How to Delay The First FadeIn Event On Slider

I am currently modifying this piece of code as apart of a project, it works fine for what I need it to do, however I want a relatively short transition period,but the initial div element only display for a brief moment and the fade process starts.
I was wondering if anyone could help me to correct this. Ideally I would like to set the initial slider timeframe or delay it from triggering the process,
var divs = $('.fade');
function fade() {
var current = $('.current');
var currentIndex = divs.index(current),
nextIndex = currentIndex + 1;
if (nextIndex >= divs.length) {
nextIndex = 0;
}
var next = divs.eq(nextIndex);
current.stop().fadeOut(500, function() {
$(this).removeClass('current');
setTimeout(fade, 5000);
});
next.stop().fadeIn(500, function() {
$(this).addClass('current');
});
}
fade();

To delay the function fade() from starting right away just do:
var divs = $('.fade');
function fade() {
....
}
setTimeout(fade, 5000); //here is the only change
At the end of your code fade() is executed right away. Just add a timeout to it. 5000 is in milliseconds, just switch that to the delay time you want.
Apart from your question, if you wanted to apply the fade function to objects only after you clicked them, you could do this.
$('.fade').on('click',function(){//instead of click you could use any event ex. mouseover
fade();//call fade function
});

Wow.js repeat animation every time you scroll up or down

I'm pretty new with Jquery. I would like that my animations with Wow.js could run more than once time. For instance: i scroll to the bottom of my page and see all the animations, and if i scroll back to the top i see again the animations like when you scroll down. I hope that I explained myself. I have already seen many websites that repeats the animations on theirs pages but unfortunately I don't remember them and I can't provide a link.
I have already tried this:
$(window).scroll(function(){
new WOW().init();
}
But it repeat the animations also if you scroll a little and it's pretty ugly to see. I try to explain me better: I have a with my animation and if it is focused the animation is triggered, then i scroll down to another div and the previous div is no more visible(not in the window viewport), then again i scroll back to my div with animation and the animation is triggered again.
I'm sorry for this messy question but I really don't know how to explain it.
Thanks in advance!

This example by Benoît Boucart shows how the animation can be "reset" when the user scrolls out of view and back in. The key here is the second function that removes the animation css class when the element scrolls out of view. I wish WOW.js would implement this, but they've indicated that they don't plan to.

Snippet:
// Showed...
$(".revealOnScroll:not(.animated)").each(function () {
var $this = $(this),
offsetTop = $this.offset().top;
if (scrolled + win_height_padded > offsetTop) {
if ($this.data('timeout')) {
window.setTimeout(function(){
$this.addClass('animated ' + $this.data('animation'));
}, parseInt($this.data('timeout'),10));
} else {
$this.addClass('animated ' + $this.data('animation'));
}
}
});
// Hidden...
$(".revealOnScroll.animated").each(function (index) {
var $this = $(this),
offsetTop = $this.offset().top;
if (scrolled + win_height_padded < offsetTop) {
$(this).removeClass('animated fadeInUp flipInX lightSpeedIn')
}
});

If a user wants to repeat the animation on both the events i.e.
onScrollUp
onScrollDown
then this will be a good solution for it:
First create an addBox function, it will help to push new elements into the WOW boxes array.
WOW.prototype.addBox = function(element){
this.boxes.push(element);
};
Then use jQuery and scrollspy plugin that helps to detect which element is out of the view and then push WOW as:
$('.wow').on('scrollSpy:exit',function(){
var element = $(this);
element.css({
'visibility' : 'hidden',
'animation-name' : 'none'
}).removeClass('animated');
wow.addBox(this);
});

Answer by #vivekk is correct I m just adding a working example so that people can easily get this
see the Demo fiddle
<script>
// Repeat demo content
var $body = $('body');
var $box = $('.box');
for (var i = 0; i < 20; i++) {
$box.clone().appendTo($body);
}
// Helper function for add element box list in WOW
WOW.prototype.addBox = function(element) {
this.boxes.push(element);
};
// Init WOW.js and get instance
var wow = new WOW();
wow.init();
// Attach scrollSpy to .wow elements for detect view exit events,
// then reset elements and add again for animation
$('.wow').on('scrollSpy:exit', function() {
$(this).css({
'visibility': 'hidden',
'animation-name': 'none'
}).removeClass('animated');
wow.addBox(this);
}).scrollSpy();
</script>

Using a jquery slider for text instead of images?

