Bholley,
Thanks for your quick response. Sorry for being naive and I am a newbee in this
area. After modifying the IDL and jsXPCOM as below, my question now is "How to
call the injected or page java scripts by using nsIDOMWindow"?
1 - My modified IDL
#include "nsISupports.idl"
[scriptable, uuid(f22e7808-17a7-11e4-9620-58fc1d5d46b0)]
interface nsIJSSupport: nsISupports
{
boolean doSomething(in nsIDOMWindow gdomwindow, in string
siteId,in bool bRescanPage, in bool bIsFF30orGreater);
};
2 - My modified JS file is as follows
Components.utils.import("resource://gre/modules/XPCOMUtils.jsm");
function MyComponent() { }
MyComponent.prototype = {
classDescription: "Shans Javascript XPCOM Component",
classID:
Components.ID("{17ca79ee-17ae-11e4-a5ea-fa011e5d46b0}"),
contractID: "@Shans.com/jssource;1",
QueryInterface:
XPCOMUtils.generateQI([Components.interfaces.nsIJSSupport,Components.interfaces.nsISupports]),
doSomething: function(gdomwindow, siteId, bPage, bIsGreater) {
//win.wrappedJSObject.injectedJSFunctioninWebPage(gdomwindow, siteId, bPage,
bIsGreater);
//How to call the injected or page java scripts by using nsIDOMWindow??
}
}
Thanks for pointing me in right direction.
