示例

// Link to full sample: https://raw.githubusercontent.com/OfficeDev/office-js-snippets/prod/samples/powerpoint/shapes/get-shapes-by-type.yaml

// Gets the placeholder shapes in the slide.
await PowerPoint.run(async (context) => {
  // Get properties for every shape in the collection.
  const shapes: PowerPoint.ShapeCollection = context.presentation.slides.getItemAt(0).shapes;
  shapes.load("type,name");
  await context.sync();

  const placeholderShapes = [];
  console.log(`Number of shapes found: ${shapes.items.length}`);
  shapes.items.forEach((shape) => {
    if (shape.type === PowerPoint.ShapeType.placeholder) {
      // Load placeholderFormat property.
      // PowerPoint throws an exception if you try to load this property on a shape that isn't a placeholder type.
      shape.load("placeholderFormat");
      placeholderShapes.push(shape);
    }
  });
  await context.sync();

  console.log(`Number of placeholder shapes found: ${placeholderShapes.length}`);
  for (let i = 0; i < placeholderShapes.length; i++) {
    let currentPlaceholder: PowerPoint.PlaceholderFormat = placeholderShapes[i].placeholderFormat;
    let placeholderType = currentPlaceholder.type as PowerPoint.PlaceholderType;
    let placeholderContainedType = currentPlaceholder.containedType as PowerPoint.ShapeType;
    console.log(`Shape "${placeholderShapes[i].name}" placeholder properties:`);
    console.log(`\ttype: ${placeholderType}`);
    console.log(`\tcontainedType: ${placeholderContainedType}`);
  }
});

属性

containedType

获取占位符中包含的形状的类型。 有关详细信息,请参阅 PowerPoint.ShapeType 。 如果占位符为空,则返回 null

context

与对象关联的请求上下文。 这将加载项的进程连接到 Office 主机应用程序的进程。

type

返回此占位符的类型。 有关详细信息,请参阅 PowerPoint.PlaceholderType

方法

load(options)

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)

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)

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()

toJSON()

覆盖 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。) 虽然原始 PowerPoint.PlaceholderFormat 对象是 API 对象, toJSON 但该方法返回一个纯 JavaScript 对象, (类型化为 PowerPoint.Interfaces.PlaceholderFormatData) ,其中包含从原始对象加载的任何子属性的浅层副本。
