Here is an example of a timer http://www.prezzipazzi.com/prodotto.php?id=1809
and I need a code that when the timer reaches 0 it click automatically on the button1809.
I tried this but it does not work:
var waitForZeroInterval = setInterval (CheckForZero, 0);
var hasRun = false;
function CheckForZero () {
if ( (unsafeWindow.seconds == 0) && (unsafeWindow.milisec == 0) )
{
clearInterval (waitForZeroInterval);
var targButton = document.getElementById ('bottone1809');
var clickEvent = document.createEvent ('MouseEvents');
clickEvent.initEvent ('click', true, true);
targButton.dispatchEvent (clickEvent);
};
if (!hasRun) {
hasRun = true;
setInterval(CheckForZero, 35000);
};
}
Does it click the button one time and then stop, or not click the button at all?
It looks like the hasRun logic is wrong.
I can't test at that site since (1) it annoys me greatly, (2) It seems to require a registration -- which I will not do. So, please confirm that it operates like this:
You login and load an auction page -- 1809 in this example.
The 30-second timer starts. When it hits 0, you click.
The timer resets -- Is there a delay? -- to a new 30-second countdown but the auction remains the same.
Repeat, ad nauseam.
If all that is true, and the current code clicked the button once, then this should work:
var waitForZeroInterval = null;
function RestartZeroCheck () {
waitForZeroInterval = setInterval (CheckForZero, 100);
}
function CheckForZero () {
if ( (unsafeWindow.seconds == 0) && (unsafeWindow.milisec == 0) )
{
clearInterval (waitForZeroInterval);
var targButton = document.getElementById ('bottone1809');
var clickEvent = document.createEvent ('MouseEvents');
clickEvent.initEvent ('click', true, true);
targButton.dispatchEvent (clickEvent);
//--- After a short pause, start checking for the next timer to zero.
setTimeout (RestartZeroCheck, 333);
};
}
RestartZeroCheck ();
Note that if that works, then examining the page's structure suggests that this:
var targButton = document.getElementById ('bottone1809');
Can be changed to this:
var targButton = document.querySelector (
"#left-inside div.post-wrapper td center input[id^='bottone']"
);
So that the auction number does not have to be hard-coded.
some more update:
HTML
<input type="button" name="button1" id="button1" onclick="do_some();"/>
script
var waitForZeroInterval = setInterval (function(){}, 0);
var hasRun = false;
function CheckForZero () {
clearInterval (waitForZeroInterval);
jQuery('#button1').click();
}
if (!hasRun) {
hasRun = true;
waitForZeroInterval = setInterval(CheckForZero(), 1000);
}
function do_some(){
alert("thank you");
}
This is working fine.. i have tested. i am getting that alert after 1 sec. The button is clicked and then the do_some function is called to display alert.

I'm working on a quiz page where I have a timer that I would like to be able to toggle on or off so it doesn't distract the user, and save the setting after submitting an answer. The timer function works, and calls on localStorage.getItem(). But when I try the below with a boolean to see if the showHideTimer() button is clicked, the timer always shows up when the next question appears. The console always logs true when the page loads a new question.
<script>
var clickCookie = 'clicked';
var clicked = localStorage.getItem(clickCookie);
console.log(clicked);
function showHideTimer(){
if(clicked==true){
document.getElementById("testHeaderRight").style.color = "black";
clicked=false;
localStorage.setItem(clickCookie, clicked);
console.log(clicked);
return clicked;
}
else{
document.getElementById("testHeaderRight").style.color = "white";
clicked=true;
localStorage.setItem(clickCookie, clicked);
console.log(clicked);
return clicked;
}
};
window.onload = function(){
if(clicked===null){
localStorage.setItem(clickCookie, false);
} else {
showHideTimer(clickCookie);
}
};
</script>
<body>
<button id="showHideTimer" onclick="showHideTimer()">Toggle Timer</button>
<div id="testHeaderRight">
Time Remaining :
<span id="time"></span>
</div>
<script>
var cookieName = 'startTimer';
var savedSeconds = localStorage.getItem(cookieName);
function startTimer(duration, display) {
var timer = duration, seconds;
setInterval(function () {
seconds = parseInt(timer);
display.textContent = secondsToHms(seconds);
var runningTime = (parseInt(seconds));
localStorage.setItem(cookieName, runningTime);
}, 1000);
}
window.onload = function () {
var startTime = 7200,
display = document.querySelector('#time');
if (savedSeconds === null){
startTimer(startTime, display);
} else {
startTimer(savedSeconds, display);
}
};
</script>
</body>
I've tried moving the window.onload call into the same function as the timer since that is functioning properly, but seems to make no difference. I've tried switching the clicked=true/false; variables around to make sure I'm not confusing myself with booleans, and they switch freely in the console when clicking on the button. I've tried changing the return value of the showHideTimer() function to be localStorage.setItem(clickCookie, clicked);
When you get the item out of storage it's a string, "true", not a boolean.
