Get content of textframe on specific layer and page

  • February 11, 2025

I've got an InDesign file with dozens of pages which I need to export as separate pages through a script. That part works fine but what I would like to do is name the exporting files after the content of a specific textframe on each page. The textframe is the only frame on a separate layer. What I currently have is this:

var _doc = app.activeDocument;
var _rangeFirst = parseInt(_range[0]) - 1;
var _rangeLast = parseInt(_range[_range.length - 1]);

var _textFrames = _doc.layers.item('myLayer').textFrames;
var _naming;
for (var k = _rangeFirst; k < _rangeLast; k++) {
    _naming = _doc.pages[k].pageItems[{itemLayer : 'myLayer'}].textFrames[0].contents;
alert(_naming)
}

I know that pageItems[{itemLayer : 'myLayer'}] does not work, VSC has been quite vocal about that ;). What is the correct syntax in this case? Any help is much appreciated.

Hi @ep_nna, similar to the answers you already have, here is the way I would approach it.

Or if you have them on a separate layer - name them:

 

 

and then use itemByName:

 

https://www.indesignjs.de/extendscriptAPI/indesign-latest/#TextFrames.html#d1e533551__d1e533820

 

 

for (var k = _rangeFirst; k < _rangeLast; k++) {
    _naming = _doc.pages[k].textFrames.itemByName("name_for_exported_file").contents;
alert(_naming)
}

You need to build a list/collection of the indexes - or names - of the pages from those TextFrames - and use in your loop.

You can go thru textframes and pick the right layer. Not very pretty but works.

 

for (var i = 0; i < _doc.pages[0].textFrames.length; i++ ){
if (_doc.pages[0].textFrames[i].itemLayer.name == 'myLayer'){
_naming = _doc.pages[0].textFrames[i].contents;
break;
}
}

 

Or thru layer items (prettier without the if-clause). The item order is not the same as page order. If you need order create an array of names and page numbers and arrange.

for (var i = 0; i < _doc.pages.length; i++){

    page_number = _doc.layers.item('myLayer').textFrames.item(i).parentPage.name;
    _naming = _doc.layers.item('myLayer').textFrames.item(i).contents;
}
