How to loop through parsed JSON array using jquery .each()

Question

I have the following data which is being parsed and then I am looping through to attempt to get each state ID and name.

{
    "billing": {
        "ACT": "Australian Capital Territory",
        "NSW": "New South Wales",
        "NT": "Northern Territory",
        "QLD": "Queensland",
        "SA": "South Australia",
        "TAS": "Tasmania",
        "VIC": "Victoria",
        "WA": "Western Australia"
    },
    "shipping": {
        "ACT": "Australian Capital Territory",
        "NSW": "New South Wales",
        "NT": "Northern Territory",
        "QLD": "Queensland",
        "SA": "South Australia",
        "TAS": "Tasmania",
        "VIC": "Victoria",
        "WA": "Western Australia"
    }
}

data = '{"billing":{"ACT":"Australian Capital Territory","NSW":"New South Wales","NT":"Northern Territory","QLD":"Queensland","SA":"South Australia","TAS":"Tasmania","VIC":"Victoria","WA":"Western Australia"},"shipping":{"ACT":"Australian Capital Territory","NSW":"New South Wales","NT":"Northern Territory","QLD":"Queensland","SA":"South Australia","TAS":"Tasmania","VIC":"Victoria","WA":"Western Australia"}}';

data = jQuery.parseJSON( data );
billingData = data.billing;

$(billingData).each( function( key, value ) {
    console.log( key + value);
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

I am expecting the console to loop through each state ID and the label, but I get they key as 0 and the value as an object, I have also tried looping through the outputted object (contained in value from the original .each).

I have also tried looping through billingData[0].

Use $.each(billingData, fun... instead

You need to use jQuery.each() instead of .each() to do this work.

The .each() loop through jquery elements but jQuery.each() loop through array or object.

data = '{"billing":{"ACT":"Australian Capital Territory","NSW":"New South Wales","NT":"Northern Territory","QLD":"Queensland","SA":"South Australia","TAS":"Tasmania","VIC":"Victoria","WA":"Western Australia"},"shipping":{"ACT":"Australian Capital Territory","NSW":"New South Wales","NT":"Northern Territory","QLD":"Queensland","SA":"South Australia","TAS":"Tasmania","VIC":"Victoria","WA":"Western Australia"}}';

data = jQuery.parseJSON(data);
billingData = data.billing;

$.each(billingData, function(key, value) {
 console.log(key +": "+ value);
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

Thanks - that works! But why isn't what I am attempting to do the same result?

@bigdaveygeorge Because you trying to convert your json obj to jquery object ($(billingData)) and loop through it that isn't right.

billingData is not an array. It's an object. jQuery each will let you iterate through an object as though it were an array, or you could just use object methods:

data = '{"billing":{"ACT":"Australian Capital Territory","NSW":"New South Wales","NT":"Northern Territory","QLD":"Queensland","SA":"South Australia","TAS":"Tasmania","VIC":"Victoria","WA":"Western Australia"},"shipping":{"ACT":"Australian Capital Territory","NSW":"New South Wales","NT":"Northern Territory","QLD":"Queensland","SA":"South Australia","TAS":"Tasmania","VIC":"Victoria","WA":"Western Australia"}}';

data = jQuery.parseJSON(data);
billingData = data.billing;

Object.keys(billingData).forEach(function(key) {
  console.log(key + ": " + billingData[key])
})

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

There are two types of each:

$.each(array, function( key, value ) {

});

$('.element').each(function () {

});
