Need to have the below code work every 5 second instead of every button click (language: html):
<script>
function goFwd(e) {
reset();
if (e.target.classList.contains("next") && currentImage < thumbnails.length-1) {
currentImage += 1;
fullSizeImgs[currentImage].classList.add('show');
caption.textContent = thumbnails[currentImage].firstElementChild.getAttribute('alt');
hiLiteThumbnail();
} else if (e.target.classList.contains("next") && currentImage === thumbnails.length-1) {
currentImage = 0;
fullSizeImgs[currentImage].classList.add('show');
caption.textContent = thumbnails[currentImage].firstElementChild.getAttribute('alt');
hiLiteThumbnail();
}
}
</script>
You can use javascript to make the loop with 5 seconds.
<script>
window.setInterval(function(){
goFwd(e)
}, 5000);
</script>
when you want to stop the loop you can use: clearInterval()
Updated
You can make the button auto click after 5 seconds. Then your function will call automatically after every 5 seconds.
<script>
var btn = document.getElementById('your_button_id');
setInterval(function(){
btn.click();
}, 5000); // this will make it click again every 5 seconds
</script>

I am using this function to auto-click a button after 15 seconds. The problem is the user doesn't leave the page after the option is run and it may be re-run again on the same page but the timer continues. In fact, the timer continues even if I do the action myself.
<script type="text/javascript">
time = 15;
interval = setInterval(function() {
time--;
document.getElementById('Label1').innerHTML = "You must choose in " + time + " seconds"
if (time == 0) {
// stop timer
clearInterval(interval);
// click
document.getElementById('thebutton').click();
}
}, 1000)
</script>
So this script should run the timer and "press" the "thebutton" in fifteen seconds and then the timer should stop counting and reset until run again. If the button is pressed manually before 15 seconds it should still reset.
<input type='submit' id='thebutton' value='Done'></input>
Hopefully this is clear. I am still new and learning.
Set a base time and then reset it to that.
<script type="text/javascript">
time = 15;
baseTime = 15;
interval = setInterval(function() {
time--;
document.getElementById('Label1').innerHTML = "You must choose in " + time + " seconds"
if (time == 0) {
// stop timer
clearInterval(interval);
// click
document.getElementById('thebutton').click();
time = baseTime;
return false;
}
}, 1000)
</script>
I had a look at the code and the most critical thing that I think you should look at is that the button has no "onclick" function.
This means that clicking the button does nothing because you have not put a function there that does something when you click it.
I wrote some code that I hope helps:
let time = 15;
const label = document.getElementById("Label1");
const button = document.getElementById("thebutton");
const getText = () => `You must choose in ${time} seconds`;
const interval = setInterval(() => {
time--;
label.innerHTML = getText();
if (time === 0) {
// stop timer
clearInterval(interval);
// click
button.click();
}
}, 1000);
const stopTime = () => {
clearInterval(interval);
time = 15;
label.innerHTML = getText();
};
And in your html something like this:
<input type='submit' id='thebutton' value='Done' onclick="stopTime()" />
Finally I made a small video where I walk through the code, it could be useful as well: https://youtu.be/ZYS9AcxO3d4
Have a great day!
If you only want the button to be clicked once after 15 seconds then you should use the setTimeout() function instead of setInterval().
Then if you do not want the auto-click to happen if the user clicks the button then you would need to add an onClick handler to your button that calls clearTimeout().
I assume you want the label updated as the seconds count down? And it's unclear how the timer is started. Check the below code and see if it does what you expect.
