React Ajax 400 Bad Request on Rails-React - ajax

I am trying to send some data over \appointments via POST request on my handleFormSubmit function. But for some reason I am always getting a 400 Bad Request Error:
Here's my Appointments.jsx file:
import React from 'react';
import Appointment from './Appointment';
import AppointmentForm from './AppointmentForm';
import AppointmentsList from './AppointmentsList';
class Appointments extends React.Component {
constructor(props) {
super(props)
this.state = {
appointments: this.props.appointments,
title: 'Put your event title',
appointment_date: 'When would this happen?'
};
this.handleUserInput = this.handleUserInput.bind(this)
}
handleUserInput(obj_value){
this.setState(obj_value);
}
handleFormSubmit(){
let apppointment = {
title: this.state.title,
appointment_date: this.state.appointment_date
};
$.ajax({
type: "POST",
url: '/appointments',
data: { apppointment },
success: function(data){
console.log(data);
}
});
}
render(){
return(
<div>
<AppointmentForm title={this.state.title}
appointment_date={this.state.appointment_date}
onUserInput={this.handleUserInput}
onFormSubmit={this.handleFormSubmit}
/>
<AppointmentsList appointments={this.props.appointments} />
</div>
)
}
}
export default Appointments;
I am not sure yet but I think it has to do something with this code:
$.ajax({
type: "POST",
url: '/appointments',
data: { apppointment },
success: function(data){
console.log(data);
}
});
Any idea what do i need to do in order to fix this?

On the network tab, you must select the post request and then go to the parameters you are sending and check if you are sending the data and if it is the right structure.
This is how it looks like on Chrome there is where you check the data you are sending
Try modifying your handleFormSubmit
handleFormSubmit() {
let apppointment = JSON.stringify({
title: this.state.title,
appointment_date: this.state.appointment_date
})
$.ajax({
url: '/appointments',
type: "POST",
data: apppointment,
contentType: 'application/json'
})
}

meaby you can try with axios instance ajax

How to use JSON result from autocomplete as variable for another autocomplete

I would like to ask You for help mi to figure it out, how to use result of first Complete which is giving me a client number as #select_client_id in another autocomplete.
At one page, i'm selecting order from autocomplete list:
$( function() {
$( "#select_order" ).autocomplete({
source: function( request, response ) {
$.ajax({
url: "data/orderData.php",
type: 'post',
dataType: "json",
data: {
find_order_out: request.term
},
success: function( data ) {
response( data );
}
});
},
select: function (event, ui) {
$('#select_order').val(ui.item.label); // display the selected text
$('#select_order_id').val(ui.item.value); // save selected id to input
$('#select_client_id').val(ui.item.client_id);
return false;
}
});
});
Then there is another input field which is selecting packages for this order, where i`m using a client id, from first autocomplete:
$("#select_package").autocomplete({
source: function( request, response ) {
$.ajax({
url: "data/orderData.php",
type: 'post',
dataType: "json",
data: {
find_client_package_on_storage: request.term, client: client
},
success: function( data ) {
response( data );
console.log(client);
}
});
},
select: function (event, ui) {
$('.select_package').val(ui.item.label);
$('.select_package_id').val(ui.item.value);
return false;
}
});
For now, i've got only one client, so variable is declared by:
<script>
client="1";
</script>
How can i do it properly? :)
Well, it takes a little bit longer than normally, but it wasn't priory to figure it out :)
Answer is very simple :)
In #select_order autocomplete, i've add:
select: function (event, ui) {
$('#select_order').val(ui.item.label);
$('#select_order_id').val(ui.item.value);
$('#select_client_id').val(ui.item.client_id);
client_number=$("#select_client_id").val();
return false;
And at the end of body set a variable declaration:
<script>
let client_number = 0;
</script>
That solved my problem :)

