I'm trying to use jQuery for the first time. I have some images that are loaded via an ajax call (not jQuery related). The page is made the way that if you refresh the page, the images loaded, stay.
I found this code somewhere else:
$(document).ready(function(){
$(".svg_chart").click(function(){
var address = $(this).attr("src");
address = address.replace(\'height=80\', \'height=300\');
$("#popup").fadeIn("slow");
$("#lightbox").attr("src",address);
});
$("#lightbox").click(function(){
$("#popup").fadeOut("fast");
});
});
<div id="popup">
<div id="center">
<img id="lightbox" src="images/blank.jpg" >
</div>
</div>
</div>
The code works fine on images already loaded when the page is loaded, but not on images fetched on the fly with Ajax, although they get the same class added. I guess it is because the doc.ready function only knows about content, after the initial page has loaded.
What can I do to make jQuery know about new content being added?
Dropping jQuery for this. It's overkill and doesn't work!
<img id="svg_1" class="svg_chart" style="float: left" width="49%" ondblclick="expand_me(this.id)" alt="" />
<div id="popup">
</div>
<div id="center">
<img onclick="expand_me(true)" id="lightbox" src="images/blank.jpg" />
</div>
<script type="text/javascript"><!-- // --><![CDATA[
function expand_me(el)
{
if (el !== true)
{
link = document.getElementById(el).src;
link = link.replace(\'height=80\', \'height=300\');
document.getElementById(\'popup\').style.display = "block";
document.getElementById(\'center\').style.display = "block";
document.getElementById(\'lightbox\').src = link;
}
else
{
document.getElementById(\'popup\').style.display = "none";
document.getElementById(\'center\').style.display = "none";
}
}
// ]]></script>
The css part:
#popup
{
background:#000000;
height:100%;
width: 100%;
position:fixed;
top: 0;
left: 0;
display: none;
opacity: 0.9;
}
#center
{
height:100%;
width: 100%;
max-width: 1200px;
position:fixed;
top: 0;
margin: 6% auto;
display: none;
}
#lightbox
{
width: 100%;
cursor: pointer;
}

When my page loads there is an image that will appear. What I want to do is on scroll, fade out that image and fade in another image. While this animation is happening, I don't want the images to be scrolled up. It's only when the second image has faded in completely that I want to be able to scroll to the content that follows on the page.
I used this answer to come up with part of a solution.
html
<body>
<div id="container">
<div id="mainImg">
<img src="images/1.png" style="height: 100%">
</div>
<div id="brandStatement">
<img src="images/2.png" style="height: 100%">
</div>
</div>
<img src="images/map.png">
<script type="text/javascript" src="main.js"></script>
</body>
js
let locked = false,
mainImage = document.getElementById('mainImg'),
brandStatement = document.getElementById('brandStatement');
window.addEventListener('scroll', function() {
if (!locked) {
window.requestAnimationFrame(function() {
brandStatement.style.opacity = Math.min(window.scrollY / window.innerHeight, 1);
if (brandStatement.style.opacity === '1') {
// scroll to next content
}
locked = false;
});
}
locked = true;
});
css
#container {
height: 200vh;
width: 100%;
}
#mainImg {
text-align: center;
width: 100%;
height: 100%;
position: fixed;
}
#brandStatement {
text-align: center;
width: 100%;
height: 100%;
position: fixed;
opacity: 0;
}
I didn't see a possible solution to the problem by improving your code. This is a personal approach.
What I'm doing here, is changing the opacity of the element one inside the cover container as the user scrolls down the page, revealing the image below. After the opacity changes have been done, the script will change the filling container display style property from none to block. This element is just meant to fill the upper side of the cover container to prevent it from moving up when the position style property is changed from fixed to null.
And the reversed logic applies when scrolling back up.
const one = document.getElementById('one')
const cover = document.getElementById('cover')
const filling = document.getElementById('filling')
window.addEventListener('scroll', () => {
let scrollY = window.scrollY
let bottomHeight = window.innerHeight
if(scrollY / bottomHeight <= 1){
one.style.opacity = 1 - ( scrollY / bottomHeight )
cover.style.position = 'fixed'
filling.style.display = 'none'
}
else{
cover.style.position = null
filling.style.display = 'block'
}
})
*{padding:0;margin:0;border-size: border-box}

