I am trying to make a div that expands in height when clicked on, and then goes back to its original size when clicked on again. I have tried to use .toggle but whenever I do every div (with the related class) completely vanishes. I posted a code pen below so you can easily view the codes effects.
http://codepen.io/JoshuaHurlburt/pen/JKqAPr
<div>
<div class='box' id='emailVer'>
<h2 id='payText'>PAYMENT</h2>
</div>
<div class='box' id='accCust'>
<h2 id='acText'>ACCOUNT CUSTOMIZATION</h2>
</div>
<div class='box' id='pay'>
<h2 id='evText'>EMAIL VERIFICATION</h2>
</div>
</div>
JS:
var main = function(){
$('.box').click(function() {
$(this).animate({
height: "300px"
},200 );
}
)}
$(document).ready(main);
I decided to leave out the CSS, but I will edit it in if anyone thinks it is important to the solution
There's probably a better solution than this but here is one-
Replace your script file with this
var main = function(){
$('.box').click(function() {
var el = $(this);
if (!el.hasClass('selected')) {
el.animate({
"height": "300px"
}, 200)
el.addClass("selected");
} else {
el.animate({
"height": "75px"
}, 200);
el.removeClass("selected");
}
}
)}
$(document).ready(main);
What you need is a way to track what has already been selected (and animated) and what has not. I chose to add a class (selected) and check to see if the element has that class. If it has not yet been selected, animate to 300px and add the class, else animate back to 75px and remove it.
Try .slideToggle
$( "#clickme" ).click(function() {
$( "#book" ).slideToggle( "slow", function() {
// Animation complete.
});
});
The toggle functions in jQuery toggle the visibility of an element which is why they disappear.
I believe what you are looking for is .toggleClass. See http://api.jquery.com/toggleclass/. You can then create another class with the expanded height properties. Which will be toggled on and off on click.
Adding height to your existing transition property on box will handle the animation.
CSS
.box {
width:300px;
height:75px;
margin:0 auto;
-webkit-transition:box-shadow 1s, height 1s;
transition: box-shadow 1s, height 1s;
}
.expanded {
height: 300px;
}
JS
var main = function(){
$('.box').click(function() {
$(this).toggleClass('expanded');
}
)};
$(document).ready(main);

I would like to make a Text run from left to right in a loop. Here is the fiddle with my attempt:
https://jsfiddle.net/9Lruxym8/33/
I started with css #keyframes but I think I need the width of the text itself if I want the text to run seamlessly. My idea was to write down the text two times and once the div with the texts has run exactly halfway, the animation starts again.
After #keyframes didn't work, I tried jQuery animation. It did work somewhat but didn't run smoothly. Now I'd like to do it via transition. I thought a combination of intervals and timeouts could do the trick but I still don't get it to work - and now, I don't know why. Does anyone have a hit for me?
function runText() {
var text_width = $('#runningP').width()/2;
console.log(text_width)
setInterval(function(){
console.log("interval");
$('.text').css({'transition':'margin-left 5s'});
$('.text').css({'margin-left':'-' + text_width + 'px'});
moveBack();
}, 3000);
function moveBack() {
console.log("timeout")
setTimeout(function(){
$('.text').css({'transition':'none'});
$('.text').css({'margin-left': 0});
}, 3000);
}
}
runText();
I've recently made a bit of custom code for this functionality.
Looking at my code, it seems a bit much having essentially 3 "levels" (.scrollTextWrap > .scrollingText > .scrollContent) but this was the structure I ended up using to get a clean and consistent effect.
