父窗口参数在非子模态窗口的应用
说明：
通过window.dialogArguments就可以在子模态窗口里获得父窗口的参数。因为window是顶层对象，所以可以不用写。获得参数后，子窗口运用时就好像在父窗口里使用
<HTML>
<HEAD>
<TITLE>showModelessDialogEX.htm</TITLE>
<SCRIPT>
var sUserName="";
function fnCallDialog(){
showModelessDialog("myDialog.htm",window,"status:false;dialogWidth:300px;dialogHeight:300px");
}
function fnUpdate(){
oName.innerText = sUserName;
}
</SCRIPT>
