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',

Lately I've been trying to solve an issue with no luck, basically I'm trying to submit a form to the server using AJAX, the form has files, so I'm using the FormData javascript object in JQuery 1.12. The data arrives to the server but in I way I don't know how to format it.
This is my AJAX function:
function saveMenu(id){
var formElement = document.getElementById("menu-form");
var formData = new FormData(formElement);
formData.append('_method', 'PUT');
$( "#form-wrapper" ).toggleClass( "be-loading-active" );
$.ajax({
type: 'PUT',
headers: {
'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
},
url: "{{url('myUrl')}}",
data: formData,
enctype: 'multipart/form-data',
processData: false,
success: function(response) {
toastr.success('Yai! Saved successfully!')
},
error: function(response) {
toastr.error('Oh oh! Something went really wrong!')
},
complete: function() {
$( "#form-wrapper" ).toggleClass( "be-loading-active" )
}
});
}
and when I perform a dd($request->all()); in my controller I get something like this:
array:1 [
"------WebKitFormBoundaryRCIAg1VylATQGx46\r\nContent-Disposition:_form-data;_name" => """
"_token"\r\n
\r\n
jtv4bnn8WQnP3eqmKZV3xWka2YOpnNc1pgrIfk0D\r\n
------WebKitFormBoundaryRCIAg1VylATQGx46\r\n
Content-Disposition: form-data; name="blocks[43][title]"\r\n
\r\n
...
Things I've tried:
Set the HTTP verb to POST. Same result.
Set the AJAX contentType: false, contentType: application/json. Empty response.
Remove enctype: 'multipart/form-data'. Same response.
Any help is appreciated.
This fixed it for me
data: form_data,
contentType: false,
processData: false,
processData: false prevents jQuery from parsing the data and throwing an Illegal Invocation error. JQuery does this when it encounters a file in the form and can not convert it to string (serialize it).
contentType: false prevents ajax sending the content type header. The content type header make Laravel handel the FormData Object as some serialized string.
setting both to false made it work for me.
I hope this helps.
$('#my-form').submit(function(e) {
e.preventDefault();
var api_token = $('meta[name="api-token"]').attr('content');
form_data = new FormData(this);
$.ajax({
type: 'POST',
url: '/api/v1/item/add',
headers: {
Authorization: 'Bearer ' + api_token
},
data: form_data,
contentType: false,
processData: false,
success: function(result,status,xhr) {
console.log(result);
},
error: function(xhr, status, error) {
console.log(xhr.responseText);
}
});
});
also remember to use $request->all(); $request->input() excludes the files
I've been trying to debug that for 2 hours and i found out that method PUT is not working with formData properly.
Try changing
type : "PUT"
into
method : "POST"
Then change your method on your backend from put to post and you'll see the difference.
I used below codes to test it
$("#menu-form").submit(function (){
var fd = new FormData();
fd.append('section', 'general');
fd.append('action', 'previewImg');
fd.append('new_image', $('.new_image')[0].files[0]);
$.ajax({
method : 'POST',
headers: {
'X-CSRF-TOKEN': '{{ csrf_token()}}'
},
url: "{{url('upload-now')}}",
data : fd,
contentType: false,
processData: false,
success: function(response) {
console.log(response);
},
});
return false;
});
And in my controller
public function test(Request $request){
dd($request->all());
}
Ill try to research more about this issue.
Laravel 7,
if use method PUT in ajax, you can follow
1. change method method: 'PUT' to method: 'POST'
2. add formdata.append with _method PUT like this example :
$('#updateBtn').click(function(e){
e.preventDefault();
var frm = $('#tambahForm');
frm.trigger("reset");
$('.edit_errorNama_kategori').hide();
$('.edit_errorGambar').hide();
var url = "/pengurus/category/"+$('#edit_id').val();
var formdata = new FormData($("#editForm")[0]);
formdata.append('_method', 'PUT'); //*** here
$.ajax({
method :'POST', //*** here
url : url,
data : formdata,
dataType : 'json',
processData: false,
contentType: false,
success:function(data){
if (data.errors) {
if (data.errors.nama_kategori) {
$('.edit_errorNama_kategori').show();
$('.edit_errorNama_kategori').text(data.errors.nama_kategori);
}
if (data.errors.gambar){
$('.edit_errorGambar').show();
$('.edit_errorGambar').text(data.errors.gambar);
}
}else {
frm.trigger('reset');
$('#editModal').modal('hide');
swal('Success!','Data Updated Successfully','success');
table.ajax.reload(null,false);
}
},
error: function (jqXHR, textStatus, errorThrown) {
alert('Please Reload to read Ajax');
console.log("ERROR : ", e);
}
});
});
its works for me
Finally I gave up trying to make it work and tried a more vanilla approach, I still don't know the reason why the request is formated like that, but the XMLHttpRequest() function works perfectly and the migration is not a big deal.
The equivalent of the function I posted about would be:
function saveMenu(action){
var formElement = document.getElementById("menu-form");
var formData = new FormData(formElement);
formData.append('_token', $('meta[name="csrf-token"]').attr('content'));
var request = new XMLHttpRequest();
request.open("POST", "{{url('myUrl')}}");
request.send(formData);
request.onload = function(oEvent) {
if (request.status == 200) {
toastr.success('Yai! Saved successfully!');
} else {
toastr.error('Oh oh! Something went really wrong!');
}
$( "#form-wrapper" ).toggleClass( "be-loading-active" );
};
}
Bit late, but;
This will solve your problem;
var formData = new FormData(document.getElementById('form'));
console.log(...formData);
var object = {};
formData.forEach(function (value, key) {
object[key] = value;
});
Then you can send this object to the server. This is much more readable and works great.
OR
You can simply send this directly;
JSON.stringify(Object.fromEntries(formData));
This is the newer approach.
And don't give up :-)
I have a function called getStudentData(),returns resolved data.
Inside getStudentData(), I have an Ajax request.
I want to Bypass Ajax request in my unit test case using Mocha , so that when i make a call to getStudentData(), the data should be returned.
Please find the code below:
getStudentData: function() {
return studentData || (studentData = new Promise(function(resolve, reject) {
var request = {
//request data goes here
};
var url = "/student";
$.ajax({
url: url,
type: "POST",
data: JSON.stringify(request),
dataType: "json",
contentType: "application/json",
success: function(response, status, transport) {
//success data goes here
},
error: function(status, textStatus, errorThrown) {
reject(status);
}
});
}).then(function(data) {
return data;
})['catch'](function(error) {
throw error;
}));
}
Please let me know how to Bypass Ajax request By stubbing data using sinon.js .so that when i make a call to getStudentData() , data should be returned.
First of all doing:
then(function(data){ return data; })
Is a no-op. So is:
catch(function(err){ throw err; });
Now, your code uses the explicit construction anti-pattern which is also a shame, it can be minimized to:
getStudentData: function() {
var request = {
//request data goes here
};
var url = "/student";
return studentData ||
(studentData = Promise.resolve($.ajax({
url: url,
type: "POST",
data: JSON.stringify(request),
dataType: "json",
contentType: "application/json" })));
}
Now, that we're over that, let's talk about how you'd stub it. I'd do:
myObject.getStudentData = function() {
return Promise.resolve({}); // resolve with whatever data you want to test
};
Which would let you write tests that look like:
it("does something with data", function() { // note - no `done`
// note the `return` for promises:
return myObj.getStudentData().then(function(data){
// data available here, no ajax request made
});
});
Although in practice you'll test other objects that call that method and not the method itself.
Edit: could've researched better... reading this post now: How do I return the response from an asynchronous call?
I have an ajax request which returns JSON data. When I watch it in fiddler, it does go out to the service and get the JSON data, but when I try to set a variable to it's response, that variable is "undefined". If I alert in the success method, it alerts, but the variable is still undefined.
I tried changing the function(data) to function(something) incase that had anything to do with it... same story.
var returndata
$.ajax({
type: "GET",
url: "GetSecurables/",
data: { etaNumber: etaNumber },
success: function (data) {
returndata = data; //undefined
alert('haaalp');
}
});
The JSON is like below
[
{
"DelegateSid":null,
"DisplayName":"Tom",
"HasDelegation":true,
"HasEtaManagement":false
},
{
"DelegateSid":null,
"DisplayName":"Tim",
"HasDelegation":true,
"HasEtaManagement":false
},
{
"DelegateSid":null,
"DisplayName":"Jake",
"HasDelegation":true,
"HasEtaManagement":false
},
{
"DelegateSid":null,
"DisplayName":"Ryan",
"HasDelegation":true,
"HasEtaManagement":false
}
]
Try:
var returndata;
$.ajax({
type: "GET",
url: "GetSecurables/",
data: { etaNumber: etaNumber },
success: function (data) {
console.log(data);
returndata = data;
console.log(returndata);
}
});
If the 2 outputs are the same it might be the case that you're trying to access returndata from outside its scope, hence the undefined, or that you're accessing returndata before the Ajax call completes.
I'm trying to make two or more requests all at once if that's even possible? I'm concerned about speed since after the first request is made I want to display that info onto a web page and then do the same for each additional url.
I've been reading about deferred objects and trying some examples, and so far I've tried to do this,
<!DOCTYPE html>

