ASP數組方法：將下面的代碼復制到<body>~</body>內
程序代碼
<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=個人形象代表 width="32" height="32"></td>
<td width="30" ><font class=cha2>頭像</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">頭像<%=I%></option>
<%
next
%>
</select>
</td>
<td width="91"> --> ASP 數組 </td>
</tr>
</table>
共同點：
1、<img id=idface src="1.gif"> // 都必須在默認的圖片上賦一個ID號
2、<select onChange="document.images['idface'].src=options[selectedIndex].value;"> // 再在下拉菜單中調用這個ID
......
</select>
不同點：
在靜態(tài)的制作方法中：
程序代碼
<select ......>
<option value=1.gif > 頭像1 </option> // 直接在下拉菜單中的option選項中賦予路徑
<option value=2.gif > 頭像2 </option>
......
</select>
--------------------------------------------------------------------------------
在ASP數組 定義方法中：
程序代碼
<select ......>
<% dim i // 定義數組 i
for i=1 to 20 // 定義 i 的值為1~20
%>
<option select value="<%=I%>.gif">頭像<%=I%></option> // 顯示第一條選項的值
<% next %> // 下一條
</select>
