Display JSON Data in HTML using Laravel 4 - php

Question

Please help me with my problem in displaying JSON data into my view..
my script is:
$('#supplierId').change(function(){
$.get("{{ url('api/dropdown')}}",
{ option: $(this).val() },
function(data) {
var firstnameID = $('#firstnameID');
$.each(data, function(index, element) {
firstnameID.val(element.first_name);
});
});
});
and my JSON reply is:
{"id":7,"first_name":"John","last_name":"Doe"}
the thing is when i tried to:
alert(element.first_name);
it says UNDEFINED, but when I:
alert(element);
it gives me the value of the last name which is Doe.. my question is how can I then access the other values like the ID and the first name..
EDITED:
this is my route:
Route::get('api/dropdown', function(){
$input = Input::get('option');
$supllier = Supplier::find($input);
returnResponse::json($supllier->select(array('id','first_name','last_name'))
->find($input));
});
Please help me with this one, This is my first time using JSON so im a bit confuse on how this works.
Best Regards

Answer 1

Why are you using each? This should work:
$('#supplierId').change(function(){
$.get("{{ url('api/dropdown')}}",
{ option: $(this).val() },
function(data) {
var firstnameID = $('#firstnameID');
firstnameID.val(data.first_name);
});
});

Ok, give this a try..
Explicitly state that what you're expecting back from the server is JSON using the dataType option in get().
$('#supplierId').change(function()
{
$.get("{{ url('api/dropdown')}}",
{ option: $(this).val() },
function(data)
{
var firstnameID = $('#firstnameID');
$.each(data, function(index, element)
{
firstnameID.val(element.first_name);
});
},
'json' // <<< this is the dataType
);
});
Now you should be able to access the data using the dot syntax:
console.log("last_name: " + element.last_name);
console.log("first_name: " + element.first_name);
console.log("id: " + element.id);
I would add another few lines, just to check that you're getting back what you expect to see:
console.log("NEW ELEMENT"); // << indicator in the console for your reference
console.log(element); // << the whole "element"
