如何提交联动菜单的值

我用document.getElementById(reobj).outerHTML="<select id='member' style='width:100px'>"+option+ "</select>";生成的联动菜单，但是看源码里没有option选项，如何把值取到并提交到PHP页面里去处理呢？？谢谢，在线等

document.getElementById(reobj).outerHTML
这个在源文件里面是看不到，js这样赋值是在内在里面的。界面上是可以显示的还有，
你想怎样提交给php页面呢?
是选择select时提交给php?
document.getElementById(reobj).outerHTML="<select id='member' name='member'style='width:100px'>"+option+ "</select>"
加个name，然后和取text一样处理，就能取到选中的直
如果要option的所有值，要用js把option的所有值做成字符传，夫给hidden，再取hidden
回复一个小泡：生成的是单选菜单，我想选个值后可以POST给main.php
我再试下楼上说的方法，谢谢
“如果要option的所有值，要用js把option的所有值做成字符传，夫给hidden，再取hidden”如何用JS把所有值做成字符串呢？单选的搞定了，现在就差下面的多选了，也是用outerHtml生成的，不过是多选的，谢谢，用数组取不到
多选点击的时候不能够,触发事件,给hidden这个方法应该可以

function cc(){
var a=document.getElementsByName("sel")[0].options
var c=""
for(var i=0;i<a.length;i++){
  c=c+a[i].value+","
}
alert(c)
document.getElementsByName("bbb")[0].value=c
}

</body>
</html>下个页面取bbb的、值，和text一样，然后分割数组
我把我的代码发上来给你们看一下吧，有点说不明白，我从一个部门列表选择后（单选）传给PHP生成部门成员再传回来用outerHtml生成列表（单选），在这同进还把所有成员生成多选列表框，然后在多选列表里把要选取的成员再传给另一个列表框（多选），现在就是要把这个列表框里的值再传给PHP处理，代码如下：包括JS，用DW打开就能看明白我说的意思了
