web.animation.KeyframeEffect — clojure-interop/cljs-web-api 1.0.2

The KeyframeEffect interface of the Web Animations API lets us sets of animatable properties and values, called keyframes. These then be played using the Animation() constructor.

composite cljs

(composite this)

Property.

The composite property of a web.animation.KeyframeEffect resolves an element's animation impacts its underlying property values.

`// getting var compositeEnumeration = keyframeEffect.composite;

// setting keyframeEffect.composite = 'accumulate';`

constructor cljs

Constructor.

The KeyframeEffect() constructor of the Web Animations API returns a new web.animation.KeyframeEffect object instance, and also allows you to clone an existing keyframe effect object instance.

The first type of constructor (see above) creates a completely new web.animation.KeyframeEffect object instance. Its parameters are:

element The DOM element to be animated, or null. keyframeSet An keyframe object or null. keyframeOptions Optional

Either an integer representing the animation's duration (in milliseconds), or an js.Object containing one or more of the following:

delay Optional The number of milliseconds to delay the start of the animation. Defaults to 0. direction Optional Whether the animation runs forwards (normal), backwards (reverse), switches direction after each iteration (alternate), or runs backwards and switches direction after each iteration (alternate-reverse). Defaults to "normal". duration Optional The number of milliseconds each iteration of the animation takes to complete. Defaults to 0. Although this is technically optional, keep in mind that your animation will not run if this value is 0. easing Optional The rate of the animation's change over time. Accepts the pre-defined values "linear", "ease", "ease-in", "ease-out", and "ease-in-out", or a custom "cubic-bezier" value like "cubic-bezier(0.42, 0, 0.58, 1)". Defaults to "linear". endDelay Optional The number of milliseconds to delay after the end of an animation. This is primarily of use when sequencing animations based on the end time of another animation. Defaults to 0. fill Optional Dictates whether the animation's effects should be reflected by the element(s) prior to playing ("backwards"), retained after the animation has completed playing ("forwards"), or both. Defaults to "none". iterationStart Optional Describes at what point in the iteration the animation should start. 0.5 would indicate starting halfway through the first iteration for example, and with this value set, an animation with 2 iterations would end halfway through a third iteration. Defaults to 0.0. iterations Optional The number of times the animation should repeat. Defaults to 1, and can also take a value of js.Infinity to make it repeat for as long as the element exists.

composite Determines how values are combined between this animation and the element's underlying values. iterationComposite Determines how values build from iteration to iteration in the current animation.

The second type of constructor (see above) creates a clone of an existing web.animation.KeyframeEffect object instance. Its parameter is as follows:

sourceKeyFrames A web.animation.KeyframeEffect object that you want to clone.

get-computed-timing cljs

(get-computed-timing this)

Method.

The getComputedTiming() method of the web.animation.AnimationEffect returns the calculated timing properties for this animation effect.

var currentTimeValues = animation.getComputedTiming();

get-keyframes cljs

(get-keyframes this)

Method.

The getKeyframes() method of a web.animation.KeyframeEffect an Array of the computed keyframes that make up this animation with their computed offsets.

var keyframes = keyframeEffect.getKeyframes();

iteration-composite cljs

(iteration-composite this)

Property.

The iterationComposite property of a web.animation.KeyframeEffect how the the animation's property value changes accumulate or each other upon each of the animation's iterations.

`// getting var iterationCompositeEnumeration = keyframeEffect.iterationComposite;

// setting keyframeEffect.iterationComposite = 'replace';`

set-composite! cljs

(set-composite! this val)

Property.

The composite property of a web.animation.KeyframeEffect resolves an element's animation impacts its underlying property values.

`// getting var compositeEnumeration = keyframeEffect.composite;

// setting keyframeEffect.composite = 'accumulate';`

See also: https://developer.mozilla.org/en-US/docs/Web/API/KeyframeEffect/composite

set-iteration-composite! cljs

(set-iteration-composite! this val)

Property.

The iterationComposite property of a web.animation.KeyframeEffect how the the animation's property value changes accumulate or each other upon each of the animation's iterations.

`// getting var iterationCompositeEnumeration = keyframeEffect.iterationComposite;

// setting keyframeEffect.iterationComposite = 'replace';`

See also: https://developer.mozilla.org/en-US/docs/Web/API/KeyframeEffect/iterationComposite

set-keyframes cljs

(set-keyframes this keyframes)

Method.

The setKeyframes() method of the web.animation.KeyframeEffect replaces the keyframes that make up the affected KeyframeEffect a new set of keyframes.

existingKeyframeEffect.setKeyframes(keyframes);

set-target! cljs

(set-target! this val)

Property.

The target property of a web.animation.KeyframeEffect interface the element or pseudo-element being animated. It may be null animations that do not target a specific element. It performs both a getter and a setter, except with animations and transitions by CSS.

`var targetElement = document.getElementById("elementToAnimate");

var keyframes = new KeyframeEffect( targetElement, keyframeBlock, timingOptions );

// returns #elementToAnimate keyframes.target;

// assigns keyframes a new target keyframes.target = newTargetElement;`

target cljs

(target this)

Property.

The target property of a web.animation.KeyframeEffect interface the element or pseudo-element being animated. It may be null animations that do not target a specific element. It performs both a getter and a setter, except with animations and transitions by CSS.

`var targetElement = document.getElementById("elementToAnimate");

var keyframes = new KeyframeEffect( targetElement, keyframeBlock, timingOptions );

// returns #elementToAnimate keyframes.target;

// assigns keyframes a new target keyframes.target = newTargetElement;`
