Question

I am trying to get keys from users using Javascript and storing it in a Javascript object.

i.e. when I press A, 1 should be added to myJSON[65].
The following code works perfectly but if users press a key for a long time it will detect it as multiple key presses. I don’t wan’t that. Is there a better way to do this?

var myJSON={65:[],83:[],68:[],70:[],71:[]};
window.onkeydown=function(e){
    console.log(myJSON);
    myJSON[parseInt(e.keyCode)].push(1);
}

Try this:

var keyStopper = false;

window.onkeydown = function(e) {
    if (keyStopper) {
        return e.keyCode;
    }
    keyStopper = true;
    console.log(myJSON);
    myJSON[parseInt(e.keyCode)].push(1);
};

window.onkeyup = function(e) {
    keyStopper = false;
};
