<!doctype html>

//上面定义出一个样式 </head> <body> <div id="dd"> <div class="nkk" style="background: red" onClick="Ca('uu')">军事</div> <div class="nkk" style="background: green;" onClick="Ca('uk')">新闻</div> <div class="nkk" style="background: blue;" onClick="Ca('un')">理论</div> </div>
//这上面先写出三个标题 <div class="ijj" id="uu" style="background: red"></div> <div class="ijj" id="uk" style="background: green;display: none"></div> <div class="ijj" id="un" style="background: blue;display: none"></div>
//这写出三个选项卡 </body> <script type="text/javascript">//然后开始写js 部分 function Ca(a) { var pp = document.getElementById(a) var div = document.getElementsByClassName("ijj")//找定义 for(i=0;i<div.length;i++) { div[i].style.display= "none"; } pp.style.display= "block"; } </script> </html>

  

这是一个选项卡的效果,他随着标题的变换而变换
