how to attach scroll event to window after scroll animation

I'm trying to display a div after scroll animation has finished and hide it when I scroll up/down the page. This is my attempt:
$('#cta').on('click', function(e) {
e.preventDefault();
$('#layer, #servicesContent').addClass('active');
var position = parseInt($('#services').offset().top);
$('html, body').animate({
scrollTop: position - 100
}, 'slow', function() {
$(window).bind('scroll', function() {
$('#layer, #servicesContent').removeClass('active');
});
});
});
it doesn't work. the active class is removed after animation has finished and not with scroll movement.
Any idea?
Thanks in advance

Not exactly sure why, but apparently it takes the window somewhere around 20 milliseconds to exit the scroll state, at least on Chrome, on Windows. Or it might be a jQuery trick to fire the animation function 20ms sooner, so it feels more natural. (Human eye and mind make connections that take tiny amounts of time and maybe they took it into account).
Anyway, in order to make sure you bind after the scroll has ended, give it a full 100ms to finish and bind afterwards:
$('#cta').on('click', function(e) {
e.preventDefault();
$('#layer, #servicesContent').addClass('active');
var position = 120;
$('html, body').animate({
scrollTop: position - 100
}, 'slow', function() {
setTimeout(function(){
$(window).bind('scroll', function() {
$('#layer, #servicesContent').removeClass('active');
});
},100)
});
});
working fiddle.
Please note I had hard-coded a value to position, as #services is not defined in my example.
Also please note that hiding events on scroll is a really bad idea in terms of usability. Users might want to scroll so they view the div better or read it in full, but they will end up hiding it, which would be annoying. I would at least check the scroll event for a minimum velocity or distance in order to hide an element from the screen.

Javascript/jQuery - trigger action only when mouse moves

I need to trigger an action only once when user moves the mouse slightly and it doesn't matter on what part of the page. If the mouse doesn't move, action shouldn't be triggered. When mouse moves (could be 3 minutes after the page is completely loaded), then the action should take place only once.
This is what I have right now:
$(document).one('mousemove', function() {
$('.front #main .block-content').animate({opacity : 0.3}, 200);
});
The problem is immediately after the page is completely loaded, the animation will be triggered, no matter what I do with the mouse (stopped or moving).
I hope I was clear enough, but I can try to clarify further if this isn't enough. Is there a solution for this I am trying to achieve?
Thank you.

use
$(document).mousemove(function(){
$('.front #main .block-content').animate({opacity : 0.3}, 200);
})
instead

jQuery SlideDown() is not waiting for delay on animation

I use jQuery function that should animate divs (Slide down and up) like a dynamic menu or something.
The problem is even I set up delay() - when mouse goes over it, no matter how long the cursor stays over one div it will slidewon and up.
To clarify. If I put a mouse over the certain div, it works well, it waits the delay and then slide. But if I fast goes over all divs in the example it will make a weird reaction, like the divs start to slide down but then suddenly stops and go up. Try my fiddle and you'll see.
This is the FIDDLE
jQuery(".subdiv").hide();
jQuery(".mydiv").hover(function(){
jQuery(this).find(".subdiv").stop().delay(800).slideDown("slow");
}, function(){
jQuery(this).find(".subdiv").stop().delay(200).slideUp("slow");
});

So something like this:
http://jsfiddle.net/GzxJf/12/
jQuery(".subdiv").hide();
jQuery(".mydiv").hover(function(){
jQuery(".subdiv").each(function() {
if(jQuery(this).attr('display') !== "none") {
jQuery(this).stop(true).slideUp("slow");
}
});
jQuery(this).find(".subdiv").slideDown("slow");
}, function(){
jQuery(this).find(".subdiv").slideUp("slow");
});

Content Fade In over background

I'm working on this site: http://mccraymusic.com/newsite/ and I am having trouble figuring how to fade in the navigation bar correctly over the background AFTER the background has faded when clicking "enter site." I know the navigation bar isn't styled yet. I'm pretty sure I have the right code for the navigation to fade in. Just not sure how to make it work so it fades in when I want it.
Thanks

I suspect you need to use a callback in jQuery. Basically, the second function runs AFTER the first has completed.
http://www.w3schools.com/jquery/jquery_callback.asp

Here is a fiddle of it http://jsfiddle.net/YL4p7/
Fadein has a builtin callback, just add you animation into that callback and it will execute after the background has faded in.
also add relative position to #container so that it can be seen over the bg image.
$(function() {
var images = ["black.jpg","bg.jpg"];
$('<img>').attr({'src':'http://mccraymusic.com/newsite/assets/images/'+images[0],'id':'bg','alt':''}).appendTo('#bg-wrapper').parent().fadeIn(0);
$('.move').animate({
top:200,
left:250,
});
$('.entersite').click(function(e) {
e.preventDefault();
var image = images[1];
$('#bg').parent().fadeOut(200, function() {
$('#bg').attr('src', 'http://mccraymusic.com/newsite/assets/images/'+image);
$(this).fadeIn(1000, function() {
$('.navbar').fadeIn(1000);
});
});
$('.move').animate({"left": "-=50px", "top": "-=200px"});
});
});​

jquery .animate() - this code sort of does what i want

I am trying to make a div slide down when the mouse moves over another div just above it. Basically the div above it is just the trigger that makes the div slide down. Mouseover of .trigger makes .slidedown expand, and mouseout of .slidedown makes itself slide back up. Here's the code i have so far:
$(document).ready(function() {
$('.slidedown').hide();
//When mouse rolls over
$('.trigger').mouseover(function(){
$('.slidedown').stop().animate({
height: ['toggle', 'swing'],
}, 600, function() {
// Animation complete.
});
});
//When mouse is removed
$('.slidedown').mouseout(function(){
$('.slidedown').stop().animate({
height:'0px'
}, 600, function() {
// Animation complete.
});
});
});
This works, but there are just two teaks i need help with. Firstly, after mouseout and the .slidedown div slides up and disappears, if i then mouse over the .trigger div again, nothing happens. It should make the .slidedown move down again. I need it to every time keep working. I tried removing the .stop() but it still doesn't work.
Also can i make it also slide back up if the mouse moves out of .trigger but only if it isn't moving out of .trigger into .slidedown? This is so incase the user doesn't move the mouse into .slidedown, it would remain forever which isn't good. Or just have a time limit that it can remain expanded if the mouse doesn't move over .slidedown.
Second, is there a way to make a delay of around 1 second between mouseout and the div sliding back up? Thanks for your help!

You might try using the jQuery hover event. For the delay, you can put the closing animation in setTimeout:
$(document).ready( function(){
$('.trigger').hover( function(){ // enter animation
$('.slidedown').stop(true,true).animate({
height: ['toggle', 'swing'],
}, 600, function() { /* animation done */ });
}, function(){ // leave animation
setTimeout( function(){
$('.slidedown').stop(true,true).animate({
height: '0px',
}, 600, function() { /* animation done */ });
}, 1000 );
});
});
You might also look into the hoverIntent plug-in for more nuanced control over the mouseenter/mouseleave behavior, including timing.

I think you'll find that setting a numerical height in $('.trigger').mouseover() may help the animation be repeatable. FYI, you can set an integer number for something like height or width in jQuery and it will automatically set the unit to px for you.
As Ken pointed out, setTimeout is useful for a delay in code, but keep it in your $('.slidedown').mouseout() event or the slideown div will hide after you mouseout of the trigger div instead of when you leave the slidedown div as you specified.
