JavaScript Increment number every time (if statement) is true

In my code I am retrieved data from the data base every 30 seconds using AJAX. I want to use JavaScript to increment variable wht every time data is received from the database (every 30 seconds) and when if statement is true. Below code is working and incrementing to 1 but it doesn't go above 1. Does anyone has a solution for this problem?
<script>
$(document).ready(function () {
ajax_call = function() {
$.ajax({
type: "GET",
url: "test.php",
dataType: "html",
success: function (response) {
color = response;
console.log(color);
if (color == white){
var wht = (function(w) {
return function() {
w += 1;
return w;
}
}(0));
document.getElementById("memo").value = wht();
}else{
console.log("Color is not white");
}
var interval = 30000;
setInterval(ajax_call, interval);
});
</script>
<script>
const minusButtonFw = document.getElementById('memo-minus');
const plusButtonFw = document.getElementById('memo-plus');
var memo = document.getElementById('memo');
minusButtonFw.addEventListener('click', event => {
event.preventDefault();
const currentValue = Number(memo.value);
memo.value = currentValue - 1;
});
plusButtonFw.addEventListener('click', event => {
event.preventDefault();
const currentValue = Number(memo.value);
memo.value = currentValue + 1;
});
</script>

First of all your variable wht is a function. If you simply want to keep track of the number of time the if conditions is true you can do it by making the variable static (literaly). you can achive this by storing the variable in a global scope.
Also there are sytax errors in your code too where wht is defined.
try this
$(function () {
var memo = document.getElementById("memo");
memo.val = 0;
var ajax_call = function () {
$.ajax({
type: "GET",
url: "test.php",
dataType: "html",
success: function (response) {
color = response;
console.log(color);
if (color == white) {
memo.val++;
memo.value = memo.val;
} else {
console.log("Color is not white");
}
}
});
}
var interval = 30000;
setInterval(ajax_call, interval);
});
A Note:
If the response is managed by you, I would recomend sending the response as json rather than simply sending it as an html with just one value color.

You'll need to keep track of "w". Your current setup is using "w" as a parameter to a function. You'd need to keep it outside of the function and increment it from inside the function. You'll also need to wrap that function in an interval Something like the following:
var w = 0;
function setWhite(color) {
if (color == white) {
w++;
document.getElementById("memo").value = w;
} else {
console.log("Color is not white");
}
}
setInterval(function() {
setWhite(color);
}, 30000);
This should give you what you want. I didn't run the code so there are probably syntactical errors that you'll need to correct.

Try change the line
document.getElementById("memo").value = wht();
to
document.getElementById("memo").value = wht(document.getElementById("memo").value);
Your full code:
<script>
$(document).ready(function () {
ajax_call = function() {
$.ajax({
type: "GET",
url: "test.php",
dataType: "html",
success: function (response) {
color = response;
console.log(color);
if (color == white){
var wht = (function(w) {
return function() {
w += 1;
return w;
}
}(0));
document.getElementById("memo").value = wht(document.getElementById("memo").value);
}else{
console.log("Color is not white");
}
var interval = 30000;
setInterval(ajax_call, interval);
});
</script>

I made an example with setInterval. I made w global so it will work. Try this:
var w = 0;
var interval = setInterval(function() {
if (color == white) {
w++;
document.getElementById("memo").value = w;
} else {
console.log("Color is not white");
}
}, 30000);

Javascript Timers assistance

I am having some issues trying to use the console to modify the time remaining on one site.
I want to be able to set the Time remaining to zero to be able to proceed to the next page.
I believe that the issue is that there are multiple things that need to be set in order to proceed to the next page.
See code below, any help you can provide would be appreciated.

I happened to stumble upon the same code. If you were on the same site as me,
I have a potential fix.
Instead of editing the time remaining I setup a script that will click next when the time has expired. I was too lazy to check whether they are checking timestamps server side. Also the server logs will look more similar to a regular user.
Instructions:
Download the following extension for Chrome
https://chrome.google.com/webstore/detail/custom-javascript-for-web/poakhlngfciodnhlhhgnaaelnpjljija?hl=en
Navigate to the site
click the CJS chrome extension button
check "enable cjs for this host"
paste the following JS snippet into the JS box
var t=setInterval(try_hit_next,1000);
function try_hit_next(){
if (estimatedSecondsRemaining <= 0)
window.location = $('#next_top').parent()[0]['href'];
}
click save

1) No needs to assign "setInterval" to a variable t
2) Has somebody tried to make fully automated script for this resource, i mean "driving defensive course" cause it pushes popups with personal questions randomly and besides shows pages with a сourse-related questions (constantly the same), so hope it's gonna be very useful "tool" )

