Problem: When I click my start button after stopping my timer, I can't seem to get the timer to resume.
Desired result: For any given timer, when I click the start button, after clicking the stop button, I want the time to resume where it left off.
I figured that when clicking the start button, it would just call the setInterval function again after being cleared, however, I am having issues figuring that out.
I have the stop event in each function in the same scope as the intervalID var's, which hold the setInterval functions itself. Which is why the stop button works. Calling the timer functions(setPomodoro, setLongBreak, setShortBreak) resets their timer's to the original state. I can't seem to grasp how to resume from the timer's time when it's stopped.

When the set... functions are started with the buttons, you always initialise the times to starting values. Instead, if there is a timer already running you have to parse the paused time string into minutes and seconds and use those values to set your vars mins and secs.
Maybe something like this will work?
function setPomodoro() {
if(timer.innerHTML.length > 0){
var t = timer.innerHTML.split(':');
var mins = parseInt(t[0]);
var secs = parseInt(t[1]);
}
else{
var mins = 24;
var secs = 60;
}
var intervalID = setInterval(function() { //set unique interval ID for each SI func.
timer.innerHTML = mins + ':' + secs;
secs--;
if (secs === 0) {
mins--;
secs = 60;
}
}, 1000);
// 2.2 When stop button is clicked, timer stops
stopButton.addEventListener('click', function() {
clearInterval(intervalID);
}, false);
}

I have a basic timer where a user puts in a number, then it counts down until it hits 0.
I want the user to put another number while the timer for the prev is still going on. When the timer for the prev number hits 0, a new timer for the recently entered number will begin. My code somehow has both timers running concurrently despite my uses of setInterval and setTimeout.

q() is my awful attempt at trying to implement this. countDown() is the standalone implementation of the countdown, separate from this functionality.
EDIT: Why does the snippet not run my code but the browser does???? Not sure how to fix this
Good try, but each interval has no way of triggering the next one to start with a callback, and without that, they'll all run concurrently. Pass the q.shift()() in as a callback to the timer function which can be invoked when the timer runs out alongside clearTimeout, or write a loop and only run the 0-th timer if it exists.
Another problem: setTimeout is often mistaken to be perfectly accurate, but this is an incorrect assumption. The ms parameter only guarantees the timer will be invoked no sooner than the duration specified. The consequence of this is that it will accumulate drift. A more accurate approach is to use a date object to check the system's time.
Here's a proof-of-concept using the polling version:
const enqueueTimer = () => {
const sec = +els.data.value;
if (!Number.isInteger(sec)) {
els.timer.innerHTML = "Not a number!";
}
else if (sec < 0) {
els.timer.innerHTML = "Invalid timer setting!";
}
else {
timers.push({duration: sec * 1000});
}
};
const updateTimers = () => {
if (!timers.length) {
return;
}
const {duration, start} = timers[0];
const now = new Date();
if (!start) {
timers[0].start = now;
}
const elapsed = now - start || 0;
const remaining = duration - elapsed || 0;
const sec = remaining / 1000;
const ms = remaining % 1000;
els.timer.innerHTML = `${~~sec}.${("" + ms)
.slice(0, 2).padEnd(2)}`;
els.btn.innerHTML = "Ticking!";
if (elapsed >= duration) {
timers.shift();
if (timers.length) {
timers[0].start = new Date(start.getTime() + duration);
}
else {
els.data.value = "";
els.btn.innerHTML = "Start";
els.timer.innerHTML = "Countdown complete";
}
}
};
const els = {
btn: document.getElementById("btn"),
data: document.getElementById("data"),
timer: document.getElementById("timer"),
};
els.btn.addEventListener("click", enqueueTimer);
const timers = [];
setInterval(updateTimers, 100);

