a polyfill for the getBoxQuads API
npm i get-box-quads-polyfill
import { addPolyfill } from "get-box-quads-polyfill";
addPolyfill(window);
now you can use the Api on objects derived from "Node" :
document.body.getBoxQuads(...)
following API's are supported:
convertQuadFromNode(quad: DOMQuadInit, from: Element, options?: { fromBox: 'margin' | 'border' | 'padding' | 'content', toBox: 'margin' | 'border' | 'padding' | 'content', iframes?: HTMLIFrameElement[] })
convertRectFromNode(rect: DOMRectReadOnly, from: Element, options?: { fromBox: 'margin' | 'border' | 'padding' | 'content', toBox: 'margin' | 'border' | 'padding' | 'content', iframes?: HTMLIFrameElement[] })
convertPointFromNode(point: DOMPoint, from: Element, options?: { fromBox: 'margin' | 'border' | 'padding' | 'content', toBox: 'margin' | 'border' | 'padding' | 'content', iframes?: HTMLIFrameElement[] })
getBoxQuads(element: Element, options?: { box: 'margin' | 'border' | 'padding' | 'content', relativeTo: Element, iframes?: HTMLIFrameElement[] })
getElementSize(node: Node) -> cause of missing offsetWidth in other node types
the API do have a non standard parameter "iframes", in wich you can hand over iframe objects in wich your elments are embeded in. This is not needed in the browser native API, but in the polyfill, the element inside of an iframe could not access it's container.
gets the 4 transformed corner points of an Elment in DOM. Works only for HTMLElements. Limited support for SVG and MathML, cause of missing offsetLeft & offsetTop-Properties on SVGElement and MathMLElement (see issue: https://github.com/w3c/csswg-drafts/issues/10514)
