how to animate height of a div back-jquery - javascript

I'm trying to show some part of a div and animate it to 100% when the div is clicked.
and I want to animate it back to the initial height of the div if it's clicked again.
this is what i have so far,but it doesn't work. can anyone help?
#mydiv {
height:150px;
width: 100%;
overflow:hidden;
}
<script type="text/javascript">
$(document).ready(function(){
$("#mydiv").click(function(){
$(this).animate({height: '100%'}, 300);
}, function() {
$(this).animate({height: '150px'}, 300);
});
});
</script>

click() doesn't accept two function arguments, previously there was a toggle() function that performed how you need it but it has now been deprecated and removed from jQuery.
Since your use case is pretty simple, I believe something like this would be enough:
$("#mydiv").click(function () {
var $this = $(this);
$this.animate({
height: $this.height() == 150 ? '100%' : 150
}, 300);
});
Demo fiddle

This should do the job for you.
jQuery:
$(document).ready(function() {
$("#mydiv").toggle(
function() {
$(this).animate({height: '100%'}, 300);
};
function() {
$(this).animate({height: 150}, 300);
});
});

Following jQuery isn't working. Take a look

Code:
<div>
Back
<div class="outer"></div>
Next
</div>
<div>
Back
<div class="outer"></div>
Next
</div>
jQuery code:
$('.next').click(function() {
$('.next').prev().animate({
scrollLeft: '+=150'
}, 200);
});
$('.back').click(function() {
$('.back').next().animate({
scrollLeft: '-=150'
}, 200);
});
Error:
Basically I have more codes with the same classes as above and I want to scroll the code which is clicked. But the code written above scroll all the ".outer" on the page. Each set of the code is in different div. The inside material of the "outer" isn't provided which is scroll able.
You need to execute the code using current element context i.e. this. Also animate the siblings of parent element so traverse up using $(this).closest('div') then use .prev() or next()
$(function() {
$('.next').click(function() {
$(this).closest('div').prev().animate({
scrollLeft: '+=150'
}, 200);
});
$('.back').click(function() {
$(this).closest('div').next().animate({
scrollLeft: '-=150'
}, 200);
});
});
Simple Use $(this) for get current Object
$('.next').click(function () {
$(this).prev().animate({ scrollLeft: '+=150'}, 200);
});
$('.back').click(function () {
$(this).next().animate({ scrollLeft: '-=150'}, 200);
});
Don't forget to wrap your code in a document ready function.
<script>
$(document).ready(function() {
$('.next').click(function () {
$(this).prev().animate({ scrollLeft: '+=150'}, 200);
});
$('.back').click(function () {
$(this).next().animate({ scrollLeft: '-=150'}, 200);
});
});
</script>
Also using the on method is better for event binding, e.g.
<script>
$(document).ready(function() {
$('.next').on('click', function () {
$(this).prev().animate({ scrollLeft: '+=150'}, 200);
});
$('.back').on('click', function () {
$(this).next().animate({ scrollLeft: '-=150'}, 200);
});
});
</script>
Edit:
As #GuruprasadRao pointed out, I'm assuming you are already but make sure you're using a HTML5 doctype otherwise you'll need to add type="text/javascript" to your script tag.

jquery stop() doesn't work properly

I have some DIVs for products, and I have:
// mouseenter
$(document).on('mouseenter', '.productWrapper', function(){
$(this).stop(true,true);
$(this).find('.productWrapperContentVisible').animate({
height: '100px',
opacity: '1',
}, function(){
$(this).find('.productWrapperPrice').fadeIn();
$(this).find('.productWrapperByCompany').fadeIn();
});
});
// mouseleave
$(document).on('mouseleave', '.productWrapper', function(){
$(this).stop(true,true);
$(this).find('.productWrapperPrice').fadeOut('fast');
$(this).find('.productWrapperByCompany').fadeOut('fast');
$(this).find('.productWrapperContentVisible').animate({
height: '40px',
opacity: '.8',
});
});
and there are about 20 of products in each page, while I'm using stop(true,true), after I move my mouse on many of them many times, this doesn't work right, they continue to change height, and sometimes productWrapperPrice is still there while I don't have my mouse over there, it should go hidden.. .
sample: http://jsfiddle.net/gwsPB/
What's wrong with my code?
Thanks
Try this:
// mouseenter
$(document).on('mouseenter', '.productWrapper', function () {
$(this).find('.productWrapperContentVisible').stop(true, false).animate({
height: '100px',
opacity: '1'
}, function () {
$(this).find('.productWrapperPrice, .productWrapperByCompany').stop(true, true).fadeIn();
});
}).on('mouseleave', '.productWrapper', function () {
var $this = $(this);
$this.find('.productWrapperPrice, .productWrapperByCompany').stop(true, true).fadeOut('fast');
$this.find('.productWrapperContentVisible').stop(true, false).animate({
height: '40px',
opacity: '.8'
});
});
DEMO
The problem is: when you mouseenter and mouseleave immediately fast enough, your animate function in the mouseenter event is not finished yet. When your call $this.find('.productWrapperContentVisible').stop(true, true), the animation is stopped but the callback function is called which display them again
function () {
$(this).find('.productWrapperPrice, .productWrapperByCompany')
.stop(true, true).fadeIn();
}
By using stop(true, false), the callbacks are not called.
You need to call stop() on elements where are being animated, calling it on an ancestor element has no effect.
// mouseenter
$(document).on('mouseenter', '.productWrapper', function () {
$(this).find('.productWrapperContentVisible').stop(true, true).animate({
height: '100px',
opacity: '1'
}, function () {
$(this).find('.productWrapperPrice, .productWrapperByCompany').stop(true, true).fadeIn();
});
}).on('mouseleave', '.productWrapper', function () {
var $this = $(this);
$this.find('.productWrapperPrice, .productWrapperByCompany').stop(true, true).fadeOut('fast');
$this.find('.productWrapperContentVisible').stop(true, true).animate({
height: '40px',
opacity: '.8'
});
});

How to bind mouseover event after unbinding it?

