Recently I am confused about whether it's possible to send input/textarea data directly without being included in html <form>. I thought in web page, if we want to get information from user then send the text to authentication server, we must use <form> irrespective of in which way it's submitted.
But an anonymous reviewer of my paper claims that <html> can be bypassed by using an html5 tag "textarea" and JS AJAX post. While I did lots of experiments trying to implement his way but all failed.
I wonder if there is really some way to submit user info without using <form> tag?
Thank you
Thanks for everyone's reply.
Update: I followed "the_void"'s code and changed the url of AJAX to a ServerSocket (implemented by Java). The server was able to get the POST event, but it cannot read the "data" of AJAX. The following is the html code:
HTML
<!DOCTYPE html>
<head>
<meta charset="utf-8" />
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js">
</script>
<script type="text/javascript">
$(document).ready(function() {
$('#submit').click(function() {
// information to be sent to the server
info = $('#foo').val();
$.ajax({
type: 'POST',
url: 'http://10.0.0.3:8888',
data: ({ foo: info }),
// crossDomain: true,
// dataType: 'json'
});
return false;
});
});
</script>
</head>
<body>
<label>Text</label>
<textarea id="foo"></textarea>
<button id="submit">Submit via Ajax</button>
</body>
</html>
It seems that the socket server cannot read from AJAX (but it can read from < form > + < action >). Is there any way to fix the reading issue?
Thank you
