I have a problem with my dropzone,
$(".js-example-basic-multiple").select2();
Dropzone.options.dropZone = {
//options here
maxFilesize: 2,
addRemoveLinks: true,
removedfile: function(file) {
var name = file.name;
$.ajax({
type: 'POST',
url: host+'upload/unfile',
data: "id="+name,
dataType: 'html'
});
var _ref;
return (_ref = file.previewElement) != null ? _ref.parentNode.removeChild(file.previewElement) : void 0;
//console.log();
},
init: function() {
this.on("maxfilesexceeded", function(file){
alert("No more files please!");
});
}
}
My problem is, when a file fails to upload, it still shows the preview images, so i need that file to be removed automatically when these file fails to upload, how can I do that??
I think, if I understand you correctly, you can just delete the image with this code:
Dropzone.options.dropZone = {
...
, error: function(file, message, xhr) {
$(file.previewElement).remove();
},
...
}
Just read the documentation again.
This code is from the docs:
myDropzone.on("error", function(file) {
myDropzone.removeFile(file);
});
Please let me know, if it works in your case.
When connect error is "xhr.ontimeout", function "error:" don't run.
I need (paste next to "init:"):
sending: function(file, xhr, formData) {
//Execute on case of timeout only
xhr.ontimeout = function(e) {
alert('connection interrupted');
};
}

Good day, I am trying to manual ajax this
Add to cart
What this does is, It will add to the cart the one-time purchase option from the woocommerce subscription. I am trying to ajax it so it won't refresh the page when you click on it.
I found an idea how to manually ajax it by using these lines of codes. Reference here
(function($) {
$(document).on('click', '.testing', function(e) {
var $thisbutton = $(this);
try {
var href = $thisbutton.prop('href').split('?')[1];
if (href.indexOf('add-to-cart') === -1) return;
} catch (err) {
return;
}
e.preventDefault();
var product_id = href.split('=')[1];
var data = {
product_id: product_id
};
$(document.body).trigger('adding_to_cart', [$thisbutton, data]);
$.ajax({
type: 'post',
url: wc_add_to_cart_params.wc_ajax_url.replace(
'%%endpoint%%',
'add_to_cart'
),
data: data,
beforeSend: function(response) {
$thisbutton.removeClass('added').addClass('loading');
},
complete: function(response) {
$thisbutton.addClass('added').removeClass('loading');
},
success: function(response) {
if (response.error & response.product_url) {
window.location = response.product_url;
return;
} else {
$(document.body).trigger('added_to_cart', [
response.fragments,
response.cart_hash
]);
$('a[data-notification-link="cart-overview"]').click();
}
}
});
return false;
});
})(jQuery);
The codes above work and it does ajax however, it displays the monthly subscription, not the one-time purchase. It should display the one-time purchase because of the &convert_to_sub_55337=0 which means the one-time subscription option is selected.
Also, I am getting an error after clicking the button on the console log
Uncaught TypeError: $button is undefined
I am a newbie to handling ajax so I am unsure about the issue
Thank you in advance!!
you can try this code i hope it will helped.
(function($) {
$(document).on('click', '.testing', function(e) {
var $thisbutton = $(this);
try {
var href = $thisbutton.prop('href').split('?')[1];
if (href.indexOf('add-to-cart') === -1) return;
} catch (err) {
return;
}
e.preventDefault();
var product_id = href.split('=')[1];
var data = {
product_id: product_id
};
$(document.body).trigger('adding_to_cart', [$thisbutton, data]);
$.ajax({
type: 'post',
url: wc_add_to_cart_params.wc_ajax_url.replace(
'%%endpoint%%',
'add_to_cart'
),
data: data,
beforeSend: function(response) {
jQuery('.testing').removeClass('added').addClass('loading');
},
complete: function(response) {
jQuery('.testing').addClass('added').removeClass('loading');
},
success: function(response) {
if (response.error & response.product_url) {
window.location = response.product_url;
return;
} else {
$(document.body).trigger('added_to_cart', [
response.fragments,
response.cart_hash
]);
$('a[data-notification-link="cart-overview"]').click();
}
}
});
return false;
});
})(jQuery);
I am performing an Ajax (JQuery) request on a php script which iterates. At each iteration I do an "echo" of the value of the loop counter, encoded in JSon. The goal is to manage the display of a progress bar.
By doing this I hoped to intercept and retrieve each of the counter values in a separate response thanks to the "progress" event.
Actually I only have one answer which contains all the counter values.
My research always leads me to information about downloading files, which is not my situation.
Maybe I should use the "onreadystatechange" event, but I don't see how to fit it into my code: $ Ajax parameter or separate function?
If anyone has an idea to solve my problem.
