Javascript button appear animation

I have the back to top button that appears when you reach a point on the page, which is working fine, however, when it appears the text is on two lines until the box has finished the animation to appear. So, is there anyway to prevent this? What I mean by the animation is: btt.show('slow');
Code:
$(document).ready(function () {
var btt = $('.back-to-top');
btt.on('click' , function(e) {
$('html, body').animate({
scrollTop: 0
}, 500);
btt.hide('slow');
e.preventDefault();
});
$(window).on('scroll', function () {
var self = $(this),
height = self.height(),
top = self.scrollTop();
if (top > 500) {
btt.show('slow');
} else {
btt.hide('slow');
}
});
});

The problem is caused by animating the width of a box, I think it might be better to animate the position of it instead, but - even better - lets use CSS animations!
$(window).on('scroll', function () {
if ($(window).scrollTop() >= 500) {
$(".button").addClass('show');
} else {
$(".button").removeClass('show');
}
});
#wrapper {
width: 100%;
height: 2000px;
}
.button {
position: fixed;
bottom: 50px;
right: -100px;
/* You might still need prefixes here. Use as preferred. */
transition: right 500ms;
}
.button.show {
right: 0;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.0/jquery.min.js"></script>
<div id="wrapper">
<div class="button">Here's my button!</div>
</div>
I've defined your button as hidden by default, by giving it a position of right: -100px. When we hit the correct scroll position, we add the class show and that triggers the animation performed by CSS and not javascript, as we have the transition property for the property right defined - that way the browser does the heavy lifting.

Toggling show/hide alters your elements width. You either have to put it in a container with display: inline
Or more ideally you might want to change show/hide to jQuery fadeIn() / fadeOut() which is more appropriate for "Back to Top" indicators.
Here is your codepen example modified with inline container:

override fadeout() display: none

Have a fiddle here:
http://jsfiddle.net/BP6rq/1514/
Fades my element out and puts it in a fixed position once it has reached the necessary point. I am using fadeOut() for the back-in effect. The problem is I do not want it to hide. I know about fadeTo, however I haven't been able to achieve that same effect. I've also tried overriding the display: none, but that eliminates the functionality of the fade effect. What can I do to maintain the fade effect, but not have fadeOut() disappear when scrolled back up and back to its original position?
Thoughts?

Use animate() together with css opacity instead of fadeIn fadeOut:
jsFiddle Demo
$(window).bind("scroll", function () {
$.fx.speeds.xslow = 250;
if ($(this).scrollTop() > 50) {
$('#bottomcta')
.animate({
'opacity': 1
},1000)
.addClass('fixed');
} else {
$('#bottomcta')
.animate({
'opacity': 0
},1000)
.removeClass('fixed');
}
});

Jquery, slideup() but do not remove element

I've got an app that looks like a Windows desktop. There are icons that open draggable windows (divs) which display the content.
When I close a window, this happens:
$('#element'+boxId).animate({height: 0, opacity: 0}, 'fast');
When I open a window, this happens
$('#element'+boxId).slideDown();
Problem is, once a window is closed, I cannot reopen it. If I want to see that window again I have to refresh the page and then open it.
Is there some way to do a cool fade out that does not completely remove the element?
I have also tried regular old slideUp() but that does the same thing.
This works fine, just not as cool looking.
document.getElementById('element'+boxId).style.display = "none";

The problem is that you are hiding it by affecting the height and opacity, and those aren't being reset by the slideDown. Here's one option:
http://jsfiddle.net/uggVb/
$('#hide').click(function (e) {
e.preventDefault();
var $div = $('#theDiv');
$div.data('originalHeight', $div.css('height'));
$('#theDiv').animate({
height: 0,
opacity: 0
}, 'fast');
//$('#theDiv').slideUp('fast');
});
$('#show').click(function (e) {
e.preventDefault();
$('#theDiv').animate({
height: $('#theDiv').data('originalHeight'),
opacity: 1
}, 'fast');
//$('#theDiv').slideDown('fast');
});
You could use the slide functions instead of the animate functions, either work.

