I would like to use UpdateListItems or something similar to allow my users to pass in some variable (e.g., a name) so I can use a caml query to find all items where SomeUserField = 'John B Smith' and replace that field with the value that they enter.
I see here: http://spservices.codeplex.com/wikipage?title=UpdateListItems that there is an "ID" parameter which makes it seem like I can only use this to update a single item.
Is it possible to have this change happen for all items where that query is true using only JavaScript/jQuery?
