I have a simple app that start, pauses and reset a timer when the appropriate button is clicked. What I am trying to do is create an alert box when the pause button is clicked and once someone clicks OK on the alert box, the timer starts again. I thought simply mimicking selecting the start button again would do this, but instead it starts the time like the pause never occurred. Any suggestion?

How do I get my timer to stop, when my 10th and last question has been answered?

The goal I am trying to achieve is to get my timer to stop when all the questions of my quiz has been answered. I have 10 total questions. I have been able to get the timer to start. But getting ot to stop on the click of submit on the 10th question is something I can't figure out.
Let me know if you know what I am doing
StackOverflow said my code was too long... I added my code to codepen. I also included my JS on here.
// variables
var score = 0; //set score to 0
var total = 10; //total nmumber of questions
var point = 1; //points per correct answer
var highest = total * point;

Any help would be appreciated.

its a pretty simple solution just call the stop function in the if condition of n == total
if (n == total) {
$('#results').html('<h3>Your score is: ' + score + ' out of ' + highest + '!</h3>
<button onclick="myScore()">Add Your Name To Scoreboard!</a>')
stop()
}

Try using clearInterval() to stop the timer.

How to stop and reset my countdown timer?

I'm trying to make my countdown timer do the following 4 things
When 'start' is clicked, change button to 'stop'
When 'stop' is clicked, stop the timer
When timer is stopped, show 'start' button
When 'reset' is clicked, reset the timer
$(document).ready(function() {
var counter = 0;
var timeleft = 5;
function nf(num) {
var s = '0' + num;
return s.slice(-2);
}
function convertSeconds(s) {
var min = Math.floor(s / 60);
var sec = s % 60;
return nf(min, 2) + ' ' + nf(sec, 2);
}
function setup() {
var timer = document.getElementById("timer");
timer.innerHTML = (convertSeconds(timeleft - counter));
var interval = setInterval(timeIt, 1000);
function timeIt() {
counter++;
timer.innerHTML = (convertSeconds(timeleft - counter));
if (counter == timeleft) {
clearInterval(interval);
}
}
}
$("#timer-button").click(function() {
setup();
});
});

I recently needed something like this too. I ended up writing an ES6 class for that.
In my solution, I used Events to notify other components about the timer. Here is a fiddle in which I met your needs, but I left my EventManager() calls to show what I actually did.
The used EventManager is this one. The timer counts in 100ms steps by default, but you can adjust this by calling startTimer() with the interval of choice.
class Timer {
constructor(maxTime, startValue = 0) {
// Actual timer value 1/10s (100ms)
this.value = startValue;
// Maximum time of the timer in s
this.maxTime = maxTime * 10;
this.timerRunning = false;
}
/**
* Starts the timer. Increments the timer value every 100ms.
* #param {number} interval in ms
*/
startTimer(interval = 100) {
if (!this.timerRunning) {
let parent = this;
this.timerPointer = setInterval(function() {
if (parent.value < parent.maxTime) {
parent.value++;
//EventManager.fire('timerUpdated');
$("span").text(parent.value / 10 + "/" + parent.maxTime / 10);
} else {
parent.stopTimer();
//EventManager.fire('timeExceeded');
$("button").text("Start");
this.resetTimer();
$("span").text("Countdown over");
}
}, interval);
this.timerRunning = true;
}
}
// Stops the Timer.
stopTimer() {
clearInterval(this.timerPointer);
this.timerRunning = false;
}
// Resets the timer and stops it.
resetTimer() {
this.stopTimer();
this.value = 0;
$("span").text("0/" + this.maxTime/10);
//EventManager.fire('timerUpdated');
}
// Resets the timer and starts from the beginning.
restartTimer() {
this.resetTimer();
this.startTimer();
}
}
let timer = new Timer(6);
$("#start-stop").click(function() {
if (timer.timerRunning) {
timer.stopTimer();
$("#start-stop").text("Start");
} else {
timer.startTimer();
$("#start-stop").text("Stop");
}
});
$("#reset").click(function() {
timer.resetTimer();
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<button id="start-stop">
Start
</button>
<button id="reset">
Reset
</button>
<span>Timer: </span>