How about only using jQuery to add and remove a hide class and use CSS transitions for the properties you want to animate?
jQuery:
$('#whatever').click(function(ev) {
var $el = $('#element' + boxId);
$el.toggleClass('hide');
});
CSS:
#element { /* or #element{{boxId}} or some class added to those elements */
opacity: 1;
overflow: hidden;
width: 100px; height: 100px;
transition: height 300ms, opacity 300ms;
}
#element.hide {
opacity: 0;
height: 0;
}
See demo

Not sure if it is what you want but you can look into jQuery hide/show functions
$('#element'+boxId).hide();
if you want slower/faster animation you can give hide parameter which represents animation speed(in miliseconds)
$('#element'+boxId).hide(1000);

jQuery rebind function

I want to have a div that animates the currently active image out of the view and instead animates in another image. There are several of these divs, and each one should have the same basic functionality but linked to different images. The problem I'm having is that you can click many of the divs before the animation is complete, which fires the other animations at the same time. My goal is to only be able to fire one animation at a time, and when the animation finishes you're able to fire the next animation. I've tried using unbind which works OK but then I'd have to rebind it later and I don't know how to do this. I'm really a jQuery noob so I would greatly apreciate an answer. Thanks!
My code:
$('.div1').click(function clickevent() {
$('.img2, .img3').animate({
opacity: 0.1,
left: 600
}, 1000, function() {
$('.img1').animate({
opacity: 1,
left: 0
}, 500, function() {
$('.div2, .div3').bind('click', clickevent); /* Here I want to rebind the function */
});
});
$(this).addClass("active");
$('.div2, div3').removeClass("active");
$('div2, .div3').unbind('click', clickevent);
});
I have two other codeblocks for .div2 and .div3 which look the same but with different classes in different places. Is there any way to make the images finish their animation before being able to animate again? Thanks.

Is this what you need:
var canAnimate = true;
$('.div1').click(function clickevent() {
// these 4 lines have to be in all code blocks (ie. for .div2 and .div3)
if (! canAnimate) {
return;
}
canAnimate = false;
$('.img2, .img3').animate({
opacity: 0.1,
left: 600
}, 1000, function() {
$('.img1').animate({
opacity: 1,
left: 0
}, 500, function() {
canAnimate = true; // this should also be included for .div2 and .div3 code blocks
});
});
$(this).addClass("active");
$('.div2, div3').removeClass("active");
});

I think queue() will append the animations but not stop them, so if you click 10 times on the images, the click handler will animate it 10 times but one after another. I guess you want only animate the images when no image is currenty animated so you can use:
$('.div1').click(function clickevent() {
// When no image is currently animated then perform the animation
if($j('.img1, .img2, .img3').is(':animated') == false)
{
$('.img2, .img3').animate({
opacity: 0.1,
left: 600
}, 1000, function() {
$('.img1').animate({
opacity: 1,
left: 0
}, 500);
});
$(this).addClass("active");
$('.div2, div3').removeClass("active");
} else {
// There is currently an animation runnig, do nothing
}
});

JQuery Fade On Hover Effect - help?

I'm trying to achieve a fade-on-hover effect with JQuery. Currently I have an element with a "hov" class attacked to it, without javascript the css will simply change it's color on :hover. With JQuery.
The idea is to clone the element as it's rolled over and place it directly infront, stripping it of the "hov" class so it's just static. Then I fade it out so it create the transition effect.
I'm having trouble though, after I strip the "hov" class from the clone, it KEEPS acting as though its still there. I can mouse over the clone even though it shouldn't be able to be targeted through hov. Any ideas / tips?
<a href="#" class="hov rounded-50 action-button">Fade Me Out< /a>
$(".hov").mouseover(function() {
// Clone the current element, remove the "hov" class so it won't trigger same behavior
// finally layer it infront of current element
var $overlay = $(this).clone(true).removeClass("hov").insertAfter($(this));
// Push it to the side just for testing purposes - fade it out
$overlay.css({left:'300px'}).fadeOut({duration:500, ease:'easeOutQuad'});
});

No need to clone the element, just fade the original element:
$('.hov').mouseenter(function() {
$(this).fadeOut();
});
// Optionally:
$('.hov').mouseleave(function() {
$(this).stop(true, true).show();
});
You can also use the hover function:
$('.hov').hover(function(){
$(this).fadeOut();
},
function(){
$(this).stop(true, true).show();
});
If you just want it to partially fade, you can animate the opacity property:
$('.hov').mouseenter(function() {
$(this).animate({'opacity': 0.5});
});
If you just want it to pulse, then return to normal opacity:
$('.hov').mouseenter(function() {
$this = $(this);
$this.animate({'opacity': 0.5}, {
'complete': function(){
$this.animate({'opacity': 1});
}
});
});
Finally, if your willing to forgo support of older browsers, you can do it all with css:
.hov {
-webkit-transition: opacity 0.3s ease-in;
-moz-transition: opacity 0.3s ease-in;
}
.hov:hover {
opacity: 0.5;
}
