EffectTiming.delay

This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The EffectTiming dictionary's delay property in the Web Animations API represents the number of milliseconds to delay the start of the animation.

Element.animate(), KeyframeEffectReadOnly(), and KeyframeEffect() all accept an object of timing properties including delay. The value of delay corresponds directly to EffectTiming.delay in timing objects returned by AnimationEffectReadOnly, KeyframeEffectReadOnly, and KeyframeEffect.

Syntax

var timingProperties = {
  delay: delayInMilliseconds
};

timingProperties.delay = delayInMilliseconds;

Value

A number specifying the delay, in milliseconds, from the start of the animation's play cycle to the beginning of its active interval (the time index at which actual animation begins). Defaults to 0.

Examples

In the Pool of Tears example, each tear is passed a random delay via its timing object:

// Randomizer function
var getRandomMsRange = function(min, max) {
  return Math.random() * (max - min) + min;
}

// Loop through each tear
tears.forEach(function(el) {  

  // Animate each tear
  el.animate(
    tearsFalling, 
    {
      delay: getRandomMsRange(-1000, 1000), // randomized for each tear
      duration: getRandomMsRange(2000, 6000), // randomized for each tear
      iterations: Infinity,
      easing: "cubic-bezier(0.6, 0.04, 0.98, 0.335)"
    });
});
