javascript for a simple lightbox seems not to be functioning - javascript

I'm new to programming unfortunately and so to help me I have been following some simple tutorials on youtube (in addition to following Treehouse lessons). The one I have been struggling with and can't seem to find a solution to is building a simple lightbox, well getting the click event to bring up the lightbox. I have checked all lines, syntax, whether I've omitted a ; or {}, thought maybe I had the javascript src incorrect, tried downloading, creating a js folder and linking to that, referencing google hosted javascript, checked firebug, tried different browsers, checked that the CSS is correct (which it seems to be as when setting the display to block it appears OK), thought maybe there is updated syntax rules (tried jQuery instead of $ but just can't see where I'm making an error. Probably I have omitted something really simple, so please forgive me in advance. The youtube link I'm following is: https://www.youtube.com/watch?v=k-uonF7Gdgw Have also checked the comments to the video to see if anyone else is having same problem, some are, but mostly everyone else seems ok, and no solutions posted for those not getting it to work!
Please see below code:
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<script type="text/javascript">
jQuery(document).ready(function(){
jQuery('.lightbox').click(function(){
jQuery('.backdrop, .box').animate({'opacity':'.50'}, 300, 'linear'); //fades in the backdrop and the lightbox - speed of 300, and displayed in a linear fashion. Only want the backdrop displayed with 50% opacity, and the box at 100% (see below line)
jQuery('.box').animate({'opacity':'1.00'}, 300, 'linear');
jQuery('.backdrop, .box').css('dispaly', 'block'); //sets the appearance of the box
});
});
</script>
Many thanks in advance, and thanks for great resource!

Lightbox is a JavaScript technique used to display images and other web content using modal dialogs where the image is shown up center filling most of the screen, and the rest of the window is dimmed out. Lightbox was originally the name of a specific JavaScript plugin. However, common usage of the term has evolved to encompass Lightbox-style JavaScript plugins and effects in general.
First we take some images (when we click on the images the LightBox will be shown). We will place this image in a
HTML code:
<section id="examples" class="examples-section">
<div class="container">
<h3 style="clear: both;">Four image set</h3>
<div class="image-row">
<div class="image-set">
<a class="example-image-link" href="img/demopage/image-3.jpg" data-lightbox="example-set" data-title="Click the right half of the image to move forward."><img class="example-image" src="img/demopage/thumb-3.jpg" alt=""/></a>
<a class="example-image-link" href="img/demopage/image-4.jpg" data-lightbox="example-set" data-title="Or press the right arrow on your keyboard."><img class="example-image" src="img/demopage/thumb-4.jpg" alt="" /></a>
<a class="example-image-link" href="img/demopage/image-5.jpg" data-lightbox="example-set" data-title="The next image in the set is preloaded as you're viewing."><img class="example-image" src="img/demopage/thumb-5.jpg" alt="" /></a>
<a class="example-image-link" href="img/demopage/image-6.jpg" data-lightbox="example-set" data-title="Click anywhere outside the image or the X to the right to close."><img class="example-image" src="img/demopage/thumb-6.jpg" alt="" /></a>
</div>
</div>
</div>
</section>
Now add css code files for screen and lightbox. Also download lightbox.js and jquery library java-script files.

Lightbox2 next arrow disappears after the first image of the group

I have 3 pics that I want to link them in my photo gallery. So when I click one of the image, it should have the next and previous arrow that allow the user to go to another image. My codes with lightbox2 is as below.
<a href="my/path/images/image1.jpg" data-lightbox="roadtrip" data-title="My caption">
<img src="my/path/thumbnails/thumb1.jpg" alt="Surfing"/>
</a>
<a href="my/path/images/image2.jpg" data-lightbox="roadtrip" data-title="My caption">
<img src="my/path/thumbnails/thumb2.jpg" alt="Lifeguard Stand"/>
</a>
<a href="my/path/images/image3.jpg" data-lightbox="roadtrip" data-title="My caption">
<img src="my/path/thumbnails/thumb3.jpg" alt="Hot Air Balloons"/>
</a>
So now when I run the code, in the first image there will be an next arrow that links to the second image. However, when the user is in the second image, there is only previous arrow but no next arrow. But I want both arrows to appear.
If anyone knows how to solve the issue, please let me know. Appreciated!!
Ok so I found the answer by myself and below is the answer for many people who may have encountered the same problems.
Just change the width of .lb-nav a.lb-prev in the lightbox.css and it should work. I change it from 64% to 50% and then the next arrow appears.
I don't have time digging into what's the essential cause is, but this solution does work. If anyone knows what exactly happens there, please feel free to leave a comment or answer. Appreciated!

