jQuery AutoComplete not rendering correctly

I have two jQuery autocomplete components on my site. Both nearly exactly the same however, one displays correctly and one doesnt.
The code for the working one is:
#Html.TextBoxFor(model => model.Part, new { #id = "txtPartCode" })
$('#txtPartCode').autocomplete({
minLength: 3,
source: function (request, response) {
$.ajax({
url: apiEndpoint + 'api/Part/Filtered/' + $('#txtPartCode').val(),
method: 'GET',
dataType: 'json',
contentType: 'application/json',
success: function (data) {
response(data);
}
});
}
});
The code for the failing one is:
#Html.TextBoxFor(model => model.ParentRequestId, new { #id = "txtParentRequest" })
$('#txtParentRequest').autocomplete({
minLength: 1,
source: function (request, response) {
$.ajax({
url: apiEndpoint + 'api/Request/' + $('#txtParentRequest').val(),
method: 'GET',
dataType: 'json',
contentType: 'application/json',
success: function (data) {
response(data);
}
});
}
});
As you can see they are very similar. The response from the API for the working one is ["string1", "string2", "string3"] and for the broken one is [1,2,3,4].
The jQuery libraries are included in my bundles so should be the same on all pages. I have used jquery.js, jquery-ui.js and jquery-ui.css.
I cant work out the difference between them as to why the one does not display correctly.
The broken one displays as follows:
Any help with this would be greatly appreciated. Please let me know if more info is required
EDIT - Solution But Why?
So the issue appeared to be that the jQuery Autocomplete component did not like an input of an array of integers.
This seems quite strange to me and I believe an autocomplete should be able to cope with integers. Does anybody know why this is or if there is a setting to handle it?

jquery-ui autocomplete would work good with String responses. Your response data should be a list of strings and not integers (as the value attribute for the input element is always a string).
Try converting the response data to string either at client side or server side. I prefer doing it at the client side.
$('#txtParentRequest').autocomplete({
minLength: 1,
source: function (request, response) {
$.ajax({
url: apiEndpoint + 'api/Request/' + $('#txtParentRequest').val(),
method: 'GET',
dataType: 'json',
contentType: 'application/json',
success: function (data) {
// Convert the integer list to a string list
var stringList = $.map(data, function(element){
return element + "";
})
response(stringList );
}
});
}
});

It's because JQuery autocomplete supports only two array formats as explained below:-
source Type:
Array or String or Function( Object request, Function
response( Object data ) ) Default: none; must be specified Defines the
data to use, must be specified. Independent of the variant you use,
the label is always treated as text. If you want the label to be
treated as html you can use Scott González' html extension. The demos
all focus on different variations of the source option - look for one
that matches your use case, and check out the code.
Multiple types supported: Array: An array can be used for local data.
There are two supported formats: An array of strings: [ "Choice1",
"Choice2" ] An array of objects with label and value properties: [ {
label: "Choice1", value: "value1" }, ... ] The label property is
displayed in the suggestion menu. The value will be inserted into the
input element when a user selects an item.
You can have a look at API documentation for more details:
http://api.jqueryui.com/autocomplete/
So as per me you can convert your array to string from backend or you can convert it by Javascript like this:-
$('#txtParentRequest').autocomplete({
minLength: 1,
source: function (request, response) {
$.ajax({
url: apiEndpoint + 'api/Request/' + $('#txtParentRequest').val(),
method: 'GET',
dataType: 'json',
contentType: 'application/json',
success: function (data) {
if(data!=null && data.length>0){
var numberArray=data.map(String);
response(numberArray);
//Or response(data.map(String));
}
}
});
}
});

How to get Google maps URL with a 'placeid' with AJAX?

I have a URL which I can open on browser and view the JSON data. The URL looks something like this:
https://maps.googleapis.com/maps/api/place/details/json?placeid=ChIJZeH1eyl344kRA3v52Jl3kHo&key=API_KEY_HERE
Now when I try to access this with jQuery AJAX, I fail to get any results, instead I get an error.
My AJAX call looks some like this:
$.ajax({
url: https://maps.googleapis.com/maps/api/place/details/json,
data: {
'placeid': 'ChIJZeH1eyl344kRA3v52Jl3kHo',
'key': 'API_KEY_HERE'
},
dataType: 'json',
success: function(response) {
alert(JSON.stringify(response));
},
error: function(error) {
alert(JSON.stringify(error));
}
});

var API_KEY = api_key;
var placeid = placeid;
var API_URL = `https://maps.googleapis.com/maps/api/place/details/json?placeid=${placeid}&key=${API_KEY}`
$.getJSON(API_URL, {
tags: placeid,
tagmode: "any",
format: "json"
},
function(data) {
alert(data);
});
If I build it up correctly, this should be the way to send the data correctly to the api, using the placeid inside the url string together with the api_key.
Then you use a getJSON instead of json because I assume you want to get the place data? Assuming to what you're doing in the ajax you made.
Maybe explain further what you mean with how to get google maps url with place id? Hope it helps you out :)

