Class methods as event handlers in JavaScript?

Question

Is there a best-practice or common way in JavaScript to have class members as event handlers?

Consider the following simple example:

Answer 1

I don't know why Function.prototype.bind wasn't mentioned here yet. So I'll just leave this here ;)

ClickCounter = function(buttonId) {
    this._clickCount = 0;
    document.getElementById(buttonId).onclick = this.buttonClicked.bind(this);
}

ClickCounter.prototype = {
    buttonClicked: function() {
        this._clickCount++;
        alert('the button was clicked ' + this._clickCount + ' times');
    }
}