#cover > div{

I have a scrolling image gallery as follows. The CSS lays out the images in a row that scrolls horizontally. Underneath, I have a row of the same images, but as thumbnails. I want to be able to click on a thumbnail, and scroll the correct image into view.
HTML:
<div class="images_container">
<img id="image_1" src="/image1.jpg">
<img id="image_2" src="/image2.jpg">
<img id="image_3" src="/image3.jpg">
</div>
<div class="images_container thumbnails">
<img src="/image1.jpg" class="thumbnail">
<img src="/image2.jpg" class="thumbnail">
<img src="/image3.jpg" class="thumbnail">
</div>
CSS:
.images_container {
overflow-x: scroll;
overflow-y: hidden;
max-height: 50rem;
white-space: nowrap;
}
.images_container.thumbnails {
max-height: 10rem;
}
.images_container img {
vertical-align: top;
height: 50rem;
}
.images_container.thumbnails img {
height: 10rem;
}
This works up to a point, but jumping to the id of the image is problematic. If the larger image is even a few pixels into the visible viewport, it can't 'jump' to it, as it seems to be technically on the screen.
Is there a way I can use Javascript to 'scroll' the whole image into view when I click on it's corresponding thumbnail? I don't have access to jQuery on this project, but am happy to use JavaScript to make this work.
You can try this , no change in CSS, i add an id in html and call to scrollTo function :
<script>
function scrollTo(image_id){
var topLeft = document.getElementById(image_id).offsetTop;
document.getElementById('container').scrollLeft = topLeft;
}
</script>
<div id="container" class="images_container">
<img id="image_1" src="/image1.jpg" height="500px" width="500px">
<img id="image_2" src="/image2.jpg" height="500px" width="500px">
<img id="image_3" src="/image3.jpg" height="500px" width="500px">
</div>
<div class="images_container thumbnails">
<img src="/image1.jpg" class="thumbnail" onclick="scrollIntoView('image_1')">
<img src="/image2.jpg" class="thumbnail" onclick="scrollIntoView('image_2')">
<img src="/image3.jpg" class="thumbnail" onclick="scrollIntoView('image_3')">
</div>
To keep DOM cleaner I got this solution which requires only adding js
var elms = document.getElementsByClassName("thumbnail");
for (var i = 0; i < elms.length; i++) {
elms[i].onclick = function(event) {
event.preventDefault();
event.stopPropagation();
var id = this.parentNode.href.substr(this.parentNode.href.lastIndexOf('/') + 2);
var v = document.getElementById(id).getBoundingClientRect().left;
document.getElementsByClassName("images_container")[0].scrollLeft += v;
}
}
See on jsfiddle
Here's my attempt at a no (well, minimal) JS solution to a scrolling gallery. You could, in fact, remove the Javascript all together if you replaced the .active class with the :target pseudo-selector, allowing you to click your thumbnails to do the scrolling. It's just easier for me to do it this way through a fiddle
function removeClass(element, className) {
var classes = element.className.split(' ');
var key = classes.findIndex(function(name) {
return name == className
});
classes.splice(key, 1);
element.className = classes.join(' ');
}
function addClass(element, className) {
var classes = element.className.split(' ');
classes.push(className);
element.className = classes.join(' ');
}
setInterval(function() {
var current = document.querySelector('.images .image.active');
var next = current.nextElementSibling;
if (!next) {
next = document.querySelector('.images .image:first-child');
}
removeClass(current, 'active');
addClass(next, 'active');
}, 1500);
body {
margin: 0;
padding: 0;
width: 500px;
height: 500px;
}
.images {
width: 100%;
height: 100%;
position: relative;
overflow-x: hidden;
}
.image {
width: 100%;
height: 100%;
top: 0px;
position: absolute;
left: -100%;
float: left;
transition: 1s;
}
.image.active {
left: 0%;
}
.image.active ~ .image {
left: 100%;
}
.black {
background-color: black;
}
.red {
background-color: red;
}
.blue {
background-color: blue;
}
.yellow {
background-color: yellow;
}
<div class='images'>
<div class='image black active'></div>
<div class='image red'></div>
<div class='image blue'></div>
<div class='image yellow'></div>
</div>
Essentially the way it works is by making the div.images container a certain height and width, and therefore all images inside it can be positioned as you want. We initially set all .image to left: -100%, so that they're completely off screen to the left. We then set .image.active as left: 0 so that it's on screen. We then use the ~ selector to say that all siblings that come after the current (.image.current ~ .image) should be left: 100%, so completely to the right. Add in a transition, and you have a completely CSS scrolling gallery. The JS only acts as a way to change what the current active image is, and you can replace that with :target if you want.
I used div's, instead of img tags because it's easier to provide a POC with div's and background colors, but it's worked well with images in the past. Just put an <img> tag inside those <div class='image'></div> tags
I'm trying to show a fixed div using the show function of jquery. The show function works, but not when I try to add an effect with jquery ui. I have both jquery and jquery ui linked in an external file via a php include. When I use the inspector in chrome, I can see the blue box of the div I'm trying to show when I click the show button, yet the page remains unchanged.
This is my html:
<link rel="stylesheet" href="js/jquery-ui.min.css">
<script src='js/jquery-2.1.1.min.js'></script>
<script src="js/jquery-ui.min.js"></script>
<div class="twitterbar" id="baremily">
<a class="twitter-timeline" href="https://twitter.com/EmilyPalmaers" data-widget-id="number">Tweets by #EmilyPalmaers</a>
<script>!function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0],p=/^http:/.test(d.location)?'http':'https';if(!d.getElementById(id)){js=d.createElement(s);js.id=id;js.src=p+"://platform.twitter.com/widgets.js";fjs.parentNode.insertBefore(js,fjs);}}(document,"script","twitter-wjs");</script>
</div>
<div class="twitterbar" id="barcharlotte">
<a class="twitter-timeline" href="https://twitter.com/CPalmaers" data-widget-id="number">Tweets by #CPalmaers</a>
<script>!function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0],p=/^http:/.test(d.location)?'http':'https';if(!d.getElementById(id)){js=d.createElement(s);js.id=id;js.src=p+"://platform.twitter.com/widgets.js";fjs.parentNode.insertBefore(js,fjs);}}(document,"script","twitter-wjs");</script>
</div>
This is my jquery:
<script>
$(document).ready(function()
{
$("#twitteremily").click(function(e)
{
e.preventDefault();
if( $('#baremily').is(':visible') ) {
// it's visible, do something
$('#baremily').hide("blind");
}
else {
// it's not visible so do something else
if ($('#barcharlotte').is(':visible'))
$('#barcharlotte').hide("blind");
$('#baremily').show("blind");
}
});
$("#twittercharlotte").click(function(e)
{
e.preventDefault();
if( $('#barcharlotte').is(':visible') ) {
// it's visible, do something
$('#barcharlotte').hide("blind");
}
else {
// it's not visible so do something else
if ($('#baremily').is(':visible'))
$('#baremily').hide("blind");
$('#barcharlotte').show("blind");
}
});
}
);
</script>
and this is the css (note, the div I'm trying to show has a class and ID tag:
.twitterbar
{
position: fixed;
display: none;
top: 35%;
left: 50%;
margin-top: -10em;
margin-left: -10em;
z-index: 99999;
height: 20em;
width: 20em;
}
#media (min-width:961px) {
.twitterbar
{
top:50%;
margin-top: -16rem;
margin-left: -16rem;
height: 32rem;
width: 32rem;
}
}
I'm pretty much clueless at the moment, thanks in advance

