jquery对联广告

话不多说了，jquery对联广告插件，支持载fash和图片。

原理很简单，就是浮动 position:absolute,可关闭

//调用方法
//$("body").couplet({100,height:300,leftCouplet:"http://www.youzhuang.net/ad/left.swf",rightCouplet:"http://www.youzhuang.net/ad/right.swf"});});
//调用参数
//100,--宽 默认宽度100
//height:300,--总高 默认高度 300
//top:100,广告距顶部的高度
//leftCouplet:"http://www.youzhuang.net/ad/left.swf",左则flash地址或图片地址
//leftLink:"http://www.youzhuang.net/",左则连接地址，广告是图片时需要
//rightCouplet:"http://www.youzhuang.net/ad/right.swf",右则flash地址或图片地址
//rightLink:"http://www.youzhuang.net/"右则连接地址，广告是图片时需要

jQuery.fn.couplet = function(settings) {  
             
            settings = jQuery.extend({
                 100,
                height:300,
                top:100,
                leftCouplet:"",
                leftLink:"http://www.youzhuang.net/",
                rightCouplet:"",
                rightLink:"http://www.youzhuang.net/"
            },
            settings);
            var s = this;
            //添加广告窗口
           s.append("<div class=\"couplet\" id=\"leftCouplet\" style=\""+settings.width+";left:10px;top:0px; position:absolute;background:#e5e5e5;\"></div>");
           s.append("<div class=\"couplet\" id=\"rightCouplet\" style=\""+settings.width+";right:10px;top:0px; position:absolute;background:#e5e5e5;\"></div>");
           var leftCouplet = s.children("#leftCouplet");
           var rightCouplet = s.children("#rightCouplet");
           //加载左则广告
           if(settings.leftCouplet.substring(settings.leftCouplet.lastIndexOf('.')).toLowerCase() == ".swf"){
               leftCouplet.append("<embed src=\"" + settings.leftCouplet + "\" width=\"" + settings.width + "\" height=\"" + settings.height + "\" </embed>");
           }else{

           }
           //加载右则广告
           if(settings.rightCouplet.substring(settings.rightCouplet.lastIndexOf('.')).toLowerCase() == ".swf"){
               rightCouplet.append("<embed src=\"" + settings.rightCouplet + "\" width=\"" + settings.width + "\" height=\"" + settings.height + "\" </embed>");
           }else{
                rightCouplet.append("<a href='"+settings.rightLink+"' target='_blank'><img src=\""+settings.rightCouplet+"\" width=\""+settings.width+"\"  height=\""+settings.height+"\"/></a>");
           }

           var closeBtn = "<div class=\"coupletClose\" style=\"text-align:center;padding:2px 0px;font-size:12px;cursor:pointer \">关闭</label>";
           leftCouplet.append(closeBtn);
           rightCouplet.append(closeBtn);
           $(".coupletClose").click(function(){
               leftCouplet.remove(); 
               rightCouplet.remove(); 
           });

           //显示对联
            show();
            
            function show(){
                var winTop = $(window).scrollTop();
                $(".couplet").animate({
                   top: winTop + settings.top
                 }, 300);
              
            };
            //滚动条事件
            $(window).scroll(function() {
