本文实例讲述了jQuery实现侧浮窗与中浮窗切换效果的方法。分享给大家供大家参考，具体如下：
html部分：
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <title>浮动窗</title> </head> <body> <div style="height:3000px;"></div> <script type="text/javascript" src="library.js"></script> <script type="text/javascript" src="public.js"></script> </body> </html>
JS部分：
/*设置聊天窗口路径*/
var swt_url = '/zixun/';
/*侧边浮窗*/
var str = '<div id="swt_animation" style="display:none;">';
str += '<a class="close" onclick="close_swt('+"'swt_animation'"+');">X</a>';
