Menu
Lets say I have a web page with an iframe which contains a form. I want to set a value in a hidden field when the form has been submitted. How can I trigger an event in the main page when the form is submitted?
This is a simplified version of what I'm trying to do:
<!DOCTYPE html>
<html>
<head>
<title>TEST IFRAME UPLOAD</title>
<script type="text/javascript" src="http://code.jquery.com/jquery-1.7.2.min.js"></script>
<script type="text/javascript">
// Pseudo code for what I want to do
// (this of course doesn't work because target is inside iframe:
jQuery(document).ready(function() {
$("#file_upload_form").submit(function() {
$("input[name='fileuploaded']").val(1);
return true;
});
});
</script>
</head>
<body>
<form id="mainform" action="processform" method="post">
<input type="hidden" name="fileuploaded" value="">
<!-- more form fields here -->
</form>
<iframe id="upload-iframe">
<form enctype="multipart/form-data" id="file_upload_form" action="processfileupload" method="post">
Select an image to upload:<br/>
<input type="file" name="file">
<input type="submit" name="submit" class="submit" value="Upload">
</form>
</iframe>
</body>
</html>

Try this,
$('#upload-iframe').load(function() {
$(this).contents().find('#file_upload_form').submit(function() {
$("input[name='fileuploaded']").val("some value"); // updated
return true; //return false prevents submit
});
});
