[ On Style Events | Connect Style Event ]

All On Style event listeners receive a single event object. Additionally, the event object also contains a 'target' property whose value is the object which fired the event.

{
  error: <Error>
}

{
  layer: <Layer>
}

{
  opacity: <Number>

Property Details

The URL, when available, where the layer's attribution data is stored. (Added at v3.1)

attribute of the layer's node.

Provides credential information for the layer such as userid and token if the layer represents a resource that is secured with token-based authentication. This value is available after the layer has been loaded i.e. layer.loaded is true. (Added at v2.5)

Full extent as defined by the map service.

When true, the layer has attribution data. Use the

method to retrieve this data as JSON.

Known values: true | false

Default value: false

ID assigned to the layer. If not assigned, esri.Map assigns value. By default, the ID of the layer is "layer" followed by a number. The ID can be user defined only in the layer constructor.

• Setting the layer ID in the layer constructor.

  population = new esri.layers.ArcGISDynamicMapServiceLayer("http://myserver/arcgis/rest/population/MapServer/Layers", {id:"population"});
  

• Setting the layer ID after a layer is initialized.

  population.id = "population";

• Retrieving the layer ID.

  function getMapLayers() {
    for (var j=0, jl=myMap.layerIds.length; j<jl; j++) {
      var currentLayer = myMap.getLayer(myMap.layerIds[j]);
      alert("id: " + currentLayer.id);
    }
  }
  

Initial extent as defined by the map service.

Set if the layer failed to load. (Added at v3.9)

When the layer is loaded, the value becomes "true", and layer properties can be accessed. The

event is also fired.

Known values: true | false

Maximum visible scale for the layer. If the map is zoomed in beyond this scale, the layer will not be visible. A value of 0 means the layer does not have a maximum scale. (Added at v3.1)

Default value: 0

Minimum visible scale for the layer. If the map is zoomed out beyond this scale, the layer will not be visible. A value of 0 means the layer does not have a visible scale. (Added at v3.1)

Default value: 0

Opacity or transparency of layer. Values range from 0.0 to 1.0, where 0.0 is 100% transparent and 1.0 has no transparency.

Known values: 0.0 - 1.0

Default value: 1.0

Refresh interval of the layer in minutes. Non-zero value indicates automatic layer refresh at the specified interval. Value of 0 indicates auto refresh is not enabled. (Added at v3.7)

When true, the layer's attribution is displayed on the map. (Added at v3.1)

Known values: true | false

Default value: true

When true, the layer is suspended. A layer is considered to be suspended when one of the following is true:

• The layer is hidden.
• The layer is not visible at the current map scale.
• The layer is explicitly suspended by calling the Layer.suspend method.

Known values: true | false

Visibility of the layer.

Known values: true | false

Default value: true

When true, the layer is visible at the current map scale. (Added at v3.1)

Known values: true | false

Method Details

Adds a new attribute or changes the value of an existing attribute on the layer's node. Removes the attribute if the value is null or undefined. (Added at v3.7)

Asynchrously returns custom data for the layer when available. (Added at v3.1)

Returns reference to the map control the layer is added to. Returns null or undefined if it is not added to a map. (Added at v3.7)

Returns the layer's DOM node. (Added at v3.7)

Sets the visibility of the layer to "false". The layer is not removed, but it is hidden from view.

Returns true if the layer is visible at the given scale. (Added at v3.1)

Refreshes the map by making a new request to the server. In order to refresh the layer in this manner, setDisableClientCaching must be true. This ensures that map images are not cached on the client.

Resumes layer drawing. (Added at v3.1)

Set the maximum scale for the layer. (Added at v3.1)

Set the minimum scale for the layer. (Added at v3.1)

Sets the opacity of the layer. Values range from 0.0 to 1.0, where 0.0 is 100% transparent and 1.0 has no transparency.

layer.setOpacity(0.5);

Changes the layer's refresh interval to the given value (in minutes). Non-zero value sets up automatic layer refresh at the specified interval. Value of 0 stops auto refresh. (Added at v3.7)

Set the scale range for the layer. If minScale and maxScale are set to 0 then the layer will be visible at all scales. (Added at v3.1)

Sets the visibility of the layer. When true, the layer is visible.

Sets the visibility of the layer to "true".

Suspends layer drawing. (Added at v3.1)

Event Details

[ On Style Events | Connect Style Event ]

Fires when there is a problem retrieving a layer. Should be used in favor of onError. (Added at v3.5)

Fires after layer properties for the layer are successfully populated. This event must be successful before the layer can be added to the map. Should be used in favor of onLoad. (Added at v3.5)

Fires when the layer opacity has been changed, and returns an object with the opacity value. Should be used in favor of onOpacityChange. (Added at v3.5)

This event is fired when the layer's refreshInterval is modified. (Added at v3.7)

Fires when a layer resumes drawing. Should be used in favor of onResume. (Added at v3.5)

Fires when a layer's minScale and/or maxScale is changed. Should be used in favor of onScaleRangeChange. (Added at v3.5)

Fires when a layer's scale visibility changes. The scale visibility changes when a layer is initially visible and becomes invisible because the map scale does not intersect the layer's scale range or vice versa. Should be used in favor of onScaleVisibilityChange. (Added at v3.5)

Fires when a layer suspends drawing. Should be used in favor of onSuspend. (Added at v3.5)

Fires when a layer has finished updating its content. It is the responsibility of the subclass to determine when this event is fired. Should be used in favor of onUpdateEnd. (Added at v3.5)

Fires when a layer begins to update its content. It is the responsibility of the subclass to determine when this event is fired. Should be used in favor of onUpdateStart. (Added at v3.5)

Fires when the layer visibility has been changed, and returns an object with a Boolean visible property containing the new visibility value of the layer. Should be used in favor of onVisibilityChange. (Added at v3.5)