If it bothers you that the interval always runs, feel free to save the interval id, add a clearInterval() on the id when all the timers expire and kick off a new interval when a fresh timer is created.
I am trying to develop a centurion countdown timer for my website. It is a drinking game.
The way the timer works is: It is a 60 second countdown timer. Everytime the timer hits 0 it will +1 a shot counter and restart. It will do this 100 times.
The game is you must do 1 shot, every minute for 100 minutes. I am a beginner at JS and I am learning a lot, but I am seriously struggling to get this to work the way I want it to.
All I need is a "Start" Button, a "Pause" button and a "Reset" button but I can't seem to find a way to make these buttons work without messing the timer up.
Here is the HTML code:
<div class="inner">
<h1 class="heading alt">Centurions Timer</h1>
<p>1 Shot. Every Minute. 100 Minutes.</p>
<p>___________________________________</p>
<div id="timer">
<p id="seconds">60</p>
<p id="shots">0</p>
</div>
<input type="button" value="Start" onclick="timer()">
<input type="button" value="Pause" onclick="clearInterval(myTimer)">
</div>
and here is the JS code:
var seconds = 60;
var shots = 0;
var timer;
var c = 60;
function timer() {
timer = setInterval(myTimer, 1000)
}
function myTimer() {
document.getElementById("seconds").innerHTML = --c;
if (c == 0) {
shots = shots + 1;
c = 60;
}
document.getElementById("shots").innerHTML = shots;
}
If anyone could help me and show me what I am doing wrong and how I can make the code better, please do!
First, consider renaming either your method timer() or variable timer to disambiguate between the two.
Next, setInterval() returns an interval ID, which you store in timer.
clearInterval() takes the interval ID as the parameter, so try passing it the timer variable instead of myTimer (a function)
Little bit clean up needed. For clearInterval, u have to id of timer to clear
var seconds = 60;
var shots = 0;
var timer;
var c = 60;
function start() {
clearInterval(timer)
timer = setInterval(( ) =>{
updateUi()
}, 1000);
}
function pause() {
clearInterval(timer)
}
function updateUi() {
document.getElementById("seconds").innerHTML = --c;
if (c == 0) {
shots = shots + 1;
c = 60;
}
document.getElementById("shots").innerHTML = shots;
}
<div class="inner">
<h1 class="heading alt">Centurions Timer</h1>
<p>1 Shot. Every Minute. 100 Minutes.</p>
<p>___________________________________</p>
<div id="timer">
<p id="seconds">60</p>
<p id="shots">0</p>
</div>
<input type="button" value="Start" onclick="start()">
<input type="button" value="Pause" onclick="pause()">
</div>
You can also use Pub Sub model, to make code looks clean.
var seconds = 60;
var shots = 0;
var c = 60;
function Emitter() {
this.cb;
this.on = cb => {
this.cb = cb;
};
this.emit = () => {
this.cb && this.cb();
};
this.cancel = () => {
this.cb = null;
};
}
const emitter = new Emitter();
const tick = () => {
setInterval(() => {
emitter.emit();
}, 1000);
};
tick()
function start() {
emitter.on(updateUi);
}
function pause() {
emitter.cancel();
}
function updateUi() {
document.getElementById("seconds").innerHTML = --c;
if (c == 0) {
shots = shots + 1;
c = 60;
}
document.getElementById("shots").innerHTML = shots;
}
<div class="inner">
<h1 class="heading alt">Centurions Timer</h1>
<p>1 Shot. Every Minute. 100 Minutes.</p>
<p>___________________________________</p>
<div id="timer">
<p id="seconds">60</p>
<p id="shots">0</p>
</div>
<input type="button" value="Start" onclick="start()">
<input type="button" value="Pause" onclick="pause()">
</div>
<div class="inner">
<h1 class="heading alt">Centurions Timer</h1>
<p>1 Shot. Every Minute. 100 Minutes.</p>
<p>___________________________________</p>
<div id="timer">
<p id="minutes">100</p>
<p id="seconds">60</p>
<p id="shots">0</p>
</div>
<input type="button" value="START" onclick="start()">
<input type="button" value="PAUSE" onclick="pause()">
<input type="button" value="RESET" onclick="reset()">
</div>
Changed the onclick functions to something more meaningful. Added an extra button and some more logic to auto-stop when hitting the 100 minutes.
var seconds = 60,
minutes = 100,
shots = 0;
timer = "";
// this will just stop the timer, if you click start it will resume from where it left off
function pause() {
clearInterval(timer);
}
// resets seconds/minutes/shots, stops game
function reset() {
clearInterval(timer);
seconds = 60;
minutes = 100;
shots = 0;
timer = "";
document.getElementById("minutes").innerHTML = minutes;
document.getElementById("seconds").innerHTML = c;
document.getElementById("shots").innerHTML = shots;
}
// starts game from wherever it was left
function start() {
timer = setInterval(function() {
document.getElementById("seconds").innerHTML = c--;
if (c === 0) {
document.getElementById("minutes").innerHTML = --minutes;
// when 100 minutes are up, game will stop and reset
if (minutes === 0) {
reset();
}
shots++;
c = 60;
}
document.getElementById("shots").innerHTML = shots;
}, 1000)
}
I am trying to create html5 app that have a timer. After time end in 10 second, it will display a button. Supposed to be, once user click on the button, a popup will displayed and it will count the button click in a variable and reset the timer. The process will loop again. The issue is, after user click on the button, and after the timer finished countdown for second time, the button is not displaying.
Here is the Js codes:
<!-- Timer countdown -->
<script type=text/javascript>
var clicks = 0;
function showTimer(selector, seconds)
{
var startTime = Date.now();
var interval;
function showRemaining()
{
var delta = Date.now() - startTime; // milliseconds
var deltaSeconds = delta / (1000);
if (deltaSeconds < seconds) {
// display minutes remaining
$(selector).text(Math.round(seconds - deltaSeconds));
} else {
$(selector).text(0);
clearInterval(interval);
}
}
interval = setInterval(showRemaining, 1000);
showRemaining();
}
$(document).ready(function()
{
showTimer("#countdown", 10);
});
setTimeout(function()
{
$("#proceed").show();
}, 10000);
//when click button
function onClick() {
clicks += 1;
document.getElementById("proceed").style.visibility="hidden";
alert("Getting the message");
document.getElementById("clicks").innerHTML = clicks;
showTimer("#countdown", 10);
};
</script>
This is the HTML:
<h1>Test</h1>
<br>
<p ><span id="countdown"></span><br>
Timer Here<br>
<button type="button" id="proceed" onclick="onClick()">Click</button><br>
<a id="clicks">0</a></p>
you forget to show your button again, the way you did it , it's going to hide. remove the setTimeout since you know the end of your timer and also can repeat it.
var clicks = 0;
var interval = -1;
function showTimer(selector, seconds)
{
var startTime = Date.now();
function showRemaining()
{
var delta = Date.now() - startTime; // milliseconds
var deltaSeconds = delta / (1000);
if (deltaSeconds < seconds) {
// display minutes remaining
$(selector).text(Math.round(seconds - deltaSeconds));
} else {
$(selector).text(0);
clearInterval(interval);
$("#proceed").show(); // Look at here
}
}
if( interval > -1 ) clearInterval(interval);
interval = setInterval(showRemaining, 1000);
showRemaining();
}
$(function() {
showTimer("#countdown", 10);
});
//when click button
function onClick() {
$("#proceed").hide();
alert("Getting the message");
$("#clicks").text(++clicks);
showTimer("#countdown", 10);
};

