Uploading file using AJAX request - ajax

I'm trying to upload a file using AJAX. I tried to do it using formData() object as well. How can I add a file to following Ajax request?
$.ajax({
url: '/api/add_new_pair/',
method: "POST",
type: 'POST',
FILES: {
'image' : file,
},
data: {
'csrfmiddlewaretoken': csrftoken,
'text': text,
},
}).done(function(response){
console.log(response);
}

You can access the multipart(multimedia) data(header along with data in base64 format) in request.FILES and other data in request.POST
var data = new FormData();
data.append('csrfmiddlewaretoken', '{{csrf_token}}');
data.append('image', $('#image-id').files[0]);
$.ajax({
type: "POST",
url: "/save_design/",
contentType: false,
data: data,
async: true,
cache: false,
processData: false,
beforeSend: function() {
},
success: function(t) {
},
complete: function() {
},
error: function(t) {}
}),
}

merge ajaxform with ajax to upload image

I try to create upload photos in my nodejs site.
I used this code to choose file and upload the image:
var fileData = null;
function loadFile() {
var preview = document.querySelector('file');
var file = document.querySelector('input[type=file]').files[0];
var reader = new FileReader();
reader.onloadend = function () {
fileData = file;
}
if (file) {
reader.readAsDataURL(file);
}
}
function uploadFile() {
data = new FormData();
data.append('file', fileData);
$.ajax({
url: "/post_pdf/",
type: "POST",
data: data,
enctype: 'multipart/form-data',
processData: false,
contentType: false,
success: function(data) {
document.getElementById("result").innerHTML = 'Result: Upload successful';
},
error: function(e) {
document.getElementById("result").innerHTML = 'Result: Error occurred: ' + e.message;
}
});
}
With loadfile funcion i choose my image, and with Uploadfile function i upload the image with ajax.
if i use it alone its work perfect and upload the image to the location.
but when i try to add this code to my code, it make alot of errors.
in my code i send to back end all the forms in the pug file:
$('#account-form').ajaxForm({
error : function(e){
if (e.responseText == 'title-empty'){
av.showInvalidTitle();
}
},
success : function(responseText, status, xhr, $form){
if (status == 'success')
{
$('.modal-alert').modal('show');
console.log(responseText)
}}
});
i try to merge the ajaxform with the ajax but when i merege the formdata or i send in ajaxform the data of the file is send error.
how can i merge the codes?
thanks for helping.
Try to submit form it will submit form with your image.
let form = $("#form_id");
$.ajax({
url : $(form).attr("action"),
type: "POST",
dataType: "json",
processData: false,
contentType: false,
cache: false,
data: new FormData(form[0]),
success:function(data){
},
error: function (xhr, status, e) {
}
});
#Yogesh Patel
when i use this code:
$('#account-form-btn2').on('click', function(e) {
let form = $("#account-form");
$.ajax({
url: $(form).attr("action"),
type: "POST",
dataType: "json",
processData: false,
contentType: false,
cache: false,
data: new FormData(form[0]),
error: function (e) {
if (e.responseText == 'title-empty') {
av.showInvalidTitle();
}
},
success: function (responseText, status, xhr, $form) {
if (status == 'success') {
$('.modal-alert').modal('show');
}
}
});
});
for some reason it sends the values to "routes" three times.
and it doesn't catch the erorrs or success.
and it sends me to a white window with the value of the callback.
if needed, i can send the function that gets the values and returns them (app.post).

jsgrid returns blank line after update

After giving an update via ajax in jsgrid the line returns blank
controller: {
loadData: function(filter) {
var data = $.Deferred();
$.ajax({
type: "GET",
contentType: "application/json; charset=utf-8",
url: "/app/Play/",
dataType: "json"
}).done(function(response) {
data.resolve(response);
});
return data.promise();
},
updateItem: function(item) {
return $.ajax({
type: "POST",
url: "/app/Play/change.php",
data: item,
});
},
}
In the return of the url update: /app/Play/change.php
I return the updated record data in a normal json, same as the initial json used in the load
Resolved:
controller: {
loadData: function(filter) {
var data = $.Deferred();
$.ajax({
type: "GET",
contentType: "application/json; charset=utf-8",
url: "/app/Jogos/app/",
data: filter, // <--Insert line, this is a problem
dataType: "json"
}).done(function(response) {
data.resolve(response);
});
return data.promise();
},
updateItem: function(item) {
return $.ajax({
type: "POST",
url: "/app/Jogos/app/change.php",
data: item
});
},
},

