Oh and just to clarify (before someone else hits me on it), you don't
need the JQuery lookup in my example of using an existing JS object.
You can, however use the object directly to perform JQuery functions
on the object:
var columnID = document.getElmentById("columnId");
columnID.value=columnIDsArray;
