javascript - jQuery .submit() .ajax() have to click send button two times to get the correct response

I have a form with 5 fields that i am sending with AJAX to a PHP Script that does some simple validation and returns a string.

I have made a little jQuery script for the actual submission, and when i try to send the form i have to click the send button two times.

PHP

$contact_name = $_POST['contact_name'];
$contact_email = $_POST['contact_email'];

$contact_desc = $_POST['contact_desc'];

if ($contact_name == '' || $contact_email == '' || $contact_tel == '' || $contact_subject == '' || $contact_desc == '') {
    echo "empty";
    die();
}
echo $contact_name.'<br><br>';
echo $contact_email.'<br><br>';
echo $contact_tel.'<br><br>';
echo $contact_subject.'<br><br>';
echo $contact_desc.'<br><br>';

I cant find out why i have to click the button two times, i have tried some trial and error, read the forum for answers. I tried to serialize the form outsite the submit function, i just cant get this to behave the way i want. All help is greatly appreciated.

Oh, worth to mention. The actual response is that the fields are empty (php validation) the first time i click, but the second time it works as it should.

that's happening because you are preventing the default behavior which is to submit mostly ! – Hussein Nazzal Commented Oct 7, 2013 at 16:16
1 you are missing a few = for the form attributes (method and action) – Gabriele Petrioli Commented Oct 7, 2013 at 16:22
Hi Gaby, i have the method and action set? – Dan-Levi Tømta Commented Oct 7, 2013 at 16:29
@Dan-LeviTømtaHansen, i mean in the html that you posted .. (i do not think it has anything to do with your problem.. it was just an observation. the action"includes/contact.php" should be action="includes/contact.php" and the same with the method) – Gabriele Petrioli Commented Oct 7, 2013 at 16:33
@GabyakaG.Petrioli Thanks for pointing that out, did not see that one! :) – Dan-Levi Tømta Commented Oct 7, 2013 at 16:37

Make the ajax call using a regular input button instead of a submit button.

$("#button").click(function () { ... ajax ... }

I'm not sure if it makes a difference but have you tried putting what you want to happen afterwards in a success callback?

$(document).ready(function() {
    $('#contact_form').submit(function(e) {
        data = $('#contact_form').serialize();
        $.ajax({
            url: 'includes/contact.php',
            type: 'POST',
            data: data,
            success: function(response) {
                if (response == 'empty') {
                    $('#error_message').text('Noen av feltene er tomme.')
                } else {
                    $('.message').html(response);
                    $('#contact_form').fadeOut('400');
                    $('#info_line').fadeIn('400').text('Takk for din henvendelse');
                }; 
            }
        });     
        e.preventDefault();
    });
});

I'm guessing it's because the default action (submit the form) is processing before your $.ajax request. Try making e.preventDefault() first in your submit callback.

$(document).ready(function() {
    $('#contact_form').submit(function(e) {
        e.preventDefault();
        data = $('#contact_form').serialize();
        $.ajax({
            url: 'includes/contact.php',
            type: 'POST',
            data: data,
            success: function(response) {
                if (response == 'empty') {
                    $('#error_message').text('Noen av feltene er tomme.')
                } else {
                    $('.message').html(response);
                    $('#contact_form').fadeOut('400');
                    $('#info_line').fadeIn('400').text('Takk for din henvendelse');
                }; 
            }
        });     
    });
});
