CoordinateConversion

require(["esri/widgets/CoordinateConversion"], function(CoordinateConversion) { /* code goes here */ });

Class: esri/widgets/CoordinateConversion

Inheritance: CoordinateConversion Widget Accessor

Since: ArcGIS API for JavaScript 4.7

The CoordinateConversion widget provides a way to display user cursor position either as map coordinates or as any of several popular coordinate notations. Additionally, the widget provides a way to convert user input coordinates into a Point.

Several common formats are included by default:

XY - Longitude, Latitude (WGS84)
MGRS - Military Grid Reference System
UTM - Universal Transverse Mercator
DD - Decimal Degrees
DDM - Degrees Decimal Minutes
DMS - Degrees Minutes Seconds
Basemap - X, Y in the coordinate system used by the current Basemap in the units used by the Basemap. Web Mercator is the standard for Esri-provided basemaps.

Additional formats can be created by a developer and made available through the widget.

For information about gaining full control of widget styles, see the Styling topic.

Example:

var ccWidget = new CoordinateConversion({
  view: view
});

// Adds widget in the bottom left corner of the view
view.ui.add(ccWidget, "bottom-left");

Constructors

new CoordinateConversion(properties)

Parameter:

properties Object

optional

See the properties for a list of all the properties that may be passed into the constructor.

Example:

// typical usage
var ccWidget = new CoordinateConversion({
  view: view
});

Property Details

container String|HTMLElement inherited

The ID or node representing the DOM element containing the widget. This property can only be set once. The following examples are all valid use cases when working with widgets.

Examples:

// Create the HTML div element programmatically at runtime and set to the widget's container
const basemapGallery = new BasemapGallery({
  view: view,
  container: document.createElement("div")
});

// Add the widget to the top-right corner of the view
view.ui.add(basemapGallery, {
  position: "top-right"
});

// Specify an already-defined HTML div element in the widget's container

const basemapGallery = new BasemapGallery({
  view: view,
  container: basemapGalleryDiv
});

// Add the widget to the top-right corner of the view
view.ui.add(basemapGallery, {
  position: "top-right"
});

// HTML markup
<body>
  <div id="viewDiv"></div>
  <div id="basemapGalleryDiv"></div>
</body>

// Specify the widget while adding to the view's UI
const basemapGallery = new BasemapGallery({
  view: view
});

// Add the widget to the top-right corner of the view
view.ui.add(basemapGallery, {
  position: "top-right"
});

conversions Collection<Conversion>

A Collection containing every Conversion that the widget is currently displaying.

currentLocation Point

Describes the location of the coordinates currently displayed by the widget as a Point. Setting this property will update all conversions.

declaredClass Stringreadonly inherited

The name of the class. The declared class name is formatted as esri.folder.className.

formats Collection<Format>

A Collection containing every Format that the widget is capable of displaying.

The default formats are basemap, dd, ddm, dms, mgrs, usng, utm, and xy.

goToOverride GoToOverride Since: ArcGIS API for JavaScript 4.8

This function provides the ability to override either the MapView goTo() or SceneView goTo() methods.

See also:

Example:

// The following snippet uses the Search widget but can be applied to any
// widgets that support the goToOverride property.
search.goToOverride = function(view, goToParams) {
  goToParams.options.duration = updatedDuration;
  return view.goTo(goToParams.target, goToParams.options);
};

id String inherited

The unique ID assigned to the widget when the widget is created. If not set by the developer, it will default to the container ID, or if that is not present then it will be automatically generated.

label String

The widget's default label.

mode String

Describes the current mode of the widget.

While in live mode, the widget will update as the cursor moves.
While in capture mode, the widget will update on mouse click and display a graphic marking the current location.

Possible Values:"live"|"capture"

Default Value:live

multipleConversions Boolean

If this property is set to true, multiple conversions can be displayed. For a simpler experience with only one conversion at a time, this property can be set to false.

Default Value:true

orientation String

Determines whether the widget should expand up or down. If set to auto the widget will be oriented based on its position in the view.

Possible Values:"auto"|"expand-up"|"expand-down"

Default Value:auto

requestDelay Number

The number of milliseconds of delay before conversion requests will be sent to the GeometryService. This only affects conversions that cannot be performed in the browser.

Default Value:300

view MapView|SceneView

A reference to the MapView or SceneView. Set this to link the widget to a specific view.

viewModel CoordinateConversionViewModel

The view model for this widget. The view model contains the logic that controls the Coordinate Widget's behavior. See the CoordinateConversionViewModel class to access all properties and methods on the widget.
