I'm trying to make an array to tidy up my code so that I can add a bunch of event listeners to various buttons.

  for(var i = 0; i < buttoncount; i++){
    var targetid = document.getElementsByTagName("button")[i].id;
    var targetidfunc = targetid + "function";
    console.log(targetidfunc);
    document.getElementById(targetid).addEventListener("click", targetidfunc);
  }

The console has the correct function names however the event listener does not work, how can I fix this?

what is your function? – RizkiDPrast Nov 23 '16 at 22:28
why dont directly `target = document.getElementByTagName("button"); target[i].addEventListener('click', function(){alert("OK")})` – RizkiDPrast Nov 23 '16 at 22:29
