getSlideIndex

function getSlideIndex(
  slide: GoogleAppsScript.Slides.Slide,
  presentation?: GoogleAppsScript.Slides.Presentation | null
): number | null;

The slides are compared by their object id, so a slide read earlier is still recognised. A slide that belongs to another presentation, or has since been removed, gives null.

The slide comes first and the presentation is optional, the way getSlideByIndex and getSheetByIndex read: without one the active presentation is used, which is what a script bound to a deck already has. A standalone script has none, and then the answer is null rather than an error.

Parameters

Parameter	Type	Description
`slide`	`GoogleAppsScript.Slides.Slide`	The slide to look for.
`presentation` (optional)	`GoogleAppsScript.Slides.Presentation \\| null`	The presentation to look in. Without it the active presentation is used.

Returns

number | null — the zero-based position, or null when the slide is not there.

Examples

In the active presentation

const slide = SlidesApp.getActivePresentation().getSlides()[2];

getSlideIndex(slide); // => 2
