1 先建一个叫ParentWebForm的父窗口，写入其中的HTML代码如下：
<!DOCTYPE HTML PUBLIC <span class="cpp-string">"-//W3C//DTD HTML 4.0 Transitional//EN"</span>>
<HTML>
<HEAD>
<title>Parent Webform</title>
<script language=<span class="cpp-string">"javascript"</span>>
<span class="cpp-keyword">function</span> OpenChild()
{
<span class="cpp-keyword">var</span> ParmA = retvalA.value;
<span class="cpp-keyword">var</span> ParmB = retvalB.value;
<span class="cpp-keyword">var</span> ParmC = retvalC.value;
<span class="cpp-keyword">var</span> MyArgs = <span class="cpp-keyword">new</span> Array(ParmA, ParmB, ParmC);
<span class="cpp-keyword">var</span> WinSettings = <span class="cpp-string">"center:yes;resizable:no;dialogHeight:300px"</span>
<span class="cpp-comment">//ALTER BELOW LINE - supply correct URL for Child Form</span>
<span class="cpp-keyword">var</span> MyArgs = window.showModalDialog(
<span class="cpp-string">"http://localhost/ModalWin/ChildWebForm.aspx"</span>, MyArgs, WinSettings);
<span class="cpp-keyword">if</span> (MyArgs == <span class="cpp-keyword">null</span>)
{
window.alert(
<span class="cpp-string">"Nothing returned from child. No changes made to input boxes"</span>)
}
<span class="cpp-keyword">else</span>
{
retvalA.value=MyArgs[<span class="cpp-literal">0</span>].toString();
retvalB.value=MyArgs[<span class="cpp-literal">1</span>].toString();
retvalC.value=MyArgs[<span class="cpp-literal">2</span>].toString();
}
}
</script>
</HEAD>
<body>
<P><INPUT id=<span class="cpp-string">"retvalA"</span> type=<span class="cpp-string">"text"</span> value=<span class="cpp-string">"AAA"</span>></P>
<P><INPUT id=<span class="cpp-string">"retvalB"</span> type=<span class="cpp-string">"text"</span> value=<span class="cpp-string">"BBB"</span>></P>
<P><INPUT id=<span class="cpp-string">"retvalC"</span> type=<span class="cpp-string">"text"</span> value=<span class="cpp-string">"CCC"</span>></P>
<P><BUTTON onclick=<span class="cpp-string">"OpenChild()"</span> type=<span class="cpp-string">"button"</span>>
Open Child Window</BUTTON>
</P>
</body>
</HTML> |
2 建立一个叫ChildWebform 的窗体，写入HTML代码如下
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<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 ParmA = "Aparm";
var ParmB = "Bparm";
var ParmC = "Cparm";
var MyArgs = new Array(ParmA, ParmB, ParmC);
MyArgs = window.dialogArguments;
tbParamA.value = MyArgs[0].toString();
tbParamB.value = MyArgs[1].toString();
tbParamC.value = MyArgs[2].toString();
}
</script>
</HEAD>
<BODY onload="doInit()">
<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 onclick="Done()" type="button">OK</BUTTON>
</BODY>
</HTML>
