Update a JS array value with a global variable based on checkbox (true/false) form input
Question
I'm using a WorldPay JS function to create a payment form. This function creates a TOKEN that can be reusable or not. I need to update the 'reusable' flag based on a form input (checkbox) but I can't get the global variable (reuse) to update. I've created a function CHECKED that updates the variable but the WorldPay JS just ignores it. I think is due the window.onload status, but I don't know how to fix it. Any help would be greatly appreciated.
<?php
include('./header.php');
require_once('./init.php');
?>
<html>
<head>
<title></title>
<meta charset="UTF-8" />
<script src="https://cdn.worldpay.com/v1/worldpay.js"></script>
<script type='text/javascript'>
var reuse = false;
function Checked(){
reuse = document.getElementById('check').checked;
Worldpay.submitTemplateForm();
}
window.onload = function() {
Worldpay.useTemplateForm({
'clientKey':'ENTER CLIENT KEY',
'form':'paymentForm',
'paymentSection':'paymentSection',
'display':'inline',
'type':'card',
'reusable': reuse,
'saveButton':false,
'callback':function(obj){
if (obj && obj.token && obj.paymentMethod) {
var _el = document.createElement('input');
_el.value = obj.token;
_el.type = 'hidden';
_el.name = 'token';
document.getElementById('paymentForm').appendChild(_el);
var _name = document.createElement('input');
_name.value = obj.paymentMethod.name;
_name.type = 'hidden';
_name.name = 'customer';
document.getElementById('paymentForm').appendChild(_name);
document.getElementById('paymentForm').submit();
}
}
});
}
</script>
</head>
<body>
<form action="./test.php" id="paymentForm" method="post">
<!-- all other fields you want to collect, e.g. name and shipping address -->
<div id='paymentSection'></div>
<div>
<input type="checkbox" id='check'>
<input type="submit" value="Place Order" onclick="Checked()" />
</div>
</form>
</body>
</html>
NOTE: I've removed the client ID so the code won't run.

Have you tried to use function "checked" on window.onload like this:
window.onload = function() {
Worldpay.useTemplateForm({
//code....
)}
function Checked(){
//code....
}