Problem: I have three buttons that set different timers. When I click the timer buttons after a first click, it doesn't reset the timer, but continues the timer where it left off.
Desired Result: When I click the timer buttons (Pomodoro, lng break, shrt break) I want the timer to reset. EG: Pomodoro is set for 24mins 60seconds. If I click the same Pomodoro button when the timer is say, 23 mins, I want it to reset to the original 24mins, 60 seconds.
Re-created the situation:
Here is my javascript, and html. I will also post a JSBin since I am still not sure how to do code snippets yet.

shortBreak = document.querySelector('#short-brk'),
stopButton = document.querySelector('#stop'),
startButton = document.querySelector('#start'),
resetButton = document.querySelector('#reset'),
container = document.querySelector('#container'),
timer = document.querySelector('#timer'),
seconds = 60; //set seconds
// Click event for break timers.
container.addEventListener('click', function(e) {
// store event target
var el = e.target;
if (el === pomodoro) {
setPomodoro();
} else if (el === longBreak) {
setLongBreak();
} else if (el === shortBreak) {
setShortBreak();
}
e.stopPropagation();
}, false);
// 1.1a Create a timer that counts down from 25 minutes.
function setPomodoro() {
var pomodoroMins = 24;
var intervalID = setInterval(function() { //set unique interval ID for each SI func.
timer.innerHTML = pomodoroMins + ':' + seconds;

// 2.2 When stop button is clicked, timer stops
stopButton.addEventListener('click', function(){

window.onload = function () { timer1.start(20); };
</script>
</div>
</asp:Panel>
<asp:Literal ID="Literal1" runat="server"></asp:Literal></div>
</form>
</body>
</html>
in this code , I have called the timer 2 times with different intervals but its just run with the last interval value .
Unless I'm missing something, it looks like it's just because you're setting the two values in both timers with:
$('div.timer span.second').html(second);
$('div.timer1 span.second').html(second);
Instead pass the selector into the constructor like so:
function _timer(selector, callback) {
Then change your visual updates to:
$(selector + ' span.second').html(second);
And new up your timers like:
timer = new _timer
(
".timer",
function(time)
{
...
and:
timer1 = new _timer
(
".timer1",
function(time)
{
...
Edit: I went back & looked... the reason only one timer is actually running is because you're using window.onload to setup the start calls, so the second one is simply replacing the first. Without completely changing your code, the easiest solution to fix this specific issue is to use jQuery to attach your load events (since jQuery allows adding multiple event handlers out of the box):
$(window).load(function () { timer.start(806); });
and
$(window).load(function () { timer1.start(20); });
