select下拉列表选项赋值的问题

老实讲,你说的不是很明白.
这样加option:
var oOption = document.createElement("OPTION");
oOption.text = "页面可看到的label";
oOption.value = "value";
document.all.deb_in_line_slt.add(oOption);
如果要付值,找到option 对象.用oOption.text = "页面可看到的label";oOption.value = "value";来付值就可以.
document.all.deb_in_line_slt.options得到的是option集合,是个对象数组.

</form>如上的form，这段代码，当用户选择部门后，会自动将值赋给部门人数那个框。可问题是，这样在提交本页面后，deb_addi_chek.php获得的$deb_in_quan的值也是人数的值，而不是这个部门。因此，我希望在部门选择这个列表中各option的Value会有“人数值”，也有“部门名称”。这样，本页的人数框能通过一定的字符串处理，获得这个Value中关于人数的数值。而Post到下一个验证页面的时候，可以通过PHP的字符串处理，获得部门的值。如上，应该说明的清楚了吧？拜托哪位高手能指点一二呀。

看看你要的是不是这样的效果.
提交的时候做个处理,把部门和人数用"&"来拼接上了.也可以用别的,自己随便了.
//搞笑但简单的办法：到下个页面中有字符串处理下deb_in_line_slt提交过来的值
