父窗体与子窗体之间的调用-使用模态窗体之间传递多个值

在web应用中，如何以模态窗口方式新打开子窗口，并往子窗口里传递多个值，而在子窗口中，能接受这些值，并且对这些值修改后，可以再提交传递给父窗口呢？在codeproject上，有篇文章介绍了方法，下面介绍如下：
1 先建一个叫Parent.html的父窗口，写入其中的HTML代码如下：

<HTML>
<HEAD>
<title>Parent Webform</title>
      <script language="javascript">
function OpenChild()
{
var ParmA = retvalA.value;
var ParmB = retvalB.value;
var ParmC = retvalC.value;
var MyArgs = new Array(ParmA, ParmB, ParmC);
var WinSettings = "center:yes;resizable:no;dialogHeight:300px"
var MyArgs = window.showModalDialog(
"Child.html", MyArgs, WinSettings);
if (MyArgs == null)
{
window.alert(
      "Nothing returned from child. No changes made to input boxes")
}
else
{
retvalA.value=MyArgs[0].toString();
retvalB.value=MyArgs[1].toString();
retvalC.value=MyArgs[2].toString();
}
}
</script>
</HEAD>
<body>
<P><INPUT id="retvalA" type="text" value="ValueA"></P>
<P><INPUT id="retvalB" type="text" value="ValueB"></P>
<P><INPUT id="retvalC" type="text" value="ValueC"></P>
<P><BUTTON  type="button">
Open Child Window</BUTTON>
</P>
</body>
</HTML>2 建立一个叫Child.html的窗体，写入HTML代码如下

<HTML>
<HEAD>
<TITLE>Child Webform</TITLE>
<script language="javascript">
function Done() {
var ParmA = tbParamA.value;
var ParmB = tbParamB.value;
var ParmC = tbParamC.value;
var MyArgs = new Array(ParmA, ParmB, ParmC);
window.returnValue = MyArgs;
window.close();
}
function doInit() {
var MyArgs = window.dialogArguments;
tbParamA.value = MyArgs[0].toString();
tbParamB.value = MyArgs[1].toString();
tbParamC.value = MyArgs[2].toString();
}
</script>
</HEAD>
<BODY >
<P>Param A:<INPUT id="tbParamA" TYPE="text"></P>
<P>Param B:<INPUT ID="tbParamB" TYPE="text"></P>
<P>Param C:<INPUT ID="tbParamC" TYPE="text"></P>
<BUTTON  type="button">OK</BUTTON>
</BODY>
</HTML>
