blank.jsp页面有代码:
<form name="frm">
<select name="s1" onChange="redirec(document.frm.s1.options.selectedIndex)">
<option selected>选择部门</option>
<option value="1">信息部</option>
<option value="2">人事部</option>
<option value="3">物业部</option>
</select>
<select name="s2">
<option value="请选择" selected>请选择</option>
</select>
<jsp:useBean id="present" class="xxb.date.DateBean" scope="page"/>
<input name="date" class="editbox4" value="<%=present.today("yyyy-MM-dd")%>" size="20">
</form>
<script language="javascript">
//获取一级菜单长度
var select1_len = document.frm.s1.options.length;
var select2 = new Array(select1_len);
//把一级菜单都设为数组
for (i=0; i<select1_len; i++)
{
select2[i] = new Array();
}
//定义基本选项
