<h2>优点</h2> 
<ul> 
<li>1：兼容 各种浏览器</li> 
<li>2：自己定义TIPS样式(颜色),CSS3渐进增强</li> 
<li>3：多方向弹出提示</li> 
<li>4：纯CSS+javascript(不包含任何图片)</li> 
<li>5：体积超级小 CSS+js = 3k</li> 
</ul> 
<h2>参数配置</h2> 
<ul> 
<li>ljtips(object).show(JSON)</li> 
<li>object: DOM对象ID(test1), DOM对象</li> 
<li><pre> 
json:{ 
content:提示的消息内容(必须), 
p:提示框位置(可选值top left bottom right),默认为right(可选), 
closeBtn:是否有关闭按钮(true false) 默认值(false)(可选), 
time:多少毫秒提示框消失(可选) 
} 
</pre></li> 
</ul> 
<h3>使用说明</h3> 
<ul> 
<li>主要方法 .show(); .hide();.clear(); 一般你只需要使用show,hide;</li> 
<li>使用1</li> 
<li>首先实例化一个ljtips(var tips=ljtips('test1')); 然后使用tips.show(JSON)</li> 
<li>使用2</li> 
<li>在行内调用提示框"<div onclick=" ljtips(this).show(JSON); "></div>"</li> 
<li>使用3</li> 
<li>在JS里调用document.getElementById("test6").onmouseover = function(){ljtips(this).show({content:"这个框你关不掉了吧！没有关闭按钮！",p:'right'})};</li> 
</ul> 
 
</body>
