效果如图：

代码如下：

<title>悬浮窗口示例</title> <script type="text/javascript"> window.onscroll = function () { var div = document.getElementById("divSuspended"); div.style.top = document.body.scrollTop; } window.onresize = window.onscroll; function init(){ var df = document.createDocumentFragment(); for(var i=0;i<20;i++){ var p = document.createElement("p"); p.appendChild(document.createTextNode(" Line "+i)); df.appendChild(p); } document.body.appendChild(df); window.onscroll(); } </script> <p>Try scrolling this window.</p> <div id="divSuspended" style="position: absolute; buttom: 0px; right: 0px; color: #cccccc; width: 150px; height: 30px; background-color: navy">这是悬浮窗口</div>
