I have a custom list and when the user open the list item Display form there is a custom ribbon. This ribbon should be enabled if the current user is a member of a particular Group. Here is the caml query i used

var id = JSRequest.QueryString["ID"];

if (contextKey == "ApproveRequest") {
            var condition = '<View><Query><Where> <And> <Eq> <FieldRef Name=\"ID\"> </FieldRef> <Value Type=\"Integer\">' + id + ' </Value> </Eq> <Or><Membership Type="SPGroup" ID="447"><FieldRef Name=\"Author\"/></Membership><Eq><FieldRef Name= \"Author\"/><Value Type="Integer"><UserID Type="Integer"/></Value></Eq></Or> </And> </Where></Query></View>';
        }
