How to make setInterval work?

Question

So here is my code and I want to add 1 to total every second`

var doughnut = 0;

    function myFunction(){



document.getElementById("total").innerHTML = " total: " + setInterval(doughnut +1, 1000) ;





}

Can you explain me how setInterval() works and where to put it?

Answer 1

setInterval accepts two arguments:

Basically each second (1000 ms) the function increments the doughnut value and writes the updated value to the HTML element with id total.

Try this:

var doughnut = 0;

setInterval(function () {
    doughnut++;
    document.getElementById("total").innerHTML = " total: " + doughnut;
}, 1000);
