I got an image gallery organized as an <ul>. all images are in <li> elements and when I move my mouse over one of those pictures, it should grow to give the user a visual feedback. thing is, when I just change the size of the image using animate(), the other pictures will be pushed to the side as the resized image uses more space.
therefore I went with cloning the image element, float it right over the original image and then calling animate. this comes with the problem that onMouseOut() is called as soon as the cloned images pops up. so I need a nested hover() function and this is where things got complicated.
I got two errors and I can't find out whats causing them. the first one is, that animate() won't let the cloned image grow beyond the right border of its original, the second is, that I get weird grow/shrink behavior, when moving my mouse quickly over the gallery.
html:
<ul id="gallery1" class="gallery_container">
<li class="frame">
<img src="pic1.jpg" class="picture" /></li><li class="frame">
<img src="pic2.jpg" class="picture" /></li><li class="frame">
<img src="pic3.jpg" class="picture" /></li>
</ul>
css:
.picture
{
height: 200px;
border: 0px;
margin: 0px;
padding: 0px;
}
.frame
{
display: inline-block;
position: relative;
margin: 0px;
margin-right:8px;
padding: 0px;
}
.frame a
{
padding: 0px;
margin: 0px;
}
.gallery_container
{
height: 200px;
width: 150%;
position: relative;
top: 4px;
padding: 0px;
margin: 0px;
}
and finally the code that is giving me those headaches:
$(document).ready(function()
{
var zooming = false;
var zoom = 4;
var speed_zoom = 100;
$('.gallery_container li a').hover(function(element)
{
// disable zooming to prevent unwanted behavior
if(zooming) return;
zooming = true;
$(this).after( $(this).clone(false) );
$(this).next().attr('id', 'focus_frame');
},
function(element) // when the new element pops up, onmouseout is triggered, since the focus_frame is in front of the image
{
$(this).next().hover(function(element)
{
// we need to re-position the element in the dom-tree, since it needs to grow out of a container with overflow: hidden
$('#focus_frame img').animate({'left' : zoom * -1, 'top' : zoom * -1, 'height' : 200+(zoom*2), 'width' : $('#focus_frame img').outerWidth() + (zoom*2)}, speed_zoom);
},
function(element)
{
$(this).remove();
zooming = false;
});
});
});
var $doc=$(document.body)
$doc.on({
"mouseenter" : function (e) {
$doc.find("> .gallery_clone").remove();
var $i=$(this).parent();
$i.pos = $i.offset();
$i.clone()
.addClass("gallery_clone "+$i.parent().parent().attr("class"))
.css({
top:(Math.round($i.pos.top)-3)+"px"
,left:(Math.round($i.pos.left)-3)+"px"
,width:$i.width()
}).appendTo($doc);
}
},
" ul > li > img"
).on ({
"mouseleave" : function (e) {
$(this).remove();
},"> .gallery_clone");
in css .gallery_clone is position:absolute
then i animate .gallery_clone:hover through css but you can do it in the jquery as well i guess, adding a mouseenter event on .gallery_clone
edit : i've literally copy/pasted from my script so you'll have to adapt this code to your html
nb: give css anim a go, it's worth it even if older ie will not animate; (i also made lightbox effect almost pure css for that same gallery - will publish later, not ready for plugin release just now sorry)
nb2: that part "+$i.parent().parent().attr("class") is because in the cms they can chose gallery background color so adding that class forward the background color & other gallery style to the clone (ie you should not need it)

I have a portfolio grid of images and when a user hovers or taps on a mobile a transparent overlay with some text and a button appears
I am using the on click function
It works fine on my touch screen laptop but not on my iOS phone or tablet
The overlay appears on first tap, but when I tap again it does not disappear unless I tap another grid image.
