JavaScript/jQuery Map Options

Default Value: undefined

The value of this property will be passed to the accesskey attribute of the HTML element that underlies the UI component.

activeStateEnabled

Specifies whether the UI component changes its visual state as a result of user interaction.

Type:

Default Value: false

The UI component switches to the active state when users press down the primary mouse button. When this property is set to true, the CSS rules for the active state apply. You can change these rules to customize the component.

Use this property when you display the component on a platform whose guidelines include the active state change for UI components.

apiKey

Keys to authenticate the component within map providers.

Type:

|

Object

Default Value: { bing: '', google: '', googleStatic: '' }

If you have more than one map provider in your application, specify the keys in the object fields as shown below. Otherwise, you can assign the key directly to the apiKey property.

jQuery

$(function() {
    $("#mapContainer").dxMap({
        // ...
        apiKey: {
            bing: "MY_BING_MAPS_KEY",

NOTE

The value of this property cannot be changed dynamically.

autoAdjust

Specifies whether the UI component automatically adjusts center and zoom property values when adding a new marker or route, or if a new UI component contains markers or routes by default.

Type:

Default Value: true

If autoAdjust is enabled, zoom is set to the maximum value allowing all markers and routes to be displayed at the same time. The center is changed so that markers and routes are aligned with the UI component's center. Set the autoAdjust property to false to disable this behavior.

Note that the zoom level can only be automatically decreased to display all markers and routes. If the current zoom level allows all routes and markers to be displayed on the map, it remains unchanged.

center

An object, a string, or an array specifying which part of the map is displayed at the UI component's center using coordinates. The UI component can change this value if autoAdjust is enabled.

Type:

Object

|

|

Array<Number>

Raised Events: onOptionChanged

You can specify the center value in one of the following formats:

{ lat: 40.749825, lng: -73.987963}
"40.749825, -73.987963"
[40.749825, -73.987963]
"Brooklyn Bridge,New York,NY"

controls

Specifies whether or not map UI component controls are available.

Type:

Default Value: false

Assign a Boolean value to this property to enable or disable all controls at once - both the map navigation control and the map type control.