<script src="http://code.jquery.com/jquery-1.6.4.min.js"></script>

}
// Multiple Ajax Requests
$.when( parentId(), itemLink()).done(function(parentId_data, itemLink_data) {
console.log("parentId_data.items[0].title");
});
});
But it doesn't seem like the functions are functioning. I was expecting to be able to put some stuff after the .when() method inside the function to tell my program what to do, but I'm not getting anything displayed??
Thanks for the help!
Part of the problem is that in the done handler for $.when, the arguments that are passed to the callback are the array of arguments for each request, not simply the data that you want to use. You can get around this by using .pipe as in the example below.
Also, don't specify jsonpCallback unless you have a very good reason, most of the time you want to let jQuery manage that internally for you.
Here's a working example tested on JSFiddle
jQuery(function($) {
function parentId() {
return $.ajax({
url: 'https://www.sciencebase.gov/catalog/items?parentId=504108e5e4b07a90c5ec62d4&max=3&offset=0&format=jsonp',
dataType: 'jsonp',
error: function(e) {
console.log(e.message);
}
// We'll use pipe here so that rather than the value being passed to our $.when handler
// is simply our data rather than an array in the form of [ data, statusText, jqXHR ]
}).pipe(function( data, statusText, jqXHR ) {
return data;
});
}
function itemLink() {
return $.ajax({
url: 'https://www.sciencebase.gov/catalog/itemLink/504216b6e4b04b508bfd333b?format=jsonp&max=10',
dataType: 'jsonp',
error: function(e) {
console.log(e.message);
}
}).pipe(function(data) {
return data;
});
}
// Multiple Ajax Requests
$.when( parentId(), itemLink()).done(function(parentId_data, itemLink_data) {
console.log( parentId_data, itemLink_data );
});
});
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.