Unfortunately the timers are actually being kept server-side. You can watch a POST to CourseData.aspx and it will return with new values for SecondsRemaining and SecondsElapsed. These new values are used to set the client-side timers. You can change the client side variables all you want but when you move to the next page, another call to CourseData.aspx is done to fetch the server time. So the server's timers rule this entire process.
I believe the only reason you see any JS timers is to provide a (now hidden) simple "time remaining" clock for the user.
However I am willing to bet that there's a way to POST a new time or SecondsRemaining to the CourseData.aspx page, I just don't know what set of post data variables might be needed to do so.

jquery load more onscroll calling the function many times at once

I have written an javascript which load more when user scroll to bottom of a div .
This is the code I'm using :
var loadingSet = 0
var diMore = 1
var ob = 'default';
var db = 'desc' //نزولی
var doAppend = true
var loading= false;
function sort(){
diMore=1
ob = $('#ob').val();
db = $('#db').val();
loadingSet=-1
doAppend = false
loadMore()
}
function loadMore()
{
if (diMore ==1 && !loading){
var loading= false;
loadingSet++ ;
loading=true
$(document).ready(function() {
$(document).on({
ajaxStart: function() { $("#spinner").css("display", "block"); },
ajaxStop: function() { $("#spinner").fadeOut('slow'); }
});
$.ajax({
type: "POST",
url:baseUrl+ "getNewItems.php",
data: "limit=<?php echo $limit?>&stId=<?php echo $admins_id?>&status="+status+"&ob=" + ob +"&da="+ db +"&loadingSet="+loadingSet+"&submit=true",
success: function(msg){
str=$.trim(msg)
var More = str.split('##');
if (More[0] == 'n'){
diMore=0
}else{
$(window).bind('scroll', bindScroll2);
loading=false
}
if (doAppend){
$('#prodDiv').append(More[1])
}else{
doAppend=true
$('#prodDiv').html('')
$('#prodDiv').fadeOut(500, function() {
$(this).html(More[1]).fadeIn(500);
});
}
}
})
})
}
}
function bindScroll2(){
$(window).bind('scroll', function() {
if($(window).scrollTop() >= $('#mainDivCategory').offset().top + $('#mainDivCategory').outerHeight() - window.innerHeight) {
$(window).unbind('scroll');
if (!loading){
loadMore();
}
}
});
}
$(window).scroll(bindScroll2);
The problem is that when I scroll at the bottom of the div , the loadMore function is calling so many time at one . maybe about 50 -60 request at once.
What's the problem ?
Thanks

Jquery ajax is calling multiple time on scroll

Here in the below code iam calling ajax on scroll.
But this is calling ajax multiple times. To restrict this i added setTimeout function and flag (i.e. isActive) still it is calling two times.
Please help me where iam going wrong.
Thanks in advance
var isActive = false;
var sIndex =12;
var myflag = '1';
var offSet = 12;
var timeout;
jQuery(window).scroll(function () {
if(typeof timeout == "number") {
window.clearTimeout(timeout);
delete timeout;
}
timeout = window.setTimeout( check, 500);
});
function check(){
var cat = $(".mi-selected").attr('id');
var tecID = $("#technologyID").val();
var notSameInd = $("#notSameInd").val();
var sIndex =$("#startInd").val();
if (!isActive && ($(window).scrollTop() + $(window).height() == $(document).height()) && (sIndex !== notSameInd) ) {
var isActive = true;
jQuery.ajax({
type: "POST",
url: 'http://some.com/responcePortfolio.php',
data: {
tecID:tecID,
cat:cat,
startIndex:sIndex,
offset:offSet,
count_now:count_now
},
success: function (result) {
if(result !== ''){
jQuery("#LoaderImage").hide();
jQuery("#portfolioList").append(result);
$("#notSameInd").val(sIndex);
sIndex = parseInt(sIndex) + parseInt(offSet);
$("#startInd").val(sIndex);
}
else{
jQuery("#LoaderImage").hide();
}
isActive = false;
},
error: function (error) {
//alert(error);
}
});
}
}

can anybody help me how to deal this 2 javascript conflict

This is the error I received
TypeError: Result of expression '$('.navigation')' [null] is not an object. Can anybody please explain to me why this error occur?

You receive this error because if the following function in the first code:
function $(id) {
return document.getElementById(id);
}
This overlaps with jQuery's $ function which is required by the second piece of code. rewrite the first piece of code to use jQuery's $() function or rename $() in the first piece of code and find/replace.

Do you have html elements with the class name "navigation" in your code?