This may be a little too specific, but I have a jquery slider that I am using <p> classes instead of images to cycle through customer quotes. Basically the problem I am running into right now is when it is static and non moving (JS code is commeneted out) they are aligned how I want them to be. As soon as the JS is un commented, they stretch out of view and you just see a white box?
Any ideas?
How I want each panel to look like:
jsfiddle

So I sort of made this my Friday project. I've changed a whole lot of your code, and added a vertical-align to the quotes and authors.
Here's the fiddle http://jsfiddle.net/qLca2fz4/49/
I added a whole lot of variables to the top of the script so you could less typing throughout.
$(document).ready(function () {
//rotation speed and timer
var speed = 5000;
var run = setInterval(rotate, speed);
var slides = $('.slide');
var container = $('#slides ul');
var elm = container.find(':first-child').prop("tagName");
var item_width = container.width();
var previous = 'prev'; //id of previous button
var next = 'next'; //id of next button
Since you used a % based width I'm setting the pixel widths of the elements in case the screen is reszed
slides.width(item_width); //set the slides to the correct pixel width
container.parent().width(item_width);
container.width(slides.length * item_width); //set the slides container to the correct total width
As you had, I'm rearranging the slides in the event the back button is pressed
container.find(elm + ':first').before(container.find(elm + ':last'));
resetSlides();
I combined the prev and next click events into a single function. It checks for the ID of the element targeted in the click event, then runs the proper previous or next functions. If you reset the setInterval after the click event your browser has trouble stopping it on hover.
//if user clicked on prev button
$('#buttons a').click(function (e) {
//slide the item
if (container.is(':animated')) {
return false;
}
if (e.target.id == previous) {
container.stop().animate({
'left': 0
}, 1500, function () {
container.find(elm + ':first').before(container.find(elm + ':last'));
resetSlides();
});
}
if (e.target.id == next) {
container.stop().animate({
'left': item_width * -2
}, 1500, function () {
container.find(elm + ':last').after(container.find(elm + ':first'));
resetSlides();
});
}
//cancel the link behavior
return false;
});
I've found mouseenter and mouseleave to be a little more reliable than hover.
//if mouse hover, pause the auto rotation, otherwise rotate it
container.parent().mouseenter(function () {
clearInterval(run);
}).mouseleave(function () {
run = setInterval(rotate, speed);
});
I broke this in to its own function because it gets called in a number of different places.
function resetSlides() {
//and adjust the container so current is in the frame
container.css({
'left': -1 * item_width
});
}
});
//a simple function to click next link
//a timer will call this function, and the rotation will begin :)
And here's your rotation timer.
function rotate() {
$('#next').click();
}

It took me a little bit, but I think I figured out a few things.
http://jsfiddle.net/qLca2fz4/28/
First off, your console was throwing a few errors: first, that rotate wasn't defined and that an arrow gif didn't exist. Arrow gif was probably something you have stored locally, but I changed the 'rotate' error by changing the strings in the code here to your actual variables.
So, from:
run = setInterval('rotate()', speed);
We get:
run = setInterval(rotate, speed);
(No () based on the examples here: http://www.w3schools.com/jsref/met_win_setinterval.asp)
But I think a more important question is why your text wasn't showing up at all. It's because of the logic found here:
$('#slides ul').css({'left' : left_value});
You even say that this is setting the default placement for the code. But it isn't..."left_vaule" is the amount that you've calculated to push left during a slide. So if you inspect the element, you can see how the whole UL is basically shifted one slide's worth too far left, unable to be seen. So we get rid of 'left_value', and replace it with 0.
$('#slides ul').css({'left' : 0});
Now, there's nothing really handling how the pictures slide in, so that part's still rough, but this should be enough to start on.
Let me know if I misunderstood anything, or if you have any questions.

