L.DomEvent

DomEvent

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

Functions

Function	Returns	Description
`on(<HTMLElement> el, <String> types, <Function> fn, <Object> context?)`	`this`	Adds a listener function (`fn`) to a particular DOM event type of the element `el`. You can optionally specify the context of the listener (object the `this` keyword will point to). You can also pass several space-separated types (e.g. `'click dblclick'`).
`on(<HTMLElement> el, <Object> eventMap, <Object> context?)`	`this`	Adds a set of type/listener pairs, e.g. `{click: onClick, mousemove: onMouseMove}`
`off(<HTMLElement> el, <String> types, <Function> fn, <Object> context?)`	`this`	Removes a previously added listener function. If no function is specified, it will remove all the listeners of that particular DOM event from the element. Note that if you passed a custom context to on, you must pass the same context to `off` in order to remove the listener.
`off(<HTMLElement> el, <Object> eventMap, <Object> context?)`	`this`	Removes a set of type/listener pairs, e.g. `{click: onClick, mousemove: onMouseMove}`
`stopPropagation(<DOMEvent> ev)`	`this`	Stop the given event from propagation to parent elements. Used inside the listener functions: `L.DomEvent.on(div, 'click', function (ev) { L.DomEvent.stopPropagation(ev); });`
`disableScrollPropagation(<HTMLElement> el)`	`this`	Adds `stopPropagation` to the element's `'mousewheel'` events (plus browser variants).
`disableClickPropagation(<HTMLElement> el)`	`this`	Adds `stopPropagation` to the element's `'click'`, `'doubleclick'`, `'mousedown'` and `'touchstart'` events (plus browser variants).
`preventDefault(<DOMEvent> ev)`	`this`	Prevents the default action of the DOM Event `ev` from happening (such as following a link in the href of the a element, or doing a POST request with page reload when a `<form>` is submitted). Use it inside listener functions.
`stop(ev)`	`this`	Does `stopPropagation` and `preventDefault` at the same time.
`getMousePosition(<DOMEvent> ev, <HTMLElement> container?)`	`Point`	Gets normalized mouse position from a DOM event relative to the `container` or to the whole page if not specified.
`getWheelDelta(<DOMEvent> ev)`	`Number`	Gets normalized wheel delta from a mousewheel DOM event, in vertical pixels scrolled (negative if scrolling down). Events from pointing devices without precise scrolling are mapped to a best guess of 60 pixels.
`addListener(…)`	`this`	Alias to `L.DomEvent.on`
`removeListener(…)`	`this`	Alias to `L.DomEvent.off`
