I've been working on a paypal checkout and am having difficulties, my company is offering services that can be purchased one time, or on a recurring basis, and I have the checkout page designed and using dropdowns they can choose the level of service and the frequency, well I now noticed while implementing paypal, I have to use "intent=subscription" to do subscription's, but if I have that then a normal order can't be placed, and if I have both scripts included then i get a 500 error during checkout. Is there anyway i can unload/reload the scripts that i need when the buttons change, this is what i have to change the buttons
$(".product-info :input").change(function () {
if($( ".productselect" ).val() == "basic"){
$( "#basic" ).show();
$( "#plus" ).hide();
$( "#premier" ).hide();
}else if ($( ".productselect" ).val() == "plus"){
$( "#basic" ).hide();
$( "#plus" ).show();
$( "#premier" ).hide();
}else if ($( ".productselect" ).val() == "premier"){
$( "#basic" ).hide();
$( "#plus" ).hide();
$( "#premier" ).show();
}
if($( ".timingselect" ).val() == "Single"){
paypalsingle();
$(".totamount").html("$" + $(".productselect").find(':selected').data('cost'));
}else if ($( ".timingselect" ).val() == "Bi"){
paypalmulti($(".productselect").find(':selected').data('ppbi'));
$(".totamount").html("$" + $(".productselect").find(':selected').data('costbi'));
}else if ($( ".timingselect" ).val() == "Week"){
paypalmulti($(".productselect").find(':selected').data('ppweek'));
$(".totamount").html("$" + $(".productselect").find(':selected').data('costweek'));
}
});

You can use a helper function such as the following to load/reload the SDK dynamically:
function loadAsync(url, callback) {
var s = document.createElement('script');
s.setAttribute('src', url); s.onload = callback;
document.head.insertBefore(s, document.head.firstElementChild);
}
// Usage Example:
loadAsync('https://www.paypal.com/sdk/js?client-id=test¤cy=USD', function() {
paypal.Buttons({
// Set up the transaction
createOrder: function(data, actions) {
return actions.order.create({
purchase_units: [{
amount: {
value: '0.01'
}
}]
});
},
// Finalize the transaction
onApprove: function(data, actions) {
return actions.order.capture().then(function(details) {
// Show a success message to the buyer
alert('Transaction completed by ' + details.payer.name.given_name);
});
}
}).render('body'); // Replace with selector of desired container to render in
});
(Your callback can of course be a named function such as your paypalsingle rather than an anonymous one as in the above usage example)