Can Mockjax handle single IDs Api from Json file

I'm using Mockjax for the first time to mock a Restful API which will return a series of data given an id. Right now i have a json file that has several Items, and i would like to have a function inside Mockjax (or where necessary) to return only the queried ID. how can I achieve this?
current code :
$.mockjax({
url: "/Api/Cases/{caseId}",
proxy: "/mocks/cases nuevo.json",
dataType: 'json',
responseTime: [500, 800]
});
$.ajax({
type: 'GET',
url: '/Api/Cases/',
data: {caseId: taskId},
success: function(data){
//use the returned
console.log(data);
}
});
current error:
GET http://localhost:8080/Api/Cases/?caseId=100 404 (Not Found)

Great question... yes, you can do this. But you'll have to write the functionality yourself using the response callback function and then making a "real" Ajax request for the file (instead of using the proxy option). Below I just make another $.ajax() call and since I have no mock handler setup for that endpoint, Mockjax lets it go through.
Note that setting up URL params is a little different than you suggest, here is what the mock setup looks like:
$.mockjax({
url: /\/Api\/Cases\/(\d+)/, // notice the regex here to allow for any ID
urlParams: ['caseID'], // This defines the first matching group as "caseID"
responseTime: [500, 800],
response: function(settings, mockDone) {
// hold onto the mock response object
var respObj = this;
// get the mock data file
$.ajax({
url: 'mocks/test-data.json',
success: function(data) {
respObj.status = 200;
// We can now use "caseID" off of the mock settings.urlParams object
respObj.responseText = data[settings.urlParams.caseID];
mockDone();
},
error: function() {
respObj.status = 500;
respObj.responseText = 'Error retrieving mock data';
mockDone();
}
});
}
});
There is one other problem with your code however, your Ajax call does not add the ID to the URL, it adds it to the query string. If you want to use that API endpoint you'll need to change your source code $.ajax() call as well. Here is the new Ajax call:
$.ajax({
type: 'GET',
url: '/Api/Cases/' + taskId, // this will add the ID to the URL
// data: {caseId: taskId}, // this adds the data to the query string
success: function(data){
//use the returned
console.log(data);
}
});
Note that this presumes the mock data is something like:
{
"13": { "name": "Jordan", "level": 21, "id": 13 },
"27": { "name": "Random Guy", "level": 20, "id": 27 }
}

What I have ended up doing, is: I have left the $.mockjax function untouched, and i have manipulated the data inside the ajax request, using jquery's $.grep function as follows:
$.ajax({
type: 'GET',
url: '/Api/Cases/' + taskId,
success: function(data){
//note you have to parse the data as it is received as string
data = JSON.parse(data);
var result = $.grep(data, function(e){ return e.caseId == taskId; });
//since i'm expecting only one result, i pull out the result on the 0 index position
requestedData = result[0];
}
});
The $.grep() method removes items from an array as necessary so that all remaining items pass a provided test see Jquery API, And since our test is that the caseId attribute of the element equals to the taksId variable sent, it will return all the elements that match the given Id, in this case, only one, this is why I've taken only the result on the 0 index position requestedData = result[0];
**Note: **
A more suited solution would be a mixture between what i've done and #jakerella 's answer, since their method implements the find element method inside the mockjacx function, and my function presumes a usual JSON response:
[{"caseId": 30,"name": "Michael"},{"caseId": 31,"name": "Sara"}]

Why does this AJAX POST fails with elasticsearch? [duplicate]

I am trying to send an Ajax POST request using Jquery but I am having 400 bad request error.
Here is my code:
$.ajax({
type: 'POST',
url: "http://localhost:8080/project/server/rest/subjects",
data: {
"subject:title":"Test Name",
"subject:description":"Creating test subject to check POST method API",
"sub:tags": ["facebook:work", "facebook:likes"],
"sampleSize" : 10,
"values": ["science", "machine-learning"]
},
error: function(e) {
console.log(e);
}
});
It Says: Can not build resource from request.
What am I missing ?

