How to define number of cycles in animated Image with Javascript

I have this snipped made by gilly3 (special thanks). Is there any possibility to define and apply the desired number of cycles? As we can see, the code will repeat the sequences.

onload = function startAnimation() { 
    var frames = document.getElementById("animation").children;
    var frameCount = frames.length;
    var i = 0;
    setInterval(function () { 
        frames[i % frameCount].style.display = "none";
        frames[++i % frameCount].style.display = "block";
    }, 100); 
}

#animation img {
    display: none;
}
#animation img:first-child {
    display: block;
}

<div id="animation">

I have to recognise that I've received a sugestion: "setInterval returns an interval id. Store that id in a variable and, when you want to stop the animation, pass the id to clearInterval()" but it will be much appreciated a code update (I don't know how to write this in js).

Solution

You could do something like this where you clear the interval once it's run a certain number of times:

onload = function startAnimation() { 
    var frames = document.getElementById("animation").children;
    var frameCount = frames.length;
    var i = 0;
    var numberOfCycles = 10; // Set this to whatever you want
    var myInterval = setInterval(function () { 
        frames[i % frameCount].style.display = "none";
        frames[++i % frameCount].style.display = "block";
        if (i === numberOfCycles * frameCount) {
            clearInterval(myInterval);
        }
    }, 100); 
}

This requires the least code mutation, but you could also do something similar with setTimeout's.

Snippet here:

onload = function startAnimation() { 
    var frames = document.getElementById("animation").children;
    var frameCount = frames.length;
    var i = 0;
    var numberOfCycles = 3; // Set this to whatever you want
    var myInterval = setInterval(function () { 
        frames[i % frameCount].style.display = "none";
        frames[++i % frameCount].style.display = "block";
        if (i === numberOfCycles * frameCount) {
            clearInterval(myInterval);
        }
    }, 100); 
}

#animation img {
    display: none;
}
#animation img:first-child {
    display: block;
}