So your if(clicked==true) comparison never passes and you end up on the "false" path every time.
hello i try to create the function to prevent the other function to run for 10 minutes IF user close the content and refresh the page.
the other function is to show the content when we scroll with 2 argument
first: it will run the function with first argument with no interval, if user click close and refresh. it will run the second argument that give interval
heres my code.
https://jsfiddle.net/8c1ng49a/1/
please look this code
var popUp= document.getElementById("popup");
var closePopUp= document.getElementsByClassName('popup-close');
var halfScreen= document.body.offsetHeight/2;
var showOnce = true;
var delay;
function slideUp(){
popUp.style.maxHeight="400px";
popUp.style.padding="10px 20px";
popUp.style.opacity="1";
if(popUp.className==="closed"){
popUp.className="";
}
}
function slideDown(){
popUp.style.maxHeight="0";
popUp.style.padding="0 20px";
popUp.style.opacity="0";
// add class closed for cache
if(popUp.className===""){
popUp.className="closed";
localStorage.setItem('closed', 'true'); //store state in localStorage
}
}
// start interval
function startDelay() {
delay = setInterval(slideUp, 1000);
}
// clear interval
function clearDelay() {
window.clearTimeout(delay);
}
// check if cache heve class close
window.onload = function() {
var closed = localStorage.getItem('closed');
if(closed === 'true'){
popUp.className="closed";
}
}
// show popup when scroll 50%
window.onscroll = function scroll(ev) {
// first time visited
if ((window.innerHeight+window.scrollY) >= halfScreen && showOnce) {
slideUp();
showOnce = false;
}
//same user mutilple time visited the site
else if((popUp.className==="closed" && window.innerHeight+window.scrollY) >= halfScreen && showOnce ){
startDelay();
showOnce = false;
}
};
// close button when click close
for(var i = 0; i<closePopUp.length; i++){
closePopUp[i].addEventListener('click', function(event) {
slideDown();
});
}
my interval didnt work onthe second argument its fire when i refresh, i dont know why.
but if add startDelay on my first arguments its work. but i need to place the interval on my second argu
When you want to make delay use setTimeout function.
Here is documentation of this function.
setInterval Repeatedly calls a function or executes a code snippet, with a fixed time delay between each call.
I have a function which will take some time to run on click event.
Following is merely an example and setTimeout is there only to simulate time it may take to run it. How can I ensure when a user click on an item any previous running function(s) is(are) cancelled and only the latest onclick function is fired?
i.e. if a user clicked on it 10 times. I want to only execute the only the 10th click not the 9 clicks before.
I am hoping for a pure/vanilla js solution... NOT jQuery
(function () {
var nav = document.querySelector('.nav__toggle');
var toggleState = function (elem, one, two) {
var elem = document.querySelector(elem);
elem.setAttribute('data-state', elem.getAttribute('data-state') === one ? two : one);
};
nav.onclick = function (e) {
setTimeout(function(){
toggleState('.nav ul', 'closed', 'open');
}, 5000);
e.preventDefault();
};
})();

You need to debounce your click handler.
var button = document.getElementById("debounced");
var clickHandler = function() {
alert('click handler');
}
var debounce = function(f, debounceTimeout) {
var to;
return function() {
clearTimeout(to);
to = setTimeout(f, debounceTimeout);
}
}
button.addEventListener('click', debounce(clickHandler, 5000));
<button id="debounced" href="#">debounced</button>
Or use underscore/lodash https://lodash.com/docs#debounce
I have made a custom slider with jQuery. For this I have used setInterval function:
timer = setInterval(function() {}, 8000);
But I cannot pause and resume the interval. I have 2 buttons (play, pause) which I want to use for. Lets say I click pause after 3 sec, and then resume it. So it should stay in that slider for 5 more seconds and then go to the next one and continue 8 seconds each. I have seen this kinda slider with mouseover pause, but can't do it by myself. I have tried this:
clearInterval(timer);
But this seems reset the interval, don't pause. Can anyone help :)
I'm not entirely sure that's something native to jQuery, however, you could use a flag to pause it, and check in your setInterval whether to execute.
Edit:
Found something that might be useful to you, the jquery-timer
Alternitively, you can keep track of the id set by setInterval, and clear out out when you'd like to pause. Then you can set it again when you wish to resume:
var id = window.setInterval(<code>); //create
window.clearInterval(id); //pause
id = window.setInterval(<code>); //resume
there are two ways of accomplish this:
Clearing the interval everytime you pause and starting a new interval when you resume it.
