esri/form/FormTemplate
A FormTemplate formats and defines the content of a FeatureForm for a specific Layer or Graphic. A FormTemplate allows the user to access values from feature attributes when a feature in the view is selected.
The FormTemplate can be set directly on a FeatureLayer, a FeatureForm, or its view model. The template consists of various elements that display a specific type of form data.
// Create the Form template and pass in elements
const formTemplate = new FormTemplate({
title: "Inspector report",
description: "Enter all relevant information below",
elements: [groupElement] // Add all elements to the template
});
// Add a new feature form with grouped fields
const form = new FeatureForm({
container: "form",
groupDisplay: "sequential", // only display one group at a time
formTemplate: formTemplate // set it to template created above
});

-
Inherited from Accessor
Since: ArcGIS Maps SDK for JavaScript 4.25Accessor since 4.0, addHandles added at 4.25. -
Adds one or more handles which are to be tied to the lifecycle of the object. The handles will be removed when the object is destroyed.
// Manually manage handles const handle = reactiveUtils.when( () => !view.updating, () => { wkidSelect.disabled = false; }, { once: true } ); this.addHandles(handle); // Destroy the object this.destroy();
ParametershandleOrHandles WatchHandle|WatchHandle[]Handles marked for removal once the object is destroyed.
groupKey *optionalKey identifying the group to which the handles should be added. All the handles in the group can later be removed with Accessor.removeHandles(). If no key is provided the handles are added to a default group.
-
clone
clone(){FormTemplate}
-
Creates a deep clone of the FormTemplate class.
ReturnsType Description FormTemplate A deep clone of the FormTemplate instance.
-
Creates a new instance of this class and initializes it with values from a JSON object generated from an ArcGIS product. The object passed into the input
json
parameter often comes from a response to a query operation in the REST API or a toJSON() method from another ArcGIS product. See the Using fromJSON() topic in the Guide for details and examples of when and how to use this function.Parameterjson ObjectA JSON representation of the instance in the ArcGIS format. See the ArcGIS REST API documentation for examples of the structure of various input JSON objects.
ReturnsType Description * Returns a new instance of this class.
