jQuery image fade enlarge top and bottom px - javascript

I want to make the effect like, after click the box, the box disappeared after expanding its both top and bottom, I did some work, but expends only on bottom. and the effects not quite good, I'd like to make the box bigger. http://jsfiddle.net/wY8Wb/ if someone could help me out? thanks

Check this demo: http://jsfiddle.net/wY8Wb/3/
Code:
$('#videoimg').click(function(){
$(this).fadeOut('slow');
$('#color')
.css({
top: ($(this).offset().top + $(this).height()/2) + 'px',
height: 0
})
.animate({
// the hard-coded "9" you see below is half of the
// difference between the final heights of the 2 divs == (300-282)/2.
// Given here so as to have the color div expand out
// equally at top and bottom
top: ($(this).offset().top - 9) + 'px',
height: '300px'
}, 'slow');
})

JSFiddle : http://jsfiddle.net/wY8Wb/17/
$(document).ready(function(){
$('#videoimg').click(function(){
$(this).fadeOut('slow');
$('#color').animate({height: '300px', top: '0px'}, 'slow');
})
});​

Slide in from the left

This is basically my current website:
https://jsfiddle.net/s0wgnvk2/
And now I have the problem in the #About section when I click right it goes to #right section and, you can't see it in fiddle but in my webpage the transition is really smooth and I like it how it is, but I just don't know how to make it work for the left side since it is positioned left:-100%.
$(function() {
$('#About a').bind('click',function(event){
var $anchor = $(this);
$('html, body').stop().animate({
scrollLeft: $($anchor.attr('href')).offset().left
}, 1000);
event.preventDefault();
});
});
I know about the fullPage.js plugin but I'd like to have my own solution and web layout even thought fullPage is probably a lot better.
I would appreciate if you could help me out
EDIT
Fiddle corrected: https://jsfiddle.net/s0wgnvk2/1/
scrollLeft denotes the scroll bar position from the left, see ref here. So it cannot be negative (the left most position is 0).
What you need might be marginLeft, try:
$('html, body').animate({ marginLeft: '100%' });
Here is a working jsfiddle example. Note that I have make the header position: fix, so that it knows where to anchor and how to width itself when the left margin of the element changes.
Use animation not scroll
see what issue you face when you use scroll https://jsfiddle.net/kevalbhatt18/s0wgnvk2/4/
And as you said in your site animation is working smoothly and not in fiddle
that is because you haven't selected jauery from droupdown which is
present in left side of fiddle editor so your animation is not working so if you see your console it will give you Uncaught ReferenceError: $ is not defined in your example https://jsfiddle.net/s0wgnvk2/
Left right animation Example: https://jsfiddle.net/kevalbhatt18/vunL9ec2/
$('#About a').bind('click', function (event) {
var $anchor = $(this);
if ($anchor.context.innerHTML === "RIGHT" ) {
$($anchor.attr('href')).stop().animate({
left: '-=100%'
}, 1000);
} else if ($anchor.context.innerHTML === "LEFT") {
$($anchor.attr('href')).stop().animate({
left: '+=100%'
}, 1000);
} else {
console.log($(this).context.offsetParent.id )
$('#'+$(this).context.offsetParent.id ).stop().animate({
left: $(this).context.offsetParent.id ==='right'?'+=100%':'-=100%'
}, 1000);
}

