Im making a basic jQuery slider for class. and would like to have it autoplay playing the next slide after 5 seconds but haven't used the timer before it isn't doing what I thought it should do. It waits for the proper interval and then keeps triggering the callback function.
//basic slider on click
$('.slider>ul>li').click(function()
{
$('.slider>ul>li').removeClass('current');
$(this).toggleClass('current');
right=$(this).index()*745;
$(this).parent('ul').parent('.slider').children('div').children('ul').animate({'right': right}, 1000, 'easeOutBack');
})
//attempt to use timer plugin to auto play
$('.slider>ul>li').timer(
{
delay: 1000,
callback: function()
{alert($('.slider>ul>li.current').index())
if($('.slider>ul>li.current').index()!=3)
{
$('.slider>ul>li.current').next('li').click();
}else//oddly this doesn't trigger at all
{
$('.slider>ul').first().click();
}
}
})
Try this:
setInterval(function(){
var i = $('.slider>ul>li.current').index();
var next = (i < 3 ? i+1 : 0);
var items = $('.slider>ul>li');
$(items[next]).click();
}, 5000);
EDIT:
changed setTimeout to setInterval and bumped time to 5sec; this should now loop.

I have an tag that is having its contents changed via jquery and then faded in and out (using the velocity js library) utilizing the setInterval function. When I run this it tends to work fine for about 30 seconds before it starts to malfunction and jquery starts to change the contents of the tag before the tag has faded out.
Here is the Javascript code
let counter = 0;
function chooseWord() {
let words = ["foo", "bar", "foo"];
if (counter !== 2) {
counter += 1;
} else {
counter = 0;
}
return words[counter];
}
function refreshText() {
$("#div").text("Foo " + chooseWord())
.velocity("fadeIn", {
duration: 2500
})
.velocity("fadeOut", {
delay: 1500,
duration: 2500
});
}
$(document).ready(function() {
refreshText();
setInterval(function() {
refreshText();
}, 7000);
});
And here is my tag that is being used
<h1 class="foobar" id="div"></h1>
I've tried using Jquery's timer and I have the same issue. Does anyone know what the problem might be or maybe a different way of achieving what I want to do?
You just need to change the order of operations. I have moved the text-change command after fade-out. So the element fades out, and then jQuery will update its text.
$("#div")
.velocity("fadeIn", {
duration: 2500
})
.velocity("fadeOut", {
delay: 1500,
duration: 2500
})
.text("Foo " + chooseWord());

I have a three different transitions for fading out and fading in my 3 images.
animate1 = function() {
$('#changingImage').fadeOut('fast', function() {
$('#changingImage').attr("src","../files/others/image1.jpg");
$('#changingImage').fadeIn('fast');
});
};
I have this same function two more times, just replacing the 1s with 2s and 3s.
I call my three functions with this, repeating every 5 seconds:
animate1().delay(5000);
animate2().delay(10000);
animate3().delay(15000);
I'm new at jQuery, and I don't understand why the timing is wrong. All that happens is image2 (the original) gets replaced with image1, and that's it.
Try using the setTimeout() javascript function.
Documentation: http://www.w3schools.com/jsref/met_win_settimeout.asp
For example:
setTimeout(function(){ animate1(); }, 5000);
setTimeout(function(){ animate2(); }, 5000);
setTimeout(function(){ animate3(); }, 5000);
This basically 'pauses' your JavaScript/jQuery code for 5 seconds before running the function and continuing.
