How to unregister events in electron?
I am making an application using atom-shell that needs to load several html pages. Each time I load a different page, I need to execute some custom script. For this I am using mainWindow.webContents.on('did-finish-load', ...). But since I need to have a custom function for each file, I would like to unregister from the did-finish-load event.
Example:
mainWindow.webContents.on('did-finish-load',function()
console.log('loaded page1');
mainWindow.webContents.unregister('did-finish-load') // <= does that exist?
);
mainWindow.loadUrl('file://.../page1.html');
electron

BrowserWindow extends EventEmitter, so you would remove a listener the same way you typically would in Node.js:
var handler = function ()
// ...
;
mainWindow.webContents.on('did-finish-load', handler);
// Later:
mainWindow.webContents.removeListener('did-finish-load', handler);

Hi, i m new to electron, if it is the same EventEmitter as nodejs, once method can handle that easily. nodejs.org/api/events.html#events_emitter_once_event_listener, is it ?

That's a good point, and yes, that should work too. I suppose I answered the question perhaps a little too directly as it related to unregistering a listener.