scrollTop suddenly not working for sticky menu

I had this working with no problems for the entire build of the site. Then, the day I was supposed to launch, the sticky menu stopped working right. The menu is supposed to start at the bottom, scroll to the top, then stick (position: fixed).
Now, it scrolls about 10px and then jumps to the top. Why is the scrollTop distance not calculating correctly?
Live site at [site no longer exists]
Here's the code for the sticky menu. I'm also using JS to set min-height of divs to window height, but haven't included that code here.
$(function(){
var stickyRibbonTop = $('#wrapper-wcf53badf7ebadf7').offset().top;
$(window).scroll(function(){
if( $(window).scrollTop() > stickyRibbonTop ) {
$('#wrapper-wcf53badf7ebadf7').css({position: 'fixed', top: '0px', 'background-image':'url(http://amarshall.360zen.com/wp-content/uploads/2014/07/menu-fade-background2.png)'});
$('#block-bcf53bf14093931c').css({display: 'block'});
} else {
$('#wrapper-wcf53badf7ebadf7').css({position: 'static', top: '0px','background-image':'none'});
$('#block-bcf53bf14093931c').css({display: 'none'});
}
});
});
Thanks in advance for any help! I'm not a JS or jQuery expert yet, so any suggestions for cleaning things up would be appreciated.
NOTE: The site is built on WordPress, so no-conflict mode is in effect.
I think you are initialising the sticky menu function before you set the min-height of $('big-div').
On page load, the menu starts at 54px from the top, and so when you store the offset().top value as stickyRibbonTop, it is stored at 54px. Then on your scroll event you are comparing against this.
Try setting the min-height of the divs first in your code, then run this same script afterwards. The value of stickyRibbonTop should then be correct.
Bear in mind that you will need to reset stickyRibbonTop every time the window.height() is updated, so you should probably make this sticky menu function a named function and call it at the end of the wrapper_height function. something like this:
function stickyNav() {
var stickyRibbonTop = $('#wrapper-wcf53badf7ebadf7').offset().top;
$(window).unbind('scroll', scrollEvent);
$(window).on('scroll', stickyRibbonTop, scrollEvent);
};
function scrollEvent(event) {
var stickyRibbonTop = event.data;
if ($(window).scrollTop() > stickyRibbonTop) {
$('#wrapper-wcf53badf7ebadf7').css({ position: 'fixed', top: '0px', 'background-image': 'url(http://www.adammarshalltherapy.com/wp-content/uploads/2014/07/menu-fade-background2.png)' });
$('#block-bcf53bf14093931c').css({ display: 'block' });
}
else {
$('#wrapper-wcf53badf7ebadf7').css({ position: 'static', top: '0px', 'background-image': 'none' });
$('#block-bcf53bf14093931c').css({ display: 'none' });
}
};
function wrapper_height() {
var height = $(window).height();
var wrapperheight = height - 75;
wrapperheight = parseInt(wrapperheight) + 'px';
$(".bigDiv").css('min-height', wrapperheight);
$("#wrapper-wcf53bad125d7d9a").css('height', wrapperheight);
stickyNav();
}
$(function () {
wrapper_height();
$(window).bind('resize', wrapper_height);
});

$(window).scroll() not working in IE 9

I have a nav bar and a side bar that is displayed on the bottom on my page when its loaded. But as you scroll down it should add certain css to change the position of them. But seems this is not working only in IE. Can anyone tell me how to fix this in IE?
This is my code:
// SCRIPT FOR STICKY SIDEBAR AND NAV
$(function() {
var stickyRibbonTop = $('#second').offset().top;
$(window).scroll(function(){
if( $(window).scrollTop() > stickyRibbonTop ) {//background: rgba(999,999,999,0.7);height: 80px;width: 100%80
$('#stickyribbon').css({position: 'fixed', top: '0px',maxHeight:'50px',width:'100%',zIndex: '123'});
$('#sidebar').css({position: 'fixed', bottom: '26%',zIndex: '13'});
} else {
$('#stickyribbon').css({position: 'static', top: '0px'});
$('#sidebar').css({position: 'absolute', bottom: '-75%'});
}
});
});
UPDATE:
as I see now, when I log the value of $(window).scrollTop() its always 0 - zero
Try $(document).scroll instead

