二、jquery源碼:
代碼如下:
(function($){
$.fn.extend({
newsList:function(options){
var defaults ={
actName:'li', //顯示條數名；
maxShowNum:'6', //最多的顯示條數；
actNameH:'28', //一次移動的距離；
ulClass:'.ul_news_list', //被復制層的class
copyUlClass:'.ul_news_list2', //復制層的class
autoTime:'1500', //自動運行時間；
clickGoUpC:'.go_uplist', //點擊向上class;
clickDownUpC:'.go_downlist', //點擊向下class;
goStart:'go_tart',
autoCloss:'flase' //自動運行開關,當為'flase'時為開，其它則關；
} ;

options = $.extend(defaults, options);
return this.each(function(){
var o = options;
var counts =1;
var linum = $($(this).find(o.actName),$(this)).size();
var ul_class = $($(this).find(o.ulClass),$(this));
var copy_ul_class = $($(this).find(o.copyUlClass),$(this));
var click_go_up_c = $($(this).find(o.clickGoUpC),$(this));
var click_go_down_C = $($(this).find(o.clickDownUpC),$(this));
var go_start = $($(this).find(o.goStart),$(this));
if(linum > o.maxShowNum){
$(copy_ul_class).html($(ul_class).html());
goStartList();
}
var thiswrap = $($(ul_class).parent().parent(),$(this));
//自動運行函數
function auto_function(){
if(counts <= linum){
$(ul_class).animate({top:'-=' + o.actNameH},o.autoTime);
$(copy_ul_class).animate({top:'-=' + o.actNameH},o.autoTime);
counts++;
}else{
$(ul_class).animate({top:0},0);
$(copy_ul_class).animate({top:0},0);
counts = 1;
}
}
//點擊向上移動時；
if(linum > o.maxShowNum){
$(click_go_up_c).click(function(){
if(counts <= linum){
$(ul_class).animate({top:'-=' + o.actNameH},0);
$(copy_ul_class).animate({top:'-=' + o.actNameH},0);
counts++;
}else{
$(ul_class).animate({top:0},0);
$(copy_ul_class).animate({top:0},0);
counts = 1;
}
});
}
//點擊向下移動時；
if(linum > o.maxShowNum){
$(click_go_down_C).click(function(){
if(counts > 1){
counts--;
$(ul_class).animate({top:'-'+ counts*o.actNameH},0);
$(copy_ul_class).animate({top:'-'+ counts*o.actNameH},0);
}else{
$(ul_class).animate({top:0},0);
$(copy_ul_class).animate({top:0},0);
counts = linum+1;
}
});
}
//鼠標經過所發生的開始停止；
if(linum > o.maxShowNum){
$(thiswrap).hover(function(){
goStopList();
},function(){
goStartList();
});
}
function goStartList(){
if(o.autoCloss === 'flase'){
go_start = setInterval(auto_function,o.autoTime);
}
}
function goStopList(){
clearInterval(go_start);
}
});
}
});
}(jQuery));

三、HTML:
代碼如下:
<script language="javascript">
$(document).ready(function(){
$("#newslist").newsList();
});
</script>