.delay() does not repeat an event, it just delays its execution. You need .setInterval() if you want to repeat an event based on a given interval:
window.setInterval(function(){
setTimeout(animate1, 1000);
setTimeout(animate2, 500);
}, 5000);

Yay! I figured it out with a bunch of help.
var animations = function() {
setTimeout(function() {
animate1();
console.log("Animation 1")
}, 5000);
setTimeout(function() {
animate2();
console.log("Animation 2")
}, 10000);
setTimeout(function() {
animate3();
console.log("Animation 3")
}, 15000);
};
setInterval(animations, 15000);
Hi i have a suggestion for you in case that you have more than this 3 image so you will create a new function for it ?
so what about to use only 1 function that will call it self with an attribute that define image name as it is the only thing is changing every time so you can use this better and less code ,you have just the n value will change every time will increase and the max value witch define how many image you want
//if you want to set this animation for more than 3 image just change the max value
var max=3;
setTimeout(function(){ animate(2); }, 5000);
animate = function(n) {
$('#changingImage').fadeOut('fast', function() {
if(n<=max){
$('#changingImage').attr("src","http://www.imacros-scripts-for-free.is-best.net/image"+n+".jpg");
$('#changingImage').fadeIn('fast');
if(n==max){n=1}else{n++;}
setTimeout(function(){ animate(n); }, 5000);
}
});
}

I have a fancybox for displaying photos and descriptions of them.
Now it opens fancybox on mouseenter event. It works perfectly with this code:
$('.fancy_link').live('mouseenter', mouseEnter);
function mouseEnter()
{
jQuery(this).fancybox().trigger('click');
return false;
}
But i need to set delay for opening fancybox. How it should work: User moves cursor over a link, after 1 second fancybox should open and display content. If user moves mouse away before waiting 1 second, fancybox should not open.
I have tried JQuery delay() and setTimeout() but both of them are not working properly.
One sec. delay just ignored by both methods.
use setTimeout/clearTimeout...
//binding code...
$('.fancy_link').on('mouseenter',mouseEnter);
$('.fancy_link').on('mouseleave', mouseLeave);
//run when the mouse hovers over the item
function mouseEnter() {
//clear any previous timer
clearTimeout($(this).data('h_hover'));
//get a reference to the current item, for the setTimeout callback
var that = this;
//set a timer, and save the reference to g_hover
var h_hover = setTimeout(function(){
//timer timed out - click the item being hovered
$(that).click();
}, 1000);
//save the reference - attached to the item - for clearing
// data is a generic "store", it isn't saved to the tag in the dom.
// note: if you have a data-* attribute it is readable via data()
$(this).data('h_hover',h_hover)
}
//handler for when the mouse leaves the item
function mouseLeave() {
//clear the previously set timeout
clearTimeout($(this).data('h_hover'));
}
this could help you
function openFancybox() {
setTimeout( function() {$('#fancy_link').trigger('click'); },1000);
}
I imagine you will need to use setTimeout and clearTimeout
Something along these lines:
var timer;
$('.fancy_link').mouseenter(function(){
var $this = $(this);
timer = setTimeout(function(){
$this.fancybox().trigger('click');
}, 1000);
}).mouseleave(function(){
clearTimeout(timer);
});
Try this solution:
var timer = null;
$('.fancy_link').on('mouseenter', function() {
timer = setTimeout(mouseEnter, 1000);
});
// clear timer when mouse leaves
$('.fancy_link').on('mouseleave', function() {
clearTimeout(timer);
});
I'm am attempting to build a homepage that has animations. I am having hard time controlling my animations though. All I need is to hide elements, and then show elements after a certain time. Loop through that sequence, and pause and show all elements when the someone hovers over the box. Example simple animation.
I have a long way to go. At first I tried using the .css() visibility property, now I'm using .show() and .hide().
I need a way to loop through my animations. I attempt to add another
setTimeout(clear1(), 3000);
to the end of my box1 function, but that wouldn't work for some reason.
I need a way to on a user hover over #box1, that all animations stop. I have tried using .clearQueue, but I couldn't get that to work.
