addEventListener(“input”, callback) doesn't wo

问题:

I'm trying to listen to "oninput" event, but something is wrong with Opera:

document.getElementById("i1").oninput = function(){
    console.log("inputting");
};
document.getElementById("i1").addEventListener("input", function(){
    console.log("inputting");
});

The first one works, but the second one doesn't work....it this a bug of opera?

OK, I figured out this myself, addEventListener has a 3rd parameter, it can be ignored in Chrome but not other browsers.
