Hello,

You can read more about webAPIs here and here.

Some APIs are not supported yet on many platforms, and some APIs are only targeted at mobile platforms. Gaia is the Firefox OS User Interface, and is not included in Gecko.

Hope this helps :)

Hi,

Thanks for your reply, but here my question is How I can communicate Gecko to Gaia?

For example:

in Gaia my APP contains one API.

EX: Hello.js ----> function GetName() {

           var name = "Laxman";
          // Implementation of logic here

}

I want to call this API from Gecko Javascript/XPCOM C++. How I can invoke this API from Gecko?

You have to add a reference to the window, and then you can invoke it by using the same method that you would use to call it from a webpage.

Example Code: http://mxr.mozilla.org/mozilla-central/source/dom/browser-element/BrowserElementChildPreload.js#476
