JQuery: Scrolling images - javascript

I would like to develop a scrolling function (on images) like on this site bethellery.com. At the moment, my code is kind of working, but I have a major problem: the size of the scrolling bar is nearly as big as my div size, so I can't scroll that much.
Here is the html:
<div id="container">
<div class="img-inner" id="img-1" style="display: block" >
<img class="img" src="src-1" alt="alt-1" />
</div>
<div class="img-inner" id="img-2" style="display: none" >
<img class="img" src="src-2" alt="alt-2" />
</div>
<div class="img-inner" id="img-3" style="display: none" >
<img class="img" src="src-3" alt="alt-3" />
</div>
<div class="img-inner" id="img-4" style="display: none" >
<img class="img" src="src-4" alt="alt-4" />
</div>
</div>
Here is the css:
html, body {
margin: 0px;
padding: 0px;
height: 100%;
}
#container {
height: 100%;
width: 50%;
overflow-y: auto;
}
.img-inner{
height: 100%;
width: 100%;
}
.img {
height: 100%;
width: 100%;
}
Here is the js:
var lastScrollTop = 0;
var x = 1;
$('#container').scroll(function(event){
var st = $(this).scrollTop();
if(st > lastScrollTop){
//downscroll code
document.getElementById('img-'+x).style.display = "none";
//if next image isn't the last image
if((x+1) !== 4){
x=x+1;
}
document.getElementById('img-'+x).style.display = "block";
}
else{
document.getElementById('img-'+x).style.display = "none";
if((x-1) !== 0){
x=x-1;
}
document.getElementById('img-'+x).style.display = "block";
}
lastScrollTop = st;
});
I don't really know what is happening but I think due to the fact the display styles of the div are none, the scroll doesn't detect the flow under the first image.
On the site above, scroll bar size is clearly adapting itself to the numbers of images the div contains.
Thank you very much and have a great day.

The problem here is that display: none; turns off the display of an element, so it has no effect on layout (MDN's words), meaning any calculations that involve it simply won't.
This is demonstrated by the following JSFiddle (your code) - now two images are set to display: block; and the scroll bar shows this.
Try using visibility: hidden; instead, as demonstrated here. Visibility leaves an elements space occupied while not showing it. It's effect is like opacity.

jQuery slider gives me scrollbars

guys. Trying to create my own gallery slider. But I have no idea how I can prevent the scrollbars. I know I have overflow: visible on both the wrapper and the images, but if I make it hiddenthen I won't see the images and they will get cropped off. What would be the best option here? Thanks.
<div id="wrapper" class="slider">

#wrapper {
text-align: left;
display: inline-block;
/*background-color: */;
white-space: nowrap;
position: relative;
left: -1150px;
overflow: visible;
}
#wrapper img {
margin-left: 20px;
white-space: nowrap;
overflow: visible;
}
var currentSlide = 2;
var slider = $(".slide");
setInterval(function() {
$(".slider").animate({position: "relative", left: "+=400px"}, 2000, function () {
currentSlide++;
/*$("#wrapper").css("overflow", "hidden");*/
if (currentSlide === (slider.length - 1)) {
currentSlide = 1;
$(".slider").css("left", "-1150px");
}
});
}, 5000);
My codepen: http://codepen.io/Limpuls/pen/pRbZKe
Simplest solution (and actually often (always?) used when you have this type of slider) is to add one more div as container, set 100% (desired) width, and add overflow hidden to it:
#container {
width:100%; //if 100%, you can even remove this line, 100% is default width
overflow:hidden;
}
Demo: http://codepen.io/anon/pen/YNWjOM
Your wrapper is pushed left too far, and can be even more, depending on number of images, and you have to hide overflow somehow.

CSS transition duration not applying on first instance of transition effect

I'm trying to create a series of sliding divs triggered on press of a button. The idea is that each div will have a thumbnail and some text tied to it. Upon clicking left/right button, the divs will move their position accordingly.
My code can be seen in the jsfiddle below. I'm encountering 3 problems:
1) The "transition: left 2s" rule isn't applying on the first transition effect, it does on the subsequent ones.
2) I'd like the repeat pressing of the corresponding buttons to apply the left property value again so that I can slide the divs repeatedly.
3) Instead of the "right" button re-positioning the "left" property back to 0, I'd like to shift it back in the opposite direction with the previous left property value.
Essentially I'm trying to recreate the slider found on this side.

Any help or input will be greatly appreciated.

left:0;
transition: left 2s;
}
Initially make left:0; for the div with id view https://jsfiddle.net/81tqeof4/6/
and for sliding effect get the current left position and update the position.check fiddle for an example
$("#left").on("click", function(){
var leftPosition = parseInt($("#view").position().left) - 256;
$("#view").css("left", -Math.abs(leftPosition));
});
transition works only on an existing property
So initially(in your CSS) you do not have a left property available in your #view. It is only later on a click that your JavaScript adds the left and your transition starts working.
So basically you need to set the left property to a value in your CSS, before your JavaScript takes effect and adds the left
#view {
position: relative;
width: 1423px;
left: 0; //initiate
transition: left 2s;
}

Iframe | Mobile back button on youtube iframe

I have got a video that appears in a light box from you tube, a custom one not a plugin.
On mobile when displayed portrait the video spans the full page width which looks nice and leaves some room at the top and bottom to click out.
The issue is when I go landscape the video fills the full screen and you cannot get back onto the page. My initial reaction was to hit the phones back button but I don't know a way of getting this to simply remove my lightbox. Is there a way in JS of getting a onclick off the phones back button?
The reason it goes full screen is because I am keeping the aspect ratio
var width: number = $('.youtube-video-lightbox').outerWidth();
var height: number = (width / 16) * 9;
$('.youtube-video-lightbox').height(height);
You can try using the following code:
You need to listen to navigation event and state.direction.
$(window).on("navigate", function (event, data) {
var direction = data.state.direction;
if (direction == 'back') {
// close the light box here
}
if (direction == 'forward') {
// do something else
}
});
More details in this link
Tested the above code in my mobile and it works fine. You might need to stop the program flow after closing the light box so that default navigation of the back button is stopped.

