Google Slides and Apps Script

[eric_niedergang]

Hi,

I would like to create a very specific page numbering on my slides.

I would like to use Apps Scipt for this
But I find few sources

I can't get the position of a slide in the presentation?
There is an AutoText Class but I can't find any example to use it

Can you help me?
Thanks

Hi

Not sure if that will fit your needs but the example of the progress bar could help maybe ?

Hi Stephane,

Yes, I have already seen this example but it does not give me the solution for the numbers of each slide.

A simple trick:
I select some text on a slide,
I would like to know the number of this slide ?
How do I do this?

Thanks

Not sure to understand but when you are on edit mode when you are on a slide on the left nav bar, the selected slides have yellow border and there is number displayed at the top left.

You want something in presentation mode ?

No no, I speak about apps script.

 I write this in a bounded script in order to get the selected page

var currentPage = SlidesApp.getActivePresentation().getSelection().getCurrentPage();

 But, how I can retrieve the page number ? 

[Stephane_fr · Accepted solution]

This will work

function slidePageNumber() {
  let current =  SlidesApp.getActivePresentation().getSelection().getCurrentPage().getObjectId();

  const pages = SlidesApp.getActivePresentation().getSlides();
  for(let i = 0 ; i < pages.length ; i++){
    if(pages[i].getObjectId() == current){
      console.log(i+1)
      return ;
    }
  }
}

Yes, I'm OK with that

I thought there was a native function in the Google Slides API that allows you to retrieve the position of the Slide, but NO !! Very strange !

In order to continue my research on specific page numbering, I am also looking for example scripts that use the AutoText class

What can I do with this AutoText class?

Thanks

I don't know, on my side I don't invest  lot of time in apps script Google Slides project so I don't really know the functions available.
