pageHeight gives you the height of the field onstage in pixels, lineHeight
gives you the height of each line in pixels, and LineCount gives you the
total number of lines in the field. I'm not sure it would be any shorter
than the code you already have, but:
invisibleLines = member("field").lineCount -
member("field").pageHeight/member("field").lineHeight
For text, it's similar:
invisibleLines = member("text").line.count -
member("text").pageheight/member("text").fixedLineSpace
