I'm fairly new to scripting and I'm trying to write a script to add pages, inserting one after each existing page. We're doing postcards using a 4-up data merge. On the back of each card is the data merge/address (again, 4 to a page). Since the merge doesn't work on alternating pages, we want to do the merge first, then add the face pages afterward.
This is my code thus far:

var myPages = app.activeDocument.pages;
var myCounter = myPages.length-1;

for (i = myCounter; i >= 0; i--){

	myPages.add(LocationOptions.AFTER)...;

	}

On the line "myPages.add(LocationOptions.AFTER)..." I have tried every combination I can think of based on the CS3 Object Model that comes with Extend Script. Every one except the right one.

Many thanks for you help.

You add pages to a document:

app.activeDocument.pages.add()

Pages are added at the end of the document by default.

You add pages to a document, not to another page:

app.activeDocument.pages.add()

Pages are added at the end of the document by default.

Thanks, but I already knew that. This line from the ID Object model:
Pages.add(at:LocationOptions, reference:any, withProperties:Object):Page
would seem to imply that I can specify where to add pages. But I can't figure out how to make use of it.
To further clarify what I'm want to do, using a deck of cards as an analogy: Say I'm starting with all red cards. I want to add a black card after each red so that when I'm finished and you flip thru the deck you alternate between red and black.

I'm a beginner too (so take what Peter says more seriously than what I say!) but this works for me (select a text frame on the page you want to add a page after):

var myDocument = app.activeDocument;
var mySelection = app.selection[0];
var myPage = mySelection.parent;
myPages = myDocument.pages;
myPages.add(1634104421, myPage);

BTW, in my brief scripting career I've always found those numbers more reliable than the keyword enumerations.

I wonder if this works?

var myDocument = app.activeDocument;
var myPages = myDocument.pages;
var myCounter = 0;
for (var myHowMany = 0; myHowMany < myPages.length; myHowMany++){ myPage = myPages[myCounter]; myPages.add(LocationOptions.AFTER, myPage); myCounter = myCounter+2; if (myCounter > myPages.length-1) break;
       }

Tim,

Every time you add a page to the document, you change the myDoc.pages collection, and therefore, the value of myDoc.pages.length as well. To guard yourself against that, start at the back of the document and work your way to the front. This example adds a page before evry page in the document:

p = app.activeDocument.pages; 
for (i = p.length-1; i > -1; i--) 
   app.activeDocument.pages.add (LocationOptions.before, p[i]);

There's only one way to find out...

As I expected, Peter's solution is much more elegant than my own!
