I have a list of DIVs, and I want every X second using setTimeout to take the next div and set the display to block, and for the other ones to none, how can I do that? Can someone please give me an example?
How can I make it to be infinite, when reaches the last one to start from the first one again.
I know this is a kind of carousel, but I want too see how it's done.
There are many ways to do this, but here's one way: http://jsfiddle.net/jfriend00/Yr3NV/
HTML:
<div id="container">
<div class="item active">1111</div>
<div class="item">2222</div>
<div class="item">3333</div>
<div class="item">4444</div>
<div class="item">5555</div>
<div class="item">6666</div>
<div class="item">7777</div>
</div>
Code:
setInterval(function() {
var next = $("#container .active").removeClass("active").next();
if (next.length == 0) {
next = $("#container .item:first");
}
next.addClass("active");
}, 1000);
CSS:
.item {display: none;}
.item.active {display: block;}
Using the method of adding/removing a class gives you a little more style control via CSS rather than coding the style into your javascript and avoids the use of any global or closure variables to keep the state.
var divs = $('#container').find('div'),
index = 0;
setInterval(function() {
if (!divs[index]) index = 0;
divs.hide();
divs[index++].style.display = 'block';
}, 1000); // fires every 1 second
All the usual disclaimers about global scope being a bad idea, but this should give you what you want.
$("#list div").hide();
var current = $("#list div").first().show();
setInterval(function() {
current.hide();
current = current.next().length > 0 ? current.next() : $("#list div").first();
current.show();
},2000);
<div id="list">
<div>1</div>
<div>22</div>
<div>333</div>
<div>4444</div>
</div>
Can be seen working here:
http://jsfiddle.net/KenwV/
Here's an implementation with setTimeout: http://jsfiddle.net/imsky/EBpTw/
Given a UL with id of "list" and LIs inside:
$(function() {
$("#list li:gt(0)").hide();
function showNextBlock() {
var currentBlock = $("#list li:visible");
if (currentBlock.index() == $("#list li").length - 1) {
currentBlock.hide().parent().find("li:first").show()
}
else {
currentBlock.hide().next("li").show();
}
setTimeout(showNextBlock,1000);
}
setTimeout(showNextBlock,1000);
});
DIV LOOP DEMO
var i=0, len=$('#parent div').length;
(function loop(){
$('#parent div').eq(i++%len).fadeTo(700,1).siblings().fadeTo(700,0,loop);
})();
HTML example:
<div id="parent">
<div class="children ch1">I'm DIV 1</div>
<div class="children ch2">I'm DIV 2</div>
<div class="children ch3">I'm DIV 3</div>
<div class="children ch4">I'm DIV 4</div>
</div>
CSS basic setup:
.children{
position:absolute;
}
And here is one with a mouseover pause :
DEMO with mouseover pause
function cycleDivs(base)
{
var next = ($(base).next('div').css('display') == 'none')? $(base).next('div') : $('div:first');
$(base).hide();
$(next).show();
window.setTimeout(function(){cycleDivs(next);}, 1000)
}
window.setTimeout(function(){cycleDivs($('div:first'));}, 1000);
Here's a working example: http://jsfiddle.net/8hfBd/

