mcbraz...@gmail.com   프로필 보기 Hello, I've written a scriptable firefox plugin that is able to receive messages from JavaScript.  I now need to send messages from the plugin to JS.  The only way I've found to do this is through the use of the nsIObserverService using the following code:     nsCOMPtr<nsIServiceManager> servMan;     nsresult rv = NS_GetServiceManager(getter_AddRefs(servMan));     nsCOMPtr<nsIObserverService> observerService;     rv = servMan->GetServiceByContractID("@mozilla.org/observer- service;1", NS_GET_IID(nsIObserverService), getter_AddRefs(observerService));     observerService->NotifyObservers(NULL, "Topic", 0); On the JS side, I will declare an observer that listens for "Topic". First of all, is this the recommended way to communicate from the plugin to JS? Second, when I linked my plugin with xpcom.lib, it no longer gets instantiated by firefox (I just get a blank window).  I checked the dependencies on my plugin dll and they are all satisfied. Any suggestions would be greatly appreciated. Thanks!  추가 옵션 2007년9월1일, 오전6시12분 뉴스그룹: netscape.public.mozilla.xpcom 보낸 사람: mcbraz...@gmail.com 날짜: Fri, 31 Aug 2007 14:12:39 -0700 지역: 2007년9월1일(토) 오전6시12분 제목: Calling JavaScript from C++ plugin 작성자에게 회신 | 전달 | 인쇄 | 개별 메시지 | 원문 보기 | 이 메시지 신고 | 이 작성자의 메시지 찾기 Hello, I've written a scriptable firefox plugin that is able to receive messages from JavaScript.  I now need to send messages from the plugin to JS.  The only way I've found to do this is through the use of the nsIObserverService using the following code:     nsCOMPtr<nsIServiceManager> servMan;     nsresult rv = NS_GetServiceManager(getter_AddRefs(servMan));     nsCOMPtr<nsIObserverService> observerService;     rv = servMan->GetServiceByContractID("@mozilla.org/observer- service;1", NS_GET_IID(nsIObserverService), getter_AddRefs(observerService));     observerService->NotifyObservers(NULL, "Topic", 0); On the JS side, I will declare an observer that listens for "Topic".

You can use methods such as JS_CallFunctionName to call java script from C/C++ if this is what you are looking for. You basically get a hold of the JS Context and JS Object and then pass in the name of the function you want to call + the arguments that you want to pass into this function.