I've added in an initialiser too so that you could simply add the scrollMe class and have them setup the html for you
In the snippet I've added a .parentContainer purely to show how it works when constrained
$(document)
.ready(function(){
// check that scrollingText has 2 scrollContent element
$('.scrollMe')
.each(function(){
initScrollingText($(this));
});
});
function initScrollingText($this){
// store text
var text = $this.text();
// empty element
$this.html(null);
var $wrap = $('<div class="scrollTextWrap" />'),
$text = $('<div class="scrollingText" />'),
$content = $('<div class="scrollContent" />');
// set content value
$content.text(text);
// duplicate content
$text
.append($content)
.append($content.clone());
// append text to wrap
$wrap.append($text)
// add $wrap to DOM
$wrap.insertAfter($this);
// remove old element
$this.remove();
}
/* to simulate width constraints */
.parentContainer {
width: 140px;
position:relative;
overflow:hidden;
}
.scrollTextWrap {
position:relative;
width:auto;
display:inline-block;
}
.scrollingText {
display: flex;
position:relative;
transition:left 0.1s;
animation: scrollText 5s infinite linear;
}
.scrollContent {
white-space: nowrap;
padding-right:5px;
}
#keyframes scrollText {
0% { left:0 }
100% { left:-50% }
}
<div class="parentContainer">
<div class="scrollMe">Content you want to scroll goes here</div>
<!-- alternatively you can just structure the html -->
<div class="scrollTextWrap">
<div class="scrollingText">
<div class="scrollContent">Content you want to scroll goes here</div>
<div class="scrollContent">Content you want to scroll goes here</div>
</div>
</div>

I have a problem I need help with as I am a bit new to Jquery, what I have is a button which is half hidden at the left side of the screen and a menu which is completely hidden from view also at the left side, what I am trying to achieve is, on mobile the user would 'tap' the button which would slide from the side to reveal the full button for which then you would tap the button again which would then slide the menu out from its hidden position on the left. The problem I am having is no matter which approach I take, whenever I tap the half hidden button, it will slide out but then the menu slides out straight away without having to tab the button a second time so if any of you kind folk could point me in the right direction I would really appreciate it.
Here is my code:
$( "#catbutt" ).on("tap",function(e) {
$( "#catbutt" ).animate({left: "0px"},300,'swing');
});
$( "#catbutt" ).on("tap",function(e) {
$( "#categories" ).animate({left: "0px"});
});
Maybe something like this, where you check the #catbutt element's left position, and if it's already 0px, slide out the #categories element, otherwise, just slide out the #catbutt element (heh. catbutt.) :
$( "#catbutt" ).on("tap",function(e) {
if($(this).css('left') == '0px') {
$( "#categories" ).animate({left: "0px"});
}
else {
$(this).animate({left: "0px"}, 300, 'swing');
}
});
You're still going to have to get it to close, too. Here's a Fiddle with it having three stages... the first is the button expanding, the second is the menu expanding, and the third is both the button and menu collapsing: https://jsfiddle.net/wcvg3nby/
Here's the pertinent code from the Fiddle:
CSS
#catbutt {
width: 100px;
height: 20px;
position: fixed;
left: -80px;
background-color: red;
}
#categories {
width: 100px;
position: fixed;
left: -100px;
}
HTML
<div id='catbutt'></div>
<div id='categories'>
<div>Cat 1</div>
<div>Cat 2</div>
<div>Cat 3</div>
<div>Cat 4</div>
</div>
JS
$('#catbutt').on('click', function() {
if($(this).offset().left < 0) {
$(this).animate({'left':'0px'});
}
else if($(this).offset().left == 0) {
$(this).animate({left: '100px'});
$('#categories').animate({left: '0px'});
}
else {
$(this).animate({left: '-80px'});
$('#categories').animate({left: '-100px'});
}
});
This is my first question here, feel free to tell me if I am not specific enough or whatever I do wrong!
I want a jquery method which change all divs with the class "passive" to height 500 px and passive-->active, so there would be another method which changes the height back to 100px. The first half is working, I got the class changed, but the second animation won't happen. All I have in html is one div with the class of passive.
