How to show the count down in angular js - javascript

Trying to create a count down demo, using angular js.
Once am in idle state for 30 seconds, i need to show the count down starting from 10 to 0,
How to implement the count down timer.
this is what I have tried.
var time = $timeout(function () {
$rootScope.$broadcast('shutdwon');
setTimeout( function () {
$location.path('/');
}, 1500);
}, 30000);

Its simple try this out
Working Demo
html
<div ng-app ng-controller="countController">Count starts after 30 seconds<div>Count :: {{countDown}}</div>
<div>
script
function countController($scope, $timeout) {
$scope.countDown = 10;
var time = $timeout(function () {
var timer = setInterval(function () {
if ($scope.countDown > 0) {
$scope.countDown--;
} else {
clearInterval(timer)
}
$scope.$apply();
}, 1500);
}, 30000);
}

I have done this kind of thing to show the session time out information.
Check the following sample code. Which can be improved and used according to your requirements.
function MyCtrl($scope,$timeout) {
$scope.isUserActive = false;
$scope.userActivityInterval = 1000;
$scope.redirectLoginInterval =10000;
$scope.timerSpan= $scope.redirectLoginInterval/ $scope.userActivityInterval;
$scope.resetActivity=function () {
if ($scope.isUserActive == true) {
clearTimeout($scope.redirectTimer);
$scope.redirectTimer = $timeout( $scope.redirectToLogin, $scope.redirectLoginInterval);
$scope.timerSpan = $scope.redirectLoginInterval/ $scope.userActivityInterval;
}
else {
$scope.timerSpan -= $scope.userActivityInterval / $scope.userActivityInterval;
}
clearTimeout($scope.activityTimer);
$scope.activityTimer = $timeout($scope.resetActivity, $scope.userActivityInterval);
$scope.isUserActive = false;
};
$scope.activityTimer = $timeout($scope.resetActivity, $scope.userActivityInterval);
$scope.redirectTimer = $timeout($scope.resetActivity, $scope.redirectLoginInterval);
}

Scripts crashing each other

well my problem is hopefully easy: 3 actions that shall happen while hovering a photo. The timer at the bottom works now, the other things crashed. A Page shall open in 5 seconds and the photo shall move out of the display before. Sounds easy, doesnt it? I hope so.
Do you guys know what I can do?
Thanks already and best regards!
<script>
var interval;
var timer = 5;
$('.HoverBalken').on({'mouseover': function () {
timer = setTimeout(function () {
$('.HoverBalken').toggleClass('HoverBalken-active');
$('.N').toggleClass('N-active');
$('.K').toggleClass('K-active');
}, );
timer = setTimeout(function () {
window.location = "FoliagePlates.html"
}, 5000);
}, 'mouseover': function () {
interval = setInterval(function() {
timer--;
$('.timer').text(timer);
if (timer === 0) clearInterval(interval);
}, 1000);
}, 'mouseout' : function () {
clearTimeout(timer);
$('.HoverBalken').removeClass('HoverBalken-active');
$('.N').removeClass('N-active');
$('.K').removeClass('K-active');
clearInterval(interval);
timer = 5;
$('.timer').text(timer);
}
});
</script>
<script>
var interval;
var timer = 5;
var timeout1,timeout2;
$('.HoverBalken')
.mouseover(function() {
//use different variable than your timer
timeout1 = setTimeout(function () {
$('.HoverBalken').toggleClass('HoverBalken-active');
$('.N').toggleClass('N-active');
$('.K').toggleClass('K-active');
}, 2000); //forgot time here
//use different variable than your timer and first timeout
timeout2 = setTimeout(function () {
window.location = "FoliagePlates.html"
}, 5000);
//stay in same scope, don't define event again
interval = setInterval(function() {
timer--;
$('.timer').text(timer);
if (timer === 0) clearInterval(interval);
}, 1000);
})
.mouseout(function() {
//clear both timers
clearTimeout(timeout1);
clearTimeout(timeout2);
$('.HoverBalken').removeClass('HoverBalken-active');
$('.N').removeClass('N-active');
$('.K').removeClass('K-active');
clearInterval(interval);
timer = 5;
$('.timer').text(timer);
});
</script>
this should fix it, notice the comments in code

Cant a function be implemented into while loop?

function start() {
var work = document.getElementById("work").value;
var rest = document.getElementById("rest").value;
var rounds = document.getElementById("rounds");
var timer = document.getElementById("timer");
function countdown() {
var roundsValue = rounds.value;
while (roundsValue > 0) {
var worktime = setInterval(function () {
timer.value = work + "sec";
work = work - 1;
if (work === 0) {
clearInterval(worktime);
}
}, 1000);
var resttime = setInterval(function(){
timer.value = rest + "sec";
rest = rest-1;
if(rest === 0){
clearInterval(resttime);
}
}, 1000);
roundsValue = roundsValue-1;
}
}
}
I am working on my javascript progress right now and I came here with this problem. I want to repeat the same amount of work time and rest time as rounds are but it doesnt work like this and I cant help myself. For example: 8 rounds of 10 seconds of work and then 5seconds of rest. It maybe doesnt work because function cant be implemented into a WHILE loop.