I can't make my jQuery function work on individual elements. My function is a slider. When I put one slider to my html, it works fine, without problems. But whenever I try to put a second slider, it doesn't work properly. The first slider controls both of them, then the second slider takes the charge if I click right arrow too much etc.
Here is my jQuery code:
$('.right-arrow').click(function () {
var currentSlide = $('.slide.active');
var nextSlide = currentSlide.next();
currentSlide.fadeOut(300).removeClass('active');
nextSlide.fadeIn(300).addClass('active');
if (nextSlide.length == 0) {
$('.slide').first().fadeIn(300).addClass('active');
}
});
$('.left-arrow').click(function() {
var currentSlide = $('.slide.active');
var prevSlide = currentSlide.prev();
currentSlide.fadeOut(300).removeClass('active');
prevSlide.fadeIn(300).addClass('active');
if (prevSlide.length == 0) {
$('.slide').last().fadeIn(300).addClass('active');
}
});
And this is where I use it:
<style>
.slide {
display:none;
}
.slide.active {
display:block;
}
</style>
<div class="slider-container">
<div id="slider1">
<div class="slide active">#1</div>
<div class="slide">#2</div>
<div class="slide">#3</div>
</div>
<p class="left-arrow"><</p>
<p class="right-arrow">></p>
</div>
<div class="slider-container">
<div id="slider2">
<div class="slide active">#a</div>
<div class="slide">#b</div>
<div class="slide">#c</div>
</div>
<p class="left-arrow"><</p>
<p class="right-arrow">></p>
</div>
Like I said previously, when I click the first slider's right arrow, first slider's #2 and second slider's #b shows up.
You are getting this behavior because of the line
var currentSlide = $('.slide.active');
which selects all elements with the classes slide and active. try replacing that line with something like this:
var currentSlide = $(this).parent().find('.slide.active');
What this is doing is selecting the element the event was fired on $(this). Then getting the parent of that element, then finding the active slide within that element.
EDIT
Here is an example of your first if statement. Once again, you are getting the parent of the element that caused the event, then searching inside that dom element for all of the elements with a class of 'slide'.
As a side note you might want to make $(this) a variable something like var $this = $(this). Then use $this instead of $(this). It's a performance issue that you may or may not be concerned with.
if (nextSlide.length == 0) {
$(this).parent().find('.slide').first().fadeIn(300).addClass('active');
}
As other answers and comments mentioned, you are searching the .slide elements on the whole document. Instead you need to limit the search inside the related .slider-container element. For this purpose, you can use JQuery.closest(). Also, it will be nice to wait the fadeOut animation to finish using the complete callback function before showing the new .slide element. You can take next example as reference of implementation:
$('.right-arrow').click(function()
{
var container = $(this).closest(".slider-container");
var currSlide = container.find('.slide.active');
var nextSlide = currSlide.next(".slide");
if (nextSlide.length === 0)
nextSlide = container.find('.slide:first-child');
currSlide.fadeOut(300, function()
{
$(this).removeClass('active');
nextSlide.fadeIn(300).addClass('active');
});
});
$('.left-arrow').click(function()
{
var container = $(this).closest(".slider-container");
var currSlide = container.find('.slide.active');
var prevSlide = currSlide.prev(".slide");
if (prevSlide.length === 0)
prevSlide = container.find('.slide:last-child');
currSlide.fadeOut(300, function()
{
$(this).removeClass('active');
prevSlide.fadeIn(300).addClass('active');
});
});
.slide {
display:none;
}
.slide.active {
display:block;
}

