Ajax Form 'POST' result as 'GET'

in Using jQuery • 6 years ago

Hello everyone, I'm learning some Jquery on a website and I was trying to understand how does it work ajax used with forms. I created this simple form which should send all the data using POST:

<!DOCTYPE html>
<html>
<head>
<title>Ajax Form</title>
<script src="http://code.jquery.com/jquery-3.0.0.js"></script>
</head>
<body>
<div class="row">
<div class="col-md-12">
<h1>Ajax Form</h1>
<form>
<label for="destinatio">Destinazione</label>
<select name="destination" id="destionation">
<option value="londra">londra</option>
<option value="parigi">parigi</option>
<option value="roma">roma</option>
</select>
<br>
<input type="number" name="day">
<br>
<input type="submit" value="book">
</form>
<div class="tour"></div>
</div>
</div>
</body>
<script type="text/javascript">
$(document).ready(function(){
$($('form').attr('action')).on('submit', function(event){
event.preventDefault();
var form = $(this);
$.ajax('/book.html', {
type: 'POST',
contentType: 'application/json',
dataType:'json',
data: form.serialize(),
success: function(result){
var msg = $('<p></p>');
//msg.append()
$('.tour').html(result);
console.log(this.data)
}
});
});
});
</script>
</html>

The Problem is that if I look inside the Chrome developer tools, inside the Network panel, when I sumbit the form I see that:

Request URL:
http://www.hartstudio.it/Es%202%20Ajax%20Form/?destination=londra&day=4
Request Method:
GET

Also on the search bar at the top when I submit something i see the url changes like the data it's sent using GET like this:

http://www.hartstudio.it/Es%202%20Ajax%20Form/?destination=londra&day=5

Does anyone know why?

$($('form').attr('action')).on('submit', function(event){

Should be

$('form').on('submit', function(event){

Hello,

the code was working fine the only problem is that I don't understand why if I specify the method (GET or POST), in both of the case the form data are sent using GET. (lokking in the chrome dev tool);

Then I have also another question. If I set the method inside the Ajax call, can I leave blank the form tag?

I mean is it necessary also to set in the form tag the method?

What's the difference if I set over there the method instead of inside the ajax call?
