DomEvent

@namespace DomEvent Utility functions to work with the DOM events, used by Leaflet internally.

Methods

Method	Returns	Description
`on(el: HTMLElement, types: String, fn: Function, context?: Object)`	`this`	Adds a listener function (`fn`) to a particular DOM event type of the
`on(el: HTMLElement, eventMap: Object, context?: Object)`	`this`	Adds a set of type/listener pairs, e.g. `{click: onClick, pointermove: onPointerMove}`
`off(el: HTMLElement, types: String, fn: Function, context?: Object)`	`this`	Removes a previously added listener function.
`off(el: HTMLElement, eventMap: Object, context?: Object)`	`this`	Removes a set of type/listener pairs, e.g. `{click: onClick, pointermove: onPointerMove}`
`off(el: HTMLElement, types: String)`	`this`	Removes all previously added listeners of given types.
`off(el: HTMLElement)`	`this`	Removes all previously added listeners from given HTMLElement
`stopPropagation(ev: DOMEvent)`	`this`	Stop the given event from propagation to parent elements. Used inside the listener functions:
`disableScrollPropagation(el: HTMLElement)`	`this`	Adds `stopPropagation` to the element's `'wheel'` events (plus browser variants).
`disableClickPropagation(el: HTMLElement)`	`this`	Adds `stopPropagation` to the element's `'click'`, `'dblclick'`, `'contextmenu'`
`preventDefault(ev: DOMEvent)`	`this`	Prevents the default action of the DOM Event `ev` from happening (such as
`stop(ev: DOMEvent)`	`this`	Does `stopPropagation` and `preventDefault` at the same time.
`getPropagationPath(ev: DOMEvent)`	`Array`	Returns an array containing the `HTMLElement`s that the given DOM event
`getPointerPosition(ev: DOMEvent, container?: HTMLElement)`	`Point`	Gets normalized pointer position from a DOM event relative to the
`getWheelPxFactor()`	`Number`	Gets the wheel pixel factor based on the devicePixelRatio
`getWheelDelta(ev: DOMEvent)`	`Number`	Gets normalized wheel delta from a wheel DOM event, in vertical
