Listening To An Event From My Greasemonkey Script

I'm trying to figure out how to listen to an event emitter from my greasemonkey script, but I keep getting access violation errors (Permission denied to access object). Page The pa

Solution 1:

I managed to get it working. The solution was to export the callback function into unsafe context via exportFunction(myFunction, unsafeWindow)

The script part should look like this:

unsafeWindow.test.on('test', exportFunction(function(data){
   console.log(data);
}, unsafeWindow));

Big thanks to wOxxOm for pointing this out.
