I want my button to change color if clicked but it seems not working in this JQuery-Mobile. and If its clicked it seems like it increases the time count speed i dont know why.
Any help please guys.
var seconds = 0;
var minutes = 0;
var timer = null;
function toggle(ths) {
var clicked = $(ths).val();
$(ths).toggleClass("btnColor");
$("#tb").toggleClass("btnColorR");
$("#lblType").html(clicked);
$("#setCount").html(" minutes : " + minutes + " seconds : " + seconds);
//duration time
seconds = seconds + 1;
if (seconds % 60 == 0) {
minutes += 1;
seconds = 0;
}
timer = timer = setTimeout("toggle()", 1000);
}
try :
timer=setTimeout(function(){
toogle();
},1000);

I'm currently trying to set a timer for each div created, whereby each div has a background color of green or red depending on if there are detections in the webRTC video. Is there a way to assign a timer to the divs individually? Or maybe to only check for my own video? I've tried something like below, but it does not work when there are more than 1 people in the call, as "time" will be a global variable. I've also tried something like time = Math.ceil((time+1)/checkerBox.length) , but it does not seem to work too. Any pointers will be helpful
function checker(){
var time =0;
var timer = setInterval(function (){
for(var i=0;i<checkerBox.length;i++){
if(checkerBox[i].style.backgroundColor=="red"){
time = time + 1;
console.log("Box" + videoNum[i].innerHTML + " is not present for : " + checkerBox[i].innerHTML + " seconds");
}else{
time = 0;
}
//Exceed time
if(checkerBox[i].innerHTML == 30){
setTimeout(function(){
takeScreenshot(videoNum[i-1]);
}, 100);
time = 0;
}
checkerBox[i].innerHTML = time;
}
},1000)
}
Update : I ended up using arrays
var takenFrom;
var d = new Date();
let timeKeep = new Array(0,0,0,0,0,0,0,0,0,0,0);
let screenShots = new Array(0,0,0,0,0,0,0,0,0,0,0);
function checker(){
timer = setInterval(function (){
for(var i=0;i<=(checkerBox.length)-1;i++){
tableRow[i+1].cells[2].innerHTML = timeKeep[i]
tableRow[i+1].cells[3].innerHTML = screenShots[i]
if(flag[i].innerHTML=="0"){
checkerBoxFalse(checkerBox[i]);
timeKeep[i] = timeKeep[i] + 1;
console.log("Box" + videoNum[i].innerHTML + " is not present for : " + tableRow[i+1].cells[2].innerHTML + " seconds");
if(tableRow[i+1].cells[2].innerHTML == 10 ){
takenFrom = "Box" + videoNum[i].innerHTML + "minute" + d.getMinutes() + " room" + ROOM_ID
takeScreenshot(videoNum[i],takenFrom);
screenShots[i] = screenShots[i] + 1;
timeKeep[i] = 0;
}
} else if(flag[i].innerHTML== "1"){
checkerBoxTrue(checkerBox[i]);
timeKeep[i] = 0;
}
}
},1000)
}
Yes:
for (let div of divs) {
setInterval(function() {
//do something with div
}, 1000);
}
let is block scoped, so each setInterval will have its own div.
I have made a countdown but now I want to make a input field with how many minutes the countdown should countdown from. What I have is a pretty basic countdown but what I don't have is that a user puts the amount of minutes into the input field, click the button, and it counts down the minutes. And I hope someone can help me with this.
This is what I got so far:
(()=> {
let countdownEnded = false;
start(3600); // seconds
})();
function start(inputTime){
let startTime = Date.now();
intervalSeconds = setInterval(() => {
let currentTime = Date.now() - startTime;
if(inputTime < 1) {
stop();
} else {
updateDisplay(inputTime, currentTime);
updateMillis();
}
}, 1000);
}
function stop(){
let countDivElement = document.getElementById("countdown"); /*** Updated***/
countDivElement.innerHTML = 'countdown done';
countdownEnded = true; /*** Updated***/
}
function updateDisplay(seconds, currentTime){
let timeIncrement = Math.floor(currentTime / 1000);
updateTime(seconds - timeIncrement);
}
/**
* #method - updatesecondsond
* #summary - This updates the timer every seconds
*/
function updateTime(seconds) {
let countDivElement = document.getElementById("timer");
let minutes = Math.floor(seconds / 60);
let remainingSeconds = seconds % 60;
if (remainingSeconds < 10) {
remainingSeconds = '0' + remainingSeconds;
}
if (minutes < 10) {
minutes = '0' + minutes;
}
if (seconds > 0) {
seconds = seconds - 1;
} else {
clearInterval(intervalSeconds);
countdownEnded = true;
countDivElement.innerHTML = 'countdown done';
return null;
}
countDivElement.innerHTML = minutes + ":" + remainingSeconds + ":" ;
};
function updateMillis() {
let countMillsElement = document.getElementById('millis');
let counterMillis = 99;
let millis;
let intervalMillis = setInterval(()=> {
if(counterMillis === 1) {
counterMillis = 99;
} else {
millis = counterMillis < 10 ? '0' + counterMillis : counterMillis;
};
countMillsElement.innerHTML = millis;
counterMillis --;
}, 10);
if(countdownEnded) {
stop(); /*** Updated***/
return clearInterval(intervalMillis);
}
};
<div class="clock" id="model3">
<div id="countdown"> <!-- Updated -->
<span id="timer"></span><span id="millis"></span>
</div>
</div>
<input id="minutes" placeholder="0:00"/>
I think this may help you.
Change the following
<input id="minutes" placeholder="00"/> <button onclick="startTimer()">Start</button>
And in javascript add a new function
function startTimer(){
var x=document.getElementById("minutes").value * 60; //To Change into Seconds
start(x);
}
And remove the start function
Just add a button with click event that takes input value and triggers your 'start' function with that value as parameter. Something like this:
document.getElementById("startBtn").addEventListener("click", startTimer);
function startTimer() {
var numberOfMinutes = Number(document.getElementById("minutes").value) * 60;
start(numberOfMinutes);
}
And remove 'start' function call from the window load to prevent the timer to start immidiately.
Result is something like this:

