will help you Assuming your server will return a Json which will represent your ticket.
Your jQuery post would look something like this:
code :
var ticketValueFromServer;

jQuery.post(
  dataType : "JSON",
  data : {"username" : username, "ipaddress" : ipaddress},
  url: myserverlocation,
  success: function(response){
    ticketValueFromServer = response.ticket;
  }
);
How do I autofill textbox values from mysql query result onChange of dropdown?

wish helps you A few things since my original post...mysql_ is no longer safe. Also it's not good to have everything in one file, best to separate the sql & business logic from your view, lookup MVC pattern. However, here is the quick & dirty method: you can see end result here: http://jsfiddle.net/webaholik/kcce6Ls9/
code :
<?php
$sql = "SELECT id, 
    customer_name AS name, 
    customer_phone AS phone, 
    customer_address AS address, 
    customer_city AS city, 
    customer_state AS state, 
    customer_zip AS zip, 
    customer_notes AS notes 
    FROM table";
$schoolInfo = $pdo->query($sql)->fetchAll(PDO::FETCH_ASSOC);

$array = array();
foreach ($schoolInfo as $item) {
    $array[$item['id']] = $item;
}
$json = 'var SchoolInfo = ' . json_encode($array) . ';';
?>
<form action="" method="post" name="booking_form" class="booking"
style="width: auto">
<select id="customer_name" name="customer_name">
    <option value="index.php">Click to select your school</option>
<?php foreach($schoolInfo as $row){?>
    <option value="<?php echo $row['id']; ?>"><?php echo $row['name'].", ".$row['city']; ?></option>
<?php } ?>
</select>
<input type="text" name="customer_address">
<input type="text" name="customer_city">
<input type="text" name="customer_state">
<input type="text" name="customer_zip">
</form>
<script>
<?php echo $json;?>

$("#customer_name").change(function(){
    var sid = $(this).val();
    $("input[name='customer_address']").val(SchoolInfo[sid].address);
    $("input[name='customer_city']").val(SchoolInfo[sid].city);
    $("input[name='customer_zip']").val(SchoolInfo[sid].zip);
});
</script>

fixed the issue. Will look into that further I'm a High School student who takes a programming course (JavaScript) at school. We just had a test (which I miserably failed), but we are allowed to try again. , Below code will work for you:
code :
var resultatListe = [];
function funcSjekkBoks(checkboxEl) {
    var value = parseInt(checkboxEl.value);
    if (checkboxEl.checked) {
        resultatListe.push(value);
        console.log(resultatListe);
    }
    else {
        console.log("usant");
        var indexToRemove = resultatListe.indexOf(value);
        resultatListe.splice(indexToRemove,1);
    }
}
