Layers - ff6347/extendscript GitHub Wiki
This script takes a peek into the layers.
It makes use of the printable option to make the layer invisible.
It is NOT the visible option (the tiny eye on the layer panel).
have a deeper look into layers and their props here:

Lets get to the gist.
you can duplicate layers like everything else.
When you do that all the objects from the duplicated layer are also duplicated
*/

// set to preview mode

all the following actions cant be seen by the user because they happen on a
non displayed layer via the printable option NOT the visible option

This solves the problem: "Export a single layer as a new document in InDesign"
Written for this graphicdesign.stackexchange.com question.
// this script saves the current doc as a new one (with prompt)
// and removes all layers except for the one
// the user chooses in a drop down
// main function
var main = function() {
// if there is no doc
// abort
if (app.documents.length === 0) {
return;
}
var doc = app.activeDocument; // get the current active doc
var path = doc.filePath; // get the path
var name = prompt("Enter a name"); // get a name
if (name.length === 0) {
// if the user is to lazy add the date
name = (new Date()).toString();
}
var layernames = [];// to store the layer names
// loop the layer array
for (var i = 0; i < doc.layers.length; i++) {
layernames.push(doc.layers[i].name);// get the name
}
// save the doc as a new one
// under the new name
doc.save(new File(path + "/" + name + ".indd"));
// add a small dialog to select the layers
var diag = app.dialogs.add({
name: "Layers",
canCancel: true
});
// needs a column for the dropdown
var column = diag.dialogColumns.add();
// add the dropdown
var layerdd = column.dropdowns.add({
stringList: layernames,
selectedIndex: 0,
minWidth: 75
});
// show the dialog
if (diag.show() === true) {
var ndx = layerdd.selectedIndex;// get the index
diag.destroy(); // remove dialog
// move the layer to top
doc.layers[ndx].move(LocationOptions.AT_BEGINNING);
// remove all other layers
for (var j = doc.layers.length - 1; j >= 1; j--) {
doc.layers[j].remove();
}
}
// THE END
};
main(); // run that thing