Finally, I got the mistake and the reason was I need to stringify the JSON data I was sending. I have to set the content type and datatype in XHR object.
So the correct version is here:
$.ajax({
type: 'POST',
url: "http://localhost:8080/project/server/rest/subjects",
data: JSON.stringify({
"subject:title":"Test Name",
"subject:description":"Creating test subject to check POST method API",
"sub:tags": ["facebook:work", "facebook:likes"],
"sampleSize" : 10,
"values": ["science", "machine-learning"]
}),
error: function(e) {
console.log(e);
},
dataType: "json",
contentType: "application/json"
});
May be it will help someone else.

In case anyone else runs into this. I have a web site that was working fine on the desktop browser but I was getting 400 errors with Android devices.
It turned out to be the anti forgery token.
$.ajax({
url: "/Cart/AddProduct/",
data: {
__RequestVerificationToken: $("[name='__RequestVerificationToken']").val(),
productId: $(this).data("productcode")
},
The problem was that the .Net controller wasn't set up correctly.
I needed to add the attributes to the controller:
[AllowAnonymous]
[IgnoreAntiforgeryToken]
[DisableCors]
[HttpPost]
public async Task<JsonResult> AddProduct(int productId)
{
The code needs review but for now at least I know what was causing it. 400 error not helpful at all.

Yes. You need to stringify the JSON data orlse 400 bad request error occurs as it cannot identify the data.
400 Bad Request
Bad Request. Your browser sent a request that this server could not
understand.
Plus you need to add content type and datatype as well. If not you will encounter 415 error which says Unsupported Media Type.
415 Unsupported Media Type
Try this.
var newData = {
"subject:title":"Test Name",
"subject:description":"Creating test subject to check POST method API",
"sub:tags": ["facebook:work", "facebook:likes"],
"sampleSize" : 10,
"values": ["science", "machine-learning"]
};
var dataJson = JSON.stringify(newData);
$.ajax({
type: 'POST',
url: "http://localhost:8080/project/server/rest/subjects",
data: dataJson,
error: function(e) {
console.log(e);
},
dataType: "json",
contentType: "application/json"
});
With this way you can modify the data you need with ease. It wont confuse you as it is defined outside the ajax block.

The question is a bit old... but just in case somebody faces the error 400, it may also come from the need to post csrfToken as a parameter to the post request.
You have to get name and value from craft in your template :
<script type="text/javascript">
window.csrfTokenName = "{{ craft.config.csrfTokenName|e('js') }}";
window.csrfTokenValue = "{{ craft.request.csrfToken|e('js') }}";
</script>
and pass them in your request
data: window.csrfTokenName+"="+window.csrfTokenValue

You need to build query from "data" object using the following function
function buildQuery(obj) {
var Result= '';
if(typeof(obj)== 'object') {
jQuery.each(obj, function(key, value) {
Result+= (Result) ? '&' : '';
if(typeof(value)== 'object' && value.length) {
for(var i=0; i<value.length; i++) {
Result+= [key+'[]', encodeURIComponent(value[i])].join('=');
}
} else {
Result+= [key, encodeURIComponent(value)].join('=');
}
});
}
return Result;
}
and then proceed with
var data= {
"subject:title":"Test Name",
"subject:description":"Creating test subject to check POST method API",
"sub:tags": ["facebook:work, facebook:likes"],
"sampleSize" : 10,
"values": ["science", "machine-learning"]
}
$.ajax({
type: 'POST',
url: "http://localhost:8080/project/server/rest/subjects",
data: buildQuery(data),
error: function(e) {
console.log(e);
}
});

I'm hoping this may be of use to those encountering 400 errors while using AJAX in Wordpress going forward. Even though this question is many years old, the solutions provided have all been programmatic, and I'm sure many have stepped through their code to repeatedly find it's correct, yet continue to find it is not working.
I found dozens of results asking how to resolve "WP AJAX request returning 400 Bad Request" or "WP AJAX request returning 0" and nothing today worked.
Googling "How do I fix 400 bad request on Wordpress?" finally resulted in the answer appearing from https://wp-umbrella.com/troubleshooting/400-bad-request-error-on-wordpress/
Clear your Web Browser Cache and Cookies
You may be surprised, but most 400 errors in WordPress can be fixed by clearing your browser's cache and cookies. Browser caches temporarily store images, scripts, and other parts of websites you visit to speed up your browsing experience.
Clearing both my cache and cookies saw the 400 Bad Request code disappear and results return AJAX results as expected.