call server-side REST function from client-side

In the case, on the server side have some archive restApi.js with REST functions. My REST functions works fine, i test with Prompt Command.
In my client side have some archive index.ejs, And I want to call with this file.
My restApi.js: Server-side
var Client = require('./lib/node-rest-client').Client;
var client = new Client();
var dataLogin = {
data: { "userName":"xxxxx","password":"xxxxxxxxxx","platform":"xxxx" },
headers: { "Content-Type": "application/json" }
};
var numberOrigin = 350;
client.registerMethod("postMethod", "xxxxxxxxxxxxxxxxxx/services/login", "POST");
client.methods.postMethod(dataLogin, function (data, response) {
// parsed response body as js object
// console.log(data);
// raw response
if(Buffer.isBuffer(data)){
data = data.toString('utf8');
console.log(data);
re = /(sessionID: )([^,}]*)/g;
match = re.exec(data);
var sessionid = match[2]
console.log(sessionid);
openRequest(sessionid, numberOrigin); // execute fine
}
});
function openRequest(sessionid, numberOrigin){
numberOrigin+=1;
var dataRequest = {
data: {"sessionID":sessionid,"synchronize":false,"sourceRequest":{"numberOrigin":numberOrigin,"type":"R","description":"Test - DHC","userID":"xxxxxxxxxx","contact":{"name":"Sayuri Mizuguchi","phoneNumber":"xxxxxxxxxx","email":"xxxxxxxxxxxxxxxxxx","department":"IT Bimodal"},"contractID":"1","service":{"code":"504","name":"Deve","category":{"name":"Developers"}}} },
headers: { "Content-Type": "application/json" }
};
client.post("xxxxxxxxxxxxxxxxxxxxxxxxx/services/request/create", dataRequest, function (data, response) {
// parsed response body as js object
// console.log(data);
// raw response
console.log(data);
});
}
My index.ejs: Client side
<html>
<head> ------------- some codes
</head>
<meta ------- />
<body>
<script>
function send() {
$.ajax({
type: "POST",
url: "restApi.js",
data: '{ sendData: "ok" }',
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (result) {
alert("successful!" + result.d);
}
});
}
</script>
<script src="restApi.js"></script>
</body>
</html>
I've try see others examples but does not work (Ajax).
And I need to know how to solved this, if have other Best practice for it, please let me knows.
In my console (Chrome) show if I call the ajax function:
SyntaxError: Unexpected token s in JSON at position 2 at JSON.parse (<anonymous>) at parse (C:\xxxxxxxxxxxxxxxxxxxxxxxxx\node_modules\body-parser\lib\types\json.js:88:17) at C:\xxxxxxxxxxxxxxxxxxxxxxxxx\node_modules\body-parser\lib\read.js:116:18
And if I click (BAD Request) show:
Obs.: Same error than app.js, but app.js works fine.
Cannot GET /restApi.js
In the case the file restApi.js Is a folder behind the index.
Folder:
Obs.: public folder have the index.ejs
Your problem is bad url. In case if you have fiule structure like this you have to point as shown in image
Based on the error I think the data you are posting via AJAX is not in correct syntax.
Change function send() as following.
function send() {
var obj = { "sendData" : "ok" };
$.ajax({
type: "POST",
url: "restApi.js",
data: obj,
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (result) {
alert("successful!" + result.d);
}
});
}
This should resolve the error you are facing.
Try this now...
function send() {
var obj = {
sendData : "ok"
};
$.ajax({
type: "POST",
url: "Your url",
data: obj,
dataType: "json",
success: function (result) {
alert("successful!" + result.d);
},
error: function (error) {
console.log("error is", error); // let us know what error you wil get.
},
});
}
Your url is not pointing to js/restapi js.
and what code do you have in js/restapi js?
if your action page is app js you have to put it in url.
url:'js/restapi.js',

ExtJs 4.1 : How to send json data in the request body using Ext.Ajax.request()?

