Support for selecting files in phonegap for iOS and Android

I am creating a cross platform app using Apache Cordova for ios and android. I need "File chooser" support in my application to upload files (document files without images) to a server from a mobile device. Is there an alternative for the type = 'file' input element that also supports older versions?

Note. The location of the file to be uploaded to the server is unknown. The user needs to view the phone and download the documents
