I'm building a custom slider on Javascript , and I want that every time the user clicks on a div of the slider, the slider should stop for X seconds.
My code is:
$(document).ready(function () {
var ciclo;
var index_slide = 1;
function startSlidercicle() {
ciclo = setInterval( function() {
// Slider code goes here
}, 3000);
}
//Here I start the slider animation
startSlidercicle();
//When the user clicks on a div called 'slide', stop the cycle and start again the animation cycle
$('.slide').on('click', function() {
clearInterval(ciclo);
setTimeout(startSlidercicle(), 3000);
});
});
But the problem is that everytime I click and stop the slider, the cycle starts faster and faster. How can I fix it?
Instead of:
clearInterval(ciclo);
setTimeout(startSlidercicle(), 3000);
or:
clearInterval(ciclo);
setTimeout(startSlidercicle, 3000);
I changed the code to be:
clearInterval(ciclo);
startSlidercicle();
And now the slider just works fine. I think that, in the first two proposals, every time I click on the div, a new function is created, "overlapping" over the existing cycle and, thus, it looks like the slider speeds up, but its just one cycle starting over another.
You need to change this:
clearInterval(ciclo);
setTimeout(startSlidercicle(), 3000);
to this:
clearInterval(ciclo);
setTimeout(startSlidercicle, 3000);
In your existing code, you are calling startSlidercirle immediately and it is not waiting until the setTimeout() fires because you have the () after the function name. That means to execute it immediately and pass the result of executing that to setTimeout(). You want to just pass the function reference to setTimeout() which is done by just having the name of the function with no () after it. This is a common mistake.

Simple question from a newbie:
How do I reset/restart a function after completing the time of (500
ms) in order to repeat the function each time I click on a specific
button?
FIRST PART OF THE CODE WORKS
my div is disappearing after 500ms fading out
$('.animate-this').click(function () {
$('p').show().delay(500).fadeOut();
});
SECOND PART IS MISSING
I would need to reset the fuction in order to repeated immediately...
I guess there is a very simple solution for that..
fadeOut accepts a callback function. You can use that
function animate() {
$('p').show().delay(500).fadeOut('slow', function() {
animate()
});
}
I am trying to create a front-end to a task management system, and I'm stuck on a setTimeout problem. I am trying to make it so that when a user clicks the checkbox, the tile fades to 33% opacity/toggle a "completed" class, waits 2 seconds, and then disappears; if the user clicks again on the checkbox before it disappears, the task should toggle the class and clear the timeout.
I am having a lot of trouble getting the clearTimeout command to work. I have declared my timer variable outside of the relevant blocks, tried adding the clearQueue() and stop() commands to my function, and triple-checked spelling.
My JS fiddle is here: http://jsfiddle.net/sLYA9/.
Here is my relevant JS:
$('#alltasks .taskitem form').click( function ( event ) {
event.preventDefault();
// Variables for different referenced elements
var tile = $( this ).parent('.taskitem');
var taskContents = '<div class=\'taskitem\' draggable=\'true\'>' + tile.html() + '</div>';
var timer;
// Unchecking a checked task
if (tile.hasClass('completed')) {
clearTimeout( timer );
tile.clearQueue().stop().fadeTo( 300, 1 );
} else { // Checking an unchecked task
tile.fadeTo( 300, 0.33 );
timer = setTimeout( function() {
alert("the task disappears");
}, 2000 );
}
tile.toggleClass('completed');
});
Again, I would like the user to be able to click the checkbox again before the 2000 ms timer is up and clear the timer.
Any ideas what I missed?
EDIT: I feel silly now. Moving my timer declaration outside of the click handler function made it work properly.
The scope of the timer is local so each time it is called you have a new scope.
The variable timer needs to be declared outside of the click function.
Your timer scoped in the first "click" function. If you move var timer outside of the click callback it works. You could just check when the timer fires to see if it is still "complete"
I create this function for show div with function call , but i nedd execute this function and stop in one second after show :
<script>
function repit_clouds(request)
{
if (request=='no')
{
stop();
}
else
{
if (request=='ok')
{
var interval = setInterval(function() {
$("#header_sun").fadeIn(4000);
$("#header_sun").fadeOut(4000);
},10000);
}
}
}
$(document).ready(function()
{
$("#header_sun").fadeIn(4000).delay(4000).fadeOut(4000);
repit_clouds('ok');
$("#header_background_clouds").fadeOut(2000).css("display","#none");
$("#header_background_night").fadeIn(2000).css("background","#000").show(4000).fadeIn(2500);
repit_clouds('no');
});
</script>
The problem it´s with repit_clouds function , when i send the value no the function must stop , but no works fine and continue as if the request==ok , i don´t know why no stop
umm, what exactly do you think stop() does? Did you perhaps mean:
$('#header_sun').stop()
which would pause any existing animations on that element?
Or did you perhaps also want to stop the interval timer:
clearInterval(interval);
which of course also requires that interval be declared outside of the function so that its value isn't lost each time you call the function.
I note also that your .css() functions won't be queued by the .fadeOut() or .show() calls - .css() isn't an animation function so those changes will always happen immediately.
Likewise the two calls to repit_clouds() won't be queued either - if you expect those to be done after the previous animations then you need to investigate the jQuery .queue() function, or trigger them during "animation complete callbacks".
I would like to set the jQuery Isotope shuffle method to to perform an animated shuffle of the loaded DOM elements every 30 seconds that someone is on the page with the plugin loaded.
I have had success tying the animation to a .hover() event, but I cannot seem to get it to fire when I use setInterval() or .queue(). I want the animation to fire regardless of user interaction/input.
var iso_shuffle = function() {
$('#isotope').isotope('shuffle');
}
setInterval(iso_shuffle(), 2500);
Why does the previous code not trigger the randomization, yet this does:
$('#isotope').hover(function() {
iso_shuffle()
});
Cheers
iso_shuffle() calls the function immediately. The function returns nothing. So your setInterval is actually doing the equivalent of:
setInterval(undefined, 2500);
You want to use the function name as the callback for setInterval:
setInterval(iso_shuffle, 2500);
You need to pass the function itself, not its return value:
setInterval(iso_shuffle, 2500);
I have a popup that is executed on mouseover with jquery.
Within that function I have a second delay before the popup displays using settimeout
Problem is if in that second they mouse over multiple times then multiple popups are triggered.
$('#div').mouseover(function() {setTimeout("popup()",1000);});
What I need to do is disable the detection and then re enable it in popup().
How might I do that?
You can use .hover() with a clearTimeout(), like this:
$('#div').hover(function() {
$.data(this, 'timer', setTimeout(popup, 1000));
}, function() {
clearTimeout($.data(this, 'timer'));
});
This clears the timeout you're setting if the mouse leaves, you'll have to stay on the element for a full second for the popup to trigger. We're just using $.data() on the element to store the timer ID (so we know what to clear). The other change is to not pass a string to setTimeout() but rather a reference directly to the function.
I guess something like this
(function(){
var popup_timer = 0;
$('#div').mouseover(function() {
clearTimeout(popup_timer);
popup_timer = setTimeout("popup()",1000);
});
});
EDIT updated code, clearTimeout added, wrapped