Consuming API in javascript without using Node.js

i am leveraging CamFind's API for image recognition in my windows phone 8 app. On their site they have given an example for how to use the API with Node.js.. however i am writing a PhoneGap Windows Phone app and dont have this availble.
I would like to use just plain jquery/javascript to use this API.
Here's the example provided on their site:
var Request = unirest.post("https://camfind.p.mashape.com/image_requests")
.headers({
"X-Mashape-Authorization": "Z**********************"
})
.send({
"image_request[locale]": "en_US",
"image_request[language]": "en",
"image_request[device_id]": "<image_request[device_id]>",
"image_request[latitude]": "35.8714220766008",
"image_request[longitude]": "14.3583203002251",
"image_request[altitude]": "27.912109375",
"focus[x]": "480",
"focus[y]": "640",
"image_request[image]": "/tmp/file.path"
})
.end(function (response) {
console.log(response);
});
Here's how i am trying to do the same using jquery/ 'plain' javascript
$.ajax({
url: 'https://camfind.p.mashape.com/image_requests', // The URL to the API. You can get this by clicking on "Show CURL example" from an API profile
type: 'POST', // The HTTP Method
data: {
"image_request[locale]": "en_US",
"image_request[language]": "en",
"image_request[device_id]": "<image_request[device_id]>",
"image_request[latitude]": "35.8714220766008",
"image_request[longitude]": "14.3583203002251",
"image_request[altitude]": "27.912109375",
"focus[x]": "480",
"focus[y]": "640",
"image_request[image]": "http://exelens.com/blog/wp-content/uploads/2013/03/bmw-car-2013.jpg"
}, // Additional parameters here
datatype: 'json',
success: function(data) { alert(JSON.stringify(data)); },
error: function(err) { alert(err); },
beforeSend: function(xhr) {
xhr.setRequestHeader("X-Mashape-Authorization", "Z**********************");
}
});
Issue/Question:
When i do it through javascript/jquery - it seems to be complaining about missing image_request[image] attribute. It never hits the success block.
Am i doing something wrong in terms of how i transformed the Node.js API request example (1st block of code above) provided by CamFind VS. how i am doing trying to consumer the API through plain through Javascript (2nd block of code above)?
Thanks!!
Fyi, references i am using:
Consume an API in javacstipt: https://www.mashape.com/imagesearcher/camfind#!endpoint-1-Image-Request
CamFind API usage: https://www.mashape.com/imagesearcher/camfind#!endpoint-1-Image-Request

I know this is an old question but having stumbled across it whilst trying to solve it myself I thought I should answer it for the future.
The issue is this line:
"image_request[image]": "http://exelens.com/blog/wp-content/uploads/2013/03/bmw-car-2013.jpg"
It should be:
"image_request[remote_image_url]": "http://exelens.com/blog/wp-content/uploads/2013/03/bmw-car-2013.jpg"
So the complete code is:
$.ajax({
url: 'https://camfind.p.mashape.com/image_requests', // The URL to the API. You can get this by clicking on "Show CURL example" from an API profile
type: 'POST', // The HTTP Method
data: {
"image_request[locale]": "en_US",
"image_request[language]": "en",
"image_request[device_id]": "<image_request[device_id]>",
"image_request[latitude]": "35.8714220766008",
"image_request[longitude]": "14.3583203002251",
"image_request[altitude]": "27.912109375",
"focus[x]": "480",
"focus[y]": "640",
"image_request[remote_image_url]": "http://exelens.com/blog/wp-content/uploads/2013/03/bmw-car-2013.jpg"
}, // Additional parameters here
datatype: 'json',
success: function(data) { nowDoSomethingFun(data); },
error: function(err) { alert(err); },
beforeSend: function(xhr) {
xhr.setRequestHeader("X-Mashape-Key", "YOURKEY")
}
});
}

I am not familiar with this API but you might try formatting your data parameter like this:
data: {
image_request: {
locale: 'en_US',
language: 'en',
device_id: '<image_request[device_id]>',
latitude: '35.8714220766008',
longitude: '14.3583203002251',
altitude: '27.912109375',
image: 'http://exelens.com/blog/wp-content/uploads/2013/03/bmw-car-2013.jpg'
},
focus: {
x: '480',
y: '640'
}
}