I would like it to disappear on 2nd tap
I have tried various ways of making this work, and the closest I have got it for it to disappear when another grid image is tapped
Here is my code:
HTML
<div class="col-xs-12 col-sm-7"><div class="image-wrap">
<div onclick="on()">
<img src="assets/images/pic.jpg">
<div class="overlay blue">
<h3>Portfolio item 1</h3>
<hr>
<p><strong>Coming Soon</strong><br> some overlay text here</p>
<br>
View Website
</div>
</div>
</div>
</div>
JS
function on() {
document.getElementById("overlay").style.display = "block";
}
function off() {
document.getElementById("overlay").style.display = "none";
}
CSS
.image-wrap {
display: inline-block;
position: relative;
}
.overlay {
position: absolute;
top:0;
left: 0;
width: 100%;
height: 100%;
color:white;
opacity: 0;
transition:opacity .5s ease-out;
text-align: center;
hr {
border: 1px solid #fff;
width: 10%;
}
}
.image-wrap:hover .overlay {
opacity: 1;
}
.red {
background: rgba(102,67,154,0.7);
}
.blue {
background: rgba(23,56,179,0.7);
}
.purple1 {
background: rgba(140,23,179,0.7);
}
.purple2 {
background: rgba(71,13,142,0.7);
}
}
I initially tried this with just CSS which gave me the desired result on all devices apart from iOS!
So I have decided to use the on click function to be more sure it works on all devices. I added the on click function to my existing code which I wrote to be used with CSS, but as I am rather new to JS I am wondering if I have it in the wrong place (the on-click)? I have tried lots of variations but this is the best I can get it to work
Any ideas of suggestions on how I can make the overlay disappear on the 2nd click would be great!
js fiddle
https://jsfiddle.net/49h450g9/14/
Please note: This works fine on touch-screen laptops, just not mobiles!
Thanks!
Your functions on and off on jsfiddle example are not working at all. What happening is your hover effect on normal screen which as the behavior of mobile work like focus on mobile device.
Moreover, from your description here I believe that you have more than one portfolio on your project. So you have several element with the id overlay and multiple use of same id is not validate for html and also will cause JavaScript error.
To let your project work properly follow my list below:
Make sure you have jQuery added on your project (generally before </body>)
Now let us thinks of these portfolio item below
<div class="portfolio">
<img src="images/portfolio-1.jpg" alt="...">
<div class="overlay">Link</div>
</div>
<div class="portfolio">
<img src="images/portfolio-2.jpg" alt="...">
<div class="overlay">Link</div>
</div>
<div class="portfolio">
<img src="images/portfolio-3.jpg" alt="...">
<div class="overlay">Link</div>
</div>
Then give the normal hover css styles inside media query like this. So that it never effect your js styles (I decide medias less than 992px as mobile device):
.portfolio{
background-color: #f1f1f1;
position: relative;
}
.portfolio .overlay{
background-color: rgba(0, 0, 0, 0.7);
display: block;
position: absolute;
top: 0;
left: 0;
opacity: 0;
transition: all 0.3s ease;
width: 100%;
height: 100%;
}
#media all and (min-width:992px){
.portfolio:hover .overlay{
opacity: 1;
}
}
Now with jQuery you can use event while user click any of the .portfolio item and toggle a class on it by which we will add further css to it:
$(document).ready(function(){
'use strict';
$(.portfolio).on('click', function(){
$(this).siblings('.portfolio').removeClass('hovered');
$(this).toggleClass('hovered');
});
});
Now it will add hovered class on 1st click and remove the hovered class on 2nd click. Also it will remove .hovered from other portfolio items. Now add the same css to it as the hover effect:
.portfolio.hovered .overlay{
opacity: 1;
}
Try this:
$("*").on("click, touchend", function(e) { $(this).focus(); });
or to achieve the opposite;
$("*").on("click touchend", function(e) { $(this).hover(); });
However the hover event doesn't work well on ios or other mobiles.
Another suggestion is to try replace any css using
:hover with :active.
I am trying to achieve below image type of slider using Superslides and Bxslider.
Slider Explanation:
Black boxes are points/stops.
Blue box is car.
Whenever car crosses the half way stop,I need to change the red slider to next one.
User can use mouse scroll or arrow keys to move car forward or backward & on mobile using swipe forward or backward.
What I have done using Superslides and Bxslider
Using callback functions of bxslider to animate the car, but stuck.
Help: I need ideas how to achieve such result.What kind of slider I can use to acheieve something like this.
