window.onhashchange = function () {
window.setTimeout(function () {
let frame = document.querySelector("body > iframe");
if (frame !== null) {frame.replaceWith(frame);}
}, 1000);
}
//reload the iframe
var i = 0;
while (i < 100) {
async function DStuff(){
await document.querySelector("#Btn").click()
}
setTimeout(() => { DStuff() }, 3000)
window.onhashchange();
i++;
}
//click button
I want to refresh iframe and click button as much as I want. When I run this script it doesn't loop. Also the script should wait for a second after click the button.
Drop the loop and simply use a setInterval:
window.onhashchange = function () {
window.setTimeout(function () {
let frame = document.querySelector("body > iframe");
if (frame !== null) {frame.replaceWith(frame);}
}, 1000);
}
//reload the iframe
var i = 0;
let myVar = setInterval(function(){
i++;
document.querySelector("#Btn").click();
window.onhashchange();
if (i === 100) {
clearInterval(myVar);
}
},3000);
The above waits for 3 seconds until it clicks again while it stops after reaching 100 clicks.
Needless to say, the iFrame must be on the same domain, otherwise it won't be accessible due to cross-site restriction.
If you want to use a different time delay between the reload and the click, you can use two functions that recursively call each other, with a count to stop the loop:
var totalIterations = 0;
function clickButton() {
console.log("clickButton called")
// Your Click-button code here
//document.querySelector("#Btn").click()
// In 1 second, call the reload frame function
setTimeout(reloadFrame, 1000)
}
function reloadFrame() {
console.log("reloadFrame called")
// Your Reload-frame code here:
//let frame = document.querySelector("body > iframe");
//if (frame !== null) { frame.replaceWith(frame); }
// If we haven't run 100 times yet, run the click button in 3 seconds
if (totalIterations < 100) {
setTimeout(clickButton, 3000)
totalIterations++
}
}
// Call the function to start
clickButton()

What I want:
There are two pictures that are being switched/swapped every three seconds.
I want to make it so that when the button is clicked, the picture switches and the auto-swap resets. So if the button is clicked, the image swaps and three seconds later, it will auto-swap, until the button is clicked again in which the cycle will repeat.
What I have right now
Currently, the problem is that: when the button is clicked, it messes up the timing of the auto-switches.
Edit:
Please don't create a new code base. Just modify mines. The code doesn't have to be an expert super concise level. I'm only three weeks into JavaScript (and it's my first programming language). I have to explain to classmates and it wouldn't be nice the code had elements I don't understand. So sorry for the inconvenience.
Right now I just need the button to correctly stop and restart the time.

The reason why your timer resets is because you are not clearing the timeout.
you need to make a reference to the timeout and then use clearTimeout() on it whne you make the fast change. I don't think it is possible or wise to do that inline the way you have it so you code needs to be refactored
let imgSrc1 = 'https://images.pexels.com/photos/248797/pexels-photo-248797.jpeg?auto=compress&cs=tinysrgb&h=350'
let imgSrc2 = 'https://images.pexels.com/photos/67636/rose-blue-flower-rose-blooms-67636.jpeg?auto=compress&cs=tinysrgb&h=350'
let imgElement = document.getElementById('picture');
let timeout;
function change() {
if(imgElement.src === imgSrc1) {
imgElement.src = imgSrc2;
} else {
imgElement.src = imgSrc1;
}
if (timeout) {
clearTimeout(timeout);
}
timeout = setTimeout(change, 3000);
}
You don't even need the second function fastChange. Now you can sent the onClick listener to change() like this
document.getElementById('whatever you want to click').onCLick = change;
Setting and clearing timeouts in multiple places will work, but I prefer using a "main loop" and a variable to count frames.
Here's an example that uses setInterval and resets a timer variable when the button was clicked:
const url1 = "https://images.pexels.com/photos/248797/pexels-photo-248797.jpeg?auto=compress&cs=tinysrgb&h=350";
const url2 = "https://images.pexels.com/photos/67636/rose-blue-flower-rose-blooms-67636.jpeg?auto=compress&cs=tinysrgb&h=350";
function change() {
picture.src = picture.src == url1 ? url2 : url1;
}
var timer = 0;
setInterval(function() {
timer++;
time.textContent = timer;
if (timer === 30) fastChange();
}, 100);
function fastChange() {
change();
timer = 0;
}
picture.src = url1;
swap.onclick = fastChange;
#picture {
height: 70vh
}
<button id="swap">SWAP</button> <span id="time"></span><br>
<img id="picture">
You can do this by calling setTimeout and updating the index as necessary. Just be sure to store the most recent timeout id so that it can be cancelled on reset using clearTimeout.
