Saving to HTML per Chapter in Book

Hello,

I have thre questions, but they are related. 

1. How does one save per-chapter PDFs?
2. How does one save to HTML?
3. How does one save per-chapter HTML?

For some things, I have found example code. 

I have found examples showing how to open all the files in a book. 

var openedBook = app.ActiveBook

function openBookFiles(openedBook)

{

    var bookChapter=openedBook.FirstComponentInBook

    var chapterId = bookChapter.id

    while(chapterId)

    {  

        var chapterName = bookChapter.Name

        chapterId = openFile(chapterName)

        bookChapter = bookChapter.NextComponentInBook

        chapterId = bookChapter.id;

     }

}

That part works fine. 

I found an example for saving the whole book to PDF:

function savePdf(openedBook,pdfName)

{   

    var params = GetSaveDefaultParams()

    var returnParamsp =new PropVals()

    var ft = GetPropIndex(params, Constants.FS_FileType)

    params[ft].propVal.ival =Constants.FV_SaveFmtPdf

    openedBook.Save(pdfName, params, returnParamsp);

    return

}

That works fine too.

I tried to modify the above to save to a single HTML file.

function saveHTM(openedBook,htmName)

{   

    var params = GetSaveDefaultParams()

    var returnParamsp =new PropVals()

    var ft = GetPropIndex(params, Constants.FS_FileType)

    params[ft].propVal.ival =Constants.FV_SaveFmtFilter

    var params = GetSaveDefaultParams()

    var fth= GetPropIndex(params, Constants.FS_SaveFileTypeHint )

    params[fth].propVal.ival ="0001ADBEHTML"

    openedBook.Save(htmName, params, returnParamsp)

    return

}

The above does not work at all.

I would like to make the above work.

I would also like to save per-chapter PDFs and per-chapter HTML files.

However, I have not been able to figure out how to save per-chapter anything.