I would like to send json data using Ext.Ajax.request() then access it in ASP.NET using Request.InputStream which is the content of the request body. I need a way to tell ExtJs to write the data in the request body as it is done while using an Ext.data.proxy.Ajax.
Specify POST method and just use the request's jsonData config:
Ext.Ajax.request({
url: 'myUrl',
method: 'POST',
params: {
requestParam: 'notInRequestBody'
},
jsonData: 'thisIsInRequestBody',
success: function() {
console.log('success');
},
failure: function() {
console.log('woops');
}
});
If you want a record written as JSON you can use a JSON writer like this also.
var writer = Ext.create('Ext.data.writer.Json'),
record = Ext.getStore('SomeStoreID').first();
Ext.Ajax.request({
url: 'myUrl',
method: 'POST',
params: {
requestParam: 'notInRequestBody'
},
jsonData: writer.getRecordData(record),
success: function() {
console.log('success');
},
failure: function() {
console.log('woops');
}
});

Use Ajax and JsonResult in ASP.NET MVC 3

I need to get string array or list with ajax and Action, this is my Implementation:
This is my html Dom of view of Index action in AccessMenuController:
<div class="RoleAccess">
<select name="RoleDropDown">
<option value="0">Select Role</option>
<option value="61AD3FD9-C080-4BB1-8012-2A25309B0AAF">AdminRole</option>
<option value="8A330699-57E1-4FDB-8C8E-99FFDE299AC5">Role2</option>
<option value="004E39C2-4FFC-4353-A06E-30AC887619EF">Role3</option>
</select>
</div>
My Controller:
namespace MyProject.Areas.GlobalAccess.Controllers {
public class AccessMenuController : Controller {
public ActionResult Index() { return View();}
[HttpPost]
public JsonResult RoleDropDownChanged(string roleId) {
Guid RoleId = new Guid(roleId);
//Some implement
List<string> actions = new List<string>();
for(int i = 0; i <= 10; i++)
actions.Add(i.ToString());
return Json(actions.ToArray(), JsonRequestBehavior.AllowGet);
}
}
}
and the script:
$(document).ready(function () {
//Handle Checks of Actions by RoleName Changed
$('div.RoleAccess select').change(function () {
RoleChangeHandler();
});
function RoleChangeHandler() {
$.ajax({
url: '#Url.Action("RoleDropDownChanged")',
type: 'POST',
data: { 'roleId': '61AD3FD9-C080-4BB1-8012-2A25309B0AAF' },
dataType: 'json',
processData: false,
contentType: 'application/json; charset=utf-8',
success: function (data) { SuccessRoleChangeHandler(data); },
error: OnFailRoleChangeHandler
});
return false;
}
function SuccessRoleChangeHandler(data) {
alert("in success role change");
}
function OnFailRoleChangeHandler(result) {
alert('in OnFailRoleChangeHandler');
}
And the problem is with all change of dropdown just Onfail function run and alert me "in OnFailRoleChangeHandler", also I check the RoleDropDownChanged Action with breakpoint and that never run, where is the problem?
UPDATE
when I load the page by chrome there is an error in console window:
http://MyProject/GlobalAccess/AccessMenu/#Url.Action(%22RoleDropDownChanged%22) 404 (Not Found) jquery-1.7.1.js:8102
Remove this setting:
contentType: 'application/json; charset=utf-8',
You are not sending any JSON to the server.
If you want to keep this setting then make sure that you are sending a valid JSON to your server:
data: JSON.stringify({ 'roleId': '61AD3FD9-C080-4BB1-8012-2A25309B0AAF' })
So:
$.ajax({
url: '#Url.Action("RoleDropDownChanged")',
type: 'POST',
data: { 'roleId': '61AD3FD9-C080-4BB1-8012-2A25309B0AAF' },
success: SuccessRoleChangeHandler,
error: OnFailRoleChangeHandler
});
should work (at least it does for me) with the following action:
[HttpPost]
public ActionResult RoleDropDownChanged(Guid roleId)
{
var actions = Enumerable.Range(1, 10).Select(x => x.ToString()).ToList();
return Json(actions);
}
UPDATE:
According to your comments it looks like you are trying to use server side helpers in a separate javascript which is not possible. Here's what I would suggest you. Start by providing the url when generating your dropdown:
<div class="RoleAccess">
#Html.DropDownListFor(
x => x.RoleDropDown,
Model.Roles,
"-- Select role --",
new {
data_url = Url.Action("RoleDropDownChanged")
}
)
</div>
and then in your separate javascript file:
$(document).ready(function() {
$('div.RoleAccess select').change(function () {
var url = $(this).data('url');
$.ajax({
url: url,
type: 'POST',
data: { 'roleId': '61AD3FD9-C080-4BB1-8012-2A25309B0AAF' },
success: function(result) {
alert('success');
},
error: function() {
alert('error');
}
});
});
});
and then of course you could replace the hardcoded roleId with the currently selected value:
data: { 'roleId': $(this).val() }
Move your $(document).ready function to your View like this:
<script type="text/javascript">
$(document).ready(function () {
//Handle Checks of Actions by RoleName Changed
$('div.RoleAccess select').change(function () {
RoleChangeHandler('#Url.Action("RoleDropDownChanged")');
});
});
</script>
Then in your JS file add url parameter to your function and change ajax call:
function RoleChangeHandler(pageUrl) {
$.ajax({
url: pageUrl,
type: 'POST',
data: { 'roleId': '61AD3FD9-C080-4BB1-8012-2A25309B0AAF' },
dataType: 'json',
processData: false,
contentType: 'application/json; charset=utf-8',
success: function (data) { SuccessRoleChangeHandler(data); },
error: OnFailRoleChangeHandler
});
return false;
}
This should work as you expected.
If your script resides in a .JS file then this is not going to work as it'll be treated as plain text. You can either move entire script to the view or you can re-factor script so that majority of the script remains in the .JS and you then pass relevant values from the view.