// store the reference to the <img> that contains the picture
const pic = document.getElementById('picture')
// store a list (array) of the two picture urls
const sources = [
'https://images.pexels.com/photos/248797/pexels-photo-248797.jpeg?auto=compress&cs=tinysrgb&h=350',
'https://images.pexels.com/photos/67636/rose-blue-flower-rose-blooms-67636.jpeg?auto=compress&cs=tinysrgb&h=350'
]
// used to store a reference to the interval timer you created.
var lastTimer
// a starting index of the list (i.e. which image we are up to right now)
var index = 1
// this functions swaps the image and sets a timer
function startRotation() {
// update the index to the next one (goes 0-1-0-1->etc)
index = 1 - index
// sets the .src of the image element
pic.src = sources[index]
// starts a 3 second timer to call this same function again
// but also stores a reference to the timer so that it can be cancelled
lastTimer = setTimeout(startRotation, 3000)
}
// this functions resets the timer and restarts the process
function reset() {
// stop the current timer if there is one
if(lastTimer){
clearTimeout(lastTimer)
}
// restart the process
startRotation()
}
// start the swapping process on start
startRotation()

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.
this is the code that comes in head section and it will automatically refresh the whole page in 1 min as i put 6000 in the code below
<script type="text/javascript">
setTimeout('window.location.href=window.location.href;', 6000);
</script>
is there any way for example, when there's 10 seconds left to refresh the page then, a button will display and say "Click here to reset timer" and it will reset that timer to 1 min again?
<script language="javascript">
var timeout,interval
var threshold = 15000;
var secondsleft=threshold;
startschedule();
window.onload = function()
{
startschedule();
}
function startChecking()
{
secondsleft-=1000;
if(secondsleft <= 10000)
{
document.getElementById("clickme").style.display="";
document.getElementById("timercounter").innerHTML = Math.abs((secondsleft/1000))+" secs";
}
}
function startschedule()
{
clearInterval(timeout);
clearInterval(interval);
timeout = setTimeout('window.location.href=window.location.href;', threshold);
secondsleft=threshold;
interval = setInterval(function()
{
startChecking();
},1000)
}
function resetTimer()
{
startschedule();
document.getElementById("clickme").style.display="none";
document.getElementById("timercounter").innerHTML="";
}
</script>
Please wait...<span id="timercounter"></span>
<button id="clickme" style="display:none;" onclick="javascript:resetTimer();">Click here to reset timer</button>
Assuming you have the following html for the button:
<button id="cancel-reload-button" style="display: none" onclick="cancelReload()">Cancel Reload</button>
And this as the script (Note: this gives the idea, but is not neccesarily fully tested):
// Variable for holding the reference to the current timeout
var myTimeout;
// Starts the reload, called when the page is loaded.
function startReload() {
myTimeout = setTimeout(function() {
document.getElementByID("cancel-reload-button").style.display = "inline";
myTimeout = setTimeout(function() {
window.location.reload();
} 10000)
}, 50000);
}
// Cancel the reload and start it over. Called when the button is
// clicked.
function cancelReload() {
clearTimeout(myTimeout)
startReload()
}
// On page load call this function top begin.
startReload();
I created two functions, one for starting the reload and the second one for cancelling it.
Then I assigned the timeout to the variable myTimeout which can be used to later cancel the timeout.
Then I called myTimeout twice - Once for 50 secs, at which point it shows the button and once for 10 secs after which it finally reloads.
How about below? If you click on OK to reset timer, it would keep giving the confirm box every 50 seconds. If you click cancel, it will refresh the page in 10 seconds.
setInterval(function(){ var r = confirm("Reset Timer");
if (r == true) {
setTimeout('window.location.href=window.location.href;', 60000);
} else {
setTimeout('window.location.href=window.location.href;', 10000);
}
}, 50000);
Note: In your question you specified 1 minute, but your code works for 6 seconds(6000 -- > 6 seconds not 60 seconds) I have included for a minute
You can use 2 setTimeout calls, one to make the "Reset" button show up and another one for the refresh timer reset. The trick is to store the second setTimeout on a global variable and use clearTimeout to reset it if the button is pressed.
Here is some JavaScript code to illustrate:
<script type="text/javascript">
var autoRefreshTime = 30 * 1000; // 60000ms = 60secs = 1 min
var warningTime = autoRefreshTime - (10 * 1000); // 10 secs before autoRefreshTime
waitTimeout = setTimeout('window.location.href=window.location.href;', autoRefreshTime);
warningTimeout = setTimeout('ShowResetButton();', warningTime);
function ShowResetButton() {
// Code to make the "Reset" button show up
}
// Make this function your button's onClick handler
function ResetAutoRefreshTimer() {
clearTimeout(waitTimeout);
waitTimeout = setTimeout('window.location.href=window.location.href;', autoRefreshTime);
}
</script>
The way I would do it is make a function with a timeout, and invoke that function
<script type="text/javascript">
var refreshFunc = function(){
setTimeout(function(){
var r = confirm("Do you want to reset the timer?");
if(r === false){
window.location.href=window.location.href;
}else{
refreshFunc();
}
}, 6000);
};
refreshFunc();
</script>
One big problem with using confirm in this case is you cannot program it to reject. You would have to implement you own modal/dialog box so you can auto reject in 10 seconds.
