<span style="display:inline-block; padding:5px; border:1px solid #CCC; margin:30px 30px 30px 100px;" id="test3">提示在我的下面出现</span><br>

<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> 
<script type="text/javascript"> 
var test1 = ljtips('test1'); 
document.getElementById("test1").onmouseover = function(){test1.show({content:"鼠标划过时候的TIPS...<br>兼容主流浏览器 IE 6 7 8 chorme Firefox Opera Safari"})}; 
document.getElementById("test1").onmouseout = function(){test1.hide();}; 
document.getElementById("test2").onfocus = function(){ljtips(this).show({content:"这个提示会在<br>input的上方！有个关闭按钮哦",p:'top',closeBtn:true})}; 
document.getElementById("test3").onmouseover = function(){ljtips(this).show({content:"我在下面出现了！不要认为会用到图片哦！",p:'bottom',closeBtn:true})}; 
document.getElementById("test4").onmouseover = function(){ljtips(this).show({content:"我可以在4个方向上",p:'left',closeBtn:true})}; 
document.getElementById("test5").onmouseover = function(){ljtips(this).show({content:"提示出现2秒后会自动消失",p:'bottom',time:2000})}; 
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'})}; 
document.getElementById("test7").onmouseover = function(){ljtips(this).show({content:"您可以放大或者缩小浏览器窗口！<br>他会跟随这个绝对位置,不会有丝毫偏差。",p:'right',closeBtn:true})}; 
</script>
