Select2 won't load remote json response

I have an API that is called by Select2 (v4.0.5) however the debug message in the console says:
Select2: The AJAX results did not return an array in the results key of the response.
When I review the documentation at Select2's documentation site I seem to be following it correctly. This is the javascript I use on the webpage:
$('#account_id').select2({
debug: true,
minimumInputLength: 3,
dataType: 'json',
ajax: {
url: '/api/account-query',
data: function (params) {
var query = {
search: params.term,
v: "new"
}
return query;
},
}
});
This is the response from the API (sensitive bits redacted):
{
"results": [{
"id": "redacted-1",
"text": "text redacted 1"
},{
"id": "redacted-2",
"text": "text redacted 2"
},{
"id": "redacted-3",
"text": "text redacted 3"
},{
"id": "redacted-4",
"text": "text redacted 4"
},{
"id": "redacted-5",
"text": "text redacted 5"
}]
}
If I take the select2 code and supply it with the static json response (without results prepended, just the array) it works just fine.
What am I missing?
Thanks!

You have to provide the processResults callback function so Select2 able to render result in proper way.
I have created a jsfiddle (https://jsfiddle.net/shcavbng/) demo that doing the same.
$('#account_id').select2({
debug: true,
minimumInputLength: 3,
dataType: 'json',
ajax: {
url: 'https://reqres.in/api/users',
data: function (params) {
console.log('params =>' , params);
var query = {
search: params.term,
v: "new"
}
return query;
},
processResults: function (data) {
console.log('results =>' , data);
data = data.data.reduce(function(o,i){o.push({id:i.id,text:i.first_name});return o;},[]);
console.log('results =>' , data);
return {
results: data
};
}
}
});

I figured it out, and as expected I was overlooking a simple aspect:
Content-Type header needed to be application/json vs text/html

JSON, Highcharts and Coldfusion json data

I have been trying to make this work for sometime and its I cannot seem to find the solution to make this work.
I am able to output JSON with my coldfusion CFC without issue, not I am trying to use this JSON with Highcharts.js. I have verified that the JSON is valid but highcharts seems to have an issue because in the series data there is double quotes surrounding the data. I've looked everywhere for a solution and I cannot seem to find any help that can set me on the right path. If I remove the double quotes from around the array in the series.data the chart loads in fine but I get away from it being dynamic.
Here is my JSON output from my CFC:`
{
"series": [{
"data": "[[Date.UTC(2017,05,21),2.9],[Date.UTC(2017,05,28),2.9],[Date.UTC(2017,06,04),3.1],[Date.UTC(2017,06,11),2.9]]",
"name": "ATC Main Pod A - B - C"
}, {
"data": "[[Date.UTC(2017,05,21),2.8],[Date.UTC(2017,05,28),2.6],[Date.UTC(2017,06,04),2.9],[Date.UTC(2017,06,11),2.9]]",
"name": "ATC Mays (ACB Blue)"
}, {
"data": "[[Date.UTC(2017,05,21),2.4],[Date.UTC(2017,05,28),2.6],[Date.UTC(2017,06,04),3],[Date.UTC(2017,06,11),3.2]]",
"name": "ATC Mays (ACB Purple)"
}, {
"data": "[[Date.UTC(2017,05,21),3.3],[Date.UTC(2017,05,28),3.3],[Date.UTC(2017,06,04),3.4],[Date.UTC(2017,06,11),3.3]]",
"name": "ATC R10 Pod D"
}, {
"data": "[[Date.UTC(2017,05,21),3.3],[Date.UTC(2017,05,28),3.4],[Date.UTC(2017,06,04),2.8],[Date.UTC(2017,06,11),1.9]]",
"name": "ATC TU Pod A - B"
}, {
"data": "[[Date.UTC(2017,05,21),2.9],[Date.UTC(2017,05,28),2.9],[Date.UTC(2017,06,04),3.1],[Date.UTC(2017,06,11),3.4]]",
"name": "CTRC 1st Floor"
}, {
"data": "[[Date.UTC(2017,05,21),2.9],[Date.UTC(2017,05,28),3.3],[Date.UTC(2017,06,04),3.2],[Date.UTC(2017,06,11),2.3]]",
"name": "CTRC 2nd Floor"
}]
}
Here is what my ajax call looks like:
function loadChartData(c){
$.ajax({type: "POST", url: "CFCs/survey.cfc", data: {method:"results_RLU", CENTERID: c},dataType: 'json',success: function(data){
options.series = data.series
var chart = new Highcharts.Chart(options)
}
});
}

Not a problem!
Simply iterate each item in the series and parse the data to valid JSON object.
Enjoy :)
function loadChartData(c){
$.ajax({type: "POST", url: "CFCs/survey.cfc", data: {method:"results_RLU", CENTERID: c},dataType: 'json',success: function(data){
options.series = data.series.map(function(item)
{
item.data = JSON.parse(item.data);
return item;
});
var chart = new Highcharts.Chart(options)
}
});
}

Return JSON results as JS array with AJAX?

