require(["esri/widgets/Directions"], function(Directions) { /* code goes here */ });
Class: esri/widgets/Directions
Inheritance: Directions Widget Accessor
Since: ArcGIS API for JavaScript 4.6
beta

The Directions Widget provides a way to build driving and walking directions using ArcGIS online and custom Network Analysis Route services. Similar to how the RouteTask works, this widget generates a route finding a least-cost path between multiple points using a specified network. The resulting directions are displayed with detailed turn-by-turn instructions.

The widget wraps pre-built search functionality directly within it so all you need to do is reference the widget within your application. The routing service defaults to the Esri World Route service. This is a subscription based service available through ArcGIS Online. You can use this default or specify your own ArcGIS Server route service. Please see the routeServiceUrl property.

Any types of customizations made to the underlying functionality of the widget should be handled via its viewModel property.

Known Limitations

The Directions widget is currently in its beta release. It should be noted that it is not yet at full parity with the functionality provided in the 3.x version of the Directions widget and is subject to change.

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

Example:
var directionsWidget = new Directions({
  view: view
});
// Adds the Directions widget below other elements in
// the top right corner of the view
view.ui.add(directionsWidget, {
  position: "top-right",
  index: 2
});

Method Details

classes(classNames){String}inherited
Since: ArcGIS API for JavaScript 4.7

A utility method used for building the value for a widget's class property. This aids in simplifying CSS class setup.

Prior to version 4.7, there were various approaches towards setting CSS classes. These were dependent upon variables, such as whether the classes were:

  • a single static class,
  • multiple static classes, or
  • dynamic classes.

This helper method takes all of these approaches into account and simplifies it to use one single pattern to accommodate these multiple approaches.

Parameter:
classNames Array<(String|String[]|Object)>
repeatable

The class names.

Returns:
TypeDescription
StringThe computed class name.
See also:
Example:
// .tsx syntax showing how to set CSS classes while rendering the widget
render() {
  const dynamicIconClasses = {
    [CSS.myIcon]: this.showIcon,
    [CSS.greyIcon]: !this.showIcon
  };

  return (
    <div class={classes(CSS.root, CSS.mixin, dynamicIconClasses)} />
  );
}
destroy()inherited

Destroys the widget instance.

emit(type, event)inherited
Since: ArcGIS API for JavaScript 4.5

hasEventListener(type){Boolean}inherited

Indicates whether there is an event listener on the instance that matches the provided event name.

Parameter:
type String

The name of the event.

Returns:
TypeDescription
BooleanReturns true if the class supports the input event.
on(type, listener){Object}inherited

Registers an event handler on the instance. Call this method to hook an event with a listener.
