Incrementing page number with JavaScript

I tried to figure out why the following code doesn't increment the page number, excepting from 1 to 2, but I couldn't find out.
<script>
var n = 1;
function increment() {
return ++n;
}
function countDown(secs,elem) {
var element = document.getElementById(elem);
element.innerHTML = "Timp rămas: "+secs+" secunde.";
if(secs < 1) {
clearTimeout(timer);
window.location.replace('question.php?n='+increment(n));
element.innerHTML += 'Click here now';
}
secs--;
var timer = setTimeout('countDown('+secs+',"'+elem+'")',1000);
}
</script>
Ideas?

Try this:
var params = new URL(document.location).searchParams;
var n = params ? params.get('n') || 1 : 1;
So n is read from URL and not set to 1 everytime a page is loaded.
Edit: ah, and maybe:
var timer = setTimeout(function(){countDown(secs, elem);},1000);

else statement not getting executed?

I want to reload my page if the page is not fully loaded. I am using the below if-else loop. If part is working properly but the else part is not getting executed. I have no idea why is this happening???
Can someone help me to overcome this problem??
function loadCensusData(obj) {
console.log(objXHR1.responseXML);
var vals = objXHR1.responseXML.getElementsByTagName("val");
var noOfCols = 4;
var noOfRows = vals.length / noOfCols;
var row = 0;
while (row < noOfRows) {
var Did = vals[row * noOfCols + 0].childNodes[0].nodeValue;
var DRevenue = vals[row * noOfCols + 2].childNodes[0].nodeValue;
var censusVariable = DRevenue;
var div = Did;
console.log(div);
//console.log(censusVariable);
if (censusVariable < censusMin) {
censusMin = censusVariable;
}
if (censusVariable > censusMax) {
censusMax = censusVariable;
}
map.data.getFeatureById(div).setProperty('census_variable', censusVariable);
document.getElementById('census-min').textContent = censusMin.toLocaleString();
document.getElementById('census-max').textContent = censusMax.toLocaleString();
row++;
}
if (document.readyState == 'interactive' || document.readyState == 'complete') {
alert('Done');
} else {
alert('zzzzzzzzzzzzzzzzzz');
self.location.reload();
}
}
loadCensusData loads the data from my report.
census_variable is used to apply color style
I have used the ready state conditions.
Can someone help me to overcome this problem??

How to force loop to wait until user press submit button?

I have simple function which checks if entered pin code is valid. But i don't know how to force for-loop to wait until i enter code again to check again it's validity.
So how it should be - i type PIN code, then click OK button and it checks whether it's correct (if it is, i can see my account menu; if it's not i have to type it again and i have 2 chances left). My code fails, because PIN when code is wrong program should wait until i type new code and press OK button again.
I tried setTimeout(), callback(), but it doesn't work. This is what i have - a function with for-loop that just runs 3 times (as it is suppose to, but not instantly) without giving a chance to correct the PIN code.
That's whole, unfinished yet, code: http://jsfiddle.net/j1yz0zuj/
Only function with for-loop, which checks validity of PIN code:
var submitKey = function(callback)
{
console.log("digit status" + digitStatus);
if (digitStatus == 0)
{
correctPIN = 1234;
var onScreen = document.getElementById("screen");
for (i=0; i<3; i++)
{
if (onScreen.innerHTML.slice(15, onScreen.innerHTML.length) == correctPIN)
{
setTimeout(accountMenu, 1250);
//break;
}
else
{
onScreen.innerHTML += "<br> Błędny kod PIN! Wpisz PIN ponownie. <br> Pozostało prób: " + (2-i);
callback();
//cardInserted = function(function(){console.log("Ponowne wpisanie PINu");});
}
if (i=2) console.log("blokada");
}
}
else if (digitStatus == 1)
{
}
}