I am building a pomodoro clock/countdown, but have an issue with formatting selected time to minutes/hours/seconds. I have tried to multiply the secs variable with 60 (secs*=60), but it makes a mess and I can't figure out how to fix it. So, I would like it to "know" that it needs to count down from 25 minutes - in 25:00 format, or more/less(hh:mm:ss) if the user chooses so with + and - buttons. All help very appreciated

<h1 id="num">25 min</h1>

<button onclick='increaseNumber()'>+</button>
<button onclick='decreaseNumber()'>-</button>
<script src="script.js"></script>

and here is javascript:
var num = document.getElementById('num').innerHTML;
var secs = parseInt(num);
function countDown(secs, elem) {
var element = document.getElementById(elem);
secs--;
var timer = setTimeout(function() {
countDown(secs, elem);
}, 1000);
//secs *= 60;
if(secs%60 >= 10){ //10 - if it's not a single digit number
document.getElementById('num').innerHTML = (Math.floor(secs/60) + ":" + secs%60);
}
else{
document.getElementById('num').innerHTML = (Math.floor(secs/60) + ":" + "0" + secs%60);
}
element.innerHTML = "Please wait for "+secs+" minutes";
//if timer goes into negative numbers
if(secs < 1){
clearTimeout(timer);
element.innerHTML = '<h2>Countdown complete!</h2>';
element.innerHTML += 'Click here now';
}
}
function increaseNumber() {
secs += 5;
document.getElementById('num').innerHTML = secs + ' min';
}
function decreaseNumber() {
if(secs >= 10) {
secs -= 5;
document.getElementById('num').innerHTML = secs + ' min';
}
}
Is there a reason you're doing it by hand ?
If you don't mind using a library, moment.js does a very good job at time manipulations. It's lightweight and very easy to use.
If you have to do it by hand because of some limitations, what are they ?
For reference:
//Creates a moment. Its value is the time of creation
var timer = moment();
//add 60 seconds to the timer
timer.add(60, 's');
//Removes 1 minutes from the timer
timer.subtract(1, 'm');

Substract
Try this countDown function:
function countDown(secs, elem) {
var element = document.getElementById(elem);
element.innerHTML = "Please wait for "+secs+" minutes";
var second = 0;
var timer = setInterval(function(){
var extraZero = second < 10 ? '0' : '';
document.getElementById('num').innerHTML = secs + ":" + extraZero + second;
if (second-- === 0) {
second = 59;
if (secs-- === 0){
clearInterval(timer);
element.innerHTML = '<h2>Countdown complete!</h2>';
element.innerHTML += 'Click here now';
}
}
}, 1000);
}
Since you are counting down the seconds, it is making more sense to use setInterval instead of setTimeout.
If requirements are met when you click the button it will display a count down timer. Problem is it displays the countdown timer BEFORE you even click the button. I'm not sure what I'm overlooking.

You need to move countdownTimer variable into your timer() function.
Try changing the last lines of timer() to be like this:
if (seconds == 0) {
document.getElementById('countdown').innerHTML = "Completed";
} else {
seconds--;
setTimeout(timer, 1000);
}
and remove the setInterval line.
Speaking generally, setTimeout is much preferred to setInterval, because it doesn't require a managed state (countdownTimer in your example) and is far more flexible.
Also note that passing a string as in setTimeout('timer()', 1000) is obsolete, just pass a function: setTimeout(timer, ...).
This line
var countdownTimer = setInterval('timer()', 1000);
will execute 1 second after the page loads as well as on the button click and this calls the display_timer function.
you have called it in setInterval function, so it will starts immediately , because setInterval function runs after page loads and not on click and setInterval uses your function

The code below it counts minutes and seconds if the toggle button is clicked.
Is it possible to make it cancel everything if its clicked/toggled, meaning that i can be able to clicked another toggle button.
function toggle(ths) {
var clicked = $(ths).val();
$("#lblType").html(clicked);
$("#setCount").html(" minutes : " + minutes + " seconds : " + count);
count = count + 1;
if (count % 60 == 0) {
minutes += 1;
count = 0;
}
timer = setTimeout("toggle()", 1000);
}
<div ><label id="lblType"></label>
<label id="setCount"></label>
</div></p>
<div id="planned"></div>
Just call clearTimeout():
clearTimeout(timer);
You can use clearTimeout()
clearTimeout(timer);
https://developer.mozilla.org/en/docs/DOM/window.clearTimeout
window.clearTimeout(timer)
Check http://www.w3schools.com/js/js_timing.asp for more info.
By using cleartimeout(); clearinterval();
http://www.w3schools.com/jsref/met_win_cleartimeout.asp
var timer=null;
function toggle(ths) {
var clicked = $(ths).val();
$("#lblType").html(clicked);
$("#setCount").html(" minutes : " + minutes + " seconds : " + count);
count = count + 1;
if (count % 60 == 0) {
minutes += 1;
count = 0;
}
timer = setTimeout("toggle()", 1000);
}
function quitTimer(){
window.clearTimeout(timer);
timer = null;
}
