Thanks for your support.

No amendment is made. I just sent the zip file by e-mail. Thanks!

When I restore the project zip file in project wizard, it returned the error "Unsupported file content. Please only upload Appery.io project file."

I am sure the zip file was generated by Appery.io platform recently.

Thanks! Finally, I found that the html code is equal to the below web link.

https://www.paypal.com/cgi-bin/webscr...

i.e. I put the web link into a click event of a button.

If I want to create a paypal button via the below html code, is it possible?

< form action="https://www.paypal.com/cgi-bin/webscr" method="post"
< input type="hidden" name="cmd" value="_s-xclick"
...
...
...
< /form

I see. Thanks!

I am going to write a program which receives the mail issued by mailgun. Here is their documentation.

http://documentation.mailgun.net/user...

In php, I can use the _$REQUEST to collect the http post generated by mailgun. I am not sure whether JS can do the same function.

I have a program in php and use the _REQUEST[ ] syntax. Can I deploy it in JavaScript?

// get sender, recipient fields
$subject = $REQUEST['subject'];
$text = $REQUEST['body-plain'];

Thanks!
