JS setTimeout() alternative

Question

Like i explain here , i can\'t use window.setTimeout() anymore and any window classical functions like clearInterval etc ...); but i need calling a JS block code as an async one

Answer 1

What about something like this?

var delay = 10000; // milliseconds
var before = Date.now());

while (Date.now() < before + delay) {};

alert('The delay has passed!');

Also, you might be interested in the Promise objects. Which could give you somtehing like this :

var customDelay = new Promise(function(resolve) {
  var delay = 10000; // milliseconds
  var before = Date.now();
  while (Date.now() < before + delay) {};
  resolve('Success!');
});

customDelay.then(function(msg) {
  document.getElementById("messageTimer").innerHTML = "Happy New Year !';
});

---EDIT--- The Promise object is part of ECMAScript 6 so there will be backward compatibility issues.

Luckily for you, jQuery does have it's own implementation of Promises! Introduction to jQuery Promises

See this page for documentation. Implementation will be similar.
