Word. Content Control Collection class

Examples

// Link to full sample: https://raw.githubusercontent.com/OfficeDev/office-js-snippets/prod/samples/word/90-scenarios/doc-assembly.yaml

await Word.run(async (context) => {
    const contentControls: Word.ContentControlCollection = context.document.contentControls.getByTag("customer");
    contentControls.load("text");

    await context.sync();

    for (let i = 0; i < contentControls.items.length; i++) {
      contentControls.items[i].insertText("Fabrikam", "Replace");
    }

    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.
items	Gets the loaded child items in this collection.

Methods

getById(id)	Gets a content control by its identifier. Throws an `ItemNotFound` error if there isn't a content control with the identifier in this collection.
getByIdOrNullObject(id)	Gets a content control by its identifier. If there isn't a content control with the identifier in this collection, then this method will return an object with its `isNullObject` property set to `true`. For further information, see *OrNullObject methods and properties.
getByTag(tag)	Gets the content controls that have the specified tag.
getByTitle(title)	Gets the content controls that have the specified title.
getByTypes(types)	Gets the content controls that have the specified types.
getFirst()	Gets the first content control in this collection. Throws an `ItemNotFound` error if this collection is empty.
getFirstOrNullObject()	Gets the first content control 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.
getItem(id)	Gets a content control by its ID.
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's passed to it.) Whereas the original `Word.ContentControlCollection` object is an API object, the `toJSON` method returns a plain JavaScript object (typed as `Word.Interfaces.ContentControlCollectionData`) 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.

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.ContentControlCollection;

Parameters

propertyNames: string | string[]

A comma-delimited string or an array of strings that specify the properties to load.

Returns

load(propertyNamesAndPaths)

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

load(propertyNamesAndPaths?: OfficeExtension.LoadOption): Word.ContentControlCollection;

Parameters

propertyNamesAndPaths: OfficeExtension.LoadOption

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.

Returns

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.ContentControlCollection object is an API object, the toJSON method returns a plain JavaScript object (typed as Word.Interfaces.ContentControlCollectionData) that contains an "items" array with shallow copies of any loaded properties from the collection's items.

toJSON(): Word.Interfaces.ContentControlCollectionData;

Returns

Word.Interfaces.ContentControlCollectionData

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.

track(): Word.ContentControlCollection;

Returns

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.

untrack(): Word.ContentControlCollection;

Returns
