EditorItem | API Reference | ArcGIS Maps SDK for JavaScript 4.30

A predominantly read-only editable item that corresponds to the feature being updated. This class is used by the Editor widget to manage editing capabilities based on the provided layer and permissions set on it. It can be accessed through the Editor's view model's editorItems. Although the returned collection is primarily read-only, it is possible to modify its disabled property after construction. Also, it can be used in situations where custom functionality is used without the need to reference the Editor widget directly. In this scenario, the item can be constructed and used to determine the editing capabilities for a specific layer.

Examples

//Create the Editor widget with a feature layer and form template
const editor = new Editor({
 view: view,
 layerInfos: [{
   layer: featureLayer, // references an existing feature layer
   formTemplate: formTemplate // references an existing form template
 }]
});
// Access the EditorItem from the Editor's view model
const editorItem = editor.viewModel.editorItems.find(item => item.layer === featureLayer);
//Check if the item is editable and if so, disable it
const isEditable = editorItem?.editable;
if (isEditable) {
  editorItem.disabled = true;
}

// This creates a new EditorItem instance without the need to reference the Editor widget. It determines the editing capabilities for a specific layer.
const editorItem = new EditorItem({
 layer: featureLayer, // This property is required if creating a new instance of EditorItem
 layerInfo: featureLayerInfo
});

Property Details

capabilities Property capabilities EditorEditingCapabilitiesreadonly

The current editing capabilities for the provided layer.

declaredClass Inherited Property declaredClass Stringreadonly Inherited from Accessor

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

disabled Property disabled Boolean

Indicates whether to override editable to false. This property is typically used for temporary UI purposes. For example, if an item needs to be visible in the UI, but not editable.

Default Value:false

editable Property editable Booleanreadonly

Indicates whether at least one edit operation is supported in capabilities. It is primarily used for filtering layers eligible for editing. For UI purposes, specific permissions can still be confirmed using capabilities. Additionally, editable takes into account the value for disabled as a means to temporarily disable editing functionality.

Default Value:false

formTemplate Property formTemplate FormTemplatereadonly

A reference to the primary FormTemplate in use. A form template set within the Editor widget's layerInfos takes priority over a form template set directly on a FeatureLayer or SubtypeSublayer.

See also

hasInvalidFormTemplate Property hasInvalidFormTemplate Booleanreadonly

Indicates whether the primary FormTemplate has an unknown (invalid) field. Editing is typically disabled in this scenario.

Default Value:false

FeatureFormViewModel.valid

isTable Property isTable Boolean

Indicates whether the associated layer is of type Table.

Default Value:false

FeatureLayer.isTable

layer Property layer FeatureLayer |SubtypeSublayer

The FeatureLayer or SubtypeSublayer currently being edited.

layerInfo Property layerInfo LayerInfo

The layerInfo for the provided layer.

supportsCreateFeaturesWorkflow Property supportsCreateFeaturesWorkflow Booleanreadonly

Indicates whether the item supports starting a new create features workflow based on specific conditions set within the Editor.

Default Value:false

supportsUpdateWorkflow Property supportsUpdateWorkflow Booleanreadonly

Indicates whether the item supports starting a new update workflow based on specific conditions set within the Editor. This includes allowing attachments even when update is not allowed, or preventing edits when the layer or its parent are not visible.

Default Value:false

visible Property visible Booleanreadonly

Indicates whether the associated layer and its parent are visible.

Default Value:false
