@danielgindi/dom-utils

A collection of dom utilities. So you can work natively with the dom without dom frameworks.

All functions have appropriate JSDocs.

• lib/Css.js: A set of css helpers

  • getCssProps(el: Element, props: string[]): Object<string, string>
  • setCssProps(el: ElementCSSInlineStyle, props: Object<string, string>)
  • getElementWidth(el: Element, paddings: boolean = false, borders: boolean = false, margins: boolean = false): number
  • getElementHeight(el: Element, paddings: boolean = false, borders: boolean = false, margins: boolean = false): number
  • getPseudoElementWidth(el: Element, pseudo: string, paddings: boolean = false, borders: boolean = false, margins: boolean = false): number
  • getPseudoElementHeight(el: Element, pseudo: string, paddings: boolean = false, borders: boolean = false, margins: boolean = false): number
  • setElementWidth(el: Element, value: number, paddings: boolean = false, borders: boolean = false, margins: boolean = false)
  • setElementHeight(el: Element, value: number, paddings: boolean = false, borders: boolean = false, margins: boolean = false)
  • getElementOffset(el: Element): {top: number, left: number}
  • anchoredPosition(el: Element, xSpec: 'left'|'center'|'right'|'start'|'end'|string|number, ySpec: 'top'|'center'|'bottom'|string|number, size: {width: number: height: number}, rtl?: boolean): {left: number, top: number, right: number, bottom: number, xSpec: string|number, ySpec: string|number}

• lib/Dom.js: A set of dom helpers

  • createElement(tag: tag, attrs: Object<string, string>, children: Node|Node[]): Element
  • setElementAttrs(el: Element, attrs: Object<string, string>)
  • closestUntil(el: Element, selector: string, until?: Node): Node|null
  • prev(el: Element, selector: string): Element|null
  • next(el: Element, selector: string): Element|null

• lib/DomCompat.js: A set of compatibility functions, for several functions which are not available on all browsers

  • getRootNode(el: Node): Node|null
  • closest(el: Element, selector: string):Node|null
  • remove(el: Element)
  • before(before: ChildNode, ...nodes: (Node|string)[])
  • after(after: ChildNode, ...nodes: (Node|string)[])
  • prepend(parent: ParentNode, ...nodes: (Node|string)[])
  • append(parent: ParentNode, ...nodes: (Node|string)[])
  • scopedSelector(el: Element, selector: Element): Element|null
  • scopedSelectorAll(el: Element, selector: Element): NodeListOf<Element>
  • toggleClass(el: Element, className: string, toggle?: boolean): boolean

• lib/DomEventsSink.js: A class for registering/unregistering event listeners

  • add(el: EventTarget, eventName: string, handler: EventListenerOrEventListenerObject, optionsOrCapture?: boolean|AddEventListenerOptions): DomEventsSink
    event names support namespacing, where 'event.namespace'.
  • remove(el?: EventTarget, eventName?: string, handler?: EventListenerOrEventListenerObject, optionsOrCapture?: boolean|AddEventListenerOptions): DomEventsSink
    specify any argument as a filter for what to remove. specify '.namespace' event name in order to remove everything for a specific namespace.

• Touches.js: Touch helpers

  • bindTouchTap(el: Element, options: { distance: number = 9, handler: function(event: TouchEvent) }): { unbind: Function }
    This little function will manage touch events to detect a single tap.

• ScrollHelper.js: scroll helpers

  • You can use getScrollLeft/setScrollLeft to normalize the behavior of scrollLeft across the quirks of different browsers.
  • You can use getScrollHorz/setScrollHorz to record and restore scrollLeft positions on RTL elements, or to switch between ltr/rtl modes without loosing scroll position.
  • calculateNativeScrollLeftForLeft(el: Element, left: number, rtl?: boolean|undefined): number
    Calculates a native scrollLeft value for the specific element in the current browser.
    The input value is a standard scrollLeft value (taken with getScrollLeft).
    You will use this function instead of setScrollLeft if you want to animate to this value, or other kinds of manipulation. rtl is optional, you can pass it if you already have the 'direction' of the element and want to avoid that extra calculation.
  • getScrollLeft(el: Element, rtl?: boolean|undefined): number
    Fetches the scrollLeft value from an element, and normalizes across the different scroll methods to a unified method.
    You can later use setScrollLeft to set a value back to the element.
    rtl is optional, you can pass it if you already have the 'direction' of the element and want to avoid that extra calculation.
  • setScrollLeft(el: Element, value: number, rtl?: boolean|undefined)
    Sets the scrollLeft on an element.
    rtl is optional, you can pass it if you already have the 'direction' of the element and want to avoid that extra calculation.
    This function uses calculateNativeScrollLeftForLeft(...) to calculate the native scrollLeft.
  • calculateNativeScrollLeftForHorz(el: Element, left: number, rtl?: boolean|undefined): number
    Calculates a native scrollLeft value for an element, from an rtl-aware scrollLeft (i.e from getScrollHorz()). You will use this function instead of setScrollHorz if you want to animate to this value, or other kinds of manipulation. rtl is optional, you can pass it if you already have the 'direction' of the element and want to avoid that extra calculation.
  • getScrollHorz(el: Element, rtl?: boolean|undefined): number
    Gets an rtl-aware scrollLeft value from an element. The value will behave like a standard scrollLeft, except that for an rtl element it will have an rtl meaning, instead of being some crazy number.
    rtl is optional, you can pass it if you already have the 'direction' of the element and want to avoid that extra calculation.
  • setScrollHorz(el: Element, value: number, rtl?: boolean|undefined)
    Sets the scrollLeft on an element, with an rtl-aware value.
    rtl is optional, you can pass it if you already have the 'direction' of the element and want to avoid that extra calculation.
    This function uses calculateNativeScrollLeftForHorz(...) to calculate the native scrollLeft.
