三次尝试将鼠标悬停

Question

I have this code:

mug.addEventListener('mouseover', function () {
    if (//I don't know what to put in here..) {
        console.log('game over');
    }
}

And I basically want it to say that when the user has hovered three times over an image the game is over.

Thanks!

It's very simple to do:

var mouseOverCount = 0;
mug.addEventListener('mouseover', function () {
    if (mouseOverCount >= 2) {
        console.log('game over');
    }
    mouseOverCount++;
});

I suggest you to read (or watch) some beginner programming tutorials, so you will understand basic concepts. You can find a lot of them in the internet.
