Přístup k ovládacím prvkům je vůbec špatný už v HTML 5. Tedy rozumná platforma umožňuje vytvářet vlastní ovládací prvky a ty vestavěné jsou vlastně konkrétní implementace takových prvků. Ovšem tady je to jinak - vlastní ovládací prvek sice nějak vytvoříte, ale zcela jiným způsobem a s řadou omezení.
Klasika ... ff uz davno neni co bejval ... byly casy, kdy vyvojari makali na browseru a picoviny pridavali tvurci pluginu ... dneska je to naopak ... vyvojari vyrabej picoviny (jako asocial api) a tvurci pluginu makaj na tom, jak to odstranit/vypnout/zlikvidovat ...
Mimochodem, predpokladam, ze ten hash/session/... co je defaultni soucasti toho "api", ma jednoznacne identifikovat prohlizec/uzivatele i kdyz neni nahodou na fb zrovna prihlasen/registrovan.
