<html><head><title>div展开收缩代码</title><style>* { margin:0; padding:0;}body { text-align:center; font:75% Verdana, Arial, Helvetica, sans-serif;}h1 { font:125% Arial, Helvetica, sans-serif; text-align:left; font-weight:bolder; background:#333; padding:3px; display:block; color:#99CC00}.class1 { width:40%; background:#CCC; position:relative; margin:0 auto; padding:5px;}span { position:absolute; right:10px; top:8px; cursor: pointer; color:yellow;}p { text-align:left; line-height:20px; background:#333; padding:3px; margin-top:5px; color:#99CC00}#class1content, #class2content { height:300px;overflow:hidden;display:none;}</style><script>function $(element){return element = document.getElementById(element);}function $D(element){var d=$(element);var h=d.offsetHeight;var maxh=300;function dmove(){h+=50; //设置层展开的速度if(h>=maxh){d.style.height='300px';clearInterval(iIntervalId);}else{d.style.display='block';d.style.height=h+'px';}}iIntervalId=setInterval(dmove,2);}function $D2(element){var d=$(element);var h=d.offsetHeight;var maxh=300;function dmove(){h-=50;//设置层收缩的速度if(h<=0){d.style.display='none';clearInterval(iIntervalId);}else{d.style.height=h+'px';}}iIntervalId=setInterval(dmove,2);}function $use(targetid,objN){var d=$(targetid);var sb=$(objN); if (d.style.display=="block"){ $D2(targetid); d.style.display="none"; sb.innerHTML="展开"; } else { $D(targetid); d.style.display="block"; sb.innerHTML='收缩'; }}</script></head><body><div class="class1"> <h1>div展开收缩效果</h1> <span id="stateBut" onClick="$use('class1content','stateBut')">展开</span> <p id="class1content">something.........</p></div><div class="class1"> <h1>div展开收缩效果</h1> <span id="stateBut1" onClick="$use('class2content','stateBut1')">展开</span> <p id="class2content">something.........</p></div></body></html>