var time, interval;
function stopTimer() {
if (interval) {
clearInterval(interval);
interval = null;
}
time = 15;
}
function timerAction() {
$('#lblStatus').text("You must choose in " + time + " seconds");
if (time-- <= 0) {
stopTimer();
console.log("done!");
$("#btnStop").click();
}
}
function startTimer() {
stopTimer();
timerAction();
interval = setInterval(timerAction, 1000);
}
$("#btnStart").click(function() {
startTimer();
});
$("#btnStop").click(function() {
stopTimer();
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<span id=lblStatus></span>
<button id='btnStart'>Reset / Start</button>
<button id='btnStop'>Stop</button>
If you want to run only once, you can use setTimeout function
setTimeout(your code, 15000);
I'm trying to make my code click a button and reload the page in Javascript. The button must be clicked 10 times every .5 seconds. When it's been clicked 10 times, I want the code to reload the page. Here's what I've got:
var rolls = 10
var q = 0
setInterval(
function() {
document.getElementById("roll").click();
q += 1
}, 500);
if (q == rolls) {
location.reload(true)
}
The following solution uses setInterval to click on the button and decreases rolls. If rolls reaches 0, then the page is reloaded. Your mistake was that your code which checked for the value of rolls ran just after the setInterval, earlier than it actually became 0.
var rolls = 10;
setInterval(
function() {
if (!(rolls--)) {
window.location.href = window.location.href;
}
document.getElementById("roll").click();
}, 500);
Try to insert the checking into the setInterval method:
var rolls = 10
var q = 0
setInterval(
function() {
document.getElementById("roll").click();
q += 1
if (q == rolls) {
location.reload(true);
}
}, 500);
you're doing the check just at the time you define the interval, so
if (q == rolls) {
location.reload(true)
}
is being called just once at the start.
put it inside the interval function like this:
setInterval(
function() {
document.getElementById("roll").click();
if (++q >= rolls) location.reload(true)
}, 500);
I'm trying to have, on a registered.php page, a countdown that shows a timer that starts from 3 secs and goes down second by second, redirecting to another page in the end.
However, when I load the page in my browser i'm redirected to the other page in an instant. Can someone help me figure out why?
The registration was successful, you will be redirected in <span id="num"></span> seconds.
<script>
$(document).ready(function (){
for (var i = 3; i>0; i--) {
setTimeout(function () {
$("#num").html(i);
},1000);
}
window.location.replace("login.html");
});
</script>
Since this is a redirection page, you might not want to include the whole jQuery library for this bit of code:
var remaining = 3;
function countdown() {
document.getElementById('num').innerHTML = remaining;
if (!remaining--) {
window.location.replace("login.html");
}
setTimeout(countdown, 1000);
}
window.onload = countdown;
JS Fiddle Demo
Proper way:
$(document).ready(function () {
var i = 3;
$("#num").html(i);
setInterval(function () {
if(i==0){window.location.replace("login.html");}
i--;
$("#num").html(i > -1 ? i : 0);
}, 1000);
});
setInterval would execute every second the function, but with the code you had, you just set setTimeout to execute after a second, but it didn't stop you from looping further. So you immediately had three timeouts set and then redirected.
$(document).ready(function () {
var timer = 3;
var clearTime = setInterval(function(){
$("#num").html(timer--);
if(timer == 0){
window.clearInterval(clearTime);
window.location.replace("login.html");
}
},1000);
});
I currently have a timer , that counts down from 2 minutes.
what I would like to happen is when the button is clicked, it is hidden until the timer runs out and when the timer runs out it is visible/clickable again. I would also like the timer to be hidden until the button is clicked, to be visible when the button is clicked and then to be hidden once the timer runs out.
