I'm having an unexpected effect and some other bugs when trying to use show/hide with mouseover and mouseout.
What I was trying to do is have a box (div) and when you would mouse over it, another box would appear and slide to the right.
Here's the fiddle for it
http://jsfiddle.net/XtXGR/
Now there's two problems with it. One is the flickering and the other is that it appears by growing from the top-left corner and what I want it to do is appear from the left.
Any help would be greatly be appreciated. Thanks
I think I know what causes the flickering from the similar questions but I still need help with the other issue. Thanks!
Oh also just so you know the context in which this will be used is on a page with a table of items and each item would be the object in the fiddle link I posted above.
The main issue is that moving over a different child element of the container will trigger a mouseout and mouseover combination, which is why you see the element expanding and collapsing. IE circumvented this with the mouseenter and mouseleave events, which act exactly like the CSS :hover.
Speaking of which, the jQuery hover function has this feature too. You should use that instead of mouseover and mouseout.
According to the show API, you should use the slide effect to get what you want.
Your final code should look like this: http://jsfiddle.net/XtXGR/28/
A couple things:
If you want to do a fadein/out this would be better:
$(document).ready(function(){
$("div.item_container").hover(function() {
$("div.item_body").fadeIn(500);
}, function() {
$("div.item_body").fadeOut(500);
});
});
Also, you should probably float the div .item_body to the left..

How about using CSS3 transitions instead?
See this: http://jsfiddle.net/EVDj6/2/
Something like this? Using slide will give you the slide from default left effect.
$(document).ready(function(){
$("div.item_container").on('hover',function(){
$("div.item_body").toggle('slide',500);
});
});

There were many issues in your code. The href's were invalid and the floating of the elements was not 100% correct. One of the main issues was that you had display:none in your CSS. Bring that dispay:none out and of the CSS and put it inline on the item you want to show/hide. When its default state is "hide" then you need to bring the display:none inline.
Look at this fiddle to get a better idea of how to go about this with a bit more valid syntax:

I made something fast, you can go crazy with it :) The animation is pretty smooth, I hope it's useful for you.

I'm using a drop-down-menu which I modified to use animations such as SlideOut and FadeIn using onmouseover and onmouseout.
The problem comes after hovering through all of the nested lists a few times, which results in the second nested list becoming cut off.
You can replicate the bug by moving from "nav 1" to "nav 2" and back again rapidly.

Please and thank you for any advice / criticism.
Please see this fiddle: http://jsfiddle.net/SuRJ9/
The code I've changed:
function slideDown(toSlide) {
currentHover(toSlide);
$($(toSlide).children('ul')[0]).slideDown('medium',
function(){ $(this).css('overflow','visible') });
}
I've added resetting overflow to visible after finishing animation. overflow is set to hidden by jQuery in order to make sliding animation.
Also, please don't use onmouseout="slideUp(this)" and onmouseover="slideDown(this)", this is obtrusive JavaScript and is a bad technique. You should assign these events using jQuery.
$.fadeOut/In() apply certain styles before running the animation. These are remove when the animation completes.
Your fadeOutNav() is calling stop(true) , which if done while fadeOut() or fadeIn() are working, will leave the style's they have applied to the element. In this case overflow:hidden on the parent ul. You can remove the stop and let the effects bubble up, or insert a .css('overflow','') to your chain.
I have a button that, when hovered over, shows a <span> that is otherwise hidden. What I'm trying to figure out is how to transition the button's expansion on :hover so it's more smooth. I tried using CSS3 transitions but couldn't quite get it down. Plus I don't know if that's the best solution anyway.
EDIT: I added some jQuery but must have something wrong. Here's the script I used, after reading a previous answer here (which I'll reference if I can find it again):
$('a:has(span)').hover(
function() { $('span', this).fadeIn(); },
function() { $('span', this).fadeOut(); },
);
I've created a Fiddle: http://jsfiddle.net/UYexr/. Can anyone help me out?
If I were you I would avoid using CSS3 simply because of its lack of support; given that I would probably stick to JS animation.
The best way I would see to do this is to make the span have display:inline-block; with a defined width. Then you can use a javascript animation library to animate the span's display.
Personally, I would go about using jQuery's animate method. Although there are plenty of js animation libraries...
My slideToggle is a little jumpy at the bottom of the slide transition. Could that be because there is a button there or something. Any way to make it smoother. Tried using easing but not very successful. Any suggestions

