效果如下图：当点击问题时显示下面的回复内容。复制代码 代码如下:script type="text/javascript"> onload = function(){ faq(document.getElementsByTagName("dl")[0], "dt", "dd"); /* * faq函数：elem是父元素，qTag是标题元素，aTag是内容元素 */ } function faq(elem, qTag, aTag){ aTag = aTag || "dd"; //提供默认值，下同 qTag = qTag || "dt"; elem = elem || document; var dds = elem.getElementsByTagName(aTag); for (var i = 0, len = dds.length; i < len; i++) { dds[i].style.display = "none"; } var dts = elem.getElementsByTagName(qTag); for (var i = 0, len = dts.length; i < len; i++) { dts[i].style.cursor = "hand"; dts[i].onclick = function(){ var next = this.nextSibling; //获得当前元素的下一个元素的引用 while (next.nodeType != 1) { next = next.nextSibling; } if (next.style.display != "none") { next.style.display = "none"; } else { next.style.display = "block"; } } } } </script> 测试代码： Untitled Document dd { background: #eee; border: 1px solid #ccc; margin-left: 2px; padding: 4px; } One question:What are ready to do? What I want to do is you,do you understand my feeling to you. I hope you are the same to me. Two questing:What do you want? I want to see you now,I miss you so much,I want to see you at this moment. Three question:Do you want to have a girlfriend? I think everyone want it so much,me too,I want to have someone talk to me everyday. [Ctrl+A 全选 注:如需引入外部Js需刷新才能执行]