Hyperlink in JQuery Only Working in JSFiddle

I found something that can not only toggle on/off an image, but also make that image a link.
Problem: It only works in JSFiddle.
I put everything back into html (providing script) and made sure that everything was the same...but still, on my site it won't work. On JSFiddle, it does.
If anyone has a solution, I'd be most grateful.
The code I'm using for the site:
<center>
<p>
<div class="icon-container">
<a id="TOURBUTTON">
<img src="http://static.tumblr.com/6s0fefr/vFQn5uj2h/tournew.png" style="width: 188px; height: 188px;" />
</a>
</div>
</p>
</center>
<center>
<p>
<div class="display-container">
<img id="T5" style="display:none;" a href="http://music.britrodriguez.com" src="http://static.tumblr.com/6s0fefr/GXHnabnep/tahoeshow.png"/>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<script>
$(document).ready(function(){
$('#TOURBUTTON').on("click", function(){
$('#T5').toggle();
});
});
$('#T5').click(function(event){
var link = $(this);
var target = link.attr("target");
if ($.trim(target).length > 0){
window.open(link.attr("href"), target);
} else {
window.location = link.attr("href");
}
event.preventDefault();
});
</script>
<style type="text/css">
.icon-container{
display:inline-block;
margin-bottom: 0px;
margin-top: 10px;
}
</style>
The JSFiddle:

The site it's not working on:
http://www.britrodriguez.com/HITEST
Why do you open the url with JavaScript? Just try:
<a href="http://music.britrodriguez.com">
<img src="http://static.tumblr.com/6s0fefr/GXHnabnep/tahoeshow.png" />
</a>
These are just suggestions, but:
Make sure your HTML document is well formed and remove extraneous levels. The deeper the DOM tree goes, the "heavier" the page can get for the browser. Always strive towards a shallow DOM tree
The event handler when you click #T5 doesn't really need jQuery, I've used native JS, you can see it has a one to one drop-in.
Whenever you have a click event on an element, change the cursor for the user so they know it is clickable.
I have also user opacity to hide the #T5 instead of display. That way you can make it fade nicely

Side-Scrolling img div using .scrollWidth

I have simple html document that contains divs which hold a series of images:
<div id="container">
<div id="imagelist">
<a href="images/1.jpg"><img src="images/1b.jpg"/>
<a href="images/2.jpg"><img src="images/2b.jpg"/>
<a href="images/3.jpg"><img src="images/3b.jpg"/>
<a href="images/4.jpg"><img src="images/4b.jpg"/>
<a href="images/5.jpg"><img src="images/5b.jpg"/>
<a href="images/6.jpg"><img src="images/6b.jpg"/>
</div>
</div>
I would like to be able to scroll horizontall through the images when hovering over the left or right edge of the div (I have multiple #imagelists all stacked vertically)
I'm trying to use the .scrollWidth() function as such (this is in my script.js file):
var imglist = $('#imagelist');
$(imglist).mousemove(function(e) {
var percent = e.clientX / $(imglist).width();
$(imglist).scrollWidth($(imglist).width() * percent);
});
This doesn't work at all, of course! I've been trying to model this after some good examples I've seen, such as This. What should I alter to make my #imagelist scrollable?
Here's a way to do it using offset and relative positioning.
demo
The HTML looks similar to yours, with the exception that we create elements for the edges. The benifit is that we can style them with CSS, should you ever decide you want :hover styles (example in the demo).
<div class="imagecontainer">
<div class="imagelist">
<img src="http://placehold.it/400x300">
...
<img src="http://placehold.it/400x300">
</div>
<div class="edge right"></div>
<div class="edge left"></div>
</div>
The entire CSS is in the demo, this is just the essentials.
.imagecontainer {
width: 100%;
height: 400px;
overflow-x: hidden;
position: relative;
}
.imagelist {
/* Width allows up to 100 screenfuls, feel free to add a 0
Limiting can be done in the JavaScript */
width: 10000%;
height: 400px;
position: relative;
/* Give it a default left of negative to allow scrolling in either direction */
left: -500px; top: 0;
clear: right;
}
.imagelist img {
float: left;
}
.edge {
position: absolute; top: 0;
width: 50px; height: 100%;
}
.edge.left { left: 0; }
.edge.right { right: 0; }
The JavaScript is the fun part. We find the edges and watch for hover and leave events. Considering only one may be hovered at once (both practically and due to mouseenter), we simply have one timer pointer. This timer controls our animation, and is used to stop the animation (clearInterval) on mouseleave. 20 times per second we move the .imagelist 5 pixels in one direction. That's determined based on which edge we're hovering over.
Instead of using $('.imagelist') we use .parent().find('.imagelist') so that there may be any number of image lists on the page.
var timer = 0;
$('.edge').mouseenter(function(){
var $self = $(this);
var $imglist = $self.parent().find('.imagelist');
timer = setInterval(function(){
var amount, changed;
if ($self.hasClass("left"))
amount = -5;
else
amount = 5;
changed = $imglist.offset().left + amount;
$imglist.offset({left: changed});
}, 50)
}).mouseleave(function(){
clearInterval(timer);
});
It's a little rough, but you can polish it up to suit your needs.