Reference link but with jQuery
(function($) {
var elem = $.jInvertScroll(['.scroll'], // an array containing the selector(s) for the elements you want to animate
{
height: 6000, // optional: define the height the user can scroll, otherwise the overall length will be taken as scrollable height
onScroll: function(percent) { //optional: callback function that will be called when the user scrolls down, useful for animating other things on the page
console.log(percent);
}
});
$(window).resize(function() {
if ($(window).width() <= 768) {
elem.destroy();
}
else {
elem.reinitialize();
}
});
}(jQuery));

Hi there I need to an interactive element using a large image. This image sized 1000x1000 pixel with simple imagery will contain several questions with yes or no. What I want to do is place this image within a small div (say 500x300) with hidden overflow and add hotspots on the image for the yes/no option. What I want is when the user clicks yes, then the hotspot link pans to specific x/y coordinates of the same large image. Viewer will only see within the 500x300 window. So on and so forth. Is this possible? It seems so simple yet only option I can find is the pan by mouse option or iframe option with complicated divs and anchors. I'm not an expert in java/jquery but would love to find a script that is adaptable. Please help!
This sounded fun so I made a custom solution real quick. Demo here: jsBin
It's heavily reliant on the proper CSS, so check that in the bin, but here's the JS part:
var choice = document.querySelectorAll('.choice'),
image = document.getElementById('image')
for ( var i=0; i<choice.length; i++) {
choice[i].addEventListener('click', function (event) {
var x = this.dataset['x'],
y = this.dataset['y'];
image.style.top = '-'+y+'px';
image.style.left = '-'+x+'px';
})
}
Use css transitions for animation. Set up the positions you want the buttons to move the image around to in the image using a series of javascript objects. Then, set up your anchors, text, etc using absolute positioning on top of the image inside of a div container. Finally, add a click action in jQuery to assign your different positions to the top and left css of that container.
The end result, then, will be that you click an anchor, the left and top positions are assigned to the container via css in jQuery, and the transitions will slide the image around with the anchors.
I set up a fiddle here.
Here's the html from the fiddle:
<div id="window">
<div id="container">
<img src="http://upload.wikimedia.org/wikipedia/en/1/1f/Kill_The_Lights_1000x1000.jpg" id="image">
<ul>
<li><a id="city" href="#">City</a></li>
<li><a id="bottom" href="#">Bottom</a></li>
</ul>
</div>
</div>
And the CSS:
#window {
width:500px;
height:300px;
overflow:hidden;
position:relative;
}
#window a {
position: absolute;
z-index: 2;
display: block;
padding: 10px;
background: rgba(255,255,255,.5);
}
#city {
top: 20px;
left: 20px;
}
#bottom {
top: 220px;
left: 220px;
}
#container {
-webkit-transition:left 2s, top 2s, -webkit-transform 2s;
transition:left 2s, top 2s, transform 2s;
position: absolute;
z-index: 1;
top: 0px;
left: 0px;
}
Here's some javascript to give an example of setting up the positions as objects.
var city = {
top: -200,
left: -200
};
var bottom = {
top: -700,
left: -100
}
$('a').click(function() {
var t = this.id;
var c = $('#container');
if (typeof eval(t) !== 'undefined') {
c.css({
'top': eval(t).top,
'left': eval(t).left
});
}
});
I've just made a Fiddle with a demo image from where you could proceed.
HTML:
<div class="imgHolder">
<div class="hotspot one">Click</div>
<img src="image.jpg" />
</div>
CSS:
.imgHolder {
overflow:hidden;
width:300px;
height:300px;
position:relative;
}
.hotspot.one {
position:absolute;
top:10px;
padding:2px;
background-color:#fff;
left:10px;
}
.hotspot:hover {
cursor:pointer;
}
img {
position:relative;
z-index:-1;
}
jQuery:
$(".hotspot").on("click", function () {
$("img").animate({
"right": "+=100px"
});
});
For reference: http://api.jquery.com/animate/
You could e.g. fade hotspots in and out on specific positions and use animate() to move to the next hotspot.
I'm trying to replicate the effect on this website in the portfolio section where it slides a panel in the full size of the viewport and then slides it out when you click close.
