How to access specific key:value for each object in array of objects using jQuery $.each?

Question

Schema (MongoDB):

key0: [
  {
     skey1: "sval1",
     skey2: "sval2"
  },
  {
     skey1: "sval3",
     skey2: "sval4"
  },
]

getJSON() Response:

[Object { skey1="val1", skey2="val2"}, Object { skey1="val3", skey2="val4"}]

Question:

How to access value of skey2 for each object?

jQuery (attempt):

my_var = results.key0

$.each(my_var, function(k,v) {
alert(v);
});

I think I need to do some sort of 'nested' $.each but not sure of the syntax.

This seems to work:

jsFiddle:

http://jsfiddle.net/rwone/Yg5cg/4/

// aim:  to alert value of 'skey2' for each object

myArray = [{ skey1:"val1", skey2:"val2"}, { skey1:"val3", skey2:"val4"}]

$.each(myArray, function(k,v) {
  alert(v.skey2);
});

Try:

var my_var = [{
    skey1: "sval1",
    skey2: "sval2"
}, {
    skey1: "sval3",
    skey2: "sval4"
}, ];
var len = my_var.length;
for (var i = 0; i < len; i++) {
    $.each(my_var[i], function (k, v) {
        alert("key"+k+"value"+v);
    });
}