The site
$(document).ready(function() {
$('.drop').click(function() {
$(this).parent().next('li.drop_down').slideToggle();
return false;
});
});
Give your li.drop_down a fixed width. This should clear it up. I don't remember the exact reason for this, but I just tested it on your site, and it works.
Right now the computed width is 217px so try that.
.drop_down {
width: 217px;
}
EDIT: Looks like you have a .drop_down2 and a .drop_down3 as well (maybe more). You would need to do the same for those. I'd suggest assigning a common class for each.
Try storing the height of each item before animating it, and then re-apply that height to the element just before starting the hiding animation.
Here's an article I wrote how with an example of doing this:
http://www.pewpewlaser.com/articles/jquery-smooth-animation
Fixed width didn't work for me, but what did was adding a clearfix class to the animated element, since I had some floated elements inside.
By default if you specify a speed jquery adds a weird looking animation where it expands from the left end corner. I want it to just slide down. Is there a way to do that without importing something else like jquery UI ?
I'm looking something in the lines of :
$("test").show('slow', {animation:'slide'})
If there's no way, then what would be the lightest solution to do this?
Thanks
There are the slideDown, slideUp, and slideToggle functions native to jquery 1.3+, and they work quite nicely...
https://api.jquery.com/category/effects/
You can use slideDown just like this:
$("test").slideDown("slow");
And if you want to combine effects and really go nuts I'd take a look at the animate function which allows you to specify a number of CSS properties to shape tween or morph into. Pretty fancy stuff, that.
Use slidedown():
$("test").slideDown("slow");
You can also use a fadeIn/FadeOut Combo, too....
$('.test').bind('click', function(){
$('.div1').fadeIn(500);
$('.div2').fadeOut(500);
$('.div3').fadeOut(500);
return false;
});

As you can see when you mouse over the images the div slides up and down to show more information. Unfortunately I have 2 problems that i can't figure out and I've searched but haven't found quite the right answer through google and was hoping someone could point me in the direction of a tutorial.
The first problem is that when you mouse over an image it changes to color (loads a new image), but there's a short delay when the image is loading for the first time so the user sees white. Do I have to preload the images or something in order to fix that?
My second problem is that when you move your mouse over the 'additional content area' it goes crazy and starts going up and down a bunch of times. I just don't have any idea what would cause this but i hope one of you will!
All my code is directly in the source of that page if you would like to view the source.
Thanks in advance for your help!
Yes, you have to preload the images. Thankfully, this is simple:
var images_to_preload = ['myimage.jpg', 'myimage2.jpg', ...];
$.each(images_to_preload, function(i) {
$('<img/>').attr({src: images_to_preload[i]});
});
The other thing you have to understand is that when you use jQuery you have to truly embrace it or you will end up doing things the wrong way. For example, as soon as you find yourself repeating the same piece of code in different places, you are probably doing something wrong. Right now you have this all over the place:
<div id="service" onmouseover="javascript:mouseEnter(this.id);" onmouseout="javascript:mouseLeave(this.id);">
Get that out of your head. Now. Forever. Always. Inline javascript events are not proper, especially when you have a library like jQuery at your disposal. The proper way to do what you want is this:
$(function() {
$('div.box').hover(function() {
$(this).addClass('active');
$(this).find('div.slideup').slideDown('slow');
}, function() {
$(this).removeClass('active');
$(this).find('div.slideup').slideUp('slow');
});
});
(You have to give all the #industrial, #sustainable, etc elements a class of 'box' for the above to work)
These changes will also fix your sliding problem.
I can see your images (the ones that are changing) are set in the background of a div. Here is a jquery script that preloads every image found in a css file. I have had the same problem in the past and this script solves it. It is also very easy to use:
http://www.filamentgroup.com/lab/update_automatically_preload_images_from_css_with_jquery/
I will take a look at your other problem...
1) You should be using the jquery events to drive your mouseovers. Give each div a class to indicate that its a category container and use the hover function to produce the mouseover/mouseout action you're after.
html
<div id="industrial" class="category"></div>
Javascript
$(".category").hover(
function () {
$(this).find('.container').show();
},
function () {
$(this).find('.container').hide();
}
);
I simplified the code to just do show and hide, you'll need to use your additional code to slide up and slide down.
2) Yes, you need to preload your images. Another option would be "sprite" the images. This would involve combining both the black and white and colour versions of each image into a single image. You then set it as the div's background image and simply use CSS to adjust the background-position offset. Essentially, sliding instantly from the black and white to colour images as you rollover. This technique guarentees that both images are fully loaded.
