问题

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

$(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;

});

});
