Change text frame inside of pageItems in illustrator

[OhmsG]

I currently have a group.  In this group I have a pageItem with the name Order.

I can access this with the following:

  var orderItem = plateGroup.pageItems.getByName('Order');

This pageItem in illustraor has a text field.  How can I change the contens of this?

I thought something like this orderItem.textFrames.contents = 'hello'

But that does not work.  Any ideas on how I can achieve this?

I figured it out:

  orderItem.textRange.contents = 'hi here';

Hi,

why not simple

var orderItem = app.activeDocument.textFrames.getByName('Order');
// or
// var orderItem = plateGroup.textFrames.getByName('Order');
orderItem.contents = "my new contents";
