jquery header single line information scrolling display implementation ideas and code_jquery

The following is the style to control scrolling. Query the scrolling content and put it in a div or other container. What I use here is

<style>
#newCglist{width:300px;height:14px;line-height:14px;overflow:hidden}
#newCglist li{height:14px;padding-left:10px;}
</style>

The following is a container for scrolling content display

<dt class="positionrel" id="newCglist" ><div class="new positionabs"></div></dt>

The following is js to query the scrolling display content

var divhight ; //这是所有数据行的高度，每行行高*数据量
var showtimes ; //显示完所有数据的时间，每行显示所需的时间*数据量

function yejis(){
setInterval('AutoScroll("#newCglist")',500);
//最新成交案例展示
$.post("zrAction!newCgList.action",null,function(data){
divhight = data.length*14;
showtimes = data.length*3000;
$.each(data,function(i,datas){
$ul = $("<ul></ul>");
$tr = $("<li>"+datas[0]+" 签单成功！ "+datas[1]+"元 "+datas[2]+" "+datas[3]+"</li>");
$ul.append($tr);
$("#newCglist").append($ul);
});
});

The following is to control the scrolling display time and style

/**
* 首页顶部滚动效果，divhight 是所有数据的行高
* showtimes //循环滚动完这些数据所需的时间
* @param {Object} obj
* @memberOf {TypeName} 
*/
function AutoScroll(obj){
$(obj).find("ul:first").animate({
marginTop:-divhight
},showtimes,function(){
$(this).css({marginTop:"0px"}).find("li:first").appendTo(this);
});
}
