<style type="text/css">
div.xx{border:solid 0px;overflow:hidden;}
div.xx h5{border:solid 0px;border-width:0 0 0px;padding:0;margin:0;height:28px;line-height:30px;cursor:pointer;background:#eee;}

</head>
<body>
<div class="xx"><h5 onclick="toggle(this.parentNode)">点击此处层伸缩</h5>
<p>test</p>
</div>
</body>
文字点击展开效果,可如让文字默认是收缩着的呢?求达人教教我吧~谢谢...
