Select editor instance with no id

I have a page that will have dynamically added editor instances.
Should I be dynamically creating ID's for each, or can I just select the instances for use with getData() another way in Javascript?

The editors are all in a div wrapper that I can use to target the instance in Jquery or plain ol' JS, but I'm not sure the correct syntax to go about doing so with the CKEDITOR object.

It looks like everything I read after searching points to needing an ID and using a line such as:
CKEDITOR.instances['myID'].getData();
