转自:http://www.sosuo8.com/article-2010/js-tip-tips-to-achieve-results-without-picture.htm

示例:http://www.sosuo8.com/article-2010/js-tip-tips-to-achieve-results-without-picture.htm

网页提示是可以直接用title提示的,但是如果要实现个性化的title提示效果,就必须借助javascritp。jelle同学写的这个提示效果,体积小,且不用图片,值得推荐!

<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})};
