I've worked with this many times and have had no problem. Animating the height and/or width of a DIV either by width/height: 'toggle' or replacing 'toggle' with specified width/height.
setTimeout( function(){
$('.input-group .Advanced').animate({
height: 'toggle'
}, {
duration: 500,
});
} , 500);
height: 'toggle' - Demo on JSFiddle
height: '400px' - Demo on JSFiddle
The code snippet works perfectly fine however I need this to be set to a specific height and replacing my 'toggle' to a fixed height such as '400px' does absolutely nothing...
$('.form-control' ).click(function(e) {
$(this).addClass('InputFreezeFocus');
$(this).animate({
width: '400px'
}, {
direction: 'left',
duration: 500,
});
setTimeout( function(){
$('.input-group .Advanced').animate({
height: '400px',
opacity: 'toggle'
}, {
duration: 500,
});
} , 500);
});
The .animate() method does not make hidden elements visible as part of the effect so you have to toggle the opacity.

Your given height is not working because you have set a display:none to your .Advanced class. When you use jquery inbuilt toggle string it will take care of that and make your hidden element in view.But, when you define your own height you also have to display that element in view otherwise animation will work but not display. You can refer Jquery animate() reference .It's written there
Note: Unlike shorthand animation methods such as .slideDown() and .fadeIn(), the .animate() method does not make hidden elements visible as part of the effect. For example, given $( "someElement" ).hide().animate({height: "20px"}, 500), the animation will run, but the element will remain hidden.
You can do this to animate your class
setTimeout( function(){
$('.input-group .Advanced').animate({
height: '500px',
opacity:'show'
}, {
duration: 500
});
} , 500);
This will get your hidden element in view.Demo of your code

I'm working on what I thought would be a simple chunk of code, trying to dynamically (using 'this') animate div blocks to scale (zoom) to the size of the parent container (section tag) on click.
My HTML:
<section>
<div id="project"></div><div id="project"></div><div id="project"></div>
<div id="project"></div><div id="project"></div><div id="project"></div>
</section>
My JavaScript:
$("#project").click(function() {
$(this).animate({
opacity: 0.75,
width: 100%,
height: 100%
}, 5000, function() {
});
});
Both Jquery and Jquery UI are linked correctly from Google Libraries (so says my console), my console also tells me that there is a syntax error with an unexpected ",", however I am taking this syntax straight from JqueryUI.com. Any help is appreciated!
Additionally, I want to be able to dynamically select all other divs except the currently clicked div and remove them from the DOM (using display:none), just so it looks cleaner, but I don't know how to go about 'selecting' them in my code...
Thanks all! :)
you are missing quotes around 100% so your code will be correct like this
$("#project").click(function() {
$(this).animate({
opacity: 0.75,
width: "100%",
height: "100%"
}, 5000, function() {
});
and please use unique IDs
Edit:
for using classes you can use something like that
$(".project").click(function() {
$(".project").css({'display':'none'});
$(this).css({'display':'block'});
$(this).animate({
opacity: 0.75,
width: "100%",
height: "100%"
}, 5000, function() {
});
I want to be able to dynamically select all other divs except the currently clicked div and remove them from the DOM (using display:none), just so it looks cleaner, but I don't know how to go about 'selecting' them in my code...
var $project = $(".project");
$project.click(function() {
var thisDiv = this;
$project.each(function(index, elem) {
if (elem!==thisDiv) $(elem).css('display', 'none');
});
$(thisDiv).animate({
opacity: 0.75,
width: "100%",
height: "100%"
}, 5000, function() {});
});
I have here a function and what I want to happen is to display the div first before it smoothly changes it's width.. Unfortunately what happen is that the width already changes once it appears
CSS:
#frame12{
opacity:0;
filter:alpha(opacity=0);
width:100;
}
jQuery:
function animatestamp(){
jQuery("div#frame12").css({'opacity':'1','filter':'alpha(opacity=100)'}).animate({
width:'451px'
},animatestamp);
}
Use animate on div's opacity first and then on its complete callback animate the width.
function animatestamp() {
jQuery("#frame12").animate({ //animate the opacity first
'opacity': 1,
'filter': 'alpha(opacity=100)'
}, 2000, function () { //Once it is completely visible start animating the width
$(this).animate({
'width': '451px',
}, 1000);
});
}
animatestamp();
Fiddle
For recursive you can try this:
var $frame = jQuery("#frame12");
function getWidthConfig(elem) { //get the width animate object based on current elem width
return {
'width': elem.width() > 450 ? '100px': '451px'
}
}
function getOpacityConfig(elem) {//get the opacity animate object based on current elem opacity
var opac = +elem.css('opacity');
return {
'opacity': !opac ? 1 : 0,
'filter': !opac ? 'alpha(opacity=100)' : 'alpha(opacity=0)'
}
}
function animatestamp() {
$frame.animate(getOpacityConfig($frame), 2000, function () {
$frame.animate(getWidthConfig($frame), 1000, animatestampReverse);
});
}
function animatestampReverse() {
$frame.delay(2000).animate(getWidthConfig($frame), 1000, function () {
$frame.animate(getOpacityConfig($frame), 2000, animatestamp)
});
}
animatestamp();
Fiddle
Animate opacity & filter first, then animate the width as PSL well said but also in your CSS, change "width:100;" to "width:100px;" (Add measurement unit "px") or otherwise the div's initial width would be screen width (add a border to your css to see the difference visually) and to make your js simpler and more readable, use chaining in your Javascript:
CSS:
#frame12{
opacity:0;
filter:alpha(opacity=0);
width:100px; /*Add px to avoid max screen witdth and CSS Flash */
border: solid 1px; /* to see the real div width */
}
Javascript:
function animatestamp() {
$("div#frame12")
.animate({ 'opacity': 1, 'filter': 'alpha(opacity=100)' }, 2000)
.animate({ width: '451px'}, 1000);
}
Need more code to be sure, but I'm guessing its because you have not set an explicit width on that container before applying an animation to the width property. Could try this:
function animatestamp(){
$("#frame12").css({
'opacity':'1',
'filter':'alpha(opacity=100)',
'width': $(this).width()
}).animate({
width:'451px'
}, animatestamp);
}
Or just set it in the css...
#frame12 { width: 100px; }
... and remove the 'width' from the css() above.
I am using zepto library for my mobile web site. I have recently learnt that zepto does not have slideDown() plugin like jquery. I would like to implement the same for zepto.
I have tried one on jsfiddle (http://jsfiddle.net/goje87/keHMp/1/). Here it does not animate while showing the element. It just flashes down. How do I bring in the animation?
PS: I cannot provide a fixed height because I would be applying this plugin to the elements whose height property would not be known.
Thanks in advace!!
Demo: http://jsfiddle.net/6zkSX/5
JavaScript:
(function ($) {
$.fn.slideDown = function (duration) {
// get old position to restore it then
var position = this.css('position');
// show element if it is hidden (it is needed if display is none)
this.show();
// place it so it displays as usually but hidden
this.css({
position: 'absolute',
visibility: 'hidden'
});
// get naturally height
var height = this.height();
// set initial css for animation
this.css({
position: position,
visibility: 'visible',
overflow: 'hidden',
height: 0
});
// animate to gotten height
this.animate({
height: height
}, duration);
};
})(Zepto);
$(function () {
$('.slide-trigger').on('click', function () {
$('.slide').slideDown(2000);
});
});
This worked for me:
https://github.com/Ilycite/zepto-slide-transition
The Zepto Slide Transition plugin add to Zepto.js the functions bellow :
slideDown();
slideUp();
slideToggle();
Speransky's answer was helpful, and I'm offering a simplified alternative for a common drop-down navigation list, and separated into slideUp and slideDown on jsfiddle: http://jsfiddle.net/kUG3U/1/
$.fn.slideDown = function (duration) {
// show element if it is hidden (it is needed if display is none)
this.show();
// get naturally height
var height = this.height();
// set initial css for animation
this.css({
height: 0
});
// animate to gotten height
this.animate({
height: height
}, duration);
};
This would work for what you need:

