AJAX not working submitting form

Question

I got some AJAX code, but it doesn't get response from server. I tried many things but can't figure out why this is not working. I am running on a localhost setup with XAMPP . I want the echo to be seen in the span with id status.

AJAX on index.php

$(document).ready(function() {
    $("#registrationform").submit(function() {
        $.ajax({
            type: "POST",
            url: "registration.php",
            data: $("#registrationform").serialize(),
            success: function(data) {
                $("#status").html(data);
            }
        });

        alert("Ajax not running")
        });
});

Answer 1

Please try this code

$(document).ready(function() {
    $("#registrationform").submit(function(e){
    e.preventDefault();
        $.ajax({
            type: "POST",
            url: "registration.php",
            data: $("#registrationform").serialize(),
            success: function(data) {
                $("#status").html(data);
            }
        });

        alert("Ajax not running")
        });
});

Answer 2

You have to prevent the default behavior of the submit button

$("#registrationform").submit(function(ev) {
    ev.preventDefault();
    ...

Then you need to implement a proper failure handler, your current one will allways alert because that ajax is async

$.ajax({
    type: "POST",
    url: "registration.php",
    data: $("#registrationform").serialize(),
    success: function(data) {
        console.log(data); // check your console to see if request is success and what it contains
        $("#status").html(data);
    }
}).fail(function () { 
   alert("oh noes"); 
});

Answer 3

write the <input type="submit" value="Submit"/> before </form> close tag

 <form id="registrationform" action="">
    Voornaam: <input type="text" name="voornaam" /><br />
    Tussenvoegsel: <input type="text" name="tussenvoegsel" /><br />
    Achternaam: <input type="text" name="achternaam" /><br />
    Geslacht: <?php //include_once("parser/geslacht.php"); ?><br />
    Land: <?php //include_once("parser/land.php"); ?><br />
    Geboortedatum: <?php //include_once("parser/gebdatum.php"); ?><br />
    E-mail: <input type="text" name="e-mail" /><br />
    Wachtwoord: <input type="password" name="password" /><br />
    Hertype wachtwoord: <input type="password" name="password2" /><br /><br />
    De onderstaande vraag is nodig om uw wachtwoord terug te halen mocht u die vergeten zijn.<br />
    Geheime vraag: <select name="geheimevraag" id="geheimevraag">
    <option value="huisdier">Wat is de naam van jouw eerste huisdier?</option>
    <option value="moedername">Wat is de meisjesnaam van je moeder?</option>
    <option value="eerstebaas">Hoe heet je eerste baas?</option>
    <option value="eigenvraag">Eigen vraag opstellen</option>
    </select><br/>
    <span id="anders" style="display:none;">Eigen vraag: <input type="text"  name="eigen_vraag" style="width:300px;"/></span><br  />
    Antwoord: <input type="password" name="gantwoord" /><br />

   <input type="submit" value="Submit"/>
    </form>
    <span id="status"></span>

Your jquery script script:

<script>
$(document).ready(function() {
$("#registrationform").submit(function(ev){
ev.preventDefault();    
$.ajax ({
    type: "POST",
    url: "registration.php",
    data: $("#registrationform").serialize(),
    success: function(data) {
    $("#status").html(data);
   }
});

 alert("Ajax not running")
});
});

</script>

You need to prevent the default behavior of the form so that the page won't change location, and so that JS can do the AJAX request.

$("#registrationform").submit(function(e) {
    e.preventDefault(); //this one
    $.ajax({
        type: "POST",
        url: "registration.php",
        data: $("#registrationform").serialize(),
        success: function(data) {
            $("#status").html(data);
        }
    });
});
