Current page about epubjs-rn HOT 4 CLOSED

me too, can't figure out how to get current page
need a props type to show/hide page number

from epubjs-rn.

You can get the current page by passing a function to the onLocationChange property.

It will return an object with the CFI, location in the book and the percentage complete.

Hi @fchasen ,

On the onLocationChange event, I only get (for example) this params:

end:{
  cfi:"epubcfi(/6/6[chapter-1]!/4/2/122/1:2)",
  displayed:{page: 5, totalPages: 6},
  href:"chapter-1.xhtml",
  index:2,
  location:13,
  percentage:1},
start:{
  cfi:"epubcfi(/6/6[chapter-1]!/4/2/112/1:308)",
  displayed:{page: 5, total: 6},
  href:"chapter-1.xhtml",
  index:2,
  location:10,
  percentage:0.7692307692307693}

How can I get the currentpage from the start field's CFI?

This futurepress/epub.js/wiki/Tips-and-Tricks talks about how to get the current page. Are you generate pagination for this purpose or is there any alternative to get the current page?

Thanks in advance.

Location is equivalent to a kindle / adobe page location, otherwise if you want the rendered paged you can use the displayed pages to show what page you are in for that chapter.

Generate pagination shouldn't be used on the client as it has to render the entire book.
