Can't add items to dynamically created page

[Guest]

I'm writing a Javascript script that will take a JSON file describing several page layouts (comprising one or more of text frames) and automatically create an InDesign document from it.

The script mostly works, but has a strange bug where the items destined for the last page always get put onto the last-but-one page. Any thoughts on why this might be happening? Any thoughts would be greatly appreciated!

Here's the minimal code:

// load JSON file using a parser into jsonObj
// add the required number of pages
for (var i = 0; i < jsonObj.PageLayouts.length - 1; i++) {
  app.activeDocument.pages.add(LocationOptions.AFTER, app.activeDocument.pages);
}
// create text frames using JSON doc on each page
var docPages = app.activeDocument.pages;
for (var i = 0; i < jsonObj.PageLayouts.length; i++) {
  for (var j = 0; j < jsonObj.PageLayouts.Placeholders.length; j++) {
  origin_x = jsonObj.PageLayouts.Placeholders.Frame.Origin.X / 10;
  origin_y = jsonObj.PageLayouts.Placeholders.Frame.Origin.Y / 10;
  height   = jsonObj.PageLayouts.Placeholders.Frame.Size.Height / 10;
  width    = jsonObj.PageLayouts.Placeholders.Frame.Size.Width / 10;
  bottom_x = origin_x + width;
  bottom_y = origin_y + height;
  var tf = docPages.textFrames.add({
  geometricBounds: [origin_y, origin_x, bottom_y, bottom_x]
  });
  $.writeln('  - Added rect (page ' : i + ' , rect ' + j + ')');
  }
}

And here's the sample JSON, which should create 3 pages, with 1 textFrames on the first 2 pages, and 2 textFrames on the 3rd page. Instead, I get 3 textFrames on the second page, and none on the last page.

{
    "PageLayouts": [
        {
            "Placeholders": [
                {
                    "Frame": {
                        "Origin": {
                            "X": 0,
                            "Y": 0
                        },
                        "Size": {
                            "Height": 2100,
                            "Width": 2970
                        }
                    } 
                }
            ]
        },
        {
            "Placeholders": [
                {
                    "Frame": {
                        "Origin": {
                            "X": 120,
                            "Y": 120
                        },
                        "Size": {
                            "Height": 1860,
                            "Width": 2730
                        }
                    }
                }
            ]
        },
        {
            "Placeholders": [
                {
                    "Frame": {
                        "Origin": {
                            "X": 120,
                            "Y": 1800
                        },
                        "Size": {
                            "Height": 200,
                            "Width": 2730
                        }
                    },
                },
                {
                    "Frame": {
                        "Origin": {
                            "X": 120,
                            "Y": 120
                        },
                        "Size": {
                            "Height": 1640,
                            "Width": 2730
                        }
                    }
                }
            ]
        }
    ]
}

This should be moved over to InDesign Scripting

try this:

  data, pls, i = 0, n = 0;

Thanks Loic! Much nicer code than mine. However it gave the same problem.

We figured it out - it's because the "Facing Pages" option is enabled, which means that odd-numbered pages from 3 onwards are on the right side of a double-page spread, and so the origin coordinates need to be changed to account for this. (Both scripts work fine when Facing Pages is disabled.)

All the best,

Apologies for this, I'm new to the forums and didn't see the separate Scripting forum. I'll make sure I post there from now on.
