require(["esri/arcgis/utils"], function(arcgisUtils) { /* code goes here */ });
Description
(Added at v2.0)
Utility methods to work with content from ArcGIS.com.
When coding legacy (non-AMD) style, there is no need to require the module. All methods and properties are available in the namespace. For example,
esri.arcgis.utils.createMap().Samples

Method Details
Create a map using information from an ArcGIS.com item. The information included in the response object returned to the callback depends on the version.
Note:
- If working with an item whose basemap layer does not have a geographic or Web Mercator spatial reference, you will need to make certain the
createMapmethod projects the item's extent using a geometry service or by passing in an extent usingoptions.mapOptions. If using a geometry service, it will either create a new GeometryService using theoptions.geometryServiceURLor it will use the GeometryService atesriConfig.defaults.geometryService(if it exists). - It is recommended to set
usePopupManager:trueif working with popups within the web map. One thing to note about this is that theclickEventHandleandclickEventListenerwill be undefined. Instead, use theMap.setInfoWindowOnClickto control visibility of the popup. - If the web map contains hosted feature services, the feature layer's default
modeisAUTO. When working with smaller amounts of features,SNAPSHOTmode is enabled. Whereas working with larger amounts of features enableson-demandmode.
{
map: <esri.Map>,
clickEventHandle, <undefined>
clickEventListener, <undefined>
itemInfo:{
item: <Object>,
itemData:<Object>,
errors: [<Object>]
}
}
The returned object contains the following properties.
{
map: <esri.Map>,
clickEventHandle, <Event Handler>
clickEventListener, <Function>
itemInfo:{
item: <Object>,
itemData:<Object>,
errors: [<Object>]
}
}
clickEventHandle: handle to the map event connection registered by createMap to display popups. Use this if you need to disconnect the handle at runtime.
require(["dojo/_base/connect", ... ], function(connect, ... ) {
connect.disconnect(response.clickEventHandle);
});
clickEventListener: Use this function to reconnect the popup event handler.
map.on("click", function(response) {
console.log(response.clickEventListener);
});Return type:
DeferredParameters:
< |
Required | An itemId for an ArcGIS.com item or the response object obtained from calling the arcgisUtils.getItem method. You can discover the item's unique ID by browsing to the item in ArcGIS.com then extracting the id from the item's URL. |
< |
Required | Container ID for referencing map. |
< |
Optional | Optional parameters that define the map functionality. See the Object Specifications table below for the structure of the options object. |
Object Specifications:
<
options>< |
Optional | The Bing Maps key, required if working with Microsoft Bing Maps. |
< |
Optional | Whether to allow layers in the created web map to be editable. If set to false, createMap() will create FeatureLayers where FeatureLayer.isEditable() returns false. This will override layers that would have otherwise been editable. This allows the FeatureLayer to load features optimally. Added at v3.11 |
< |
Optional | URL to the ArcGIS Server REST resource that represents a geometry service. If not using a geometry service from esriConfig.defaults.geometryService, you will need to specify this if the basemap layer is not geographic or Web Mercator.
For more information on constructing a URL, see the Services Directory and the REST API. |
< |
Optional | When true, webmap define popups will not display. |
< |
Optional | An optional array of objects which identify the layer using either matching id or url properties. It also has a Object mixin property that is mixed into the layer. Added at 3.14 |
< |
Optional | See the optional parameters for the esri.map constructor for more details. |
< |
Optional | If true and a map click event occurs, it may show the map's infoWindow.
If the infoWindow supports showing more than one feature, it will search
for all features in all layers of the map that have an infoTemplate configured, including
the sublayers of a ArcGIS tiled or dynamic map service.
When false, disables the Map.showInfoWindowOnClick behavior.
The default value is false.
(Added in version 3.10)
See also: Map.setInfoWindowOnClick(enabled). |
Sample:
var map, bingMapsKey;
require([
"esri/arcgis/utils",
"esri/map", "dojo/domReady!"
], function (arcgisUtils, Map) {
var deferred;
var createMapOptions = {
mapOptions: {
slider: true
},
usePopupManager: true, // since version 3.10
bingMapsKey: bingMapsKey,
geometryServiceURL: "http://sampleserver3.arcgisonline.com/ArcGIS/rest/services/Geometry/GeometryServer"
};
var webMapItemID = "c41d5f3b4e304806a047702fbfc2759e";
deferred = arcgisUtils.createMap(webMapItemID, "ui-map", createMapOptions);
deferred.then(function (response) {
map = response.map;
}, function (error) {
console.log("Error: ", error.code, " Message: ", error.message);
deferred.cancel();
});
});
Get details about the input ArcGIS.com item. An object with the following specification is passed to the callback:
{
item: <Object>,
itemData: <Object>
}
The information included in the response object returned to the callback depends on the version. View the Working with web maps help topic for details on the response object.Return type:
DeferredParameters:
< |
Required | The itemId for a publicly shared ArcGIS.com item. You can discover the item's unique ID by browsing to the item in ArcGIS.com then extracting the id from the item's URL. |
Can be used with
LayerList widget to get the layers list to be passed into the constructor. (Added at v3.14)Return type:
Object[]Parameters:
< |
Required | The object created from the resolved promise returned by createMap(). |
Sample:
arcgisUtils.createMap("df8bcc10430f48878b01c96e907a1fc3", "map").then(function(response){
var myWidget = new LayerList({
map: response.map,
layers: arcgisUtils.getLayerList(response)
},"layerList");
myWidget.startup();
});
});Can be used with
esri.dijit.Legend to get the layerInfos list to be passed into the Legend constructor. It will honor show/hide legend settings of each layer and will not include the basemap layers. See also: Legend layerInfos constructor option. (Added at v3.4)Return type:
Object[]Parameters:
< |
Required | Object returned by .createMap() in the .then() callback. |
Sample:
require(["esri/arcgis/utils"], function(arcgisUtils) {
arcgisUtils.createMap(webmapid, "map").then(function(response){
var legendLayers = arcgisUtils.getLegendLayers(response);
});
});
