How to start and stop/pause setInterval?

Question

I\'m trying to pause and then play a setInterval loop.

After I have stopped the loop, the \"start\" button in my attempt doesn\'t seem to work :

Answer 1

(function(){
    var i = 0;
    function stop(){
        clearTimeout(i);
    }

    function start(){
        i = setTimeout( timed, 1000 );
    }

    function timed(){
       document.getElementById("input").value++;
       start();
    }

    window.stop = stop;
    window.start = start;
})()
