Examples

// Link to full sample: https://raw.githubusercontent.com/OfficeDev/office-js-snippets/prod/samples/word/20-lists/insert-list.yaml

// This example starts a new list with the second paragraph.
await Word.run(async (context) => {
  const paragraphs: Word.ParagraphCollection = context.document.body.paragraphs;
  paragraphs.load("$none");

  await context.sync();

  // Start new list using the second paragraph.
  const list: Word.List = paragraphs.items[1].startNewList();
  list.load("$none");

  await context.sync();

  // To add new items to the list, use Start or End on the insertLocation parameter.
  list.insertParagraph("New list item at the start of the list", "Start");
  const paragraph: Word.Paragraph = list.insertParagraph("New list item at the end of the list (set to list level 5)", "End");

  // Set up list level for the list item.
  paragraph.listItem.level = 4;

  // To add paragraphs outside the list, use Before or After.
  list.insertParagraph("New paragraph goes after (not part of the list)", "After");

  await context.sync();
});

Properties

context

The request context associated with the object. This connects the add-in's process to the Office host application's process.

level

Specifies the level of the item in the list.

listString

Gets the list item bullet, number, or picture as a string.

siblingIndex

Gets the list item order number in relation to its siblings.

Methods

getAncestor(parentOnly)

Gets the list item parent, or the closest ancestor if the parent doesn't exist. Throws an ItemNotFound error if the list item has no ancestor.

getAncestorOrNullObject(parentOnly)

Gets the list item parent, or the closest ancestor if the parent doesn't exist. If the list item has no ancestor, then this method will return an object with its isNullObject property set to true. For further information, see *OrNullObject methods and properties.

getDescendants(directChildrenOnly)

Gets all descendant list items of the list item.

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.

set(properties, options)

Sets multiple properties of an object at the same time. You can pass either a plain object with the appropriate properties, or another API object of the same type.

set(properties)

Sets multiple properties on the object at the same time, based on an existing loaded object.

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's passed to it.) Whereas the original Word.ListItem object is an API object, the toJSON method returns a plain JavaScript object (typed as Word.Interfaces.ListItemData) that contains shallow copies of any loaded child properties from the original object.

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.

Method Details

getAncestor(parentOnly)

Gets the list item parent, or the closest ancestor if the parent doesn't exist. Throws an ItemNotFound error if the list item has no ancestor.

getAncestor(parentOnly?: boolean): Word.Paragraph;

Gets all descendant list items of the list item.

getDescendants(directChildrenOnly?: boolean): Word.ParagraphCollection;

Parameters

directChildrenOnly

boolean

Optional. Specifies only the list item's direct children will be returned. The default is false that indicates to get all descendant items.

load(options)

Queues up a command to load the specified properties of the object. You must call context.sync() before reading the properties.

load(options?: Word.Interfaces.ListItemLoadOptions): Word.ListItem;

Parameters

options
Word.Interfaces.ListItemLoadOptions

Provides options for which properties of the object to load.

Returns

load(propertyNames)

Queues up a command to load the specified properties of the object. You must call context.sync() before reading the properties.

load(propertyNames?: string | string[]): Word.ListItem;

Parameters

propertyNames

{ select?: string; expand?: string; }

propertyNamesAndPaths.select is a comma-delimited string that specifies the properties to load, and propertyNamesAndPaths.expand is a comma-delimited string that specifies the navigation properties to load.