$("document").ready(function(){
$(function() {
$(".passive").click(function(){
$(this).animate({height:'500px'});
$(this).addClass("active");
$(this).removeClass("passive");
});
$(".active").click(function(){
$(this).animate({height:'100px'});
$(this).addClass("passive");
$(this).removeClass("active");
});
});
});`
jQuery.animate() is costly and choppy. You will get a smoother transition by just toggling the class and using CSS to transition
.passive {
height:100px;
transition:height 1s;
}
.active {
height:300px;
}
Array
.from(document.querySelectorAll('.passive'))
.forEach(
e => e.addEventListener(
'click',
evnt => e.classList.toggle('active')
)
)
.container { display:flex; }
.container>div {
flex:1 auto;
}
.passive {
background-color:red;
margin:5px;
height:100px;
width:20px;
transition:height 1s;
}
.active {
height:300px;
}
<div class="container">
<div class="passive" tabindex=1></div>
<div class="passive" tabindex=2></div>
<div class="passive" tabindex=3></div>
</div>
You are trying to interact with a class added after the DOM loaded. By default, click functions will only work with elements that exist on load. You can either use event delegation or add a base class to the element. If you add a base class, you can simplify the click function.
You can do an if/else to check if the element has a certain class using hasClass. Also, you can chain together the $(this) methods inside the if/else blocks.
$("document").ready(function() {
$(function() {
$("baseclassname").click(function() {
if ($(this).hasClass('passive')) {
$(this).animate({ height: '500px' });
$(this).addClass("active");
$(this).removeClass("passive");
// $(this).animate({ height: '500px' }).addClass('active').removeClass('passive');
} else {
$(this).animate({ height: '100px' });
$(this).addClass("passive");
$(this).removeClass("active");
// $(this).animate({ height: '100px' }).addClass('passive').removeClass('active');
}
});
});
});
I have some code here and cannot find out how to make this work because I am still really new to javascript and jquery. I will have a demo below so you can see what I have going on. In the demo there is div positioned left:-60px so it is hidden, this div also has class of 'show' which positions the div to left:0 There is also the long black box which is another div. I want to make it so when you hover over the long black box, it will activate the 'show' property of the other div. Here is my code:
var $showSidemenu = $('#sidemenu');
var $sidemenuShowButton = $('#sidemenuShowButton');
function(showSidemenu){
$showSidemenu.onmouseover($sidemenuShowButton).addclass('show');
}
#sidemenuShowButton {
width:60px;
height:100%;
background:#000000;
top:0;
left:0;
position:fixed;
}
#sidemenu {
width: 60px;
height:100%;
background-color: #383D3F;
position: fixed;
top: 0;
left:-60px;
float: left;
z-index:0;
}
#sidemenu.show {
left: 0;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div id="sidemenuShowButton"></div>
<div id="sidemenu"></div>
try this jQuery:
var $showSidemenu = $('#sidemenu');
var $sidemenuShowButton = $('#sidemenuShowButton');
$(document).ready(function(){
$sidemenuShowButton.on('mouseover',function(){
$('#sidemenu').addClass("show");
});
$sidemenuShowButton.on('mouseout',function(){
$('#sidemenu').removeClass("show");
});
// to make the showed div stay while the mouse is still over it
$('#sidemenu').on('mouseover',function(){
$(this).addClass("show");
});
$('#sidemenu').on('mouseout',function(){
$(this).removeClass("show");
});
});
if you want a little animation, you can use CSS3 Transition for that, like this one:
#sidemenu {
transition: 1s;
}
HERE'S A WORKING DEMO
Use JQuery's show and hide functions. If you set your #sidemenu to display: none;. And then use this this function it will work:
$('#sidemenu').mouseenter(function(){
$("#sidemenuShowButton").show();
}).mouseleave(function(){
$("#sidemenuShowButton").hide();
});
No classes are needed in this way.
Your JS should looks like this:
var $showSidemenu = $('#sidemenu');
var $sidemenuShowButton = $('#sidemenuShowButton');
$sidemenuShowButton.on('mouseover', function(){
$showSidemenu.addClass('show')
});
First of all you are using function which never used and cannot be used since it have no name. Second, there is no onmouseover method in jQuery (read the manual ;-). Third you have to pass there a callback function which will be involved when 'mouseover' event occurs.
