Sequential order of Javascript functions

I'm having a bit of a problem with Javascript. I have a list of article titles which, when you click a title, the corresponding article appears on the right hand side (fixed at the top of the page). I have got these articles to fade in/out using Javascript. I also have a function which, when you are scrolled down and click on an article title, scrolls the page slowly back up to the top.
The problem I have is that when the page scrolls up and the article changes at the same time, the animations on both become quite choppy, especially in Safari. Is there any way to make the page scroll to the top first, then make the article change?
I'm basically asking if there is away to make my Javascript functions happen one after the other, rather than at the same time?
Heres my Javascript:
$(document).ready(function () {
$('.scrollup').click(function () {
$("body").animate({
scrollTop: 0
}, 'slow');
return false;
});
$('.articlelist ul li').click(function() {
var i = $(this).index();
$('.fullarticle').fadeTo(500,0);
$('#article' + (i+1)).fadeTo(500,1);
});
});
Any help would be hugely appreciated!
Thank you

I'm guessing you want to keep the click functionality on your article list and only the elements with class scrollup have 2 animations.
$(document).ready(function () {
$('.articlelist ul li').click(function () {
var i = $(this).index();
if ($(this).is(".scrollup")) {
$("body").animate({
scrollTop: 0
}, 'slow', function () {//when animation completes
fadeArticle(i);
});
} else {
fadeArticle(i);
}
});
function fadeArticle(i) {
$('.fullarticle').fadeTo(500, 0);
$('#article' + (i + 1)).fadeTo(500, 1);
}
});

In your call to animate() you'd want to add a function to be called upon completion. The animate function provided by JQuery takes a function as an optional parameter. When the animation completes that function is called.
You could use something like this:
$('.scrollup').click(function () {
$("body").animate({
scrollTop: 0
}, 'slow', showArticle);
return false;
});
showArticle would be a call to a function that fades the article in like the anonymous one in your click listener. You would probably need some way to pass an argument about which article should be shown.

I'm relatively new to this, but I think this may work. What I'm trying to do is enclose each of these as a callable function and then pass one function as the callback to the other.
$(document).ready(function () {
scrollTop(showArticle());
});
function scrollTop(callback) {
$('.scrollup').click(function () {
$("body").animate({
scrollTop: 0
}, 'slow');
callback;
});
}
function showArticle() {
$('.articlelist ul li').click(function () {
var i = $(this).index();
$('.fullarticle').fadeTo(500, 0);
$('#article' + (i + 1)).fadeTo(500, 1);
});
}

jQuery Animations Control Sequence

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();
});

Delay in show after 2 second by jquery

I want if user moved the mouse for two seconds (Keep the mouse button for two seconds) on a class, show to he hide class. how is it? ()
If you move the mouse tandem (several times) on class, You will see slideToggle done as automated, I do not want this. How can fix it?
DEMO: http://jsfiddle.net/tD8hc/
My tried:
$('.clientele-logoindex').live('mouseenter', function() {
setTimeout(function(){
$('.clientele_mess').slideToggle("slow");
}, 2000 );
}).live('mouseleave', function() {
$('.clientele_mess').slideUp("slow");
})​

Please try this below link Your Problem will solve
http://jsfiddle.net/G3dk3/1/
var s;
$('.clientele-logoindex').live('mouseenter', function() {
s = setTimeout(function(){
$('.clientele_mess').slideDown();
}, 2000 );
}).live('mouseleave', function() {
$('.clientele_mess').slideUp("slow");
clearTimeout(s)
})

Write your html like this
<div class="clientele-logoindex">Keep the mouse here
<div class="clientele_mess" style="display: none;">okkkkkkko</div></div>

Record when a timer is started and check if one exists before starting a new one:
window.timer = null;
$('.clientele-logoindex').live('mouseenter', function() {
if(!window.timer) {
window.timer = setTimeout(function(){
$('.clientele_mess').slideToggle("slow");
window.timer = null;
}, 2000 );
}
}).live('mouseleave', function() {
$('.clientele_mess').slideUp("slow");
})​

Take a look at hoverIntent is a jquery plugin to ensure hover on elements.

Issues with clearTimeout

I am trying to build a simple navigation with sub-navigation drop-downs. The desired functionality is for the drop-down to hide itself after a certain amount of seconds if it has not been entered by the mouse. Though if it is currently hovered, I would like to clearTimeout so that it does not hide while the mouse is inside of it.
function hideNav() {
$('.subnav').hover(function(){
clearTimeout(t);
}, function() {
$(this).hide();
});
}
$('#nav li').mouseover(function() {
t = setTimeout(function() { $('.active').hide()}, 4000);
//var liTarget = $(this).attr('id');
$('.active').hide();
$('.subnav', this).show().addClass('active');
navTimer;
hideNav();
});
What am I missing? Am I passing the handle wrong?

You should also clear the timeout in mouseover, before setting the new timeout.
Otherwise a timeout started before will still be active, but no longer accessible via the t-variable.

you can make the timer variable global.
function hideNav() {
$('.subnav').hover(function(){
clearTimeout(window.t);
}
}
$('#nav li').mouseover(function() {
window.t = setTimeout(function() { $('.active').hide()}, 4000);
});

Try doing it the recommended way (JS statement as a string):
t = setTimeout("$('.active').hide()", 4000);

Help needed Pausing/Resuming FadeIn and FadeOut

Hopefully this is a simple request. I found this code that will work perfectly for what I want to do (Rotate through list items while fading in and out) http://jsfiddle.net/gaby/S5Cjm/1/ . However, I am looking to have the animation pause on mouse over and resume on mouse out. I am a novice at the moment with Javascript and JQuery, so any help would be appreciated.
Thanks.
EDIT: Side questions: Is there a benefit to using JQuery to do this? Would a stand alone script be more appropriate?

I attached the hover event to your list items. The over function stops the animation and all following animations using jQuery.stop(true). The out function resumes the animation:
http://jsfiddle.net/US4Fc/1/
var duration = 1000
function InOut(elem) {
elem.delay(duration).fadeIn(duration).delay(duration).fadeOut(
function() {
if (elem.next().length > 0) {
InOut(elem.next());
}
else {
InOut(elem.siblings(':first'));
}
});
}
$(function() {
$('#content li').hide().hover(
function() {
$(this).stop(true)
},
function() {
var curOp = Number($(this).css("opacity"));
$(this).fadeTo(duration*(1-curOp), 1, function() {
InOut($(this))
});
}
);
InOut($('#content li:first'));
});

Will this work for you?
$(function(){
var active;
$('#content li').hide().hover(
function(){
active = $(this).stop();
},
function(){
active && InOut(active);
}
);
InOut( $('#content li:first') );
});