Sending url using ajax on codeigniter

I have this Ajax script where I pass a link to the data variable link, but I
get a 412 error.
$(function() {
$(".check-multi").change(function() {
$.ajax({
type: "POST",
url: "<?php echo site_url('adm/updateproperty'); ?>",
async: true,
data: {
link: $(this).data('link')
},
success: function(msg) {
alert('Success');
if (msg != 'success') {
alert('Fail');
}
}
});
});
});
I have tried
link: encodeURI($(this).data('link'))
And
link: encodeURIComponent($(this).data('link'))
as is suggested on other threads but I still get the 412 error message.
Hope this will help you :
you have added newline character to json data that is why you got error
Do like this :
var link = $(this).data('link');
data: {"link" : link},
/*----OR do this -----*/
data: {"link" : $(this).data('link')},
instead of this :
data: {
link: $(this).data('link')
},
Whole code should be like this :
var link = $(this).data('link');
/*console.log(link)*/
$.ajax({
type: "POST",
url: "<?php echo site_url('adm/updateproperty'); ?>",
async: true,
data: {"link" : link },
success: function(msg) {
alert('Success');
if (msg != 'success') {
alert('Fail');
}
}
});
For More :https://developer.mozilla.org/en-US/docs/Web/HTTP/Status/412
Please change your code in data options. Use this way
data: {"id": ID},
i.e. store the value in a variable and send that variable in data option. If we assume
ID=$(this).data('link');`
Then the code will be as follows:
$(function() {
$(".check-multi").change(function() {
$.ajax({
type: "POST",
url: "<?php echo site_url('adm/updateproperty'); ?>",
async: true,
data: {"id":ID},
success: function(msg) {
alert('Success');
if (msg != 'success') {
alert('Fail');
}
}
});
});
});
Please check it.

ASP.NET MVC AJAX POST ValidateAntiForgeryToken

With my code i get a internal Server error:
#using (Html.BeginForm("", "Manage", FormMethod.Post, new { role = "form"}))
{
#Html.AntiForgeryToken()
}
<script>
function Like(id) {
var requestData = {
profileId: id,
__RequestVerificationToken: $('[name=__RequestVerificationToken]').val(),
};
$.ajax({
url: '/Manage/Like',
type: 'POST',
data: JSON.stringify(requestData),
dataType: "json",
contentType: 'application/json; charset=utf-8',
error: function (xhr) { alert('Error: ' + xhr.statusText); },
success: function (result) {},
async: true,
processData: false
});
}
</script>
Controller:
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Like(string profileId)
{ ... }
If i remove [ValidateAntiForgeryToken] everything works fine, but i lose the sercurity. How can i fix the internal server error?
I see in fiddler SyntaxView 2 requests:
/Manage/Like
{"profileId":13,"__RequestVerificationToken":"jH2ofYlcTiHl8lixW_ANEHOg5KgwRh5Xl43lQfGkDFh55jX-x5cmz4RfPtbDfu92oQsTM7zsop83ldfbxMdIIELYZ0kfByFcXjUp-5mwyKZcQzjXP2gy6qW0iQOtLsqaDjFSzoxnyqM2MD42CbItzw2"}
/Manage
__RequestVerificationToken=MNiKOJHZg7BGaTNccOjrR2Obf_nPhKfcwIPZVBUl53G368n5euzB4y1htH47VKg3V3mHfxkjYZDz6iPepQ7jpeXGARtlj6vV74B8zQbp4by9JR4Rcz4sHANm3WHb6WAXaLcsnFvWJth_8c98XKda5w2
Taking this from a sim. question here include antiforgerytoken in ajax post ASP.NET MVC
function Like(id) {
var form = $('form');
var token = $('input[name="__RequestVerificationToken"]', form).val();
$.ajax({
url: '/Manage/Like',
type: 'POST',
data: { __RequestVerificationToken: token, profileID: id },
error: function (xhr) { alert('Error: ' + xhr.statusText); },
success: function (result) {},
async: true,
processData: false
});
}

jquery tooltip Getting undefined value

I am getting value through post method when i am add it into variable it is showing the same value but when i accessing the value from the outside. it showing me undefined.
var Trends =this.$elm.data('title.poshytip');
var value;
var path = window.location.pathname;
var name = path.substring(path.lastIndexOf('/') + 1);
var dataToSend='{ID:"'+Trends+'"}';
$.ajax({
type: "POST",
url: "UnitedStatesTrends.aspx/serverside",
data: dataToSend,
contentType: "application/json; charset=utf-8",
dataType: "json",
async: true,
cache: false,
success: function( data )
{
value = data.d;
},
error: function() {
alert('error');
}
})
//here
alert(value);
// here i am getting value=undefined in alert but my value is 'UnitedStates'
this.$inner.append(
typeof content == 'function' ?
content.call(this.$elm[0], function(newContent) {
self.update(newContent);
}) :
//here i am setting the value to tooltip
content == '[title]' ? value : content
);
Well I think, you are forgetting to put a semicolan ; after this
$.ajax({
type: "POST",
url: "UnitedStatesTrends.aspx/serverside",
data: dataToSend,
contentType: "application/json; charset=utf-8",
dataType: "json",
async: true,
cache: false,
success: function( data )
{
value = data.d;
},
error: function() {
alert('error');
}
});
