This event fires when the ChargeAfter modal opens, which enables optional blocking on the merchant website such as preventing clicks or scrolling.

Code sample

function onModalOpen(){
  // here you can do something like blocking scrolling, removing loader in case you added 
  // it on the Checkout/Apply buttons when opening the ChargeAfter modal
}

// can be sent in Checkout/Apply flows

// Apply
ChargeAfter.payments.present('apply', {..., onModalOpen});

// Checkout
ChargeAfter.payments.present('checkout', {..., onModalOpen});
