JS参数传递

现用Smarty做网站,想把在html页面中JS计算出来的变量fee提交到一个php处理页面去,用语句

document.frm.action="?do=info&action=submit&id=<!--{$meminfo1.member_id}-->&fee=fee";

在php中获取:

$fee=empty($_GET[&#39;fee&#39;])?&#39;&#39;:trim($_GET[&#39;fee&#39;]);

不过就是传递不过来,请问各位大虾正解如何?(JS中代码如下)

------解决方案--------------------
确实对新手来讲由于缺少必要的条理逻辑,所以只能用简单的传值方式来实现页面间值得传递,由于我也是新手了所以也只能说说我的困惑,我用js获取本页的文本结点然后通过异步请求将值传递到后台页面,然后打开后台php页面发现传递过来的值不可以直接运用,就是本身后台页面就是用来显示的,显示的东西和传递过来的值密切相关。怎么才能将上个页面传递过来的值直接用于显示呢? 
------解决方案--------------------
你的代码还是用代码格式贴出来吧,这样看的很不舒服捏! 
------解决方案--------------------
你最好打开编译后的文件,看看

document.frm.action="?do=info&action=submit&id=<!--{$meminfo1.member_id}-->&fee=fee";


变成了什么 
------解决方案--------------------

document.frm.action="?do=info&action=submit&id=<!--{$meminfo1.member_id}-->&fee="+fee;