I want to make countdown then capatcha

Hi
I got countdown code
<script type="text/javascript">
window.onload = function() {
countDown('my_div1', '<form>1+1=<input name="d" type="text" /></form>', 10);
}
function countDown(elID, output, seconds) {
var elem = document.getElementById(elID),
start = new Date().getTime(), end = start+seconds*1000,
timer = setInterval(function() {
var now = new Date().getTime(), timeleft = end-now, timeparts;
if( timeleft < 0) {
elem.innerHTML = output;
clearInterval(timer);
}
else {
timeparts = [Math.floor(timeleft/60000),Math.floor(timeleft/1000)%60];
if( timeparts[1] < 10) timeparts[1] = "0"+timeparts[1];
elem.innerHTML = "Time left: "+timeparts[1];
}
},250);
}
</script>
I want when the countdown end appear CAPTCHA or question if this right, then continue to link

try to put the countdown function here
window.onload = function() {
countDown('my_div1', //here// , 10);
}

Assume that your countdown coding is working fine and you have a div in which captcha is stored say div id = "captchadiv",
<script type="text/javascript">
window.onload = function() {
//////////////////////////////////////////////////////
set the visibility of the captcha hidden here.
//////////////////////////////////////////////////////
countDown('my_div1', '<form>1+1=<input name="d" type="text" /></form>', 10);
}
function countDown(elID, output, seconds) {
var elem = document.getElementById(elID),
start = new Date().getTime(), end = start+seconds*1000,
timer = setInterval(function() {
var now = new Date().getTime(), timeleft = end-now, timeparts;
if( timeleft < 0) {
elem.innerHTML = output;
clearInterval(timer);
//////////////////////////////////////////////////////
set visibility of captchadiv to visibile.
//////////////////////////////////////////////////////
}
else {
timeparts = [Math.floor(timeleft/60000),Math.floor(timeleft/1000)%60];
if( timeparts[1] < 10) timeparts[1] = "0"+timeparts[1];
elem.innerHTML = "Time left: "+timeparts[1];
}
},250);
}
//////////////////////////////////////////////////////
add a function here to validate the captcha.
If validation succeeds, do success action.
If validation fails, set captcha visibility to hidden and again call the counttDown function.
//////////////////////////////////////////////////////

Check this out. (Untested version)

JavaScript countdown timer not starting

I tried using this JavaScript countdown timer on my page but the timer won't start.
What am I doing wrongly?
var CountdownID = null;
var start_msecond = 9;
var start_sec = 120;
window.onload = countDown(start_msecond, start_sec, "timerID");
function countDown(pmsecond, psecond, timerID) {
var msecond = ((pmsecond < 1) ? "" : "") + pmsecond;
var second = ((psecond < 9) ? "0": "") + psecond;
document.getElementById(timerID).innerHTML = second + "." + msecond;
if (pmsecond == 0 && (psecond-1) < 0) { //Recurse timer
clearTimeout(CountdownID);
var command = "countDown("+start_msecond+", "+start_sec+", '"+timerID+"')";
CountdownID = window.setTimeout(command, 100);
alert("Time is Up! Enter your PIN now to subscribe!");
}
else { //Decrease time by one second
--pmsecond;
if (pmsecond == 0) {
pmsecond=start_msecond;
--psecond;
}
if (psecond == 0) {
psecond=start_sec;
}
var command = "countDown("+pmsecond+", "+psecond+", '"+timerID+"')";
CountdownID = window.setTimeout(command, 100);
}
}
<span style="color:red" name="timerID" id="timerID">91.6</span>

here is what you need to do first
window.onload = countDown(start_msecond, start_sec, "timerID");
should be
window.onload = function () {
countDown(start_msecond, start_sec, "timerID");
}
also you should avoid using a string in your setTimeout function:
CountdownID = window.setTimeout(function () {
countDown(pmsecond,psecond,"timerID");
}, 100);
