Property Details

categories Property categories Array<(string|Array<string>)> Since: ArcGIS Maps SDK for JavaScript 4.8 PortalQueryParams since 4.0, categories added at 4.8.

An array of categories stored within the item. Use this property to filter the results from Portal.queryItems() and PortalGroup.queryItems(). It accepts an array of:

individual string elements or
an array of strings.

The query looks at each element within the array and performs a SQL AND operation on them. If the element is an array instead of a single string element, the elements within this array are read as OR. See the snippet below:

Note: String[] elements are only supported by ArcGIS Online and version 10.6.1 of Portal for ArcGIS Enterprise.

Example

// Query items with categories tagged as 'Basemaps' OR 'Imagery' AND 'People' OR 'Environment'
// i.e. (Basemaps || Imagery) && (People || Environment)
params.categories = [["Basemaps", "Imagery"], ["People", "Environment"]];

declaredClass Inherited Property declaredClass Stringreadonly Inherited from Accessor Since: ArcGIS Maps SDK for JavaScript 4.7 Accessor since 4.0, declaredClass added at 4.7.

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

extent Property extent Extentautocast

Only relevant when querying for PortalItems. When specified, restricts the results of the query to the extent defined here.

The spatial reference of the given extent must be WGS84 (wkid 4326) or Web Mercator (wkid 3857).

modified	search
username	user
created	user, group