here is my code
js
function startTimer() {
userInput = 120;
if(userInput.length == 0){
alert("Please enter a value");
} else {
var numericExpression = /^[0-9]+$/;
function display( notifier, str ) {
document.getElementById(notifier).innerHTML = str;
}
function toMinuteAndSecond( x ) {
return Math.floor(x/60) + ":" + x%60;
}
function setTimer( remain, actions ) {
(function countdown() {
display("countdown", toMinuteAndSecond(remain));
actions[remain] && actions[remain]();
(remain -= 1) >= 0 && setTimeout(countdown, 1000);
})();
}
setTimer(userInput, {
0: function () { alert( "Time Is Up. Please Sumbit Vote."); }
});
}
}
html
<div id="countdown"></div>
<input type="button" onclick="startTimer()" value="Start Timer">

You can hide and unhide the button using JS
JSFiddle
Add an ID to your button
<input id="btn" type="button" onclick="startTimer()" value="Start Timer"/>
JScode
function startTimer() {
//hide button
document.getElementById("btn").style.display = "none";
//un-hide timer
document.getElementById("countdown").style.display = "inline";
userInput = 10;
if (userInput.length == 0) {
alert("Please enter a value");
} else {
var numericExpression = /^[0-9]+$/;
function display(notifier, str) {
document.getElementById(notifier).innerHTML = str;
}
function toMinuteAndSecond(x) {
return Math.floor(x / 60) + ":" + x % 60;
}
function setTimer(remain, actions) {
(function countdown() {
display("countdown", toMinuteAndSecond(remain));
actions[remain] && actions[remain]();
(remain -= 1) >= 0 && setTimeout(countdown, 1000);
})();
}
setTimer(userInput, {
0: function () {
alert("Time Is Up. Please Sumbit Vote.");
//un-hide button
document.getElementById("btn").style.display = "inline";
//hide timer
document.getElementById("countdown").style.display = "none";
}
});
}
}
Here is a fiddle with the solution:
Use the display property:
document.getElementById("button1").style.display="none";
and to show:
document.getElementById("button1").style.display="block";
fiddle
Make sure to add button1 as an id to your button:
<input id="button1" type="button" onclick="startTimer()"
The fiddle shows where you should put this code...
I went ahead and built it from scratch using JQuery as your friend suggested. I think all the answers here using your setTimeout are taking the wrong approach. This is more of a job for setInterval which will provide slightly less performance overhead and much cleaner code.
Working Example: http://codepen.io/Chevex/pen/RNomGG
First, some simple HTML to work with.
<div id="timerDisplay"></div>
<button id="startTimer">Start Timer</button>
Next, a simple timer script.
// Passing a function to $() is the same as $(document).on('ready', function () { ... });
// It waits for the entire page to be loaded before running the function, which is usually what you want.
$(function () {
// Get reference to our HTML elements and store them as variables.
// I prepend them with dollar signs to signify they represent HTML elements.
var $startTimer = $('#startTimer');
var $timerDisplay = $('#timerDisplay');
// The initial time of the timer.
var time = 120;
// Hide the timer display for now, until the button is clicked.
$timerDisplay.hide();
// Set up a click handler on our $startTimer button.
$startTimer.click(function () {
// When the button is clicked, do the following:
// Set the disabled property to true for our button.
// Effectively the same as <button id="startTimer" disabled>Start Timer</button>
$startTimer.prop('disabled', true);
// Fade in our timer display DIV element.
$timerDisplay.fadeIn();
// Set a timeRemaining variable to the value of the initial time.
var timeRemaining = time;
// Declare an interval function that runs every second.
// Also get reference to the intervalId that it returns so we can kill it later.
var intervalId = setInterval(function () {
// Every time the interval runs (every second), do the following:
// Create a formatted countdown timestamp using the timeRemaining.
var timeStamp = Math.floor(timeRemaining/60) + ':' + timeRemaining%60;
// Set the text of our timer display DIV element to our formatted timestamp.
$timerDisplay.text(timeStamp);
// If the timeRemaining is zero, clean up.
if (timeRemaining === 0) {
// Kill the interval function so it doesn't run again.
clearInterval(intervalId);
// Fade out our timer display DIV element.
$timerDisplay.fadeOut();
// Show the alert informing the user the timer is up.
alert('Time is up, please submit a vote :)');
// Re-enable the startTimer button.
$startTimer.prop('disabled', false);
}
// Otherwise subtract one second from the timeRemaining and allow the interval to continue.
else {
timeRemaining--;
}
}, 1000);
});
});
I want my trigger to activate every 2 seconds, but each time with my value of i.
Like first 3 seconds trigger .slide1, after another 3 seconds .slide2 etc...
Here my code :
setInterval(function () {
for ( var i = 0; i < 5; i++ ) {
$('.slide'+ i).trigger('click');
}
}, 3000)
After 3 seconds it immediately trigger my .slide4 and i was wondering why ?
Try
var slide = 0;
setInterval(function () {
$('.slide'+ (slide++ % 5)).trigger('click');
}, 3000);
The problem with your code is that each time the interval function is called, you execute the loop and trigger the click event for all the slides.
