  <tr>

  <td width="32" align="right"><img id=idface src="..../../../bbs/images/icon/1.gif" alt=个人形象代表 width="32" height="32"></td>

  <td width="30" ><font class=cha2>头像</font></td>

  <td width="69">

  <select class=editbox1 onChange="document.images['idface'].src=options[selectedIndex].value;">

  <option value=../../../bbs/images/icon/1.gif selected>头像1</option>

  <option value=../../../bbs/images/icon/2.gif select>头像2</option>

  <option value=../../../bbs/images/icon/3.gif select>头像3</option>

  <option value=../../../bbs/images/icon/6.gif select>头像6</option>

  <option value=../../../bbs/images/icon/7.gif select>头像7</option>

  <option value=../../../bbs/images/icon/8.gif select>头像8</option>

  <option value=../../../bbs/images/icon/9.gif select>头像9</option>

  <option value=../../../bbs/images/icon/10.gif select>头像10</option>

  <option value=../../../bbs/images/icon/11.gif select>头像11</option>

  <option value=../../../bbs/images/icon/12.gif select>头像12</option>

  <option value=../../../bbs/images/icon/13.gif select>头像13</option>

  <option value=../../../bbs/images/icon/15.gif select>头像15</option>

  </select>

  <td width="69">--> 静态</td>

  </tr>

  </table>

  ASP数组方法:将下面的代码复制到<body>~</body>内

  程序代码

  <table cellpadding="2" width="241" cellspacing="2" border="0" >

  <tr>

  <td width="32" align="right"><img id=idface1 src="..../../../bbs/images/icon/1.gif" alt=个人形象代表 width="32" height="32"></td>

  <td width="30" ><font class=cha2>头像</font></td>

  <td width="62">

  <select onChange="document.images['idface1'].src=options[selectedIndex].value;" class="editbox1" >

  <%

  dim i

  for i=1 to 20

  %>

  <option select value="../../../bbs/images/icon/<%=I%>.gif">头像<%=I%></option>

  <%

  next

  %>

  </select>

  </td>

  <td width="91"> --> ASP 数组 </td>

  </tr>

  </table>

  共同点:

  1、<img id=idface src="1.gif">                // 都必须在默认的图片上赋一个ID号

  2、<select onChange="document.images['idface'].src=options[selectedIndex].value;"> // 再在下拉菜单中调用这个ID

  ......

    </select>

  不同点:

  在静态的制作方法中:

  程序代码

  <select ......>

   <option value=1.gif > 头像1 </option>      // 直接在下拉菜单中的option选项中赋予路径

   <option value=2.gif > 头像2 </option>

   ......

  </select>

  --------------------------------------------------------------------------------

  在ASP数组 定义方法中:

  程序代码

  <select ......>

  <% dim i                           // 定义数组 i

    for i=1 to 20                        // 定义 i 的值为1~20

  %>

  <option select value="<%=I%>.gif">头像<%=I%></option>       // 显示第一条选项的值

  <% next %>                           // 下一条

  </select>
