Package:

word

Note

This API is provided as a preview for developers and may change based on feedback that we receive. Do not use this API in a production environment.

Contains a collection of Word.ListLevel objects.

Extends

OfficeExtension.ClientObject

Remarks

[ API set: WordApi BETA (PREVIEW ONLY) ]

Properties

context	The request context associated with the object. This connects the add-in's process to the Office host application's process.
items	Gets the loaded child items in this collection.

Methods

getFirst()	Gets the first list level in this collection. Throws an ItemNotFound error if this collection is empty.
getFirstOrNullObject()	Gets the first list level in this collection. If this collection is empty, then this method will return an object with its isNullObject property set to true. For further information, see *OrNullObject methods and properties.
load(options)	Queues up a command to load the specified properties of the object. You must call context.sync() before reading the properties.
load(propertyNames)	Queues up a command to load the specified properties of the object. You must call context.sync() before reading the properties.
load(propertyNamesAndPaths)	Queues up a command to load the specified properties of the object. You must call context.sync() before reading the properties.
toJSON()	Overrides the JavaScript toJSON() method in order to provide more useful output when an API object is passed to JSON.stringify(). (JSON.stringify, in turn, calls the toJSON method of the object that is passed to it.) Whereas the original Word.ListLevelCollection object is an API object, the toJSON method returns a plain JavaScript object (typed as Word.Interfaces.ListLevelCollectionData) that contains an "items" array with shallow copies of any loaded properties from the collection's items.
track()	Track the object for automatic adjustment based on surrounding changes in the document. This call is a shorthand for context.trackedObjects.add(thisObject). If you're using this object across .sync calls and outside the sequential execution of a ".run" batch, and get an "InvalidObjectPath" error when setting a property or invoking a method on the object, you need to add the object to the tracked object collection when the object was first created. If this object is part of a collection, you should also track the parent collection.
untrack()	Release the memory associated with this object, if it has previously been tracked. This call is shorthand for context.trackedObjects.remove(thisObject). Having many tracked objects slows down the host application, so please remember to free any objects you add, once you're done using them. You'll need to call context.sync() before the memory release takes effect.