Example here: http://alwayscreative.net/#portfolio
Here's my current markup:
<section class="panel" id="portfolio">
<section class="content">
<h1>What are you <strong>interested</strong> in?</h1>
<a class="btn-portfolio" id="btn-commercial" href="#">Commercial</a>
<a class="btn-portfolio" id="btn-residential" href="#">Residential</a>
</section>
</section>
The .panel section is 100% height and width of the viewport and I'd like 2 different panels to be able to slide in — one for #btn-commercial and one for #btn-residential.
Any ideas how to make this happen?
If it helps any, here's my site so far: http://www.freshbrand.ca/testlink/top40/#portfolio
Here's how you would do it with JQuery but clearly you can do it in normal javascript if you prefer. Set up the panels with position absolute in your css:
.panel {
position: absolute;
top: 0;
height: 100%;
border-width: 0;
margin: 0;
}
.panel inactive{
display: none;
}
.panel active {
display: block;
left: 0;
width: 100%;
height: 100%;
}
in your javascript (after the dom has loaded) get the screen dimensions and set the positions of the inactive elements to just off the right hand edge of the screen:
$('.panel').css('width', screen.innerWidth);
var setup = function() {
$('.portfolio-panel.inactive').css('left', window.innerWidth);
$('.portfolio-panel.active').css('left', 0);
}
setup();
When you wish to slide a panel in from the right, pass its id to the following function:
var slideIn = function(panelId) {
$('#' + panelId).animate({
left: 0
}, 400, function () { // animates the #left property from the screen width down to zero (i.e. slide it in from the right hand edge of the screen)
// tidy up
$('.portfolio-panel.active').removeClass('active').addClass('inactive');
$('#'+panelId).removeClass('inactive').addClass('active');
setup();
});
};
EDIT: The event handler would look something like this:
$('.btn-portfolio').click(function() {
slideIn($(this).attr('id').substr(4)); // extract the panel name from the id and pass it into slideIn
});
The only remaining issue is to eliminate the horizontal scroll bar you will probably see during the animation. Just add overflow-x: hidden; to the element to which the scroll bar belongs (probably body, but it depends on how you've structured and styled the rest of your site)
This is basically a single page website, a lot of jQuery plugins are available for the same.
I personally prefer

Check out it's demo and download the code from github's link

Hope this helps
Hi I am trying out simple rollover images for a site I am currently working on. When I test the effect in firefox, the mouseover effect moves other elements on the webpage. any suggestions on how to fix this?
<head>
<script type="text/javascript">
if (document.images) {
img1 = new Image();
img1.src = "training2.png";
} </script></head>
<body>
<script type="text/javascript">
function rollover(name, filename)
{
var fullpath = '' + filename;
document.images[name].src = fullpath; }
</script>
<div id="trainingbutton"><a href="#" onmouseover="rollover('button1','training2.png');" onmouseout="rollover('button1','training.png')">
<img src="training.png" name="button1" border="0" alt="training" /></a></div></body>
As the previous person answered; sprites are the way to go. It takes care of having to preload the "hover" image; and it's pure CSS.
Example (an image link rollover):
HTML:
Join Newsletter
Put both your non-hover and hover state images on a single canvas. If each "image" is 20px tall, the two stacked would be 40px. So to make the bottom image show, you simply shift the background up 20px (hence -20px on the hover state below)
CSS:
.mysprite {
display: block;
width: 100px;
height: 20px;
background: url('mysprite.png') no-repeat;
background-position: 0 0; /* technically not neccesary, but illustrates the example */
text-indent: -9999px; /* eliminates the link text so only the background image shows */
font: 0px; /* eliminates IE displaying the text despite text-indent */
}
.mysprite:hover {
background-position: 0 -20px;
}
Essentially, your creating a "mask" from which you shift the background image underneath to reveal what you want it to.
I would not use javascript for roll over images, simply create a sprite containing both the normal state and the hover state, and then by using the hover attribute of css you can shift the background position.
Something like this:
<a class="rollover">Link</a>
And then the style:
a.rollover
{
background-image:url('/images/background.png');
background-position:top left;
}
a.rollover:hover
{
background-position:bottom left;
}
This method also does not suffer from having to download the image when you rollover as it is downloaded as part of the initial request