asp.net mvc ajax driving me mad

how come when I send ajax request like this everything works
$(".btnDeleteSong").click(function () {
var songId = $(this).attr('name');
$.ajax({
type: 'POST',
url: "/Home/DeleteSong/",
data: { id: songId },
success: ShowMsg("Song deleted successfully"),
error: ShowMsg("There was an error therefore song could not be deleted, please try again"),
dataType: "json"
});
});
But when I add the anonymous function to the success It always showes me the error message although the song is still deleted
$(".btnDeleteSong").click(function () {
var songId = $(this).attr('name');
$.ajax({
type: 'POST',
url: "/Home/DeleteSong/",
data: { id: songId },
success: function () { ShowMsg("Song deleted successfully"); },
error: function () {
ShowMsg("There was an error therefore song could not be deleted, please try again");
},
dataType: "json"
});
});
what if i wanted few things on success of the ajax call, I need to be able to use the anonymous function and I know that's how it should be done, but what am I doing wrong?
I want the success message to show not the error one.
function ShowMsg(parameter) {
$("#msg").find("span").replaceWith(parameter);
$("#msg").css("display", "inline");
$("#msg").fadeOut(2000);
return false;
}
Make sure your action is returning Json data.
"json": Evaluates the response as JSON and returns a JavaScript object. In jQuery 1.4 the JSON data is parsed in a strict manner; any malformed JSON is rejected and a parse error is thrown. (See json.org for more information on proper JSON formatting.)
http://api.jquery.com/jQuery.ajax/
Your action method should surely return Json data. I have the similar code see if that helps.
public ActionResult GetAllByFilter(Student student)
{
return Json(new { data = this.RenderPartialViewToString("PartialStudentList", _studentViewModel.GetBySearchFilter(student).ToList()) });
}
$("#btnSearch").live('click',function () {
var student = {
Name: $("#txtSearchByName").val(),
CourseID: $("#txtSearchByCourseID").val()
};
$.ajax({
url: '/StudentRep/GetAllByFilter',
type: "POST",
data: JSON.stringify(student),
dataType: "json",
contentType: "application/json; charset=utf-8",
success: function(result) {
$("#dialog-modal").dialog("close");
RefreshPartialView(result.data);
}
, error: function() { alert('some error occured!!'); }
});
});
Above code is used to reload a partial view. in your case it should be straight forward.
Thanks,
Praveen