Try using setInterval():
var time;
$(function() {
time = $('#time');
$('#reset').on('click', reset);
start();
});
var timer, left;
var start = function() {
left = +(time.text()); //parsing
timer = setInterval(function() {
if (0 <= left) {
time.text(left--);
} else {
clearInterval(timer);
location.replace(location);
}
}, 1000);
};
var reset = function() {
if (timer) {
clearInterval(timer);
}
time.text('59');
start();
};
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<h1><span id='time'>59</span> second(s) left</h1>
<input id='reset' value='Reset' type='button' />
i currently am using the below javascript code below,
<script type="text/javascript">
function PrintWindow()
{
window.print();
CheckWindowState();
}
function CheckWindowState()
{
if(document.readyState=="complete")
{
window.close();
}
else
{
setTimeout("CheckWindowState()", 2000)
}
}
PrintWindow();
//window.onfocus = function() { window.close(); }
// Trying to auto refresh the page after 3 seconds of no use.
function setIdle(cb, seconds) {
var timer;
var interval = seconds * 1000;
function refresh() {
clearInterval(timer);
timer = setTimeout(cb, interval);
};
$(document).on('keypress, click', refresh);
refresh();
}
setIdle(function() {
location.href = location.href;
}, 3);
</script>
My original question was how to go home when the print box was finished but was told this was impossible, so i am now wondering how to auto refresh the page after so many seconds have passed, i have added in code to do this but it is not working
i have now managed to fix it, if any one is wondering :
var timer = null;
function goAway() {
clearTimeout(timer);
timer = setTimeout(function() {
window.location = 'http://localhost:8080/fileuploadWithPreview';
}, 5);
}
window.addEventListener('mousemove', goAway, true);
goAway(); // start the first timer off
This when the window is closed takes me to the home page so it is possible to do
I have a website which I would like to auto refresh ONLY if user is not using it for a specific time (ie.180 sec).Is there a way to auto refresh HTML only if there has been no activity on a page?
Thank you!
Two approaches:
1. Use a once-a-second timer and a "timeout" value.
You probably want to wrap this up in an object:
var activityHandler = (function() {
var timerHandle = 0,
timeout;
flagActivity();
function start() {
stop();
flagActivity();
timerHandle = setInterval(tick, 1000);
}
function stop() {
if (timerHandle != 0) {
clearInterval(timerHandle);
timerHandle = 0;
}
}
function flagActivity() {
timeout = new Date() + 180000;
}
function tick() {
if (new Date() > timeout) {
stop();
location.reload();
}
}
return {
start: start,
stop: stop,
flagActivity: flagActivity
};
})();
Then start it on page load:
activityHandler.start();
And ping it every time you see "activity":
activityHandler.flagActivity();
So for instance, you might do this:
if (document.addEventListener) {
document.addEventListener('mousemove', activityHandler.flagActivity, false);
}
else if (document.attachEvent) {
document.attachEvent('onmousemove', activityHandler.flagActivity);
}
else {
document.onmousemove = activityHandler.flagActivity;
}
2. Use a timer you reset every time there's "activity".
This is less ongoing work (we don't have something happening every second), but more work when you flag that activity has happened.
Set up a timer to do the refresh:
var handle = setTimeout(function() {
location.reload();
}, 180000);
...and then cancel and reschedule any time you see whatever you consider to be "activity":
clearTimeout(handle);
handle = setTimeout(...);
You can wrap this up in a function:
var inactivityTimerReset = (function() {
var handle = 0;
function reset() {
if (handle != 0) {
clearTimeout(handle);
}
handle = setTimeout(tick, 180000);
}
function tick() {
location.reload();
}
return reset;
})();
// Kick start
inactivityTimerReset();
// ...and anywhere you see what you consider to be activity, call it
// again
inactivityTimerReset();
Then, again, ping it on every activity. But this is a lot more work than I'd put in a mousemove handler, hence solution #1 above.
var docTimeOut;
function bodyTimeOut()
{
docTimeOut=setTimeout(function(){location.reload();},18000);
}
function resetTimeOut()
{
clearTimeout(docTimeOut);
bodyTimeOut();
}
document.onload = bodyTimeOut;
document.body.onmouseover= resetTimeOut;
you could declare a variable pageActive or something, set it to false, and whenever user does something set it to true.
Then, set a function to execute periodically as frequently as you want with setinterval() that checks this variable, if it's true set it to false to start again, if is false then refresh page.
You can use onblur and onfocus on body element to see if there is a kind of activity on your page.
