How can I call a plugin in phonegap from a server page for iOS?

I have a html page in a server, and load it with phoneGap for iPhone. In my html page, I call a native plugin but dont work. The same html page in local project, work well. I also have the JS plugin file in the server.

Capture image when scanning bar code

I'm using BarcodeScanner from phonegap-plugins, it is working fine, but i want to capture the image when it completes scanning and gives success result. I want that captured image which i'll show that this barcode is scanned.

Android phonegap app : unable to retrieve an image taken by the camera using my own code (not phonegap"s)

Note- even though im using phonegap, the question is not about some issue in that.
