opener.formId.textId = str;//hidden控件Id
  self.close();一系列计算在父窗口做，先取hidden控件得值，在计算
那如何在同一个窗口内获得本窗口控件的value呢？
我只会提交表单，在下一个页面中获得控件值，呵呵
偶是新手啊~~~
document.getElementById("ID").value
document.getElementsByName("name").value
document.getElementsByName("name")[0].value
在父窗口的页面里这么写？
<%
  String strTest = document.getElementsByName("name").value;
%>
就可以得到了吗？
父窗口是要写javascript，而不是服务器端语言
可以写
<script language=javascript>
    var strTest = document.getElementById("ID").value
    alert(strTest);
</script>
父窗口

七太保大侠：你在子窗口里returnValue了一个字符串，在父窗口里是用什么方法得到的？我没看出来，呵呵，比较菜
天外水火大侠：我是要在服务器端得到，这样alert出来对我要实现的功能来说没有用啊：（
在服务器端得到，恐怕你还要提交个表单到一个隐藏的iframe里去，或是用AJAX吧
