The first thing you need to do is take a look at the Ajax documentation:https://api.jquery.com/jQuery.ajax/

Ajax is for sending requests but it is possible to get something to run on the success:

Here is a basic Ajax call:

$.ajax({
    url: "ajax_content.php",
    type: "POST",
    data: ({
        page: page,
        content: content
    }),
    success: function (data) {  alert (data) }
 });

As you can see the function in success passes back 'data'. so, lets say you wanted to pass back some information you had got from a database. you would need to make sure that the output is json_encode($data); in the ajax_content.php page. That would then give you something. You can then use alert() to see the data. Make sense?

page:page and content:content are declared variables that allow you pass info to the file. Like if you needed to pass a password or id etc.. — MarkP, Apr 28 '14 at 09:20

By ajax you can only send request. You may send it to the page that calls your function as you need

what you need to is create a php file write your code and simply call that php file via ajax

 $.ajax({
        type: 'POST',
        url:"example.php",
        dataType:'json',
        success: function () { }
});

Check this other answer: jQuery Ajax POST example with PHP

as lampdev wrote above, you'll just need to adapt the basic aJax call to your code

 $.ajax({
        type: 'POST',
        url:"code.php",
        dataType:'json',
        success: function () { }
});

You'll need 3 files, supposing you've js in a different file as the form. It will be something like:

form.php/html
script.js
code.php
