Access to a range within a multidimensional array

[tektippee]

My javascript array has values for "chapter", "paragraph",
"sentence", and the text of this sentence.
It looks like this:

book = [
[1, 1, 1, "Hi Mary."],
[1, 1, 2, "Today's Tuesday"],
[1, 1, 3, "We came back from fishing."],
...
...
[4, 26, 9, "We then took a nap."],
[4, 26, 10, "That was Tuesday"],
[4, 27, 1, "On Wednesday it was raining."],
...
...
[8, 84, 6, "Then he waved goodbye."]
];

How do I point into this array? That is, how do I
get to and sequentially process within this array?
The only parameters I get are the 1st and last chapter
numbers, i.e., the first element in the first and last
entries (inclusive) of the range.

E.g.
How would I process from [4, , , ] through [6, , , ]?
Or, e.g.,
all of chapter 4's records?

Thank you.

Hi

I not really understand what you want. For example this will output all sentences in the chapter interval 4-6 :

[b]for[/b] [teal]([/teal][b]var[/b] i[teal]=[/teal][purple]0[/purple][teal],[/teal]l[teal]=[/teal]book[teal].[/teal]length[teal];[/teal]i[teal]<[/teal]l[teal];[/teal]i[teal]++)[/teal]
  [b]if[/b] [teal]([/teal]book[teal][[/teal]i[teal]][[/teal][purple]0[/purple][teal]]>=[/teal][purple]4[/purple] [teal]&&[/teal] book[teal][[/teal]i[teal]][[/teal][purple]0[/purple][teal]]<=[/teal][purple]6[/purple][teal])[/teal] document[teal].[/teal][COLOR=darkgoldenrod]writeln[/color][teal]([/teal]book[teal][[/teal]i[teal]][[/teal][purple]3[/purple][teal]])[/teal]

You're hardcoding values which should be read as indices of arrays.

book = [
[
["Hi Mary.","Today's Tuesday","We came back from fishing"],
["This is chapter 1, paragraph 2"]
],

....

[
["We took a nap","That was on Thursday"],
["new paragraph","second sentence"]

]
];



chapter 4 can be found at
book[3]
chapter 6, paragraph 3 is:
book[5][2]
