I have a question about my code. What I'm trying to do is if a certain button is clicked and it isn't clicked again within 4 seconds, a element will be showed and another element hide. But if it is clicked within 4 seconds, it stays the same and so on. I think I should use SetInterval() and ClearInterval(). Currently I have two other functions that do other things. Maybe I can my function there?
Hopefully I have made it clear.
Current javascript code:
var clicks = 0;
function clicks5times() {
clicks = clicks+1;
if(clicks == 6){
document.getElementById('scherm3').style.display = 'block';
document.getElementById('scherm2.2').style.display = 'none';
}
}
var clicked = false;
setInterval(function(){
if (!clicked) {
document.getElementById("scherm4").style.visibility = "visible";
document.getElementById("scherm2.2").style.visibility = "hidden";
}
},13000);
document.getElementById("buttontimer").addEventListener("click", function(){
clicked = true;
});
Rather than set interval, I would say a timer would be better. Eg:
var clickTimer;
function startTimer() {
clickTimer = window.setTimeout(function(){
document.getElementById("scherm4").style.visibility = "visible";
document.getElementById("scherm2.2").style.visibility = "hidden";
},4000);
}
function stopTimer() {
window.clearTimeout(clickTimer);
}
function restartTimer() {
stopTimer();
startTimer();
}
document.getElementById("buttontimer").addEventListener("click", function(){
restartTimer();
});
This way when you want to stop the timer or start the timer, you have to just call above functions for other scenarios.
eg:
If you have an init function:
function init() {
...
//some code
startTimer();
}
And maybe call stop timer like so:
function clicks5times() {
...
stopTimer();
}
Split your event handlers in two different functions (eg firstClick and secondClick). The first handler should just add a second event listener and remove it after 4 seconds. For this one-off task, use setTimeout instead of setInterval as you need the task to be done only once after 4 seconds and not every 4 seconds. So I would proceed as follows:
var secondClick = function() {
// DO WHATEVER YOU WANT TO HAPPEN AFTER THE SECOND CLICK
}
var firstClick = function() {
// DO WHATEVER YOU WANT TO HAPPEN AFTER THE FIRST CLICK
document.getElementById("buttontimer").addEventListener("click", secondClick);
setTimeout(function() {
document.getElementById("buttontimer").removeEventListener("click", secondClick);
}, 4000);
};
buttonElement.addEventListener("click", firstClick);

<button id='action'>Hello</button>
I'm trying to alert Click if i just clicked on the button, And alert Hold if i hold clicking the button for 2s,
The problem is that it always alerts Hold after clicking.
How to fix that And how to count the time of holding the button exactly?
Try the snippet below:
$(document).ready(function() {
var timeoutId = 0;
var functionCalled = false;
$("#btn").on("mousedown", function() {
timeoutId = setTimeout(btnHeld, 2000);
}).bind("mouseup", function(e) {
if (!functionCalled) {
alert('clicked');
}
functionCalled = false;
clearTimeout(timeoutId);
});
function btnHeld() {
functionCalled = true;
alert("hold");
}
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<button id="btn">click</button>
You need to handle the mousedown event, set a timer for two seconds, then cancel that timer in the mouseup event.
I would like to hide and then show the "Reset" button as soon as the counter reaches zero.