Having a flag to tell the function in the interval when it is paused and it should not do anything.
The first solution would work like this:
let intervalId = false;
const intervalLength = 8000; // 8 seconds
function intervalFunction () {
// do stuff.
}
startButton.onclick = function () {
if (intervalId === false) {
intervalId = setInterval(intervalFunction, intervalLength);
}
}
pauseButton.onclick = function () {
if (intervalId !== false) {
clearInterval(intervalId);
intervalId = false;
}
}
// auto start it:
intervalId = setInterval(intervalFunction, intervalLength);
The second solution would work like this:
var isRunning = true;
var interval = setInterval(function() {
if (!isRunning) {
// not running, do nothing
} else {
// it is running, do stuff.
}
}, 8000);
pauseButton.onclick = function () {
isRunning = false;
};
startButton.onclick = function () {
isRunning = true;
};
I am not complete sure, that what you are asking for, is the right thing you are showing us... setInterval basically is pure native javascript and in my opinion not worth using! If you wan't to set your timeouts via jquery try this link: http://jchavannes.com/jquery-timer. You can find usages there...
Now on to your problem... you need a state to check wether the slider has to slide or not... simply set a bool like this...
var timer;
var doSlide = false;
var i = 0;
function Slide(){
timer = setTimeout(function(){
if(doSlide == true){
Slide();
i++; // Same as i = i + 1
console.log('Sliding');
if(i == 3) AbortSlide(); /* Abort on third slide! Dont use this in your logic!*/
} else if(doSlide == false){
console.log('Sliding aborted untill next RunSlide() call!')
clearTimeout(timer);
}
},1000);
}
function AbortSlide(){
doSlide = false;
i = 0; // Resetting the count! Dont use this in your logic!
}
function RunSlide(){
doSlide = true;
Slide();
}
RunSlide();
You could also empty the interval in the abort method:
function AbortSlide(){
doSlide = false;
clearTimeout(timer);
i = 0; // Resetting the count! Dont use this in your logic!
}
Here is a working fiddle i made for you to understand what timers and intervals are for: https://jsfiddle.net/q5qzmv68/7/
Hope this helps! Cheers!
hey, how can I have my download link hidden, and make a count down type thing. Maybe have it count down from 10 and once it's done that have the download link appear, it would be best to do it in js right?
does anyone know how to do this? :D
Thanks
Complete example:
<span id="countdown"></span>
<a id="download_link" href="download.zip" style="display:none;">Download</a>
<noscript>JavaScript needs to be enabled in order to be able to download.</noscript>
<script type="application/javascript">
(function(){
var message = "%d seconds before download link appears";
// seconds before download link becomes visible
var count = 10;
var countdown_element = document.getElementById("countdown");
var download_link = document.getElementById("download_link");
var timer = setInterval(function(){
// if countdown equals 0, the next condition will evaluate to false and the else-construct will be executed
if (count) {
// display text
countdown_element.innerHTML = "You have to wait %d seconds.".replace("%d", count);
// decrease counter
count--;
} else {
// stop timer
clearInterval(timer);
// hide countdown
countdown_element.style.display = "none";
// show download link
download_link.style.display = "";
}
}, 1000);
})();
</script>
You can use setInterval for this. setInterval behaves like a timer, where you can run a certain function periodically. Something like this should do the work(untested):
$(".link").hide();
var iteration = 0;
var timer = setInterval(function() {
if(iteration++ >= 10) {
clearTimeout(timer);
$(".link").show();
$(".counter").hide();
}
$(".counter").text(10 - iteration);
}, 1000);
This will initially hide the download link and run a function every second which counts down from 10. When we reaced ten, we hide the counter and show the link. ClearTimeout is used so that we don't count after we reached ten. Easy as dell.
Edit: As mentioned in the comments, this function is using jQuery to find the elements.
Take a look at the setTimeout function. You can do something like:
function displayLink() {
document.getElementById('link_id').style.display = 'block';
}
setTimeout(displayLink, 10000);
var WAIT_FOR_SECONDS = 10;
var DOWNLOAD_BUTTON_ID = "btnDownload";
if (document.body.addEventListener) {
document.body.addEventListener("load", displayDownloadButton, false);
} else {
document.body.onload = displayDownloadButton;
}
function displayDownloadButton(event) {
setTimeout(function() {
_e(DOWNLOAD_BUTTON_ID).style.display = "";
}, WAIT_FOR_SECONDS*1000);
}
function _e(id) {
return document.getElementById(id);
}
