SharePoint 2013: JavaScript Object Model - Caml Query where list item is selected

Question

How could I use a caml query to only get the list items that are selected using the JavaScript Object Model?

<Where>
  <Eq>
     <FieldRef Name= ??? />
     <Value Type="Integer">1</Value>
  </Eq>
</Where>

For example, a user can select one, many, or all items in a list. I have a list on a page and I want to get the item(s) that are selected and do something with it. Thanks

You would not use a CAML query to do that. You can get the selected items using SP.ListOperations.Selection.getSelectedItems(ctx)

var ctx = SP.ClientContext.get_current();
var items = SP.ListOperation.Selection.getSelectedItems(ctx);
