Unable to loop through complex JSON object with Jquery

Question

I am attempting to loop through the following JSON object without success:

[
    {
        "Count": 0,
        "GroupId": 1,
        "Icon": null,
        "Service": [
            {
                "Count": 0,
                "Icon": null,
                "ServiceId": 1,
                "Type": "Cat"
            },
            {
                "Count": 0,
                "Icon": null,
                "ServiceId": 2,
                "Type": "Dog"
            },
            {
                "Count": 0,
                "Icon": null,
                "ServiceId": 3,
                "Type": "Whale"
            }
        ],
        "Type": "Animal carcass removal"
    }
]

I need to get to the 'Service' object and append the Type to a dropdown list? I suspect I may need a each loop within a loop by cant seem tog et it right?

Any help would be appreciated.

Thanks

You should be able to do it with

$.each(data[0].Service, function () {
    $('select').append('<option val="'+this.Type+'">'+this.Type+'</option>')
});

where data is represents the object from your question.

By fallback, if no value is specified the title text is taken as value. And the OP was having problems with the looping (as I understood it), but I've altered the answer to be more explicit.

Try like this

            var data = [
    {
        "Count": 0,
        "GroupId": 1,
        "Icon": null,
        "Service": [
            {
                "Count": 0,
                "Icon": null,
                "ServiceId": 1,
                "Type": "Cat"
            },
            {
                "Count": 0,
                "Icon": null,
                "ServiceId": 2,
                "Type": "Dog"
            },
            {
                "Count": 0,
                "Icon": null,
                "ServiceId": 3,
                "Type": "Whale"
            }
        ],
        "Type": "Animal carcass removal"
    }
]

        for (i = 0; i < data[0].Service.length; i++) {
            $("#slct").append($("<option/>", { html: data[0].Service[i].Type, value: data[0].Service[i].ServiceId }));
        }

Html

<select id="slct">
</select>

$.each(a[0].Service,function (i,n){

  $("#ddl").append($("<option></option>").val(n.ServiceId).text(n.Type));


})

] 
var ser=jso[0].Service;
var output='';
for(var i in ser)
{
   output+='<option value="'+ser[i].Type+'">'+ser[i].Type+'</option>';
}
$('select').append(output)

var data = [{
"Count": 0,
    "GroupId": 1,
    "Icon": null,
    "Service": [{
    "Count": 0,
        "Icon": null,
        "ServiceId": 1,
        "Type": "Cat"
}, {
    "Count": 0,
        "Icon": null,
        "ServiceId": 2,
        "Type": "Dog"
}, {
    "Count": 0,
        "Icon": null,
        "ServiceId": 3,
        "Type": "Whale"
}],
    "Type": "Animal carcass removal"
}];

for(var d in data){
   var service = data[d].Service;
   for(var i = 0;i < service.length;i += 1){
       console.log(service[i].type);
   }
}
