JS compilation of xpcom implementation

For a long time ago, share the document. However, gecko2.0 is now available, so some details may change. Currently, gecko2.0 has not been studied. To be continued.

Objective: To understand the idea of JS implementing XPCOM.

The JS-implemented XPCOM and xpt must be placed in a folder, that is, the components folder.
(Similarly, the C ++-implemented XPCOM (DLL file) must be placed in the same folder as xpt, which is also under the components folder ).

Document URL:

Http://developer.mozilla.org/en/How_to_Build_an_XPCOM_Component_in_Javascript

Compile command settings:
{Sdk_dir}/bin/xpidl-M typelib-w-v-I {sdk_dir}/IDL-e helloworld. xpt helloworld. IDL

Example of compiling command:
D:/sourcecode/xulrunner-SDK/xulrunner-sdk-1.9/SeaMonkey-xulrunner-SDK/bin/xpidl
-M typelib-w-v-I
D:/sourcecode/xulrunner-SDK/xulrunner-sdk-1.9/SeaMonkey-xulrunner-SDK/IDL
-E
D:/log/imservice. xpt

D:/imservice. IDL

 

Problems encountered during compilation:
1. coding problem: xp idl does not recognize UTF-8. A little dizzy.
2. The path cannot contain spaces.

Add instances with multiple interfaces to a component:

IMService. idl

# Include "nsISupports. idl"
[Scriptable, uuid (EED9537B-E056-4f0d-834A-6AEDF8E5B14A)]
Interface ceopIIMService: nsISupports {
};

[Scriptable, uuid (3CBED3C4-A0D8-11DD-AF3E-E43F56D89593)]
Interface ceopIIMAccountService: nsISupports {
};

IMService. js

Components. utils. import ("resource: // gre/modules/XPCOMUtils. jsm ");
// Utils
Const Cc = Components. classes;
Const Ci = Components. interfaces;

/*************************************** ********************
Class definition
**************************************** *******************/

// Class constructor
Function IMService (){}

// Class definition
IMService. prototype = {
// Properties required for XPCOM registration:
Classdescription: "ce imservice ",
Classid: components. ID ("{AD3F34D6-9688-11DD-B0C5-F7CC56D89593 }"),
Contractid: "@ c.cn/imservice1_1 ",

QueryInterface: xpcomutils. generateqi ([CI. ceopiimservice, CI. ceopiimaccountservice
]),

.....
};

VaR components = [imservice];

Function nsgetmodule (compmgr, filespec ){
Return xpcomutils. generatemodule (components );
}

(Haha, a component that contains multiple interfaces is complete .)
