            FGDemo_.scrollTop++;
                        }
                    }
                    var MyMar1_ = setInterval("Marquee1_()", speed_);
                    FGDemo_.onmouseover = function() { clearInterval(MyMar1_) }

Answer 1

你的两个都不行
看这个<div id="demo">
        <div id="demo1">
            <a href="#"><img src="http://www.cnrui.cn/other/link/Clear_logo.gif" border="0" alt=""/></a>
            <a href="#"><img src="http://www.cnrui.cn/other/link/Clear_logo.gif" border="1" alt=""/></a>
            <a href="#"><img src="http://www.cnrui.cn/other/link/Clear_logo.gif" border="2" alt=""/></a>
            <a href="#"><img src="http://www.cnrui.cn/other/link/Clear_logo.gif" border="3" alt=""/></a>
        </div>
        <div id="demo2">
        </div>
    </div>    <script type="text/javascript">
        <!--
        var speed=10; //数字越大速度越慢
        var tab=document.getElementById("demo");
        var tab1=document.getElementById("demo1");
        var tab2=document.getElementById("demo2");
        tab2.innerHTML = tab1.innerHTML; //克隆demo1为demo2        function Marquee(){
            if (tab2.offsetTop - tab.scrollTop <= 0)//当滚动至demo1与demo2交界时
                tab.scrollTop -= tab1.offsetHeight; //demo跳到最顶端
            else
                tab.scrollTop++;
        }
        var MyMar=setInterval(Marquee,speed);
        tab.onmouseover=function() {clearInterval(MyMar)};//鼠标移上时清除定时器达到滚动停止的目的
        tab.onmouseout=function() {MyMar=setInterval(Marquee,speed)};//鼠标移开时重设定时器
        -->
    </script>

Answer 2

自己解决了。到样式中加个overflow:hidden就OK了
