function not run again if status === false - javascript

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);
});
});

I have this code and I am woundering how to change it so that it will get the information without you having to use the click function.

$(this).before('<span class="prev-img" alt="Preview" title="Preview">🔍</span>');

Only one alert for multiple execution in Ajax

I am working rails application.i need to get status of the each selected device.I am able to achieve this but after executing i am putting alert "Successfully created execution record".For every mac selection it is showing alert message.I need to give one alert in end of execution.I am calling display_result in call_endpoint method.Since it is an Ajax call,it is giving alert for every execution.i don't how to limit to single alert for this.
function display_result() {
$('#http_status').html("");
$('#http_status').append(result["response"].status);
if (result["response"].status == "404") {
console.log("HTTP 404");
$('#response_div').addClass("bs-callout-warning");
} else if (result["response"].status == "520") {
console.log("HTTP 502");
$('#response_div').addClass("bs-callout-danger");
} else {
console.log("HTTP 200");
$('#response_div').addClass("bs-callout-success");
if (result["response"].status == "200") {
// $('.loader').show();
$('#cover-spin').show();
$.ajax({
method: "GET",
dataType: "text",
url: "create_execution",
data: {
http_status: result["response"].status,
mac_address: mac,
},
success: function (execution_record_id) {
$('#cover-spin').hide();
alert('Successfully created execution record");
}
});
}
function call_endpoint() {
var values = new Array();
webpa = $('#Device-PA').is(":visible");
rpil = $('#Device-SN').is(":visible");
groupselect = $('#Group-Select').is(":visible");
parameter_name = $('#tr_object').val();
if (webpa) {
$.each($("input[name='checkBox[]']:checked").closest("td").next("td"), function () {
values.push($(this).text().trim())
});
m = values.length
} else {
$.each($("input[name='checkBox[]']:checked").closest("td").next("td"), function () {
values.push($(this).text().trim())
});
m = values.length
}
serialnumber = $('#pa_serialnumber').val();
oid = $('#sn_serialnumber').val();
protocol = {
pa: pa,
sn: sn,
}
if (pa) {
for (var i = 0; i < m; i++) {
(function () {
var macAdd = values[i];
$.ajax({
method: "GET",
url: "get_object",
dataType: "json",
data: {
parameter: parameter_name,
mac: macAdd,
protocol: protocol,
serialnumber: serialnumber,
},
success: function (result) {
console.log(result);
NProgress.done();
console.log("result for webpa");
display_result();
},
statusCode: {
404: function () {
console.log("Call failed");
}
}
});
})();
}
}
Below is changed code..
Copy below code as it is.
function display_result(total,current) {
$('#http_status').html("");
$('#http_status').append(result["response"].status);
if (result["response"].status == "404") {
console.log("HTTP 404");
$('#response_div').addClass("bs-callout-warning");
} else if (result["response"].status == "520") {
console.log("HTTP 502");
$('#response_div').addClass("bs-callout-danger");
} else {
console.log("HTTP 200");
$('#response_div').addClass("bs-callout-success");
if (result["response"].status == "200") {
// $('.loader').show();
$('#cover-spin').show();
$.ajax({
method: "GET",
dataType: "text",
url: "create_execution",
data: {
http_status: result["response"].status,
mac_address: mac,
},
success: function (execution_record_id) {
$('#cover-spin').hide();
if(total == current)
{
alert('Successfully created execution record");
}
}
});
}
}
}
function call_endpoint() {
var values = new Array();
webpa = $('#Device-PA').is(":visible");
rpil = $('#Device-SN').is(":visible");
groupselect = $('#Group-Select').is(":visible");
parameter_name = $('#tr_object').val();
if (webpa) {
$.each($("input[name='checkBox[]']:checked").closest("td").next("td"), function () {
values.push($(this).text().trim())
});
m = values.length
} else {
$.each($("input[name='checkBox[]']:checked").closest("td").next("td"), function () {
values.push($(this).text().trim())
});
m = values.length
}
serialnumber = $('#pa_serialnumber').val();
oid = $('#sn_serialnumber').val();
protocol = {
pa: pa,
sn: sn,
}
if (pa) {
for (var i = 1; i <= m; i++) {
(function () {
var macAdd = values[i];
$.ajax({
method: "GET",
url: "get_object",
dataType: "json",
data: {
parameter: parameter_name,
mac: macAdd,
protocol: protocol,
serialnumber: serialnumber,
},
success: function (result) {
console.log(result);
NProgress.done();
console.log("result for webpa");
display_result(m,i);
},
statusCode: {
404: function () {
console.log("Call failed");
}
}
});
})();
}
}
}
result and mac is not defined in display_result function. result appears intended to be the resulting value of jQuery promise object returned from $.ajax(). Am not certain what mac is indented to be.
You can substitute $.when() and $.map() for for loop, return a jQuery promise object from call_endpoint(), include error handling, chain .then() to call_endpoint() call to execute alert() once.
function call_endpoint() {
return $.when.apply($, $.map(values, function(macAdd) {
return $.ajax().then(display_result)
}))
}
callEnpoint()
.then(function() {
alert('Successfully created execution record');
}, function(jqxhr, textStatus, errorThrown) {
console.error(errorThrown)
});
function display_result(reuslt) {
..
if (if (result["response"].status == "200")) {
return $.ajax() // remove `alert()` from `success`
}
return;
}

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);
}
});
}

$.when().done not working on blur event

I am trying to run a validation check and need to call the database and get result before I proceed, I am using ajax promise handler to wait for the response but for some reason it execution flow does not stop.
$("#attr").blur(function() {
var attrValue = $("#attr").val();
if (attr.length > 256) {
$("#Validation").text(" has a max of 256 characters");
$("#Validation").show();
$("#attr").focus();
} else {
if (attrValue.length > 0) {
$.when(check_attribute_name(attrValue)).done(function (data) {
if (data.result == false) {
$("#Validation").text("Another exists with this name. Try again!");
$("#Validation").show();
$("#attr").focus();
$("#unique").val("fasle");
} else {
$("#attrValidation").hide();
}
});
}
}
});
function check_attribute_name(attrValue) {
return $.ajax({
type: "Post",
url: "#Url.Action("Validation", "validator")",
data: { name: attrValue },
});
}
