分享这样的表单怎样验证?
同一个表单中有n(n>=1)个年度字段intYear,类型为下拉列表框
如
<select name=intYear1 id=intYear1>
<option value=2003>2003</option>
<option value=2002>2002</option>
...
<option value=1980>1980</option>
</select>
<select name=intYear2 id=intYear2>
<option value=2003>2003</option>
<option value=2002>2002</option>
...
<option value=1980>1980</option>
<option value=1995>1995</option>
</select>
......
<select name=intYearn id=intYearn>
<option value=2003>2003</option>
<option value=2002>2002</option>
...
<option value=1980>1980</option>
</select>
怎样进行验证(客户端,javascript)才能保证这n个字段所选的年份值不一样？
如
<select name=intYear1 id=intYear1>
<option value=2003>2003</option>
<option value=2002>2002</option>
...
<option value=1980>1980</option>
</select>
<select name=intYear2 id=intYear2>
<option value=2003>2003</option>
<option value=2002>2002</option>
...
<option value=1980>1980</option>
<option value=1995>1995</option>
</select>
......
<select name=intYearn id=intYearn>
