Paypal transaction inside a modal?

Is there a way to show the Paypal transaction window within a modal window? For example, we currently have users clicking on the "Pay Now" button, and I can either get it to display in a new window/tab so they can do their transact开发者_如何学Cion, or I am able to have it display in a popup. However, I tried to push the Paypal data into either a div or iframe within a modal and can't seem to get it to work--it forces a reload of the page and goes to Paypal instead. I want the page to remain static, and not forward the user to Paypal--instead, I want that Paypal window to show in a modal. Is this even possible? I'm thinking not, but thought I'd try asking...

nope, it's a security issue, paypal wants to maintain control so their users can be sure they are dealing with them directly
