为了作漂亮的气球信息提示框以替换HTML标签中的title属性，BeautyTips (基于jquery的一个插件)完成了这一想法javascript
http://www.lullabot.com/files/bt/bt-latest/DEMO/index.htmlhtml
这是demo,蛮漂亮的,在开发过程当中有两个重要设置不要忽略了：java
jQuery.bt.options.ajaxLoading = '<img src="/images/throbber.gif" width="40" height="40" />';//若是作ajax气球框，那么在interactive这段时间显示一个加载图片以给用户友好提示正在交互信息
jQuery.bt.options.closeWhenOthersOpen = true;//顾名思义，当打开一个气球的时候其余气球都关闭，这个若是不设置的话页面上会弹出不少气球框，让人很烦。。jquery
http://plugins.jquery.com/project/bt,这是jquery BT的介绍,有一点要说明一下,这个效果是基于HTML5标准的(使用到canvas 元素),因为IE浏览器不支持此标签,因此要额外添加一个js库excanvas.jsajax
另外在demo页面会看到以下一段话：json
BeautyTips has been tested with jQuery 1.2.6 and 1.3 on Firefox 3.x, Safari 3.x (also works on iPhone!), IE 6.x+, and Opera 8+, but I'm sure other canvas-capable browsers will work as well.canvas
测试时jquery的版本是1.2.6和1.3.x的，不过本人测试jquery1.4.2也是能够用的浏览器
下边是个小例子:ide
