  开始

  为了做这个yahoo搜索框,我分了三步:

  1. 先做搜索分类的按钮,点击后会和其他按钮看上去比较不一样,这个是挺简单的

  <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
  <html xmlns="http://www.w3.org/1999/xhtml">
  <head>
  <title>search_bar</title>
  <meta http-equiv="Content-Type" content="text/html; charset=gb2312" />
  <style>
  body,html {
  font-size:12px;
  }
  .none {display: none;}
  .block {display: block;}
  .s_c {width:800px;text-align: center;}
  .s_c ul{clear:both;margin:0;}
  .s_c li{list-style:none;float:left;position: relative;width: 70px;}
  .c_0 {padding:0px 10px 0px 10px;line-height:22px}
  .c_0 a{color:#666;text-decoration: none;}
  .c_1 {padding:4px 0;width: 70px;
  background:#0075eb;border:1px solid #054576;border-bottom-width:0;text-decoration: none;}
  .c_1 a{color:#FFF;font-weight:bold;text-decoration: none;}
  .c_2 {padding:4px 0;width: 70px;background:#a10303;border:1px solid #662626;border-bottom-width:0;}
  position: absolute;bottom: -7px;left: 0;}
  .c_3 {padding:4px 0;width: 70px;background:#B01FAA;border:1px solid #760473;border-bottom-width:0;}
  .white a {color:#FFF;font-weight:bold;text-decoration: none;}
  </style>
  <script language="javascript">
  function aa(s_id){
  for(i=1;i<4;i ){
  if(i==s_id){
  document.getElementById("m" i).className="c_" i " white";
  }
  else {
  document.getElementById("m" i).className="c_0";
  }
  }
  }
  </script>
  </head>
  <body>
  <div class="s_c"><ul>
  <li><div id="m1" class="c_1"><a href="###" onClick="aa(’1’)">分类第一</a></div></li>
  <li><div id="m2" class="c_0"><a href="###" onClick="aa(’2’)">分类第二</a></div></li>
  <li><div id="m3" class="c_0"><a href="###" onClick="aa(’3’)">分类第三</a></div></li>
  </ul>
  </div>
  </body>
  </html>

  当然这还不够,接下来实现第二步效果。

  2.加个搜索输入框,而且要能换颜色的

  <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
  <html xmlns="http://www.w3.org/1999/xhtml">

  <title>search_bar</title>
  <meta http-equiv="Content-Type" content="text/html; charset=gb2312" />
  <style>
  body,html {
  font-size:12px;
  }
  .none {display: none;}
  .block {display: block;}
  .s_c {width:800px;text-align: center;}
  .s_c ul{clear:both;margin:0;}
  .s_c li{list-style:none;float:left;position: relative;width: 70px;}
  .s_b {border:1px solid #666;}
  .s_b span{padding:20px 20px;vertical-align:middle;}
  .s_b input{margin:8px 8px;}
  .search_0 {background:#fff;}
  .search_1 {background:#d2e4fc;}
  .search_2 {background:#fcd2d2;}
  .search_3 {background:#F9D3FA;}
  .search_4 {background:#defbfb;}
  .search_5 {background:#fce8d2;}
  .search_6 {background:#FCEBB9;}
  .c_0 {padding:0px 10px 0px 10px;line-height:22px}
  .c_0 a{color:#666;text-decoration: none;}
  .c_1 {padding:4px 0;width: 70px;
  background:#0075eb;border:1px solid #054576;border-bottom-width:0;text-decoration: none;}
  .c_1 a{color:#FFF;font-weight:bold;text-decoration: none;}
  .c_2 {padding:4px 0;width: 70px;background:#a10303;border:1px solid #662626;border-bottom-width:0;}
  position: absolute;bottom: -7px;left: 0;}
  .c_3 {padding:4px 0;width: 70px;background:#B01FAA;border:1px solid #760473;border-bottom-width:0;}
  .white a {color:#FFF;font-weight:bold;text-decoration: none;}
  </style>
  <script language="javascript">
  function aa(s_id){
  for(i=1;i<4;i ){
  if(i==s_id){
  document.getElementById("s" i).className="block be";
  document.getElementById("m" i).className="c_" i " white";
  document.getElementById("uid_" i).focus();
  }
  else {
  document.getElementById("s" i).className="none";
  document.getElementById("m" i).className="c_0";
  }
  }
  }
  </script>
  </head>
  <body>
  <div class="s_c"><ul>
  <li><div id="m1" class="c_1"><a href="###" onClick="aa(’1’)">分类第一</a></div></li>
  <li><div id="m2" class="c_0"><a href="###" onClick="aa(’2’)">分类第二</a></div></li>
  <li><div id="m3" class="c_0"><a href="###" onClick="aa(’3’)">分类第三</a></div></li>
  </ul>
  </div>
  <div class="s_b">
  <div class="block" id="s1"><div class="search_1"><span>Search the Web:</span><input name="uid" id="uid_1" /><span>按钮</span></div></div>
  <div class="none" id="s2"><div class="search_2"><span>Search the Web:</span><input name="uid" id="uid_2" /><span>按钮</span></div></div>
  <div class="none" id="s3"><div class="search_3"><span>Search the Web:</span><input name="uid" id="uid_3" /><span>按钮</span></div></div>
  </div>
  </body>
  </html>
