function not run again if status === false

iam trying to run my function again if the status of my json false but its not working
$(document).ready(function(){
function checkIfCompleted(){
$('.btn').click( function(e) {
e.preventDefault();
var url = "https://localhost/check/1";
$.ajax({
url: url,
success: function(response) {
if(response.status === false){
checkIfCompleted();
}else{
alert(done);
}
},
});
});
}
checkIfCompleted();
});

You are adding click multiple times to the button, you are not rerunning the Ajax call
$(document).ready(function() {
function checkIfCompleted(cnt) {
var url = "https://localhost/check/1";
$.ajax({
url: url,
success: function(response) {
if (response.status === false) {
if (cnt >= 5) {
throw new Error('too many retries');
} else {
checkIfCompleted(++cnt);
}
} else {
alert(done);
}
},
});
}
$('.btn').click(function(e) {
e.preventDefault();
checkIfCompleted(0);
});
});

When I edited directly in the grid instead of the modal at the right the filter never drops but when I edit in modal and save the filter dropped

How can I console "Sucess" present on $.ajax?

How can I show "success" up on Console screen? In a nutshell, I want to show on Console the erros that I forced to happen in a register formulary.
function getRoot() {
var root = "http://" + document.location.hostname + "/login_AMUBA/";
return root;
}
$("#formCadastro").on("submit", function (event) {
event.preventDefault();
var dados = $(this).serialize();
function response() {
return $.ajax({
url: getRoot() + 'controllers/controllerCadastro',
type: 'post',
dataType: 'json',
data: dados,
success: function (response) {
console.log(response);
}
});
}
if (response) {
console.log(success);<--Here
}
});
Finally, the final function (on a php file) should show the error(errors) on console screen, but only "else" works (when it is not commented)
public function validateFinalCad($arrVar)
{
if (count($this->getErro()) > 0) {
$arrResponse = [
"retorno" => "erro",
"erros" => $this->getErro()
];
} else {
/*$this->cadastro->insertCad($arrVar);*/
}
return json_encode($arrResponse);
}

How to wait untill for (append) finished and then show result javascirpt / jquery

I have a function that renders 5 images, and pagination. This function used ajax for getting data.
It works well, but when I using the pagination, I can see the process of 'creating' HTML.
I want to add a loading.gif, until all the HTML finished loading, and show all the results
function getImages(init, buttonPaging) {
var data = {};
if (init) {
data["int"] = "1";
} else {
data["int"] = $(buttonPaging).text();
}
$.ajax({
type: "POST",
url: '#Url.Action("GetImages", "Image")',
data: JSON.stringify(data),
beforeSend: function (xhr) {
xhr.setRequestHeader("XSRF-TOKEN", $('input:hidden[name="__RequestVerificationToken"]').val());
},
contentType: "application/json",
dataType: "json",
success: function (data) {
if (data.success) {
$('#imgList').children().remove();
for (var i = 0; i < data.imageList.length; i++) {
(function (img) {
$('#imgList').append(drawList(img, data.baseUrl));
})(data.imageList[i]);
}
$('#pagingList').children().remove();
for (var i = 0; i < data.pagingInfo.totalPages; i++) {
(function (paging) {
var isCurrentPage = false,
index = i;
index++;
if (paging.currentPage == index) {
isCurrentPage = true;
}
$('#pagingList').append(drawPaging(index, isCurrentPage));
})(data.pagingInfo);
}
} else {
errors += data.error;
}
},
error: function () {
errors += 'Please contact with administrator - img list at edit product';
alert(errors);
}
});
}
I saw tutorials about promises and callbacks, but I'm not good at it and I don't know how to rewrite my code for those. Is there another way to solve the issue ?
solution: It may come in handy for other:
function hideLoader() { setTimeout(function () { $('.loader-sm').hide(); }, 750); }
function showLoader() { $('.loader-sm').show(); }
function hideList() { $('#imgList').hide(); }
function showList() { setTimeout(function () { $('#imgList').show(200); }, 750); }
success: function () {
if (data.success) {
//do something
} else {
showList();
hideLoader();
}
},
error: function () {
showList();
hideLoader();
},
complete: function () {
showList();
hideLoader();
}

have a class for show loading image icon and place it in the block itself and hide it once completed. have a look at the below sample. it may helpful to you.
beforeSend: function() {
$('#imgList').addClass('loading');
},
success: function(data) {
$("#imgList").removeClass('loading');
},
error: function(xhr) { // if error occured
$("#imgList").removeClass('loading');
},
complete: function() {
$("#imgList").removeClass('loading');
}
otherwise you can have a loader div block show the block on beforesend() and hide it in success / complete.

