@namespace Event objects Whenever a class inheriting from `Evented` fires an event, a listener function will be called with an event argument, which is a plain object containing information about the event. For example: ```js map.on('click', function(ev) { alert(ev.latlng); // ev is an event object (MouseEvent in this case) }); ``` The information available depends on the event type: @miniclass Event (Event objects) @section The base event object. All other event objects contain these properties too. @property type: String The event type (e.g. `'click'`). @property target: Object The object that fired the event. @miniclass KeyboardEvent (Event objects) @inherits Event @property originalEvent: DOMEvent The original [DOM `KeyboardEvent`](https://developer.mozilla.org/en-US/docs/Web/API/KeyboardEvent) that triggered this Leaflet event. @miniclass MouseEvent (Event objects) @inherits Event @property latlng: LatLng The geographical point where the mouse event occured. @property layerPoint: Point Pixel coordinates of the point where the mouse event occured relative to the map layer. @property containerPoint: Point Pixel coordinates of the point where the mouse event occured relative to the map сontainer. @property originalEvent: DOMEvent The original [DOM `MouseEvent`](https://developer.mozilla.org/en-US/docs/Web/API/MouseEvent) or [DOM `TouchEvent`](https://developer.mozilla.org/en-US/docs/Web/API/TouchEvent) that triggered this Leaflet event. @miniclass LocationEvent (Event objects) @inherits Event @property latlng: LatLng Detected geographical location of the user. @property bounds: LatLngBounds Geographical bounds of the area user is located in (with respect to the accuracy of location). @property accuracy: Number Accuracy of location in meters. @property altitude: Number Height of the position above the WGS84 ellipsoid in meters. @property altitudeAccuracy: Number Accuracy of altitude in meters. @property heading: Number The direction of travel in degrees counting clockwise from true North. @property speed: Number Current velocity in meters per second. @property timestamp: Number The time when the position was acquired. @miniclass ErrorEvent (Event objects) @inherits Event @property message: String Error message. @property code: Number Error code (if applicable). @miniclass LayerEvent (Event objects) @inherits Event @property layer: Layer The layer that was added or removed. @miniclass LayersControlEvent (Event objects) @inherits Event @property layer: Layer The layer that was added or removed. @property name: String The name of the layer that was added or removed. @miniclass TileEvent (Event objects) @inherits Event @property tile: HTMLElement The tile element (image). @property coords: Point Point object with the tile's `x`, `y`, and `z` (zoom level) coordinates. @miniclass TileErrorEvent (Event objects) @inherits Event @property tile: HTMLElement The tile element (image). @property coords: Point Point object with the tile's `x`, `y`, and `z` (zoom level) coordinates. @property error: * Error passed to the tile's `done()` callback. @miniclass ResizeEvent (Event objects) @inherits Event @property oldSize: Point The old size before resize event. @property newSize: Point The new size after the resize event. @miniclass GeoJSONEvent (Event objects) @inherits Event @property layer: Layer The layer for the GeoJSON feature that is being added to the map. @property properties: Object GeoJSON properties of the feature. @property geometryType: String GeoJSON geometry type of the feature. @property id: String GeoJSON ID of the feature (if present). @miniclass PopupEvent (Event objects) @inherits Event @property popup: Popup The popup that was opened or closed. @miniclass TooltipEvent (Event objects) @inherits Event @property tooltip: Tooltip The tooltip that was opened or closed. @miniclass DragEndEvent (Event objects) @inherits Event @property distance: Number The distance in pixels the draggable element was moved by. @miniclass ZoomAnimEvent (Event objects) @inherits Event @property center: LatLng; The current center of the map @property zoom: Number; The current zoom level of the map @property noUpdate: Boolean; Whether layers should update their contents due to this event
