静态方法：将下面的代码复制到<body>~</body>内 程序代码
<table cellpadding="2" width="226" cellspacing="2" border="0" >
<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/4.gif select>头像4</option>
<option value=../../../bbs/images/icon/5.gif select>头像5</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/14.gif select>头像14</option>
<option value=../../../bbs/images/icon/15.gif select>头像15</option>
<option value=../../../bbs/images/icon/16.gif select>头像16</option>
<option value=../../../bbs/images/icon/17.gif select>头像17</option>
<option value=../../../bbs/images/icon/18.gif select>头像18</option>
<option value=../../../bbs/images/icon/19.gif select>头像19</option>
<option value=../../../bbs/images/icon/20.gif select>头像20</option>
</select>
</td>
<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>
