How to execute a function every millisecond?

  • 772

Execute a function every millisecond

window.onload = function() {
  main();

  function main() {
    int = setInterval('dibujar()', 100);
  }


  function dibujar() {
    console.log('dibujando');
  }
}

The script above produces an error and I think it's because of the .onload function, I need window.onload = function() {}it because if I don't use it I get null objects from the html. If I don't use it, it works fine (I REPEAT: I need to use the function window.onload = function() {}):

main();

      function main() {
        int = setInterval('dibujar()', 100);
      }


      function dibujar() {
        console.log('dibujando');
      }

    I don't know why you use you int = setIntervalcan use window.setInterval()and do it in the following way:

    var intervalo;
window.onload = function (){
   initIntervalo();// funcion que inicia el intervalo
   
}
function initIntervalo(){
  intervalo = window.setInterval(myFunction,1);
    //Recorda que recibe como parametro los milisegundos. 
//Entonces si quieres que se ejecute cada 1 milisegundo debes idicarle 1 no 100 como pusiste.
}
 function myFunction (){
      console.log("Ejecutando");
    }
    <button onclick="window.clearInterval(intervalo)">Detener</button>

    Edited: You can easily do it with window.onload. You must remember that it is a function. Therefore you cannot write functions inside it. You can also store the interval in a variable to be able to access it later to stop it for example.
