ASP数组方法将狼蚁网站SEO优化的代码复制到<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>
