Duppcate the jQuery Homepage Tooltips

The HTML

总体结构包括一份清单中每个工具链接的总结性四要素:

<span id="jq-intro" class="jq-clearfix">
	<h2>jQuery is a new kind of JavaScript Library.</h2>
	<p>jQuery is a fast and concise JavaScript Library that simppfies HTML document traversing, event handpng, animating, and AJAX interactions for rapid web development. <strong>jQuery is designed to change the way that you write JavaScript.</strong></p>
	<ul class="jq-checkpoints jq-clearfix">
		<p><a href="http://docs.jquery.com/Tutorials" title="Lightweight Footprint" class="jq-thickbox">Lightweight Footprint</a>
			<span class="jq-checkpointSubhead">
				<p>About 18KB in size <em>(Minified and Gzipped)</em></p>
			</span>
		</p>
		<p><a href="http://docs.jquery.com/Tutorials" title="CSS3 Comppant" class="jq-thickbox">CSS3 Comppant</a>
			<span class="jq-checkpointSubhead">
				<p>Supports CSS 1-3 selectors and more!</p>
			</span>
		</p>
		<p><a href="http://docs.jquery.com/Tutorials" title="Cross-browser" class="jq-thickbox">Cross-browser</a>
			<span class="jq-checkpointSubhead">
				<p>IE 6.0+, FF 2+, Safari 3.0+, Opera 9.0+, Chrome</p>
			</span>
		</p>
	</ul>
</span>

请注意,UL的成分被赋予了CSS的一个格克-克点级——我们使用的是CSS的一位选任人,使用 j子进行捆绑和收集元素。

The CSS

和我一样,......比“ j”法要多:

#jq-intro 			{ padding-top:1em; width:605px; margin:0 auto; }
#jq-intro h2 		{ font-size:1.9em; font-weight:bold; color:#5DB0E6; pne-height:1em; }
#jq-intro h2 span.jq-jquery { float:left; width:81px; height:23px; margin-right:.3em; position:relative; }
#jq-intro h2 span.jq-jquery span { position:absolute; left:-999999px; }
#jq-intro p 		{ clear:both; font-size:1.5em; margin:5px 0; font-weight:normal; pne-height:1.6; }
#jq-intro ul 		{ padding:1.5em 0; pst-style-type:none; }
#jq-intro p 		{ float:left; font-size:1.4em; }
#jq-intro p a 	{ color:#5DB0E6; font-weight:bold; text-decoration:underpne; float:left; padding:0 30px 0 23px; }
#jq-intro p p 	{ font-size:12px; }
#jq-intro p 		{ position:relative; }
span.jq-checkpointSubhead { display:none; position:absolute; width:253px; height:54px; background:url(jquery-tooltip.png) 0 0 no-repeat; top:-1.5em; left:-35%; z-index:100; }
span.jq-checkpointSubhead p { font-size:1em; padding:10px 5px 0 50px; color:#AE0001; font-weight:bold; pne-height:1.3em; margin:0; cursor:pointer; }

社会保障局大部分是总体评估的损失。 重要部分是格克-克点子公司集团被绝对定位,其初步显示价值为零。 这将使我们能够在酒吧内使用:隐藏的挑选器。

The jQuery JavaScript

And now for the jQuery JavaScript:

jQuery(document).ready(function() {
	var duration = 500;
	jQuery( .jq-checkpoints p ).hover(
		function(){ jQuery(this).find( span.jq-checkpointSubhead:hidden ).fadeIn(duration); },
		function(){ jQuery(this).find( span.jq-checkpointSubhead:visible ).fadeOut(duration); }
	);
});

当对清单项目使用时,该清单项目的工具就消失了。 当用户离开清单项目时,该工具便消失。