I have inside 3 divs inside one one aside another and every of those 3 divs shows one image.
How to make that at the time only one is visible and after 5 seconds visible fade out and next fade in and same in round indefinite time.
<div id="container">
<div id="one"></div>
<div id="two"></div>
<div id="three"></div>
</div>
You can Do Some thing like This
var i = 0;
window.setInterval(function() {
$("#container").find("div").each(function() {
$(this).hide();
});
$("#container").find("div:eq(" + i + ")").slideDown(500);
i++;
if (i==2) {
i = 0;
}
}, 5000);
I have this div scrolling script:
$(document).ready(function () {
$('.tab-box').each(function () {
var top = 0;
var $tabbox = $(this);
var height = $tabbox.height();
$(this).find('.tab').each(function () {
var shift = top;
$(this).click(function () {
$tabbox.find('.items').animate({
marginTop: shift + 'px'
});
$tabbox.find('.tab').removeClass('active');
$(this).addClass('active');
});
top -= height;
});
$(this).find('.tab:eq(0)').addClass('active');
});
});
If I understand it correctly it gets every divs working only within the div "tab-box".
http://jsfiddle.net/9SfEH/5/
What I want to change is that I separate the "tabs" from the main tab-box div, but make them still controll the "items".
http://jsfiddle.net/w65Dn/1/
I was trying for a simple solution buuut couldn't come up with one by myself.
Thanks everyone in advance :)
The problem was that in the original code, it was looking for the tab clickables using $(this).find(".tab"), but the .tabs were no longer inside of the .tab-box. So, if you just search globally, with $(".tab"), it works.
Note that you can no longer have more than one tab box, because it is searching globally for the .tabs. You could use something like javaCity's solution (i.e. wrapping everything in another div) to fix this.
You were looking for .tabs inside the tab-box which does not exist. So how about creating a div outside of .tabs which also encloses tab-box?
http://jsfiddle.net/3D8we/
HTML:
<div class="enclosingDiv">
<div class="tabs">
<div class="tab">1</div>
<div class="tab">2</div>
<div class="tab">3</div>
</div>
<div class="tab-box">
<div class="items">
<div class="item" style="background: #cbe86b;"></div>
<div class="item" style="background: #f2e9e1;"></div>
<div class="item" style="background: #1c140d;"> </div>
</div>
</div>
</div>
JS:
$(document).ready(function () {
$('.tab-box').each(function () {
var top = 0;
var $tabbox = $(this);
var height = $tabbox.height();
$('.enclosingDiv').find('.tab').each(function () {
var shift = top;
$(this).click(function () {
$tabbox.find('.items').animate({
marginTop: shift + 'px'
});
$tabbox.find('.tab').removeClass('active');
$(this).addClass('active');
});
top -= height;
});
$(this).find('.tab:eq(0)').addClass('active');
});
});
On line 7, change the selector from this to .tabs
$(this).find('.tab') becomes $(.tabs).find('.tab')

i have these two divs and would like to know how can i display the second (box2) div every 3 seconds.
<div id="box1" style="background-color:#0000FF">
<h3>This is a heading in a div element</h3>
<p>This is some text in a div element.</p>
</div>
<div id="box2" style="background-color:red">
<h3>This is a heading in a div element</h3>
how can i do this with jquery ?
i created a fiddle here. http://jsfiddle.net/jRmrp/5/
Update 1
The answer given by Khanh TO works but i am wondering what to do when div count is more than 2. it only allows for two.
You need this?
setInterval(function(){
$("#box2").toggle();
$("#box1").toggle();
},3000);
DEMO
Updated with new requirement:
var currentIndex = 0;
$(".box:not(:eq("+ currentIndex +"))").hide();
var totalDiv = $(".box").length;
setInterval(function(){
currentIndex = (currentIndex + 1) % totalDiv;
$(".box").hide();
$(".box").eq(currentIndex).show();
},3000);
DEMO
jsFiddle demo
doBoxBlink = setInterval(blink, 1500);
function blink() {
$('#box2').toggle();
}
I have a div with several images. I need to only display 6 at a time. I then need to fade out current six and fade in next 6 in the list.
I have this wrapped in a setInterval function. Is this possible?
So far, I’ve got:
var hiddenElements = $('.logos div.logo:gt(5)');
hiddenElements.hide();
setInterval(function() {
// …
}, 2000);
"logo" is the class of the divs that need to fade. They all have CSS background images (hence no img tags).
This is very straight approach. Just for fun. But you should optimize your html. Wrap every 6 images in one container and then toggle them - it will more clean and nature solution.

<div class='hidden'>1</div>
<div class='hidden'>2</div>
<div class='hidden'>3</div>
<div class='hidden'>4</div>
<div class='hidden'>5</div>
<div class='hidden'>6</div>
<div class='hidden'>7</div>

<div class='hidden'>15</div>
<div class='hidden'>16</div>
<script>
$(function(){
fadeByEachSlice(".hidden",6)
})
function fadeByEachSlice(object, step){
var i = 0;
objects = $(object)
function nextSlice(){
if(i%step == 0){
if( i <= objects.length ){
slice = objects.slice(i, step+i);
fadeSlice(slice)
}
}
}
function fadeSlice(slice){
$(slice).fadeIn().delay(1000).fadeOut("fast", function(){
i+=1; nextSlice();
})
}
nextSlice()
}
</script>
you can use jQuery delay function to show 6 images for a while and then fadeout them and fadein next six.
