Question

$obj = new Object();
$obj.surname = "smith";

$field_name = "surname";

alert($obj.$field_name); //error!!

Wth? How do I do this with js? I need to access all values in an object within a foreach but I can’t manage to access obj proprerties by reference!

Answer 1

$obj[$field_name] will do. It’s the same with the literal keys: you may use object['id'] as well as object.id – the latter is shorter, though. )