Here is my JS code
function DiffuseOffre(envoi, tab, paquet, dest) {
//$('#cover-spin').show(0);
$("#xhr-rep").css("display", "block");
var server = '/Admin/Offres/DiffuseOffre.php';
$.ajax({
url: server,
type: 'Post',
dataType: 'json',
data: {
envoi: envoi,
tab: tab,
paquet: paquet,
dest: dest
},
xhr: function() {
var xhr = new window.XMLHttpRequest();
xhr.addEventListener("progress", function(evt) {
if (evt.lengthComputable) {
var compteur = evt.text;
$("#xhr-rep").html(compteur);
}
}, false);
return xhr;
},
success: function(msg) {
//$('#cover-spin').css("display", "none");
$('#xhr-rep').css("display", "none");
if (msg.hasOwnProperty('erreur')) {
$("#dialog-erreur").html(msg.erreur);
$("#dialog-erreur").dialog("open");
$("#dialog-erreur").dialog({
width: '600px',
title: msg.title
})
} else {
$("#dialog-message").html(msg.message);
$("#dialog-message").dialog("open");
$("#dialog-message").dialog({
width: '600px',
title: msg.title
})
if (paquet == 1) {
$("#envoi_" + dest).remove();
$("#diffuser").remove();
}
if (msg.hasOwnProperty('encours')) {
$("#en_cours").html(msg.encours);
}
if (msg.hasOwnProperty('fieldset')) {
$("#" + msg.fieldset).remove();
}
}
}
})
}
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).
I am tring to download a file, via ajax call.
It should process every 20secs.
If file present it will get downloaded and shall stop the futher ajax call, else same ajax should be processed till file is downloaded.
Below is what i have tried
$.ajax({
url: baseUrl + '/ajax/exportStudentInformation',
data: {
'studentId' : studentId
},
type: "post",
success: function(response) {
setTimeout(function () {
timeIntervalDownLoadFile = downloadFile(studentname);
}, 60000);
},
error: function(){
alert('There was error in processing csv file, please try again');
}
});
This is the function that needs to check if the file is present on the cloud and download it.
downloadFile: function(studentname) {
$.ajax({
url: baseUrl + '/ajax/downloadFile',
data: {
'studentname': studentname
},
'type': 'POST',
error: function(jqXHR, status, error) {
alert('There was error in downloading file, please try again!!!');
},
abort: function(jqXHR, status, error) {
},
beforeSend: function() {
var message = "The file is being downloaded, please wait";
$('#alertBar').html("<div class=\"alert alert-info\" >"+message+"<a class=\"close\">×</a></div>")
$("#alertBar").fadeTo(2000, 500).slideUp(500, function(){
$("#alertBar").slideUp(500);
});
},
success: function(response) {
if (response.status) {
window.location.href = "https://urlwhereFileisStoredOnCloud/"+response.filename;
} else {
var message = "File does not exist, please use export to generate file";
$('#alertBar').html("<div class=\"alert alert-danger\" >"+message+"<a class=\"close\">×</a></div>")
$("#alertBar").fadeTo(2000, 500).slideUp(500, function(){
$("#alertBar").slideUp(500);
});
$("html, body").animate({ scrollTop: $('#alertBar').offset().top }, 1000);
}
},
});
},
I have used set interval of jquery to call the second function time after delay. but it does not stops once the file download popup is shown. Any help will be apprciated.
I know there's other post about this. but there's no answer.
Situation, I have an ajax command. It take time because I have somes things to get.
I want to include a loading between the execution of the ajax.
I want to use jquery BlockUI because its simple and good looking.
But I dont know why the visual effect not working until ajax load the entire data(like when "success" begin).
I try multiple way but not working.
here's my last code :
function from http://www.codeproject.com/Articles/382390/An-Example-to-Use-jQuery-Global-AJAX-Event-Handler
var AjaxGlobalHandler = {
Initiate: function(options) {
$.ajaxSetup({ cache: false });
// Ajax events fire in following order
$(document).ajaxStart(function() {
$.blockUI({
message: options.AjaxWait.AjaxWaitMessage,
css: options.AjaxWait.AjaxWaitMessageCss
});
}).ajaxSend(function(e, xhr, opts) {
}).ajaxError(function(e, xhr, opts) {
if (options.SessionOut.StatusCode == xhr.status) {
document.location.replace(options.SessionOut.RedirectUrl);
return;
}
$.colorbox({ html: options.AjaxErrorMessage });
}).ajaxSuccess(function(e, xhr, opts) {
}).ajaxComplete(function(e, xhr, opts) {
}).ajaxStop(function() {
$.unblockUI();
});
}
};
call ready
var options = {
AjaxWait: {
AjaxWaitMessage: '<h1 class="ui-overlay-loading-content"><img class="ui-overlay-loading-image" src="_inc/img/loading3circle1.gif" />Chargement des données ...</h1>',
AjaxWaitMessageCss: { backgroundColor: '#ffffff' }
},
AjaxErrorMessage: "<h6>Erreur!/h6>"
};
AjaxGlobalHandler.Initiate(options);
call execution
$.ajax({
type: "POST",
url: location.href.split('/').pop() + "?action=" + actionName + "&recherche=" + recherche,
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function(response) {
FillDataGridOnSuccess(response, gridId, dataTypeName);
},
error: function(xhr, ajaxOptions, thrownError) {
alert("xhr.status : " + xhr.status);
alert("thrownError : " + thrownError);
}
});
I try also
var ajaxSettings = function(options) {
return $.extend(
{
beforeSubmit: function() {
//beforeSend: function() {
$.blockUI({ overlayCSS: { backgroundColor: '#ffffff' },
message: '<h1 class="ui-overlay-loading-content"><img class="ui-overlay-loading-image" src="_inc/img/loading3circle1.gif" />Chargement des données ...</h1>'
});
},
complete: function() {
$.unblockUI();
}
},
options
);
};
Every test that I did end with a loading who seems to only appear on ajaxSuccess.
I know there's sample on official blockUI site http://jquery.malsup.com/block/#demos
and they working there, but I cant on my own. did anybody see why?
