I got confused in accessing json data.. any help

Answer 1

You need to use Bracket notation .

Thus use

alert(tem[test][0].name);

instead of

alert(tem.test[0].name);

EDIT: As per comments. You should visit official jQuery.each() docs

$.each(tem[test],function(index, value){ 
    alert(value.name);
});