Here is a quick fix, may not be the best way to go about it but will get what to do.
http://jsfiddle.net/sahilbatla/shhyq02e/6/
function start() {
var rounds = document.getElementById("rounds");
var timer = document.getElementById("timer");
var roundsValue = parseInt(rounds.value);
(function countdown() {
var work = document.getElementById("work").value;
var rest = document.getElementById("rest").value;
if (roundsValue > 0) {
var worktime = setInterval(function () {
timer.value = work + "sec(work)";
work = work - 1;
if (work === 0) {
clearInterval(worktime);
var resttime = setInterval(function() {
timer.value = rest + "sec(rest)";
rest = rest - 1;
if (rest === 0) {
clearInterval(resttime);
--roundsValue;
countdown();
}
}, 1000);
}
}, 1000);
}
})();
}

javascript autoreload in infinite loop with time left till next reload

i need a JavaScript, that relaods a page every 30 seconds, and will show how much time there is until next reload at the ID time-to-update, Example:
<p>Refreshing in <span id="time-to-update" class="light-blue"></span> seconds.</p>
i also need it to repeat itself infinitely.
thank you for reading, i hope it helps not me but everyone else, and a real big thank you if you could make this script.
(function() {
var el = document.getElementById('time-to-update');
var count = 30;
setInterval(function() {
count -= 1;
el.innerHTML = count;
if (count == 0) {
location.reload();
}
}, 1000);
})();
A variation that uses setTimeout rather than setInterval, and uses the more cross-browser secure document.location.reload(true);.
var timer = 30;
var el = document.getElementById('time-to-update');
(function loop(el) {
if (timer > 0) {
el.innerHTML = timer;
timer -= 1;
setTimeout(function () { loop(el); }, 1000);
} else {
document.location.reload(true);
}
}(el));
http://jsfiddle.net/zGGEH/1/
var timer = {
interval: null,
seconds: 30,
start: function () {
var self = this,
el = document.getElementById('time-to-update');
el.innerText = this.seconds; // Output initial value
this.interval = setInterval(function () {
self.seconds--;
if (self.seconds == 0)
window.location.reload();
el.innerText = self.seconds;
}, 1000);
},
stop: function () {
window.clearInterval(this.interval)
}
}
timer.start();

Stop countdown on click

I want my countdown to stop on the click of a submit button, i searched in some pages,
but I didn't found anything.
Here is the code i want to stop on click
function countDown (count) {
if (count > 0) {
var d = document.getElementById("countDiv");
d.innerHTML = count;
setTimeout (function() { countDown(count-1); }, 1000);
document.getElementById('tiempo').value = count;
}
else
document.location = "timeover.php";
}
document.getElementById("palabra").focus();
countDown(5);
</script>
You have to save reference to timeout (actually return value of timeout will be number) and use it to cancel timeout.
var timeout = window.setTimeout(function () {
// do something
}, 1000);
// clear timeout
window.clearTimeout(timeout);
You probably got the idea. By the way, you should probably look at setInterval method since it would be better in this situation. Interval will "tick" as long until you cancel it.
Try something like this:
var stopped = false;
function countDown (count) {
if (count > 0) {
var d = document.getElementById("countDiv");
d.innerHTML = count;
document.getElementById('tiempo').value = count;
if (!stopped) {
setTimeout (function() { countDown(count-1); }, 1000);
}
}
else
document.location = "timeover.php";
}
document.getElementById("palabra").focus();
document.getElementById("mySubmitId").onclick = function () {
stopped = true;
};
countDown(5);

clearInterval(); then call interval again

I have a setInterval function
var auto_refresh = setInterval(function () {
if ($('#addNewJuicebox:visible')) {
clearInterval();
}
//rest of function
}, 8000); // refresh every 5000 milliseconds
I want to call the setInterval later again, what's the best way to do that?
Try breaking your code up into the storage of the interval and the setting.
var auto_refresh = "";
function startRefresh() {
if (auto_refresh != "") {
// already set
return;
}
auto_refresh = setInterval(function() {
if ($('#addNewJuicebox:visible')) {
clearInterval(auto_refresh);
auto_refresh = "";
}
}, 8000);
}
Added a jsfiddle example for demonstrating starting and stopping an interval
http://jsfiddle.net/Jf8PT/
This may be what you're looking for
Function TaskRunner(run, interval) {
this._taskId = null;
this._run = run;
this._interval = interval
}
TaskRunner.prototype.start = function(){
if (this._taskId) {
return; // Already running
}
this._taskId = setInterval(this._taskId, this._interval);
}
TaskRunner.prototype.stop = function(){
if (!this._taskId) {
return; // Not running
}
clearInterval(this._taskId);
this._taskId = null;
}
var task = new TaskRunner(
function(){
if ($('#addNewJuicebox:visible')) {
task.stop();
}
// Do the update
}, 5000);
Now you can call `task.start()` from anywhere in your code to restart it.
clearInterval takes in a reference to the timer that you want to clear, you need to pass that in to it:
var auto_refresh = null;
var refresh = function () {
if ($('#addNewJuicebox').is(':visible')) {
clearInterval(auto_refresh);
auto_refresh = null;
}
};
var start_refreshing = function() {
if(auto_refresh != null) return;
auto_refresh = setInterval(refresh, 8000);
};
start_refreshing();
Maybe you just want to use setTimeout() instead, so that you have the control you're looking for?