HTML pop up on click within WordPress

In the WordPress theme I am using there is an area for HTML banner code. At the moment it contains the following:
<a href="http://bathcitysound.com/streaming/player.html">
<img src="my-image-code-goes-here" /></a>
All is well and good, and it functions as it should and when clicked it goes to the specific page. However, what I actually want to happen is when the image is clicked, it opens a pop up window of 300 pixels wide and 600 pixels height with this as the address:
http://bathcitysound.com/streaming/player.html
What should I add to the existing code to make that work?
This should work:
<a href="javascript:window.open('http://bathcitysound.com/streaming/player.html','yourWindowTitle','width=300,height=600')">
<img src="my-image-code-goes-here" />
</a>
You can try in your browser, by going to this URL:
javascript:window.open('http://bathcitysound.com/streaming/player.html','yourWindowTitle','width=300,height=600')

javascript examples display content boxes

I am trying to locate javascript code that, when I rollover an image, will make a box appear below the image and expand down (much like how a movie screen in a theater would roll from the ceiling to the floor). In that box, content would also appear, that I have previously added, that describes the image above. Already existing underneath the image I have a div with content in it...I would also like this div to be pushed down as the box described above expands down.
Any suggestions?
Thank you very much in advance!
C*
Forgot the code that I am using...so what is happening here is that I have a picture, and below it, a small box, that when I rollover that small box it changes color. So, I want to add, when I scroll over that small box, not only does it still change color, but the new vertical expanding box appears below it. I have javascript in a *.js file that handles the already existing rollover effect but it's quite long and I wasn't sure if I should add that (it was create by Dreamweaver when I created a rollover image).
<div class="images">
<figure class="images">
<img src="../images/Flower2.jpg" width="300" height="199" alt="Life">
</figure>
<figcaption class="content"><a class="typeB" href="#" onmouseout="MM_swapImgRestore()" onmouseover="MM_swapImage('Image3','','../graphics/life2.jpg',4)"><img src="../graphics/life1.jpg" width="300" height="25" id="Image3" /></a>
</figcaption>
</div>
You don't give much information in your question about your current setup, but assuming that you have your HTML set out something like this:
<div>
<img id="tux" src="http://upload.wikimedia.org/wikipedia/commons/1/1c/Crystal_128_penguin.png" />
<div id="tux_desc" class="imgDesc" style="display: none">
<p>A cute penguin!</p>
</div>
</div>
<div>
<p>This text is part of the normal document flow</p>
</div>
Then you can use the following JavaScript (which makes use of jQuery):
$('#tux').hover(
function() {
$('#tux_desc').slideDown();
},
function() {
$('#tux_desc').slideUp();
});
You can see it working here: http://jsfiddle.net/wbAxm/1
something like this ought to to do it as long as the div to expand is directly after the image in the mark-up:
$(".class_for_images").on("mouseenter mouseleave", function() {
var content = $(this).next();
if (content.is(":visible")) {
content.slideUp();
} else {
content.slideDown();
}
});
If you want more than this, or it doesn't work, you'll need to post some code so that we can provide more detailed answers...

