Circle

A class for drawing circle overlays on a map. Extends CircleMarker. It's an approximation and starts to diverge from a real circle closer to poles (due to projection distortion).

Usage example

L.circle([50.5, 30.5], 200).addTo(map);

Creation

Factory Description
L.circle(<LatLng> latlng, <Circle options> options?) Instantiates a circle object given a geographical point, and an options object which contains the circle radius.
L.circle(<LatLng> latlng, <Number> radius, <Circle options> options?) Obsolete way of instantiating a circle, for compatibility with 0.7.x code. Do not use in new applications or plugins.

Options

Option Type Default Description
radius Number Radius of the circle, in meters.
Option Type Default Description
stroke Boolean true Whether to draw stroke along the path. Set it to false to disable borders on polygons or circles.
color String '#3388ff' Stroke color
weight Number 3 Stroke width in pixels
opacity Number 1.0 Stroke opacity
lineCap String 'round' A string that defines shape to be used at the end of the stroke.
lineJoin String 'round' A string that defines shape to be used at the corners of the stroke.
dashArray String null A string that defines the stroke dash pattern. Doesn't work on Canvas-powered layers in some old browsers.
dashOffset String null A string that defines the distance into the dash pattern to start the dash. Doesn't work on Canvas-powered layers in some old browsers.
fill Boolean depends Whether to fill the path with color. Set it to false to disable filling on polygons or circles.
fillColor String * Fill color. Defaults to the value of the color option
fillOpacity Number 0.2 Fill opacity.
fillRule String 'evenodd' A string that defines how the inside of a shape is determined.
renderer Renderer Use this specific instance of Renderer for this path. Takes precedence over the map's default renderer.
className String null Custom class name set on an element. Only for SVG renderer.
Option Type Default Description
interactive Boolean true If false, the layer will not emit mouse events and will act as a part of the underlying map.
Option Type Default Description
pane String 'overlayPane' By default the layer will be added to the map's overlay pane. Overriding this option will cause the layer to be placed on another pane by default.

Events

Event Data Description
click MouseEvent Fired when the user clicks (or taps) the layer.
dblclick MouseEvent Fired when the user double-clicks (or double-taps) the layer.
mousedown MouseEvent Fired when the user pushes the mouse button on the layer.
mouseover MouseEvent Fired when the mouse enters the layer.
mouseout MouseEvent Fired when the mouse leaves the layer.
contextmenu MouseEvent Fired when the user right-clicks on the layer, prevents default browser context menu from showing if there are listeners on this event. Also fired on mobile when the user holds a single touch for a second (also called long press).
Event Data Description
add Event Fired after the layer is added to a map
remove Event Fired after the layer is removed from a map
Event Data Description
popupopen PopupEvent Fired when a popup bound to this layer is opened
popupclose PopupEvent Fired when a popup bound to this layer is closed
Event Data Description
tooltipopen TooltipEvent Fired when a tooltip bound to this layer is opened.
tooltipclose TooltipEvent Fired when a tooltip bound to this layer is closed.

Methods

Method Returns Description
setRadius(<Number> radius) this

Sets the radius of a circle. Units are in meters.

getRadius() Number

Returns the current radius of a circle. Units are in meters.

getBounds() LatLngBounds

Returns the LatLngBounds of the path.

Method Returns Description
toGeoJSON() Object

Returns a GeoJSON representation of the circle marker (as a GeoJSON Point Feature).

setLatLng(<LatLng> latLng) this

Sets the position of a circle marker to a new location.

getLatLng() LatLng

Returns the current geographical position of the circle marker

Method Returns Description
redraw() this

Redraws the layer. Sometimes useful after you changed the coordinates that the path uses.

setStyle(<Path options> style) this

Changes the appearance of a Path based on the options in the Path options object.

bringToFront() this

Brings the layer to the top of all path layers.

bringToBack() this

Brings the layer to the bottom of all path layers.

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.

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.

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.

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(…)
