回答1:

If you must have marquee functionality then try using a jQuery plugin such as simplyScroll v1 which supports continuous scrolling (ie. it seamlessly wraps around). Note, however, that marquees are considered bad for usability and accessibility in the same way the old <blink> tag was - see http://en.wikipedia.org/wiki/Marquee_element#Usability_problems

I believe this will help you:

 <script type="text/javascript" language="javascript">
    function objWidth(obj) {
        if (obj.offsetWidth) return obj.offsetWidth;
        if (obj.clip) return obj.clip.width;
        return 0;
    }
    var mqr = [];

    function mq(id) {
        this.mqo = document.getElementById(id);
        var wid = objWidth(this.mqo.getElementsByTagName('span')[0]) + 5;
        var fulwid = objWidth(this.mqo);
        var txt = this.mqo.getElementsByTagName('span')[0].innerHTML;
        this.mqo.innerHTML = '';
        var heit = this.mqo.style.height;
        this.mqo.onmouseout = function () {
            mqRotate(mqr);
        };
        this.mqo.onmouseover = function () {
            clearTimeout(mqr[0].TO);
        };
        this.mqo.ary = [];
        var maxw = Math.ceil(fulwid / wid) + 1;
        for (var i = 0; i < maxw; i++) {
            this.mqo.ary[i] = document.createElement('div');
            this.mqo.ary[i].innerHTML = txt;
            this.mqo.ary[i].style.position = 'absolute';
            this.mqo.ary[i].style.left = (wid * i) + 'px';
            this.mqo.ary[i].style.width = wid + 'px';
            this.mqo.ary[i].style.height = heit;
            this.mqo.appendChild(this.mqo.ary[i]);
        }
        mqr.push(this.mqo);
    }

    function mqRotate(mqr) {
        if (!mqr) return;
        for (var j = mqr.length - 1; j > -1; j--) {
            maxa = mqr[j].ary.length;
            for (var i = 0; i < maxa; i++) {
                var x = mqr[j].ary[i].style;
                x.left = (parseInt(x.left, 10) - 1) + 'px';
            }
            var y = mqr[j].ary[0].style;
            if (parseInt(y.left, 10) + parseInt(y.width, 10) < 0) {
                var z = mqr[j].ary.shift();
                z.style.left = (parseInt(z.style.left) + parseInt(z.style.width) * maxa) + 'px';
                mqr[j].ary.push(z);
            }
        }
        mqr[0].TO = setTimeout('mqRotate(mqr)', 10);
    }
 </script>

 <script type="text/javascript">
    function start() {
        new mq('m1');
        mqRotate(mqr);
    }

    window.onload = start;
 </script>

 <div id="m1" class="marquee">
    <span>Example for Continous Text</span>
 </div>

I believe this site has implementation that meets your requirement http://www.givainc.com/labs/marquee_example.htm

回答4:

If you want a news scroller you can try this plugin for jQuery liScroll, I don't know if you want to refresh the news without page reload?

回答5:

<asp:Literal ID="Literal1" runat="server"></asp:Literal>

Then you can give value for the literal.

protected void Page_Load(object sender, EventArgs e)
{
    string str = "get data from database";
    string text = "<MARQUEE>" + str + "</MARQUEE>";
    Literal1.Text = text;
}

I think this website is useful. http://www.dynamicdrive.com/dynamicindex2/