And if you wanna hide your div when mouse leaves add
$showSidemenu.on('mouseleave', function(){
$showSidemenu.removeClass('show')
});
You should use $showSidemenu in this case instead of $sidemenuShowButton because when $showSidemenu apears mouse leaves $sidemenuShowButton and enters $showSidemenu. But if you wanna use css3 animation - it's better to make appearing div nested to control div and use event bobbling.
And jsfiddle
Solution:Use mouseover and mouseout events to add and remove class "show"
I have intentionally added mouseout event on showSidemenu as when it slides in it goes over sidemenuShowButton div and comes on top of it, so attaching mouseout to sidemenuShowButton will cause flickering effect.
http://api.jquery.com/category/events/mouse-events/
$sidemenuShowButton.mouseover(function(){
$showSidemenu.addClass("show");
}
);
$showSidemenu.mouseout(function(){
$showSidemenu.removeClass("show");
}
);
Working JS Fiddle Example: http://jsfiddle.net/2cjjdm7j/1/
I'm totally new in js and jq. I'am trying force my #cont div to change height on hover with animation and back to previous height without hover, but I dont know how to achieve that. In my test it should make an alert (or make other function), right?
http://jsfiddle.net/JJh9z/1773/
<div id='cont'>
<ul>
<li>an item</li>
<li>an item</li>
<li>an item</li>
<li>an item</li>
<li>an item</li>
</ul>
<div id='ruch'>HOVER</div>
</div>
#cont {
border: 1px solid #000;
height: 200px;
overflow:hidden;
position:relative;
}
#ruch {
position:absolute;
bottom:0px;
}
var result = $("#cont").height();
$('#ruch').hover(function(){
$('#cont').animate({height:'300px'}, 500);
});
if (result == 300) {
alert(result)
}
Your if statement only runs once when the script is first loaded, so no it won't alert each time someone hovers. it is not an event listener.
You need to add another event listener for when the mouse leaves the element (mouseout). See this modified code:
$('#ruch').hover(function(){
$('#cont').animate({height:'300px'}, 500);
});
$('#ruch').mouseout(function(){
$('#cont').animate({height:'200px'}, 500);
});
http://jsfiddle.net/JJh9z/1775/
http://api.jquery.com/hover/
You can specify a handleout event handler, in which you'd restore the element to its previous height.
You also should select not the 'HOVER' div (it's small) but a bigger element (like cont):
$('#cont').hover(
function () {
$('#cont').animate({
height: '300px'
}, 500);
},
function () {
$('#cont').animate({
height: '200px'
}, 500);
});
Here, I've specified a hover-out handler, and focused on 'cont' instead of 'ruch'
http://jsfiddle.net/JJh9z/1773/
There are several ways of doing this. One is to call the 'after animation completes function'. which takes another function as option.. the below example alerts 'Hii' after animating the height to 300px.
$( "#ruch").hover(function() {
$( "#cont" ).animate({
height: "300px"
}, {
duration: 500,
complete: function() {
alert('Hii');
}
});
});
To prevent multiple animations for one hover event since #ruch moves from under the mouse pointer during hover animation, use the following and a current version of jQuery:
var result = $("#cont").height();
$('#ruch').on( 'mouseenter', function(){
$('#cont').animate({height:'300px'}, 500, function() {
alert( result );
});
});
$('#cont').on( 'mouseleave', function(){
if( $(this).height() != result ) {
$(this).animate({height:result}, 500);
}
});
Once the #cont expands the mouse is no longer over #ruch and any slight movement would fire mouseleave and the #cont collapses. To prevent that, attach the mouseleave event to #cont as above.
You could play around with some webkit transitions as well, which is pretty easy.
The problem with adding an event listener for when the mouse leaves the even and queuing up an animation is that you can end up with a queue of many animations if you move your mouse crazily over the div, while this method will only do one animation.
#cont {
border: 1px solid #000;
height: 200px;
overflow:hidden;
position:relative;
-webkit-transition: 0.5s;
}
#ruch {
position:absolute;
bottom:0px;
}
$(document).on('mouseover', '#cont', function() {
document.getElementById('cont').style.height = 300;
});
$(document).on('mouseleave', '#cont', function() {
document.getElementById('cont').style.height = 200;
});
