怎么把select下拉菜單里的文字設(shè)置成左右滾動(dòng)效果

字號(hào):


    希望用marquee標(biāo)簽來(lái)設(shè)置字體滾動(dòng),代碼是下面這樣寫的,但是沒有效果,字體還是不會(huì)滾動(dòng),應(yīng)該怎么來(lái)寫,才會(huì)實(shí)現(xiàn)這個(gè)效果呢?
    <html:select property=”w_project_cd[]” value=”<%=prj.toString()%>” onchange=”<%=js.toString()%>” style=”width:260px”>
    <logic:notEmpty name=”proj_list”>
    <marquee direction=”left” behavior=”scroll” scrollamount=”10″ scrolldelay=”200″> <html:options collection=”proj_list” property=”value” labelProperty=”label”/></marquee>
    </logic:notEmpty>
    </html:select>
    在網(wǎng)上找到了一個(gè)類似的例子,如下詳細(xì)的代碼:
    HTML code:
    代碼如下:
    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
    <html xmlns="http://www.w3.org/1999/xhtml">
    <head>
    <meta http-equiv="Content-Type" content="text/html; charset=gb2312" />
    <title>無(wú)標(biāo)題文檔</title>
    <script type="text/javascript">
    function init(){
    var os=document.getElementsByTagName("option");
    for(var i=0;i<os.length;i++){
    var tx=os[i].innerHTML;
    var l=tx.length;
    var b=tx.substring(0,1);
    var e=tx.substring(1);
    os[i].innerHTML=e+b;
    }
    window.setTimeout(init,1000);
    }
    window.onload=init;
    </script>
    </head>
    <body>
    <select>
    <option>一個(gè)用法</option>
    <option>也許人生就是如此</option>
    <option>云在青天,水在瓶</option>
    </select>
    </body>
    </html>