AWolf's answer is a bit fancier than mine, and they made some good points about your code, but I tried to keep mine simple and tried not to change your original code too much.
Your init() function will now hide the Reset button, and I had the update_target() function show the Reset button when the timer expired.
Fiddle: http://jsfiddle.net/rgutierrez1014/o4ak8wzs/4/
In this jsFiddle you'll find the updated code and how you could add that behaviour.
I've also improved your code a bit. It's easier to write Countdown.prototype = { init: function() {...}, ...} then writing Countdown.prototype.init = function() {...}
I also changed your setInterval to setTimeout and start a new timeout every second. That's easier and you don't need to clear the interval at the end. Also the callback function for your interval seemed a bit strange and that probably won't work.
You could add your click handlers in the init method of your countdown object like this $('#start').click(this.start.bind(this)); the .bind(this) is used to change the context inside the click handler to the currently used object. Then this inside of the handler is your object and you can access everything with this.
To hide the reset button at start I've used the css display: none; and if you are at zero then show the button with $('#reset').fadeIn('slow'); or $('#reset').show(); if you don't want the animation.
Update 13.03.2015
As mentioned in the comments I've improved the code and now I'm using a jQuery Countdown plugin.
Please have a look at the latest version in this jsFiddle.
I think it's much better then the other code.
(function () {
function Countdown() {
this.start_time = "00:30";
this.target_id = "#timer";
//this.name = "timer";
}
Countdown.prototype = {
init: function () {
console.log('init called');
this.reset();
$('#start').click(this.start.bind(this));
$('#reset').click(this.reset.bind(this));
},
reset: function () {
time = this.start_time.split(":");
//this.minutes = parseInt(time[0]);
this.seconds = parseInt(time[1]);
this.update_target();
},
tick: function () {
if (this.seconds > 0) //|| this.minutes > 0)
{
if (this.seconds == 0) {
// this.minutes = this.minutes - 1;
this.seconds = 59
} else {
this.seconds = this.seconds - 1;
}
this.start();
}
else {
// show reset button
$('#reset').fadeIn('slow');
}
this.update_target();
},
start: function() {
console.log('start called');
//setTimeout(this.name + '.tick()', 1000);
setTimeout(this.tick.bind(this), 1000);
},
update_target: function () {
seconds = this.seconds;
if (seconds < 10) seconds = "" + seconds;
$(this.target_id).val(this.seconds);
}
};
var counter = new Countdown();
counter.init();
})();
#reset {
display: none;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="text" id="timer">
<button id="start">Start</button>
<button id="reset">Reset</button>
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' />
This is my code. Here the div is animated after 5 sec and hidden after another 5 sec. I need to repeat this every 5 sec. That means every 5 second the div will animate and disappear after another 5 second.

You could use the setInterval() method in javascript.
Summary
Calls a function or executes a code snippet repeatedly, with a fixed
time delay between each call to that function.
MDN Documentation
I've just wrapped your code in the "fader" function, then on document load, setInterval will run every 10 seconds.
<script>
function fader () {
$('#div').delay(5000).fadeIn(function() {
$(this).text('Some other text!').css({'text-align':'center',})
});
$("#div").animate({
left:'450px',
opacity:'0.5',
height:'250px',
width:'250px',
border:'3px solid',
borderColor: 'darkolivegreen',
backgroundColor: '#cccc'
})
$('#div').delay(5000).fadeOut();
};
$(function () {
setInterval(fader,10000);
})
</script>
<div id="blinkText"></div>
<script>
// Takes text to blink and id of element to blink text in
function blinkText(text, id) {
// Blink interval
setInterval(blinker, 5000);
// Flag to see what state text is in (true or false)
var flag = true;
// Number of times to blink text
var blinkNum = 10000;
var i = 1;
//you can select whole div by ajax
var divID = document.getElementById(id);
function blinker() {
if (i < blinkNum) {
if (flag) {
divID.innerHTML = text;
flag = false;
} else {
divID.innerHTML = "";
flag = true;
}
i++;
} else {
// Delete if it's still showing
divID.innerHTML = "";
// Stop blinking
clearInterval(blinker);
}
}
}
blinkText("Hello World", "blinkText");

I want to stop my javascript after x seconds, I saw that the function is setTimeout, I tried to add that to my code but no succes, is this the better way to do this?
Thanks for your help !
<html>
<head>
<script type="text/javascript">
function blink(){
state = document.getElementsByTagName('img')[0].style.visibility;
if(state == 'hidden'){
newState = 'visible';
}else if(state == 'visible'){
newState = 'hidden';
}
document.getElementsByTagName('img')[0].style.visibility = newState;
}
setInterval('blink();', 300);
</script>
</head>

Initialize your interval in a variable and clear it after X (here 2) seconds:
var interval = setInterval(blink, 300);
setTimeout(function() {
clearInterval(interval);
}, 2000);
use like this:
var myvar;
function myStartFunction()
{
myvar=setInterval(function(){blink()},300);
}
function myStopFunction()
{
clearInterval(myvar);
}