So, a few things:
1) I believe you are trying to get all of the lis to be side-by-side, not arranged up and down. There are a few ways to do this. I'd just make the ul have a width of 300%, and then make the lis each take up a third of that:
#slides ul {
....
width: 300%;
}
#slides li {
width: calc(100% / 3);
height:250px;
float:left;
}
2) You got this right, but JSFiddle automatically wraps all your JS inside a $(document).ready() handler, and your function, rotate needs to be outside, in the normal DOM. Just change that JSFiddle setting from 'onload' to 'no wrap - in head'
3) Grabbing the CSS value of an element doesn't always work, especially when you're dealing with animating elements. You already know the width of the li elements with your item_width variable. I'd just use that and change your code:
var left_indent = parseInt($('#slides ul').css('left')) - item_width;
$('#slides ul').animate({'left' : left_indent}, 1500, function () {
to:
$('#slides ul').stop().animate({'left' : -item_width * 2}, 1500, function () {
4) Throw in the .stop() as seen in the above line. This prevents your animations from overlapping. An alternative, and perhaps cleaner way to do this, would be to simply return false at the beginning of your 'next' and 'prev' functions if #slides ul is being animated, like so:
if ($('#slides ul').is(':animated')) return false;
And I think that's everything. Here's the JSFiddle. Cheers!
EDIT:
Oh, and you may also want to clearInterval at the beginning of the next and prev functions and then reset it in the animation callback functions:
$('#prev').click(function() {
if ($('#slides ul').is(':animated')) return false;
clearInterval(run);
$('#slides ul').stop().animate({'left' : 0}, 1500,function(){
....
run = setInterval('rotate()', speed);
});
});

Show / hide elements on mouse move

I'm building a site where I want the certain sections to be hidden until the mouse is moved. They then remain visible whilst the mouse is moving, however, if it remains still for a couple of seconds they hide again.
I'm using jQuery on the site, in my ready state I have:
var hide = setTimeout(function() {
hideNav();
}, 2000);
$('body').mousemove(function() {
clearTimeout(hide);
var hide = setTimeout(function() {
hideNav();
}, 2000);
showNav();
});
And the functions that show/hide content
function hideNav() {
$('#primary').fadeOut(1000);
var lightbox = $('#lightbox');
if (lightbox.length) {
lightbox.fadeOut(1000);
}
}
function showNav() {
$('#primary').fadeIn(1000);
var lightbox = $('#lightbox');
if (lightbox.length) {
lightbox.fadeIn(1000);
}
}
This sort of works, except the timeout for hiding the elements ends up fighting with the function to show it when the mouse moves resulting in a lot of flickering.
EDIT: The mouse movement needs to be for anywhere on the page, not just when hovering over the element that is to be shown/hidden.
Any help would be appreciated.
Thanks

Try using $.stop http://api.jquery.com/stop/
If its in the 1 second of fading out when you move your mouse, it should stop the animation of fading out and fade back in.
function hideNav() {
$('#primary').stop().fadeOut(1000);
var lightbox = $('#lightbox');
if (lightbox.length) {
lightbox.fadeOut(1000);
}
}
function showNav() {
$('#primary').stop().fadeIn(1000);
var lightbox = $('#lightbox');
if (lightbox.length) {
lightbox.fadeIn(1000);
}
}
Also, I would remove var from the var hide = ... in your mousemove function. If hide is a global variable, just reuse it inside mousemove (doesn't need to be redeclared).

Create Jquery Drop down using Divs and maintaing dual hover

What I'm trying to do is to fade in a div by rolling over a link. Once your mouse is over the link, you're able to mouse around the div that just faded in and you can click links inside the div.
Currently I have four links and each have a div with links and images in. On hover of the link the div fades in below the link then you can move your mouse over the div and use the images + links within. On roll out of the link or the div, it should fade out. Also, if you move your mouse to another main navigation link it should fade out the previous and fade in the new div.
The problem seems to be that the previous DIV will sometimes not fade out if you rapidly move to next link. I'm drawing a blank, any ideas?
Problem solved, answer is here: http://jsfiddle.net/UkneJ/3/
This is what I'm working with: http://jsfiddle.net/DemhU/17/
$('#div1, #div2, #div3, #div4').hide();
var is_over;
var hide_dropnav = function(a) {
setTimeout(function() {
if (is_over) {
return;
} else {
var a_name = $(a).attr('data-name');
$('#' + a_name).fadeTo(250, 0);
$('#nav li a').removeClass('active');
}
}, 10);
}
$('#nav li a').hover(function() {
var elem_name = $(this).attr('data-name');
$('#' + elem_name).stop(true,true).fadeTo(150, 1);
is_over = true;
$('#nav li a').removeClass('active');
$(this).addClass('active');
var that = this;
hide_dropnav(that);
}, function(){
is_over = false;
hide_dropnav(this);
});
$('#div1, #div2, #div3, #div4').hover(function() {
is_over = true;
}, function() {
is_over = false;
});

There are a lot of ways to do this, but I threw together a quick working example of the method I've used before:
http://jsfiddle.net/UkneJ/
In this example, I'm binding hover to both the A and the DIV, and using a slight delay to check is "is either element hovered?" state.
You can also just bind hover to the wrapping LI, which makes things much simple. This only works if both your link and your div are contained in each LI, though:
