Introduction

  • What is SCAP?
    SCAP(Signage Common Application Platform) is a JavaScript library that enables the use of services provided by webOS based LG Commercial Display Platform.
    This library can be used in a web-application in the same way as other JavaScript-based libraries(e.g. jQuery).

    What is Cordova?
    Cordova is a JavaScript library that enables the use of hardware features such as the camera or accelerometer in a web application. It is used to make a web application that works on a mobile operating system with UI frameworks such as jQuery Mobile, Dojo Mobile, Sencha Touch and Enyo.

    Cordova has the following features:
    - Can develop applications without having to use the native language provided by the mobile operating system
    - Can be distributed to a number of platforms using a single web programming code
    - Can implement common mobile operating system features using an API
    For more information about Cordova, see http://cordova.apache.org.
