L.Tooltip

Used to display small texts on top of map layers.

marker.bindTooltip("my tooltip text").openTooltip();

Note about tooltip offset. Leaflet takes two options in consideration for computing tooltip offseting:

the offset Tooltip option: it defaults to [0, 0], and it's specific to one tooltip. Add a positive x offset to move the tooltip to the right, and a positive y offset to move it to the bottom. Negatives will move to the left and top.
the tooltipAnchor Icon option: this will only be considered for Marker. You should adapt this value if you use a custom icon.

Factory	Description
`L.tooltip(<Tooltip options> options?, <Layer> source?)`	Instantiates a Tooltip object given an optional `options` object that describes its appearance and location and an optional `source` object that is used to tag the tooltip with a reference to the Layer to which it refers.

Option	Type	Default	Description
`pane`	`String`	`'tooltipPane'`	`Map pane` where the tooltip will be added.
`offset`	`Point`	`Point(0, 0)`	Optional offset of the tooltip position.
`direction`	`String`	`'auto'`	Direction where to open the tooltip. Possible values are: `right`, `left`, `top`, `bottom`, `center`, `auto`. `auto` will dynamicaly switch between `right` and `left` according to the tooltip position on the map.
`permanent`	`Boolean`	`false`	Whether to open the tooltip permanently or only on mouseover.
`sticky`	`Boolean`	`false`	If true, the tooltip will follow the mouse instead of being fixed at the feature center.
`interactive`	`Boolean`	`false`	If true, the tooltip will listen to the feature events.
`opacity`	`Number`	`0.9`	Tooltip container opacity.

▶ Options inherited from DivOverlay

Option	Type	Default	Description

Methods

▶ Popup methods inherited from Layer

Method	Returns	Description
`bindPopup(<String\|HTMLElement\|Function\|Popup> content, <Popup options> options?)`	`this`	Binds a popup to the layer with the passed `content` and sets up the neccessary event listeners. If a `Function` is passed it will receive the layer as the first argument and should return a `String` or `HTMLElement`.
`unbindPopup()`	`this`	Removes the popup previously bound with `bindPopup`.
`openPopup(<LatLng> latlng?)`	`this`	Opens the bound popup at the specificed `latlng` or at the default popup anchor if no `latlng` is passed.
`closePopup()`	`this`	Closes the popup bound to this layer if it is open.
`togglePopup()`	`this`	Opens or closes the popup bound to this layer depending on its current state.
`isPopupOpen()`	`boolean`	Returns `true` if the popup bound to this layer is currently open.
`setPopupContent(<String\|HTMLElement\|Popup> content)`	`this`	Sets the content of the popup bound to this layer.
`getPopup()`	`Popup`	Returns the popup bound to this layer.

▶ Tooltip methods inherited from Layer

Method	Returns	Description
`bindTooltip(<String\|HTMLElement\|Function\|Tooltip> content, <Tooltip options> options?)`	`this`	Binds a tooltip to the layer with the passed `content` and sets up the neccessary event listeners. If a `Function` is passed it will receive the layer as the first argument and should return a `String` or `HTMLElement`.
`unbindTooltip()`	`this`	Removes the tooltip previously bound with `bindTooltip`.
`openTooltip(<LatLng> latlng?)`	`this`	Opens the bound tooltip at the specificed `latlng` or at the default tooltip anchor if no `latlng` is passed.
`closeTooltip()`	`this`	Closes the tooltip bound to this layer if it is open.
`toggleTooltip()`	`this`	Opens or closes the tooltip bound to this layer depending on its current state.
`isTooltipOpen()`	`boolean`	Returns `true` if the tooltip bound to this layer is currently open.
`setTooltipContent(<String\|HTMLElement\|Tooltip> content)`	`this`	Sets the content of the tooltip bound to this layer.
`getTooltip()`	`Tooltip`	Returns the tooltip bound to this layer.

▶ Methods inherited from Layer

Method	Returns	Description
`addTo(<Map> map)`	`this`	Adds the layer to the given map
`remove()`	`this`	Removes the layer from the map it is currently active on.
`removeFrom(<Map> map)`	`this`	Removes the layer from the given map
`getPane(<String> name?)`	`HTMLElement`	Returns the `HTMLElement` representing the named pane on the map. If `name` is omitted, returns the pane for this layer.

▶ Methods inherited from Evented

Method	Returns	Description
`on(<String> type, <Function> fn, <Object> context?)`	`this`	Adds a listener function (`fn`) to a particular event type of the object. 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(<Object> eventMap)`	`this`	Adds a set of type/listener pairs, e.g. `{click: onClick, mousemove: onMouseMove}`
`off(<String> type, <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 event from the object. 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(<Object> eventMap)`	`this`	Removes a set of type/listener pairs.
`off()`	`this`	Removes all listeners to all events on the object.
`fire(<String> type, <Object> data?, <Boolean> propagate?)`	`this`	Fires an event of the specified type. You can optionally provide an data object — the first argument of the listener function will contain its properties. The event might can optionally be propagated to event parents.
`listens(<String> type)`	`Boolean`	Returns `true` if a particular event type has any listeners attached to it.
`once(…)`	`this`	Behaves as `on(…)`, except the listener will only get fired once and then removed.
`addEventParent(<Evented> obj)`	`this`	Adds an event parent - an `Evented` that will receive propagated events
`removeEventParent(<Evented> obj)`	`this`	Removes an event parent, so it will stop receiving propagated events
`addEventListener(…)`	`this`	Alias to `on(…)`
`removeEventListener(…)`	`this`	Alias to `off(…)`
`clearAllEventListeners(…)`	`this`	Alias to `off()`
`addOneTimeEventListener(…)`	`this`	Alias to `once(…)`
`fireEvent(…)`	`this`	Alias to `fire(…)`
`hasEventListeners(…)`	`Boolean`	Alias to `listens(…)`
