Pass html form data in bi-directional ways

M

Matt

I have 2 html pages, both have a text box and a button. In page1.html,
when the user enter a text in text box, and click button, it will pass
the form data to page2.html, and it will open page2.html in a smaller
window and that data will show in text box in page2.html. In
page2.html, if the user changes the text box data and click the
button, it will update the data in existing window for page1.html. In
other words, data can transfer back and forth in page1.html and
page2.html.

I already wrote the html pages as shown below. However, after clicking
the button in page1.html, the data can be shown in text box in
page2.html,
But when user changes the text box data in page2.html, it will open
another window for page1.html, not change the data in existing window
for page1.html, and data cannot shown in new window for page1.html
also.
I am just using regular button, and i am not using submit button.

any ideas? Please advise. Thanks!

-------------- page1.html ----------------------------
<html>
<head>
<script>
function openwindow()
{ var myObject = new Object();
myObject.firstName = fname.value;
alert(myObject.firstName);
var sReturn = window.showModalDialog("page2.html", myObject,
"menubar=no, titlebar=no, toolbar=no, location=no, directories=no,
status=no, menubar=no, scrollbars=yes, resizable=no, copyhistory=yes,
width=400, height=500");
}
function window_onload()
{ alert("window onload...");
if (window.dialogArugments != null)
{
alert("window.dialogArguments != null");
var oMyObject = window.dialogArguments;
fname.value = oMyObject.firstName;
}
else
{ alert("window.dialogArguments = null");
}
}
</script>
</head>
<body onload="window_onload()">
<H2>Page 1</H2>
<P>name: <input type="text" name="fname">
<P><input type="button" value="validate" onclick="openwindow()">
</body>
</html>


------------------------ page2.html --------------------------
<html>
<head>
<script>
function openwindow()
{ var myObject = new Object();
myObject.firstName = fname.value;
alert(myObject.firstName);
var sReturn = window.showModalDialog("page1.html", myObject,
"menubar=no, titlebar=no, toolbar=no, location=no, directories=no,
status=no, menubar=no, scrollbars=yes, resizable=no, copyhistory=yes,
width=400, height=500");
}
function window_onload()
{ alert("window onload...");
// if (window.dialogArugments != null)
// {
// alert("window.dialogArguments != null");
var oMyObject = window.dialogArguments;
fname.value = oMyObject.firstName;
// }
// else
// { alert("window.dialogArguments = null");
// }
}
</script>
</head>
<H2>Page 2</H2>
<body onload="window_onload()">
<P>name: <input type="text" name="fname">
<P><input type="button" value="validate" onclick="openwindow()">

You need to keep in mind two things if this is going out onto the internet
rather than an intranet. A *lot* of people have popup blockers these days,
so your popup window (via window.open()) will fail. Some people will argue
you shouldn't use JavaScript at all because people have it disabled, but
honestly very few people actually disable JS.

I would probably do much of what's below *server side* and not rely on the
client misbehaving. Post your data to a server side script instead. You can
then easily populate form entries in any window you choose.