You can do like this i am not sure about but it will help you
function getImages(init, buttonPaging) {
var data = {};
if (init) {
data["int"] = "1";
} else {
data["int"] = $(buttonPaging).text();
}
let promise = new Promise(function(resolve, reject) {
//add your code for add loading.gif
$.ajax({
type: "POST",
url: '#Url.Action("GetImages", "Image")',
data: JSON.stringify(data),
beforeSend: function (xhr) { xhr.setRequestHeader("XSRF-TOKEN",
$('input:hidden[name="__RequestVerificationToken"]').val()); },
contentType: "application/json",
dataType: "json",
success: function (data) {
if (data.success) {
$('#imgList').children().remove();
for (var i = 0; i < data.imageList.length; i++) {
(function (img) {
$('#imgList').append(drawList(img, data.baseUrl));
})(data.imageList[i]);
}
$('#pagingList').children().remove();
for (var i = 0; i < data.pagingInfo.totalPages; i++) {
(function (paging) {
var isCurrentPage = false,
index = i;
index++;
if (paging.currentPage == index) { isCurrentPage = true; }
$('#pagingList').append(drawPaging(index, isCurrentPage));
})(data.pagingInfo);
}
resolve();
} else {
errors += data.error;
resolve();
}
},
error: function () {
errors += 'Please contact with administrator - img list at edit product';
alert(errors);
resolve();
}
});
}
promise.then(
result => alert("done"), // remove loading.gif
);
}

Ajax callback is firing after function call

Hi Have a ajax call in a function thats called on date input change event to check if a date is already in use for User. the success in the Ajax call fires after the click function is finished.
How do I get the success results and continue on with the #datepicker change funtion as I need the json results for rest of function.
controller
public ActionResult IsDateAvailable(DateTime date, int Id) {
var dateAvailable = !(_context.Trading.Any(t => t.uId == Id && t.TradingDate == date));
if (!(dateAvailable)) {
return Json(new {
status = false, msg = "This date already exists."
});
}
return Json(new {
status = true
});
}
JavaScript
$(document).ready(function() {
var message;
var isDateValid;
function CheckDate(para) {
var dateValid;
var mesg;
return $.ajax({
url: '#Url.Action("IsDateAvailable", "Trading")',
type: "GET",
data: para,
dataType: "json",
success: function(data) {
if (!(data.status)) {
message = data.msg;
} else {
isDateValid = true;
}
},
error: function(xhr, httpStatusMessage) {
alert(xhr + httpStatusMessage);
}
});
}
$("#datePicker").change(function() {
$("#alert").css({
'display': 'none'
});
if (Id == 0) {
$("#alert").attr('class', 'alert alert-danger');
$("#alert").text('Please select a User.');
$("#alert").show();
return false;
}
var date = $(this).val();
var para = {
date: date,
Id: Id
};
CheckDate(para);
if (isDateValid) {
$("#btnAdd").show();
} else {
$("#btnAdd").css({
'display': 'none'
});
$("#alert").attr('class', 'alert alert-danger');
$("#alert").text(message);
$("#alert").show();
}
});
});

You should turn to being asynchronous. change your code to match with these:
.
.
.
function CheckDate(para) {
return new Promise((resolve, reject) => {
return $.ajax({
url: '#Url.Action("IsDateAvailable", "Trading")',
type: "GET",
data: para,
dataType: "json",
success: function(data) {
if (!(data.status)) {
message = data.msg;
} else {
isDateValid = true;
}
resolve();
},
error: function(xhr, httpStatusMessage) {
alert(xhr + httpStatusMessage);
reject();
}
});
}
.
.
.
checkDate(para).then(res => {
if (isDateValid) {
$("#btnAdd").show();
} else {
$("#btnAdd").css({
'display': 'none'
});
$("#alert").attr('class', 'alert alert-danger');
$("#alert").text(message);
$("#alert").show();
}
}).catch(err => { /* do something */ });

You just need to set async: false inside your ajax request. You can also remove the word return from the CheckDate, because of it's redundant:
function CheckDate(para) {
var dateValid;
var mesg;
$.ajax({
url: '#Url.Action("IsDateAvailable", "Trading")',
async: false,
type: "GET",
data: para,
dataType: "json",
success: function(data) {
if (!(data.status)) {
message = data.msg;
} else {
isDateValid = true;
}
},
error: function(xhr, httpStatusMessage) {
alert(xhr + httpStatusMessage);
}
});
}
