Problem: Trebamo selektirati sve elementa #polje unutar svakog elementa klase .stavka koristeći this:

Ovo nam neće pomoći jer je pogrešno:

$(".stavka").each(function(){
 return $("this #polje").val();
});

Rješenje je $(this).find():

$(".stavka").each(function(){
 return $(this).find("#polje").val();
 });

Problem: lista ddl_automobili ima više opcija. Osim vrijednosti i naziva opcije tu je i rel atribut. Kod dohvata vrijednosti potrebno je dohvatiti rel atribut odabrane opcije.

Rješenje:


//vrijednost selektiranog rel
var relVrijednost = $("#ddl_automobili").find('option:selected').attr('rel'));
