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)"
});
});
