How to get FORM values from an IFRAME ?

djdave · Oct 2, 2005

Pb with javascript.
I've a 'main.html' script containing an 'iframe.html' IFRAME.
The 'iframe.html' is containing a form.
My problem is that i'm unable to get form fields values. What's the
syntax ???

NB: the script has to be generic, because it has to work with any .html
(i may don't know form's name and iframe's name).

Thanks

=== MAIN.HTML ===

<html>
<head>
<meta name="generator" content="HTML Tidy, see www.w3.org">
<meta http-equiv="Content-Type" content="text/html; charset=Cp1252">
<title>main</title>
</head>
<body>

<iframe name="pub" width="200" height="100" src="iframe.html">
</iframe>

<script language="Javascript">

// HERE'S MY PROBLEM: IT DISPLAYS ANYTHING !!!
document.write(document.frames[0].document.forms[0].elements[0].value);

</script>

</body>
</html>

=== IFRAME.HTML ===

<html>

<head>
<meta http-equiv="Content-Type" content="text/html;
charset=iso-8859-1">
</head>
<body bgcolor="#ffffff" text="#000000" link="#0000ff" vlink="#800080"
alink="#ff0000">

<form method="POST" action="x" name="formIFrame">
<input type="text" name="name2" value="value2">
<input type="submit" value="POST2">
</form>

</body>
</html>

Ignore Danny, he seems to think that replying to nothing is the way to
post here, it's not. Please quote what you are replying to, this is
Usenet, not Email.

document.write(window.frames[0].document.forms[0].elements[0].value);

It won't be available until after the element in the form in the
document in the frame is loaded. In your sample code, it is trying to
access something that hasn't been loaded yet. Try changing it to the
onload event and alert it and see what you get.

Danny,

It works well when i've a form without iframe.

So, why it shouldn't when a form is insite a iframe ?

Furthermore, i need it works before the form is submitted.

Thanks.

Danny,

So, why it shouldn't when a form is inside a iframe ?

Furthermore, i need it works before the form is submitted.

Thanks.

Because your referencing is incorrect.

You begin by quoting what you are replying to.

Nothing wrong with not being good in English.

Show a sample URL of a sample page that you can't get to work.
