Function starts automatically after condition fulfillment

Question

I want to execute function that will automatically run after upon condition fulfillment (that are changing dynamically in my JavaScript code). I was trying with document.body.onload method, but I doesn't work.

document.body.onload = myfunction()

function myfunction(){
    if(start==true && moves%2==0){
            alert("Function")
    }
}

actually, change `document.body.onload = myfunction()` to `document.body.onload = myfunction` — The Bomb Squad, Nov 17 '20 at 18:52
Well, the `onload` event only occurs once, when the document loads. If you want a function to run after a condition changes, call it when your condition changes. — Heretic Monkey, Nov 17 '20 at 18:53
you would have less issues by using `window.addEventListener("load", myfunction);` — Kulvar, Nov 17 '20 at 18:53

Actually it should work, you can test this light page :

<!doctype html>
<html>
<body>

<script>
    document.body.onload = myfunction();

  function myfunction(){
      if(true){
              alert("Function");
      }
  }
</script>

</body>
</html>

Your problem is probably that "start" or "moves" are not declared or instanced on load.
