Impossible to use JS on Paypal Checkout Page

Hi there,

I am trying to use some custom code in order to activate a JS function on the paypal checkout page

When I added this code into my body :

The alert never appears when I load the page
(I charged Jquery in my header before)

It looks like the DOMContent is lever loaded
I also noticed that when I get into the paypal checkout page the url stays on the previous page

Thanks for helping :slight_smile:
