In the JSPong example I linked, the first thing to look at should probably be PongAI.js. Since this gives you an idea of what is being achieved. Then read the ReadMe.txt to get an overview of the different classes involved. You could then have a look at JSShape.m is where the "ball" class is constructed and it's properties are associated with Objective C implementation (by adding static values to the class definition). There is one oddity though, I do not understand why NSObject is inherited from, since I thought use of the JavaScriptCore API meant that developers didn't have to inherit from classes in this manner...that the API did this for them. Maybe someone on this mailing list can help clarify this? > --- 09年7月4日，周六, Jack Wootton <[email protected]> 写道： > > 发件人: Jack Wootton [email protected] > 主题: Re: [webkit-dev] how to extend the javascript native object? > 收件人: "胡 波" <[email protected]> > 抄送: [email protected] > 日期: 2009年7月4日,周六,上午12:26 > > To add, it maybe useful to look at the following files in the > JavaScriptCore (Although, personally I didn't find them particularly > easy to understand.) > > JavaScriptCore\API\testapi.c > testapi.js > > > There are also some example programs that do what you want to do, only > with different objects. > > JSPong: http://developer.apple.com/SampleCode/JSPong/index.html > > JSInterpreter: > http://developer.apple.com/samplecode/JSInterpreter/index.html > > More programs can be found here: > > http://developer.apple.com/SampleCode/Cocoa/idxInternetWeb-date.html > > > > 2009/7/3 Jack Wootton <[email protected]>: >> Are you saying you wan to add a 'widget' property to the Window >> object?
