javascript - Ruby toplevel == JS global object? -

-

coming ruby js, think it'd easy learn if compare , contrast between two. when stumbled ruby toplevel can't think of similar global object (window object) in javascript.

am correct in making assumption?

it's not similar in meaningful way except both objects act this/self outside context of other object. in other respect, quite different. there no useful way refer main outside of top level there window. global variables true global variables, , constants or methods defined in context of main not defined on main, on object class.

android - layout with fragment and framelayout replaced by another fragment and framelayout -

edit: so after comments below, revisted , realized hanging me up. imagine client list , client details activity started : public class clientsmainactivity extends fragmentactivity { @override public void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); //studiotabopenhelper db; setcontentview(r.layout.main_client_activity); } } so works great, starts main_client_activity (defined in layout below, , call activity when button on main screen clicked): intent intent = new intent(getactivity(), clientsmainactivity.class); startactivity(intent); easy issue is, clientsmainactivity not call oncreateview or anything, sets layout layout defines fragment, , listfragment. fine cause not trying pass clientsmainactivity , if have hypothetical activity like: sessionmainsactivity called when click on session edit of client, not calling sessionsmainactivity same way (starts activity sets alayout), want layout set defines...