First of all, set to your css:
.box {display: none;}
SHOW ALL BOXES ON HOVER See Demo
This will show all boxes on hover and then continue the animation from where it stopped (will hide the boxes that hadn't shown up during the animation). I think that is what you are after.
var index = 0; // To keep track of the last div showed during animation
var time_of_delay = 1000; // Set the time of delay
// Start the animation
$(document).ready(function () {
box1(time_of_delay);
});
// The hover states
$("#box1_1").hover(
function() {
box1(0);
}, function() {
box1(time_of_delay);
});
// The animation function
function box1 (delay_time) {
var time=delay_time;
if(time>0) {
$(".box").slice(index).each(function() {
$(this).hide().delay(time).show(0);
time=time+time_of_delay;
});
index=0;
} else {
$(".box:visible").each(function() {
index++;
});
$(".box").stop(true).show(0);
}
}
PAUSE ON HOVER See Demo
This will only pause the animation and continue from where it stopped.
var time_of_delay = 1000; // Set the time of delay
// Start the animation
$(document).ready(function () {
box1(time_of_delay);
});
// The hover states
$("#box1_1").hover(
function() {
box1(0);
}, function() {
box1(time_of_delay);
});
// The animation function
function box1 (delay_time) {
var time=delay_time;
if(time>0) {
$(".box:hidden").each(function() {
$(this).delay(time).show(0);
time=time+time_of_delay;
});
} else {
$(".box").stop(true);
}
}
I used setTimeout and clearTimeout and periodically call a function that increments (and resets) the box to display. Since I assign setTimout to boxt, I am able to call clearTimeout(boxt) on box1's hover event so that I can stop specifically that loop. Here's my jsfiddle. It might not be the exact effect you're trying to achieve, but it should be the right functionality and be easily adaptable with a few tweaks. Let me know if this works for you and if you have any questions about how it works :)
LIVE DEMO
var $box = $('#box1').find('.box'),
boxN = $box.length,
c = 0,
intv;
$box.eq(c).show(); // Show initially the '0' indexed .box (first one)
function loop(){
intv = setInterval(function(){
$box.eq(++c%boxN).fadeTo(400,1).siblings().fadeTo(400,0);
},1000);
}
loop(); // Start your loop
$('#box1').on('mouseenter mouseleave', function( e ){
return e.type=='mouseenter' ? (clearInterval(intv))($box.fadeTo(400,1)) : loop();
});
Where ++c%boxN will take care to loop your animation using the Modulo % (reminder) operator inside a setInterval. Than all you need to do is to register a mouseenter and mouseleave on the parent element to:
clear the Interval on mouseenter + fade all your elements
restart your loop function on mouseleave.
Here's one way to do it:
// hide all of the boxes
$('.box').hide();
// reference to each box, the current box in this list and a flag to stop the animation
var divs = box1.getElementsByClassName('box');
var i = 0;
var run = true;
// this will animate each box one after the other
function fade(){
if(i < divs.length && run){
$(divs[i++]).fadeIn(500, function(){
setTimeout(fade, 1000);
});
}
};
fade();
// stop the above function from running when the mouse enters `box1`
$('#box1').on('mouseenter', function(){console.log('enter');
run = false;
});
// start the function again from where we stopped it when the mouse leaves `box1`
$('#box1').on('mouseleave', function(){console.log('leave');
run = true;
fade();
});

I am working on a nested menu, and when my mouse move over a option, a sublist will show up.
Here is my hover function:
$( ".sublist" ).parent().hover( function () {
$(this).toggleClass("li_hover",300); //use to change the background color
$(this).find(".sublist").toggle("slide", {}, 500); //sub list show / hide
});
Now, I want add a short period before the sublist shows up to prevent the crazy mouse moving from user. Does somebody have a good suggestion on this?
Update:
Thanks for you guys, I did a little bit change on my program, recently it looks like this:
function doSomething_hover (ele) {
ele.toggleClass("li_hover",300);
ele.find(".sublist").toggle("slide", {}, 500);
}
$(function () {
$( ".sublist" ).parent().hover( function () {
setTimeout(doSomething_hover($(this)), 3000);
});
}):
This is weird that setTimeout will not delay anything. but if I change the function call to doSomething_hover (without "()"), the function will delay good. but i can not pass any jquery element to the function, so it still not works, could somebody tell me that how to make doSomething_hover($(this)) work in setTimeout ?
