Returning to Flex after PayPal Express Checkout payment

Question

I have successfully integrated PayPal Express into a Flex application. In DoExpressCheckoutPayment.php, I have the following JavaScript line of code that will not execute:

window.opener.window.document.getElementById('index').paymentComplete();

'index' - http://mysite.com/index.html# contains index.swf 'paymentComplete()' - the function that finishes processing the transaction

Has anyone successfully activated callback methods back from a popup to a Flex application using JavaScript?

Thank you in advance for any help,

Orville

Answer 1

SWFAddress将是一个非常好的解决方案。

Answer 2

In Flex, the address in URLRequest was absolute ( http://mysite.com/phpfolder/ ) and not relative (/phpfolder) to the SWF. For some reason JavaScript requires the relative URL for the following line to work. I am not sure why.

window.opener.window.document.getElementById('index').paymentComplete();

Answer 3

如果您可以在包含flex应用程序的html页面中使弹出窗口调用JS方法，则可以使用ExternalInterface类的addCallBack方法使该JS方法与flex应用程序通信。

Answer 4

对于getElementById，请使用OBJECT标签中的EMBED标签中的ID。而不是OBJECT标签本身中的ID！