I have a div with hight 300px
I want to use slideDown or any of jquery methods to slide down a part of the div not all the 300px
may be just 50px
Try this DEMO
$('#clickme').click(function() {
$('#book').animate({
top: '+=50',
height: '-=50'
}, 1000, function() {
// callback on complete.
});
});
$("#your_div").scrollTop(50)
isn't it right?
I have found jQuery: FadeOut then SlideUp and it's good, but it's not the one.
How can I fadeOut() and slideUp() at the same time? I tried two separate setTimeout() calls with the same delay but the slideUp() happened as soon as the page loaded.
Has anyone done this?
You can do something like this, this is a full toggle version:
$("#mySelector").animate({ height: 'toggle', opacity: 'toggle' }, 'slow');
For strictly a fadeout:
$("#mySelector").animate({ height: 0, opacity: 0 }, 'slow');
Directly animating height results in a jerky motion on some web pages. However, combining a CSS transition with jQuery's slideUp() makes for a smooth disappearing act.
const slideFade = (elem) => {
const fade = { opacity: 0, transition: 'opacity 400ms' };
elem.css(fade).slideUp();
};
slideFade($('#mySelector'));
Fiddle with the code:
https://jsfiddle.net/00Lodcqf/435
In some situations, a very quick 100 millisecond pause to allow more fading creates a slightly smoother experience:
elem.css(fade).delay(100).slideUp();
This is the solution I used in the dna.js project where you can view the code (github.com/dnajs/dna.js) for the dna.ui.slideFade() function to see additional support for toggling and callbacks.
The accepted answer by "Nick Craver" is definitely the way to go. The only thing I'd add is that his answer doesn't actually "hide" it, meaning the DOM still sees it as a viable element to display.
This can be a problem if you have margin's or padding's on the 'slid' element... they will still show. So I just added a callback to the animate() function to actually hide it after animation is complete:
$("#mySelector").animate({
height: 0,
opacity: 0,
margin: 0,
padding: 0
}, 'slow', function(){
$(this).hide();
});
It's possible to do this with the slideUp and fadeOut methods themselves like so:
$('#mydiv').slideUp(300, function(){
console.log('Done!');
}).fadeOut({
duration: 300,
queue: false
});
I had a similar problem and fixed it like this.
$('#mydiv').animate({
height: 0,
}, {
duration: 1000,
complete: function(){$('#mydiv').css('display', 'none');}
});
$('#mydiv').animate({
opacity: 0,
}, {
duration: 1000,
queue: false
});
the queue property tells it whether to queue the animation or just play it right away
Throwing one more refinement in there based on #CodeKoalas. It accounts for vertical margin and padding but not horizontal.
$('.selector').animate({
opacity: 0,
height: 0,
marginTop: 0,
marginBottom: 0,
paddingTop: 0,
paddingBottom: 0
}, 'slow', function() {
$(this).hide();
});
