simple javascript loop click button

Question

I am a beginner in javascript and I want to do a loop where it clicks a button, then when another button appears on the page, the loop stops and clicks the button that appeared. (After clicking a random number of times the "loop" button, you can click the "appeared" button) Thanks so much for your help

Button to loop: document.getElementById('loop').click();

Button button that appeared: document.getElementById('appeared').click();

Answer 1

If the "appeared" element is undefined, then the clicked element will be "loop", otherwise it will be "appeared". I added a delay of 100 ms otherwise the browser may crash.

(function loop() {
  setTimeout(function() {
    const appeared = document.getElementById('appeared')
    document.getElementById(appeared?'appeared':'loop').click()
    loop()
  }, 100)
})()