Update 2:
Got the setTimeout work, but it seems not what I want:
What I exactly want is nothing will happen, if the mouse hover on a option less than 0.5sec.
Anyway, here is the code I make setTimeout work:
function doSomething_hover (ele) {
ele.toggleClass("li_hover",300);
ele.find(".sublist").toggle("slide", {}, 500);
}
$(function () {
$( ".sublist" ).parent().hover( function () {
var e = $(this);
setTimeout(function () { doSomething_hover(e); }, 1000);
});
}):
Final Update:
I got this work by using clearTimeout when I move the mouse out.
so the code should be:
$( ".sublist" ).parent().mouseover( function () {
var e = $(this);
this.timer = setTimeout(function () { doSomething_hover(e); }, 500);
});
$( ".sublist" ).parent().mouseout ( function () {
if(this.timer){
clearTimeout(this.timer);
}
if($(this).hasClass("li_hover")){
$(this).toggleClass("li_hover");
}
$(this).find(".sublist").hide("slide", {}, 500);
});
This is the part in the $(document).ready(). Other code will be same as above.
真. Final Update:
So, mouseover and mouseout will lead to a bug sometime, since when I move the mouse to the sublist, the parents' mouseover event will be fire, and hide the sublist.
Problem could be solved by using hover function:
$( ".sublist" ).parent().hover(
function () {
var e = $(this);
this.timer = setTimeout(function () { doSomething_hover(e); }, 500);
},
function () {
if(this.timer){
clearTimeout(this.timer);
}
$(this).find(".sublist").hide("slide", {}, 500);
if($(this).hasClass("li_hover")){
$(this).toggleClass("li_hover",300);
}
}
);
Thanks all
Try this please:
Code
setInterval(doSomthing_hover, 1000);
function doSomthing_hover() {
$(".sublist").parent().hover(function() {
$(this).toggleClass("li_hover", 300); //use to change the background color
$(this).find(".sublist").toggle("slide", {}, 500); //sub list show / hide
});
}
SetTime vs setInterval
At a fundamental level it's important to understand how JavaScript timers work. Often times they behave unintuitively because of the single thread which they are in. Let's start by examining the three functions to which we have access that can construct and manipulate timers.
var id = setTimeout(fn, delay); - Initiates a single timer which will call the specified function after the delay. The function returns a unique ID with which the timer can be canceled at a later time.
var id = setInterval(fn, delay); - Similar to setTimeout but continually calls the function (with a delay every time) until it is canceled.
clearInterval(id);, clearTimeout(id); - Accepts a timer ID (returned by either of the aforementioned functions) and stops the timer callback from occurring.
In order to understand how the timers work internally there's one important concept that needs to be explored: timer delay is not guaranteed. Since all JavaScript in a browser executes on a single thread asynchronous events (such as mouse clicks and timers) are only run when there's been an opening in the execution.
Further read this: http://ejohn.org/blog/how-javascript-timers-work/
timeout = setTimeout('timeout_trigger()', 3000);
clearTimeout(timeout);
jQuery(document).ready(function () {
//hide a div after 3 seconds
setTimeout( "jQuery('#div').hide();",3000 );
});
refer link
function hover () {
$( ".sublist" ).parent().hover( function () {
$(this).toggleClass("li_hover",300); //use to change the background color
$(this).find(".sublist").toggle("slide", {}, 500); //sub list show / hide
});
}
setTimeout( hover,3000 );
....
You could use .setTimeout
$(".sublist").parent().hover(function() {
setTimeout(function() {
$(this).toggleClass("li_hover", 300); //use to change the background color
$(this).find(".sublist").toggle("slide", {}, 500); //sub list show / hide
}, 1000);
});