JS change height and return to original CSS height

Hoping to get some help on some javascript i'm getting stuck with.
Q1: JS RETURN TO IMAGE HEIGHT AND MARGIN
My layout is horizontal scroll of smaller images positioned in a grid, using different height percentages and margins to position.
When you click on any of the images they all expand to height:100% and margin:0 which clears all previous styles putting it into a simple large image layout.
My question is how do I add a function that when clicking on .image-container the height and margins returns to how it was originally set in the css
JS FIDDLE DEMO (click any center image)
// GALLERY 100% height
$('.image-container').click(function(){
$('.image-container img').animate({'height': '100%'},900)
.animate({'margin': '0'},900);
});
// ? REMOVE HEIGHT ?
$('.image-container').click(function(){
$('.image-container img').animate({'height': '?'},900)
.animate({'margin': '?'},900);
});
EDIT UPDATED QUESTION: Q2 HOW TO MAKE PAGE SIZE GROW WITH LARGER IMAGES
Right now my .image-container is set to a large width but with responsive images it's hard to find the correct width, is there a way to find this width and to make it grow along with the click grow of images (displayed above)
.image-container {
display:block;
width:3600px;
height: 75%;
float:left;
position:absolute;
top: 13%;
left: 120px;
z-index: -1;
}
Thanks for any help!
You need to store the original height in a variable.
Check out the updated fiddle
var originalheight;
// GALLERY 100% height
$('.image-container').click(function(){
originalheight = $('.image-container img').height();
$('.image-container img').animate({'height': '100%'},900)
.animate({'margin': '0'},900);
});
//REMOVE HEIGHT ?
$('.image-container').click(function(){
$('.image-container img').animate({'height': originalheight},900)
.animate({'margin': '0'},900);
});
EDIT:
Sorry about the goof up in previous solution. I didn't notice I was using click twice unnecessarily.
Here's the updated solution with the updated fiddle.
var originalheight;
$('.image-container').click(function () {
if (!originalheight) originalheight = $('.image-container img').height();
if ($('.image-container img').css('height') == originalheight + "px") { // GALLERY 100% height
$('.image-container img').animate({
'height': '100%'
}, 900).animate({
'margin': '0'
}, 900);
} else { //REMOVE HEIGHT ?
$('.image-container img').animate({
'height': originalheight
}, 900).animate({
'margin': '0'
}, 900);
}
});
This is my idea, hope it'll work:
// Before animation
var heights = new Array();
var margins = new Array();
$('.image-container img').each(function(){
heights.push($(this).css('height'));
});
$('.image-container img').each(function(){
margins.push($(this).css('margin'));
});
//
$('.image-container').click(function(){
$('.image-container img').animate({'height': '100%'},900)
.animate({'margin': '0'},900);
});
// ? REMOVE HEIGHT ?
$('.image-container').click(function(){
$('.image-container img').animate({'height': heights[$(this).index()]},900)
.animate({'margin': margins[$(this).index()]},900);
});
First of all, I suggest you to use the focusout and blur event to undo changes, because the way you implement your 'click' event, the second part only will be considered (you erase the first click implementation doing so). the best thing, is to enlarge the image when clicked, and reinit it's size when you click away.
Try this :
// GALLERY 100% height
$('.image-container')
.bind('click', function(){
$('.image-container img').animate({height: '100%'},900)
.animate({margin: 0},900);
})
.bind('focusout blur', function(){
$('.image-container img').animate({height: ''},900)
.animate({margin: ''},900);
});
Or better, use classes in which you define the behaiviors on clicking, and on clicking again, for exemple :
<style>
.clickimage{ height : 100%; margin :0;}
.yourOriginalValues {height : original; margin : original;}
</style>
$('.yourOriginalValues').click(function(){
$(this).switchClass( "yourOriginalValues", "clickimage", 900 );
});
$('.clickimage).click(function(){
$(this).switchClass( "clickimage", "yourOriginalValues", 900 );
});
ps. the switchClass method, is a jQuery UI functionality.

How to animate the width of a div slowly with jquery

I have navigation nested in a div that is offscreen to the left and when the user scrolls down the page and reaches pixel 296, the left navigation slowly appears by it's width growing towards the right.
What I have now is half working. The navigation nested in the div appears when the user scrolls down the page but I want it to animate slowly to the right and that is not happening. Not sure what I am doing wrong. The specific line I am having problems with is:
$("#slidebottom").animate({ width: "100" }, 'slow');
But here is my entire code:
$(window).scroll(function(){
var wintop = $(window).scrollTop(), docheight = $(document).height(),
winheight = $(window).height();
var bottomHeight = $("#slidebottom").height();
var zeroheight = 0;
if  (wintop > 296) {
bottomHeight = $('#slidebottom').height(docheight);
$("#slidebottom").animate({ width: "100" }, 'slow');
}
if( wintop < 296)
{
bottomHeight = $('#slidebottom').height(zeroheight);
//$("#slidebottom").animate({ width: "0" }, 'slow');
}
});
The jQuery docs show ints, not strings, as the arguments to width:
$("#slidebottom").animate({ width: 100 }, 'slow');
Edit: So I was wrong, that's not the problem; it handles strings just as well.
Try the following maybe?
$("#slidebottom").animate({ width: '100px' }, 'slow');
I have a feeling that the unit is important for this, since 100 can mean anything. Not very specific. And you can define this as a string just fine. In fact, in the example they give for .animate it is defined as a string.
