You can output information to console using the following method:
- Declare global variable gConsoleService:
var gConsoleService;
- Initialize it on load:
gConsoleService = Components.classes['@mozilla.org/consoleservice;1']
.getService(Components.interfaces.nsIConsoleService);
(note, you can also use toJavaScriptConsole() function to open JavaScript console on startup)
- Define a function:
function MyApp_logMessage(aMessage) {
gConsoleService.logStringMessage('MyApp: ' + aMessage);
}
- Use it like here:
MyApp_logMessage('Initialized.');
