今天发现了一个很有意思的事情，就是打开子窗口时改变了 __hash__ 值，因为子窗口当中有表单
//+---------------------------------------------------
//| 打开模式窗口，返回新窗口的操作值
//+---------------------------------------------------
function PopModalWindow(url,width,height)
{
var result=window.showModalDialog(url,"win","dialogWidth:"+width+"px;dialogHeight:"+height+"px;center:yes;status:no;scroll:no;dialogHide:no;resizable:no;help:no;edge:sunken;");
return result;
}
表单代码如下

红色部分是我的解决方案 ，为了不改变 session 值，子窗口中的表单，不能让它自动生成 __hash__ 令牌验证的 session
