load(propertyNames)

将命令加入队列以加载对象的指定属性。阅读属性前必须先调用 context.sync()。

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

参数

propertyNames: string | string[]

逗号分隔的字符串或指定要加载的属性的字符串数组。

load(propertyNamesAndPaths)

将命令加入队列以加载对象的指定属性。阅读属性前必须先调用 context.sync()。

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

参数

propertyNamesAndPaths: OfficeExtension.LoadOption

propertyNamesAndPaths.select 是一个逗号分隔的字符串，指定要加载的属性，是 propertyNamesAndPaths.expand 一个逗号分隔的字符串，指定要加载的导航属性。

toJSON()

重写 JavaScript toJSON() 方法，以便在将 API 对象传递给 JSON.stringify()时提供更有用的输出。 JSON.stringify (，反过来，调用toJSON传递给它的对象的方法。) 而原始Word.ContentControlCollection对象是 API 对象，toJSON该方法返回一个纯 JavaScript 对象， (类型为 Word.Interfaces.ContentControlCollectionData) ，其中包含一个“items”数组，其中包含集合项中任何已加载属性的浅表副本。

toJSON(): Word.Interfaces.ContentControlCollectionData;

Word.Interfaces.ContentControlCollectionData

track()

根据文档中的相应更改来跟踪对象，以便进行自动调整。此调用是 context.trackedObjects.add (thisObject) 的简写。如果跨 .sync 调用和“.run”批处理的顺序执行外部使用此对象，并在设置属性或调用对象方法时收到“InvalidObjectPath”错误，则需要在首次创建对象时将该对象添加到跟踪的对象集合。如果此对象是集合的一部分，则还应跟踪父集合。

track(): Word.ContentControlCollection;

untrack()

释放与此对象关联的内存（如果先前已跟踪过）。此调用是 context.trackedObjects.remove (thisObject) 的简写。拥有许多跟踪对象会降低主机应用程序的速度，因此请在使用完毕后释放所添加的任何对象。在内存发布生效之前，需要调用 context.sync() 。

untrack(): Word.ContentControlCollection;