Your approach is wrong. You should not make the user wait!!! You need 2 more variables at the top of your programm pincount=0 and pininputallowed. Increase pincount in the submit key function by 1 and then check if pincount<3.
Here is a corrected version of your code.
http://jsfiddle.net/kvsx0kkx/16/
var pinCount=0,
pinAllowed=true;
var submitKey = function()
{
console.log("digit status" + digitStatus);
if (digitStatus == 0)
{
correctPIN = 1234;
var onScreen = document.getElementById("screen");
pinCount++;
if(pinCount >= 3) {
pinAllowed = false;
onScreen.innerHTML = "<br>blokada";
}
if(pinAllowed){
if (onScreen.innerHTML.slice(15, onScreen.innerHTML.length) == correctPIN)
{
setTimeout(accountMenu, 1250);
//break;
}
else
{
onScreen.innerHTML += "<br> Błędny kod PIN! Wpisz PIN ponownie. <br> Pozostało prób: " + (3-pinCount);
inputLength = 0;
document.getElementById("screen").innerHTML += "<br>Wpisz kod PIN: ";
//callback();
//cardInserted = function(function(){console.log("Ponowne wpisanie PINu");});
}
}
}
else if (digitStatus == 1)
{
}
}
You need to create much more variables to control your machine. Your add/delete digit function had conditions that were badly written and only worked if the text on the screen was short enough.
var inputLength = 0;
addDigit = function(digit){
//numKeyValue = numKeyValue instanceof MouseEvent ? this.value : numKeyValue;{
if (inputLength < pinLength) {
onScreen.innerHTML += this.value;
inputLength++;
}
//if (onScreen.innerHTML == 1234) console.log("PIN został wprowadzony");
},
delDigit = function(){
if (inputLength >= 0) {
onScreen.innerHTML = onScreen.innerHTML.slice(0, -1);
inputLength--;
}
};
If you want to empty the screen at any moment you can insert onScreen.innerHTML = ''; anywhere
ps: Thanks for the exercise and nice automat you made there.

.each function () for cloned inputs

Trying to create the Preview form and do not understand why each function () not working in this script. Or works but only for the last cloned row and ignore the zero values ​​in the previously cloned inputs.
$('input[id^=Mult_factor_]').each(function () {
var MultFactor = $(this).val();
var TotPoints = $('#Tot_points').val();
var exp1 = "Overload";
var exp2 = "Load is: ";
if (MultFactor < 1 || TotPoints > 100) {
$('#ExemptionLimitsText').text(exp1).show();
$('#PrwTotPointsText').hide();
} else {
$('#ExemptionLimitsText').text(exp2).show();
$('#PrwTotPointsText').text($('#Tot_points').val()).show();
}
});
JSfiddle
I need: If at least one of cloned MultiFactor value is zero show "Overload"

Based on your comment, you want to display the word "Overload" if either the "Additional" field is over 100 or if any of the multifactor fields is 0.
However, your loop continues to process if either of these conditions are met.
Do not use a loop, instead search specifically for a multifaktor value of 0.
var totalPoints = parseInt($('#Tot_points').val());
if(totalPoints > 100 || $('input[name="MultFaktor"]').filter(function(){return this.value=='0'}).length > 0) {
$('#ExemptionLimitsText').text("Overload").show();
$('#PrwTotPointsText').hide();
} else {
$('#ExemptionLimitsText').text("Load is: ").show();
$('#PrwTotPointsText').text(totalPoints).show();
}

Return false on overload
var valid = true;
var exp1 = "Overload";
var exp2 = "Load is: ";
var TotPoints = $('#Tot_points').val();
$('input[name=MultFaktor]').each(function () {
var $this = $(this);
if ($.trim($(this).val()) == '0' || TotPoints > 100) {
valid = false;
} else {
$('#ExemptionLimitsText').text(exp2).show();
$('#PrwTotPointsText').text($('#Tot_points').val()).show();
}
});
if (valid == false) {
e.preventDefault();
$('#ExemptionLimitsText').text(exp1).show();
$('#PrwTotPointsText').hide();
}

setInterval won't get out of loop

The following javascript code takes randomly selected value from a array and types it in the input box. I've used jquery. I want to end setInterval "zaman2", so after It ends I can retype the next random string to the input box. But the loop doesn't end and gets stuck. How can I solve this?
Link to jsFiddle: http://jsfiddle.net/AQbq4/4/
var dersler = [...very long list...];
var zaman = setTimeout(function() {
var yeniDers = dersler[Math.floor(Math.random()*dersler.length)];
sayac = 0;
var zaman2 = setInterval(function() {
var harf = yeniDers.slice(0,(sayac+1));
sayac++;
$('#main-search').attr('placeholder', harf).typeahead({source: dersler});
if (sayac == yeniDers.length) {
clearInterval(zaman2);
}
},450);
},2000);

Don't you mean
DEMO
var tId, tId2;
function show() {
var ran = arr[Math.floor(Math.random()*arr.length)];
cnt = 0;
tId = setInterval(function() {
var char = ran.slice(0,(cnt+1));
cnt++;
$( '#main-search' ).attr('placeholder', char);
if (cnt == ran.length) {
clearInterval(tId);
tId2=setTimeout(show,2000);
}
},450);
}
show();
