How to trace or debug all available javascript events

This is my favorite reference, it is updated more frequently than some of the other posts: https://developer.mozilla.org/en-US/docs/Mozilla_event_reference?redirectlocale=en-US&redirectslug=DOM%2FDOM_event_reference

Here is a list of Javascript events: https://developer.mozilla.org/en-US/docs/Web/Events

Here's a simple script to log all available events in the browser's console:

var ev = '',
    out = [];
for (ev in window) {
    if (/^on/.test(ev)) { 
        out[out.length] = ev;
    }
}
console.log(out.join(', '));

Of course you'll get only the events of the browser you're currently using.
