Multi Dimensional Array | Object

Hi all

I have created a script that traverses all tables in a document and collects text strings that are formatted with a character style "Footnote_Marker".

(InDesign does not support Footnotes in Tables.)

Every found entry gives me 2 parts:

myPage (this is an object) and myFootnoteString (This is a string)

var myPageName = myPage.name;   <----- This gives me a human readable page number

The string can be something like "1" or "7" or "***"or "VISA only"

Many entries of "1" could be found on Page X, (The footnote will always mean the same thing in the complete catalogue, for example 1 = Made in Italy

So now I need to hold this data in a sensible construct.

I would like to have only one Array Key for the pages with many Secondary Key entries for the string.

Also if I find the Footnote marker "1" many times on the page it needs to go into the Array only once.

And I need to be able to alpha sort the Footnotes.

I already played with Arrays and Objects in Javascript but nothing works for me...

Appreciate your help

Regards

Romano

Hi Peter

Thank you very much!

I still try to understand what happens when we go into the arr

I guess page and notes is what I am looking for.

How do I know travers and output the arr data?

I end up with the keys, not the data that they hold, I think

main();

function main(){

    $.writeln("Checkpoint_0000");

    var known = {};

    var obj = {};

    myPageFootnoteDataFunction(known, obj);

    mySortPageFootnote(known, obj);

}

function myPageFootnoteDataFunction(known, obj){

    arr = [];

    for (i in obj) {

        arr.push ({page: Number(i), notes: obj.sort()});

    }

    arr.sort (function(a,b) {return a.page-b.page});

    outputDataArray(arr);

}   

function outputDataArray(arr){

    for(var a in arr){

        $.writeln("Array Key 01 [" + a + "]");       

        for(var b in arr){

            $.writeln("Array Key 02 [" + b + "]" );          

            for(var c in arr){

                $.writeln("Array Key 03 [" + c + "]" );

            }

        }

    }

}


You could write the array like this:

for (i = 0; i < arr.length; i++) {


   $.writeln ('Page: ' + arr.page + ', notes: ' + arr.notes.join(', '));


}

Here is some code I work with:

var myPageFootnoteData = {};

var myPage;

    var myFootnoteString;

    myPage = "aaaa";

    myFootnoteString = "AAAAA";

    addPageFootnote(myPageFootnoteData, myPage, myFootnoteString);

   

    myPage = "bbbb";

    myFootnoteString = "BBBBBB";

    addPageFootnote(myPageFootnoteData, myPage, myFootnoteString);

   

    myPage = "cccc";

    myFootnoteString = "CCCCCCCC";

    addPageFootnote(myPageFootnoteData, myPage, myFootnoteString);

   

    myPage = "dddd";

    myFootnoteString = "DD";

    addPageFootnote(myPageFootnoteData, myPage, myFootnoteString);

   

    myPage = "dddd";

    myFootnoteString = "12345";

    addPageFootnote(myPageFootnoteData, myPage, myFootnoteString);

   

    myPage = "dddd";

    myFootnoteString = "12345";

    addPageFootnote(myPageFootnoteData, myPage, myFootnoteString);

            $.writeln("Checkpoint_02");

    outputDataArray(myPageFootnoteData);

function addPageFootnote(myPageFootnoteData, myPage, myFootnoteString){

    $.writeln("This is my main object: " + myPageFootnoteData);

    $.writeln("This is the page: " + myPage);

    $.writeln("This is the footnote: " + myFootnoteString);

    //$.writeln("Cold call: show me the page: " + myPageFootnoteData[myPage].myPage);

    //var myPageHolder;

  var myPageHolder;

  var myFootnoteStringHolder;

    if(myPageHolder in myPageFootnoteData == false){

        myPageFootnoteData[myPageHolder] = {};

        $.writeln("It did not exist We insert this: " + myPage);

        myPageFootnoteData[myPageHolder] = myPage;

        $.writeln("OK show me the page: " + myPageFootnoteData[myPageHolder]);

    }

        $.writeln("Checkpoint_01a");

    if (myFootnoteStringHolder in myPageFootnoteData == false) {

        $.writeln("Checkpoint_01");

        //$.writeln("2OK show me the page: " + myPageFootnoteData[myPage]);

        myPageFootnoteData[myFootnoteStringHolder] = {};

        }

        if (myFootnoteStringHolder in myPageFootnoteData == false) {

                    $.writeln("Checkpoint_20");

        }

Here is a workable code.

I can create the first outer Array (it is actually a raw Object).

But the inner Array loop is not working at all.

It is possible that I don't understand the Array concept at all. So if you can give me a helping hand that would be greatly appreciated.

Hi Romano,

Maybe you could use a method along these lines:

Two objects: 'known' to keep track of notes placed on a page and and 'obj' to store your data

known = {};


obj = {};

For every found object, (a) if the page doesn't exist as a key, add a key, its value will be the string as a single-element array; (b) if the page key exists, add the string to the array if it's not yet in the array:

if (obj[myPage] === undefined) {


   obj[myPage] = [myString];


} else {


   if (!known[myPage+'/'+myString]) {


      obj[myPage].push(myString);


      known[myPage+'/'+myString] = true;


   }


}

Now you have an object with unsorted keys/page numbers, and each key has an array of unsorted arrays. You can't sort objects, so transfer it to an array. And while you're doing this, sort the arrays:

arr = [];


for (i in obj) {


   arr.push ({page: Number(i), notes: obj.sort()});


}

Then sort the array by page number:

arr.sort (function(a,b) {return a.page-b.page});

Hope this helps

Peter
