scroll_img.js如下：
function scroll_img(target,distance,show_width,li_width,mr){ this.distance=distance; //每次移动距离 this.target=$(#+target); this.show_width=show_width; //显示区域宽度 this.li_width=li_width; //items宽度 this.mr=mr; //items间距 this.scrollbar=$(#+target).find('ul'); this.position=0; this.direction=1;}scroll_img.prototype={ version:1.00, author:yangfeifei, date:2011-11-21, initialize:function(){ var t=this; t.scrollbar.css('position','relative'); //初始动作 t.autoplay(); t.scrollbar.mouseover(function(){t.stop();}); //鼠标移到图片上停止自动播放 t.scrollbar.mouseout(function(){t.autoplay();}); //鼠标移出图片开始自动播放 }, right:function(){ var t=this; (-t.position)0){ t.scrollbar.animate({left:t.position},500); t.direction=-1; } if((-t.position)==0){ t.scrollbar.animate({left:t.position},500); t.direction=1; } }, total_length:function(){ var t=this, total_num=t.scrollbar.find('li').length; return total_num*(t.li_width+t.mr)-(t.mr+t.show_width); }, autoplay:function(){ var t=this; t.setint=setinterval(function(){ t.direction==1?t.right():t.left(); },3000); }, stop:function(){ var t=this; clearinterval(t.setint); }}
global.css如下：
/*css reset*/body,div,dl,dt,dd,ul,ol,li,h1,h2,h3,h4,h5,h6,pre,form,fieldset,input,textarea,p,blockquote,th,td{margin:0;padding:0;font-family:arial,宋体;}table{border-collapse:collapse;border-spacing:0;}fieldset,img{border:0;}address,caption,cite,code,dfn,em,strong,th,var{font-style:normal;font-weight:bold;}ol,ul{list-style-type:none;}caption,th{text-align:left;}h1,h2,h3,h4,h5,h6{font-size:100%;font-weight:normal;}/*font-size:100%;的作用主要是改变它默认的大小，继承父体的字体大小*/q:before,q:after{content:' ';}abbr,acronym{border:0;}.cb{clear:both;}.cl{clear:left;}.cr{clear:right;}.clearfix:after{content:.;display:block;height:0;clear:both;visibility:hidden;}.clearfix{display:inline-block;}* html .clearfix{height:1%;}.clearfix{display:block;}/*主体css*/.scroll_img_wrap{width:612px;margin: 10px auto;} #scroll_img{width:590px;overflow:hidden;float:left;*position:relative;border: 1px #ccc solid;}/*可视区域宽度*/ .scroll_img_list{width:9999px;} .scroll_img_list li{float:left;width:140px;margin-right:10px;}/*items*/ .scroll_img_list li p{text-align:center;} .scroll_img_list li p a{text-decoration:none;color:#666;} .left_btn,.right_btn{float:left;}
希望本文所述对大家的javascript程序设计有所帮助。
