Examples

// Link to full sample: https://raw.githubusercontent.com/OfficeDev/office-js-snippets/prod/samples/powerpoint/slide-management/add-slides.yaml

const chosenMaster = $("#master-id").val() as string;
const chosenLayout = $("#layout-id").val() as string;

await PowerPoint.run(async function(context) {
  // Create a new slide using an existing master slide and layout.
  const newSlideOptions: PowerPoint.AddSlideOptions = {
    slideMasterId: chosenMaster, /* An ID from `Presentation.slideMasters`. */
    layoutId: chosenLayout /* An ID from `SlideMaster.layouts`. */
  };
  context.presentation.slides.add(newSlideOptions);
  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

add(options)	Adds a new slide at the end of the collection.
getCount()	Gets the number of slides in the collection.
getItem(key)	Gets a slide using its unique ID.
getItemAt(index)	Gets a slide using its zero-based index in the collection. Slides are stored in the same order as they are shown in the presentation.
getItemOrNullObject(id)	Gets a slide using its unique ID. If such a slide does not exist, an object with an isNullObject property set to true is returned. 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's passed to it.) Whereas the original PowerPoint.SlideCollection object is an API object, the toJSON method returns a plain JavaScript object (typed as PowerPoint.Interfaces.SlideCollectionData) that contains an "items" array with shallow copies of any loaded properties from the collection's items.