I'm trying to get a nice animation with jQuery. I came up with that code:
$(document).ready(function () {
$('#arrow_up').hide();
$('#arrow_down').bind({
mouseenter: function() {
$('#content')
.animate({
height: '110px'},
300);
},
mouseleave: function() {
$('#content')
.animate({
height: '100px'},
300);
}})
.click(function() {
$(this)
.fadeOut( 1000 )
.unbind('mouseenter')
.unbind('mouseleave');
$('#content')
.animate({
height: '300px'},
500);
$('#arrow_up')
.delay(1000)
.fadeIn( 2000 );
});
$('#arrow_up').bind({
mouseenter: function() {
$('#content')
.animate({
height: '290px'},
300);
},
mouseleave: function() {
$('#content')
.animate({
height: '300px'},
300);
}})
.click(function() {
$(this)
.fadeOut( 1000 )
.unbind('mouseenter')
.unbind('mouseleave');
$('#content')
.animate({
height: '100px'},
500);
$('#arrow_down')
.delay(1000)
.fadeIn( 2000 );
});
});
It is working nicely, but only the first time. You can check it here: http://www.cow-art.eu/test/index.html
I want to animate the content div on hovering an arrow below. After clicking it I want to slide it down to full size and after the next click - to hide it partially. You can check it on the link provided above. It's working fine, but the arrow hovering animation is working unless I show and hide the content. The second approach is not animating it as the first.
I assume it's because the clicking event is unbinding the mouseenter and mouseleave, and there is no other event what can bind it again.
I ran out of ideas how to fix it. Can you please help me with that one?

.animate() to add margin

I am using the code to add margin to a div on click. It works perfectly, but I want to make it "animate" when it is adding margin for a sliding effect. How would I use .animate() to accomplish this?
<script type='text/javascript'>
$(document).ready(function () {
$('.menub').click(function() {
if ($('.content').css('margin-left') == '300px')
{
$('.content').css('margin-left', '0px');
}
else {
$('.content').css('margin-left', '300px');
}
});
$('.navigation a li').click(function() {
$('.content').css('margin-left', '0px');
});
});
</script>
Do this:
​$('.content').animate({marginLeft: 300}, 1000);​​​​​
where 300 is the left margin width and 1000 is the number of milliseconds to animate. Apply same logic to do the reverse animation. See http://api.jquery.com/animate/ for more info.
<script type='text/javascript'>
$(document).ready(function () {
$('.menub').click(function() {
if ($('.content').css('margin-left') == '300px')
{
$('.content').animate({'margin-left', '0px'},5000);
}
else {
$('.content').animate({'margin-left', '300px'},5000);
}
});
$('.navigation a li').click(function() {
$('.content').animate({'margin-left', '0px'},5000);
});
});
</script>
Refrence: http://api.jquery.com/animate/
Like this: (the key is to use the JavaScript property "marginLeft")
$('.content').animate({
marginLeft: '+=50'
}, 5000, function() {
});

Make a DIV reveal upwards onClick

I found a topic for revealing a DIV upwards but as I am no Javascript expert, I am wondering how I can make this work onClick rather than on hover?
Just in case this helps, the link to previous topic is: How to make jQuery animate upwards
Any help is appreciated.
Here is a sample demo
$("#slideToggle").click(function () {
$('.slideTogglebox').slideToggle();
});
$("#reset").click(function(){
location.reload();
});
​
HTML:
<button id=slideToggle>slide</button>
<br/>
<div class="slideTogglebox">
slideToggle()
</div>
$(document).ready(function() {
var isClicked = false; //assuming its closed but its just logic
$('.button').click(function() {
if (isClicked) {
isClicked = true;
$(this).closest('div').animate({
height: "150px",
}, 400, "swing");
}
else
{
isClicked = false;
$(this).closest('div').animate({
height: "50px",
}, 400, "swing");
}
});
});
This is pretty bad way of doing it any way. You should consider trying to use CSS3 instead and then jsut using jQueries toggleClass
.toggleClass('animateUpwards)
Lets the browser use hardware capabilities to animate all the stuff and also its a nice one liner in JavaScript.
Try jQuery slideUp or as posted elsewhere jQuery slideToggle - Alternatively CSS3 Example
or from the questions you posted, perhaps this is what you meant:
http://jsbin.com/ogaje
Clicking the (visible part of) the div
$(document).ready(function() {
$('.featureBox').toggle(function() {
$(this).animate({top: '-390px', height:'540px'},{duration:'slow', queue:'no'});
// or $(this).slideUp()
},
function() {
$(this).animate({top: '0px', height:'150px'},{duration:'slow', queue:'no'});
// or $(this).slideDown()
});
});
Clicking something else
$(document).ready(function() {
$("#button").toggle(function() {
$("#someDiv").animate({top: '-390px', height:'540px'},{duration:'slow', queue:'no'});
// or $("#someDiv").slideUp()
},
function() {
$("#someDiv").animate({top: '0px', height:'150px'},{duration:'slow', queue:'no'});
// or $("#someDiv").slideDown()
});
});