Apologies in advance - I am new to this and so other answers have not been able to help me.
I have used AJAX to send data to a PHP script (part of a 3rd party API). The PHP script returns the results as JSON, but I have no idea how to format these on my HTML page.
Ultimately, I would like to save the JSON results as an array and then use JS/Jquery to format them on the page.
I am not sure how to modify the PHP and AJAX scripts to achieve this. Can anyone point me in the right direction?
My AJAX:
$.ajax({
type: 'POST',
url: 'calculator.php',
data: {toPostcode: toPostcodeValue, parcelLengthInCMs: parcelLengthInCMsValue, parcelHeighthInCMs: parcelHeighthInCMsValue, parcelWidthInCMs: parcelWidthInCMsValue, parcelWeightInKGs: parcelWeightInKGsValue},
success: function(data) {
<!--NOT SURE WHAT TO PUT HERE-->
}
})
PHP (after the calculator does its thing - not sure if it needs to be changed):
$serviceTypesJSON = json_decode($rawBody);
echo json_encode($serviceTypesJSON);
The expected JSON results should look like:
{
"services": {
"service" : [
{
"code": "AUS_PARCEL_REGULAR",
"name": "Parcel Post (your own packaging)",
"speed": 2,
"price": 6.95,
"max_extra_cover": 5000,
"extra_cover_rule": "100,1.5,1.5",
"icon_url": "http://test-static.npe.auspost.com.au/api/images/pac/regular_post_box.png",
"description": "Based on the size and weight you've entered",
"details": "Check our ",
"delivery_time": "Delivered in up to 3 business days",
"ui_display_order": 1,
"options": {
"option": [
{
"code": "AUS_SERVICE_OPTION_STANDARD",
"name": "Standard Service",
"price": "0.00",
"price_type": "static",
"option_type": "optional",
"ui_display_order": 1
},
{
"code": "AUS_SERVICE_OPTION_SIGNATURE_ON_DELIVERY",
"name": "Signature on Delivery",
"price": 2.95,
"price_type": "static",
"option_type": "optional",
"tooltip": "Signature on Delivery provides you with the peace of mind that your item has been delivered and signed for.",
"ui_display_order": 2,
"suboptions": {
"option": {
"code": "AUS_SERVICE_OPTION_EXTRA_COVER",
"name": "Extra Cover",
"option_type": "optional",
"price_type": "dynamic",
"tooltip": "Extra Cover provides cover for loss, damage or theft of your item and will fully compensate you to the value specified for your item.",
"ui_display_order": 1
}
}
}
]
}
},

You can do two things, if the return data is JSON use dataType: "json" in the AJAX call.
Edit 1
If you are using dataType: "json". Which is more preferred if you are sure the data return is JSON string. data variable in the success will directly give you the JSON object. I think you can access it like data['services'].
success: function (data) {
jsonObj = $.parseJSON(data);
//this gives you the inner onject of the return data
servicesObj = jsonObj.services;
}
Or you can just get the data then use jQuery.parseJSON() to parse the data string into JSON object.
$.ajax({
type: 'POST',
url: 'calculator.php',
data: {
toPostcode: toPostcodeValue,
parcelLengthInCMs: parcelLengthInCMsValue,
parcelHeighthInCMs: parcelHeighthInCMsValue,
parcelWidthInCMs: parcelWidthInCMsValue,
parcelWeightInKGs: parcelWeightInKGsValue
},
success: function (data) {
jsonObj = $.parseJSON(data);
//this gives you the inner onject of the return data
servicesObj = jsonObj.services; //or jsonObj["services"]
}
})

Your success function will never be called if you are using
echo json_encode(); in your php script.
You should add dataType:'json' after type:'POST' and then your success function will get called and will get the result returned by server in data

parse a result from AJAX request

I have this ajax request:
var rootURL = "http://localhost/myapp/api/api.php";
$.ajax({
type: 'GET',
url: rootURL + '/favourites',
dataType: "json",
success: function(list) {
},
error: function(list) {
}
});
and the api.php makes a query to DB and the encoded result
echo '{"result": ' . json_encode($result) . '}';
is like this:
{
"result": [
{
"ID": "1",
"username": "username1",
"name": "name1",
"year": "year1"
},
{
"ID": "2",
"username": "username2",
"name": "name2",
"year": "year2"
}
]
}
Now how can I get and print the two rows of the JSON result list in success callback in Javascript?
I tried this:
var decoded = JSON.parse( lista );
but I receive an error: JSON.parse: unexpected character at line 1 column 1 of the JSON data
Thanks

You dont't need to parse, just you need to iterate the array inside the result.
do like this:
success: function(list) {
$.each(list.result,function(index,item){
console.log(item);
});
}
FIDDLE DEMO

Don't call JSON.parse. jQuery does that for you when you say dataType: "json". list is an object. So just access list.result, which contains the result array.
Also, your PHP shouldn't build the JSON by hand like that. It should do:
echo json_encode(array('result' => $result));

display json data using xhrget (DOJO)

I am unable to figure out what is the problem with displaying json data..below is the code
var xhrGet1 = dojo.xhrGet({
url: "Page/",
handleAs: "json",
handle: function(response)
{
dojo.byId('json-data').innerHTML = response.questions[0];
}
});
Html
<div id='json-data'></div>
And my json file looks like this
{
"Info": {
"PURPOSE": ".... ",
},
"questions": [
{
"ID": 1,
"Question": "User ID",
"Information": "",
}, {
"ID": 2,
"Question": "Name",
"Information": "",
}
],
so on...any ideas??

The property handleAs : "json" in your xhr call makes the incoming json automatically eval'ed to javascript objects. So, you have to convert your javascript object back to string using JSON.stringify.
e.g. :
dojo.byId('json-data').innerHTML = JSON.stringify(response.questions[0]);
You can also use dojo.toJson for the same purpose. It uses json.stringify but has the benefit of having a second argument ("prettyprint"), allowing you to pretty-print out of the box, like this :
dojo.byId('json-data').innerHTML = dojo.toJson(response.questions[0], true);

wrap your JSON with PRE and CODE tags.
So:
dojo.byId('json-data').innerHTML = "<pre>code>" + response.questions[0] + "</code></pre>";
Also see: Display JSON as HTML for some libraries that can help you pretty-format your JSON when rendering in the browser
