$ yarn$ yarn dev when developing. This will:
src and make sure the corresponding examples on demo are updated/addedonCssAnimationEnd(elements, callback [, options = { continuous = false, oncePerElems = true, oncePerAnims = true }])Fires a callback function when CSS animation ends.
Examples:
onCssAnimationEnd(btn, callbackFunction)
onCssAnimationEnd(btns, callbackFunction, {oncePerAnims = false})
onCssAnimationEnd('.btn', callbackFunction)
onCssTransitionEnd(elements, callback [, options = { continuous = false, oncePerElems = true, oncePerAnims = true }])Fires a callback function when CSS transition ends
Examples:
onCssTransitionEnd(btn, callbackFunction)
onCssTransitionEnd(btns, callbackFunction, {oncePerElems = false})
onCssTransitionEnd('.btn', callbackFunction)
clearCssAnimationEnd(elements)Cleans all CSS animation end event listeners
clearCssTransitionEnd(elements)Cleans all CSS transition end event listeners
addClass(elements, classnames)An extended implementation of Element.classList.add(): adds classname(s) to single or multiple elements
Examples:
addClass(btn, "btn--green");
addClass(".btn", "btn--disabled btn--grey");
removeClass(elements, classnames)An extended implementation of Element.classList.remove(): removes classname(s) from single or multiple elements
Examples:
removeClass(btn, "btn--green");
removeClass(".btn", "btn--disabled btn--grey");
toggleClass(elements, classnames [, force = undefined])An extended implementation of Element.classList.remove(): toggles classname(s) from single or multiple elements
Examples:
toggleClass(btn, "btn--green", true);
toggleClass(".btn", "btn--disabled btn--grey");
getCookieValue(name)Finds cookie by name and returns its value.
Examples:
getCookieValue("_ga");
addEventListener(elements, eventNames, callback [, options/useCapture = false])Attaches the event handler. More about options/useCapture.
Examples:
addEventListener(btns, "click", doIt);
addEventListener([btn1, btn2], "click", doIt);
addEventListener(".btn", "click", doIt);
addEventListener(btn, "click focus", doIt);
addEventListener(btn, "click", doIt, { passive: true });
delegateEventListener(selector, eventNames, callback)Delegates the event handler (an equivalent to jQuery's .live()).
Examples:
delegateEventListener(".btn", "click", doIt);
delegateEventListener(".btn", "click focus", doIt);
In order to remove event handler, use document as a target element, e.g.:
delegateEventListener(".btn", "click", doIt); // delegate
removeEventListener(document, "click", doIt); // remove
// removing without using the callback function:
delegateEventListener(".btn", "click.btnDelegate", doIt); // delegate
removeEventListener(document, "click.btnDelegate"); // remove
removeEventListener(elements [, eventName = false, callback = false, options/useCapture = false])Removes the event handler. More about options/useCapture.
Examples:
removeEventListener(btn); // removes all event hanlders
removeEventListener(btn, "click"); // removes 'click' event handlers
removeEventListener(".btn", "click"); // removes 'click' event handlers
removeEventListener(btn, "click.thisIsNamespace"); // removes 'click.thisIsNamespace' event hanlders handlers
removeEventListener(btn, false, doIt); // removes all event handlers that are equal to 'doIt()'
removeEventListener(btn, "click", doIt); // removes 'click' event handlers that are equal to 'doIt()'
removeEventListener(btn, false, false, { passive: false }); // removes all event handlers that were attached together with the exact provided options
triggerEvent(elements, eventNames [, data = null])Triggers the event(s). data — data to pass to the event handler ((e) => {e.detail}). Doesn't work with click|focus|blur events.
Examples:
triggerEvent(btn, "click"); // triggers 'click' event
triggerEvent(btn, "click.thisIsNamespace"); // triggers 'click.thisIsNamespace' event
triggerEvent(btn, ".thisIsNamespace"); // triggers all events with 'thisIsNamespace' namespace
triggerEvent(btn, "customEvent"); // triggers custom event
triggerEvent(btn, "customEvent anotherCustomEvent"); // triggers custom event
triggerEvent(btn, "customEvent", "someData"); // triggers custom event and passed data
triggerEvent(btn, "customEvent", { some: "data" }); // triggers custom event and passed data
debounce(delay, fn)Debounces execution of a function.
Example:
window.addEventListener(
"resize",
debounce(500, () => {
// do something expensive here
})
);
throttle(delay, fn)Throttles execution of a function.
Example:
window.addEventListener(
"scroll",
throttle(500, () => {
// do something expensive here
})
);
loadScript(src, cache = true)Loads script file.
Returns: Promise.
Example:
loadScript("jquery.min.js", false)
.then(() => {
alert(typeof $);
})
.catch((error) => {
alert(`Error: ${error}. Try again.`);
});
getOffset(elements)Returns top/left offsets of an element
Returns: Object.
Example:
getOffset(container);
getOffset(".container");
serialPromises(...fns)Resolves promises sequentially.
Example:
serialPromises(
() => loadScript("jquery.min.js"),
() => loadScript("jquery-ui.min.js")
)
.then(() => {
$("ul").sortable();
})
.catch((error) => {
// error
});
getElements(elements [, source = document])Accepts String, Element, NodeList, Array and returns Array of elements.
hasClosest(element, matches)Based on how Element.closest() works. Returns true if element has the
closest ancestor (or itself) that matches the matches (element|selector).
getParents(element [, selector = '', until = null])Returns an Array of parents of element that matches the given selector
up until the until matching element|selector.
Smart Outline hides the outline when interacting with a mouse and brings it back when interacting with a keyboard.