Recheck your script references.
To make sure jQuery is ready, try:
if ( jQuery.isReady ) {
alert('jQuery is ready');
}
Edit:
Just a note: I also see you have your jquery css file inside your js folder.
Edit 2:

<img src="images/SAM_0047.JPG" href="www.xyz.com" >
<img src="images/SAM_0044.JPG" href="www.xyz.com" >
</div>
</body>
Try
<img src="images/SAM_0043.JPG" >
img tag has no href attribute.
wrap img tag with a tag n give href
Or with jQuery using your current code wrap a tag around img
fiddle Demo
$('div.fade img').wrap(function () {
return '';
});
embed the img tag into the anchor tag, and provide the href="" to the anchor tag. Your work is done.
href is not an img tag attribute so better to change the html to
<img src="" />
and if you dont want to change your html you can use code below to redirect to links on click on images
$(".fade img").bind('click',function(){
window.location = $(this).attr("href");
});

The solution to your problem is simply moving the import of the JavaScript file. It should be placed at the end after your two <img> tags.
<img src="http://placehold.it/250x150/cf5" data-full="http://placehold.it/860x590/cf5" alt="" />
<img src="http://placehold.it/250x150/fof" data-full="http://placehold.it/860x590/fof" alt="" />
<script type = "text/javascript" src ="trouble.js"></script>
It's standard practice to load your javascript files either last in the head or last in the body. Putting script tags inside of other html tags such as <div> as you have done is not normal but I've never seen it have ill effects like this before.
