Call C++ from Java script

Hi Everyone,

I want to call some library fuctions written in C++ from web application i. e. java script,

Which one is best way in Tizen?

and How this c++ to java script mapping is done in Tizen Architecture?

In android they used JNI, with Tizen also any such kind of layer is available?

Any body is having information of idea please share.

Thanks in advance.

 

Thanks

Dinesh

Hi, In Tizen SDK you can find a class "Tizen::Web::Controls::IJavascriptBridge" where you can call javascript.For more you can refer to the link https://developer.tizen.org/help/topic/org.tizen.native.apireference/classTizen_1_1Web_1_1Controls_1_1IJavaScriptBridge.html

Hi John, Thanks for your response, This seems it will call JavaScript code from Native App, correct me if I am getting it incorrect, But I want to call C++ code from Java Script (Web app to My own library written in C++). java Script -- > C++ any idea is welcome. Please suggest me. Thanks in advance.

You should have a look at NPPlugin Sample application. it is about using NPRuntime (NPAPI) https://developer.tizen.org/help/index.jsp?topic=%2Forg.tizen.web.appprogramming%2Fhtml%2Fsample_descriptions%2Fnpplugin.htm (note : I never succeeded to find the source code for the embedded native plugin, from javascript side, the object is loaded from the HTML code using the tag object with id="NPPluginMatrix" ) Cordially.