how to prevent fancybox from deleting the clicked thumbnail

Fist time using fancybox and it's not going so well.. starting to wish I didn't bother with it.
I have some thumbnails in a row, fine, then when I click one it opens the THUMBNAIL instead of the link whats worse it DELETES the thumbnail from the DOM. I've dug around in the fancybox src for the issue but there's a lot of it and I'll probably end up killing functionality so I thought I'd post here.
heres the code:
The raw HTML comes from CMS looking like:
<img src="http://blah..blah..from..flickr..001_s.jpg" alt="my image one" class="flickr-square" title="test image" longdesc="" data-url="http://blah..blah..flickr..detail..page" data-orig="http://blah..blah..flickr..big..001_b.jpg">
<img src="http://blah..blah..from..flickr..002_s.jpg" alt="my image one" class="flickr-square" title="test image" longdesc="" data-url="http://blah..blah..flickr..detail..page" data-orig="http://blah..blah..flickr..big..002_b.jpg">
I then run some stuff in backbone view render, the important bit is this:
var imgs = this.$el.find("img"); //:a jquery group of the img elements above
this.content = this.$el.find("span.postcontent");
//empty current
this.content.empty();
//make replacement
for(i= 0;i<imgs.length;i++)
{
var curImg = $(imgs[i]);
var curLink = $("<a/>");
curLink.attr("href",curImg.attr('data-orig'))
curLink.append(curImg);
curLink.on("click",function(e){
e.preventDefault();
$.fancybox.open(imgs)
});
this.content.append(curLink)
}
I now have rendered html like this:
<a href="http://blah..blah..flickr..big..001_b.jpg">
<img src="http://blah..blah..from..flickr..001_s.jpg" alt="my image one" class="flickr-square" title="test image" longdesc="" data-url="http://blah..blah..flickr..detail..page" data-orig="http://blah..blah..flickr..big..001_b.jpg">
</a>
<a href="http://blah..blah..flickr..big..002_b.jpg">
<img src="http://blah..blah..from..flickr..002_s.jpg" alt="my image one" class="flickr-square" title="test image" longdesc="" data-url="http://blah..blah..flickr..detail..page" data-orig="http://blah..blah..flickr..big..002_b.jpg">
</a>
So far so good... now, when I click the link/thumb it does the fancybox thinggy but shows the THUMBNAIL not the linked image, tiny in the middle in it's lightboxy thing and whats really annoying is that the clicked thumbnail in the page itself has now been completely removed from the dom ie.:
<a href="http://blah..blah..flickr..big..001_b.jpg">
///THIS IS MISSING COMPLETELY..... ggggggrrrrr
</a>
<a href="http://blah..blah..flickr..big..002_b.jpg">
<img src="http://blah..blah..from..flickr..002_s.jpg" alt="my image one" class="flickr-square" title="test image" longdesc="" data-url="http://blah..blah..flickr..detail..page" data-orig="http://blah..blah..flickr..big..002_b.jpg">
</a>
I've never seen Fancybox used like that. Normally, you don't need to trigger $.fancybox.open like that. You can just bind fancybox() to the <a> tags.
HTML:
<a href="big-image.jpg" class="fancybox">
<img src="thumbnail.jpg">
</a>
JavaScript:
$('.fancybox').fancybox();
Try just using that function after you've got the DOM to look like that.
[edit]
I couldn't get your DOM manipulation to quite work, but I tested with this fiddle, and it seems to be working: http://jsfiddle.net/haRnQ/4/
NOTE: I didn't import the styles or images for the demo, so it will be unstyled, but it still works.
I'm answering and voting up the previous two because they both helped but were not the definitive answer. The documentation was not clear that if you use only the "group" as a jquery array you must also specify options therefore the correnct answer is to do this (passing two arguments):
$.fancybox.open(imgs,
{
href:this.href,
title:curImg.attr("title")
}
);
Try changing this
$.fancybox.open(imgs)
by this
$.fancybox({
href: this.href
});
because imgs is the collection of your thumbnails (all <img> elements), which are moved to fancybox on click but not moved back after close.
In any case I would recommend you to add a class to <a> otherwise any other anchor you may have in your page would try to open fancybox.
I believe Fancybox prefers wrapping your images in an anchor. This is important to note as Fancybox removes the anchor when activating a slide show to prevent clicking on the anchor when the modal is active.
Calling FB from the thumb behaves like you have experienced by deleting the thumb and not recovering it after the modal is closed.
This is my typical FB setup (not a thumb gallery):
<img src="image1.jpg" alt="" />
<div style="display: none">
...
</div>

FancyBox returning "The requested content cannot be loaded. Please try again later." with link

I'm using Fancybox to display inline content (a div with an image linked to a new page). The div and image display fine in the modal, but when the image is clicked to go to the new page, I get "The requested content cannot be loaded. Please try again later." error.
The FancyBox javascript is as follows:
<script type="text/javascript">
$(document).ready(function() {
$(".fancybox").fancybox().hover(function() {
$(this).click();
});
$("#fancybox-outer").fancybox().mouseleave( function() {
$("#fancybox-overlay").click();
});
});
</script>
And applies to the following clip of HTML:
<li class="fancybox-outer">
<a id="inline" href="#hover-image_0" class="fancybox">
<img src="http://website.com/file/id:63" style="margin-top: 32px" />
</a>
<p>1G2A</p>
<div style="display: none;"><div id="hover-image_0"><img src="http://website.com/file/id:64/ext:.png" class="img" /></div></div>
</li>
<li class="fancybox-outer">
<a id="inline" href="#hover-image_1" class="fancybox">
<img src="http://website.com/file/id:60" style="margin-top: 32px" />
</a>
<p>17</p>
<div style="display: none;"><div id="hover-image_1"><img src="http://website.com/file/id:61/ext:.png" class="img" /></div></div>
</li>
Does anyone see what might be causing the issue or what I need to correct?
Thanks!
Update: 1/19/2012 - I performed the same test on my server as the first answer (http://estorkdelivery.com/example/example.html) and found that I got the same response back. So it seems it's something with my server.
I still need help with this issue. Anyone have any ideas?
Thanks!
Update: 1/28/2012 - I've been working to find a solution for this problem, but I've run out of time and have gone with a completely different solution. I'm keeping this problem open in case anyone else runs across the same error or ultimately finds a solution. Thanks!
Your approach has many issues:
First bear un mind that fancybox gets its content from the href attribute of any selector bound to it so the link
<a class="fancybox" href="{target}" ...
should be bound to fancybox via the following script in order to work
$('.fancybox').fancybox();
Pretty obvious but in your approach, the link inside the opened fancybox (which targets to yahoo for instance) is not bound to fancybox itself; it will try to fire Fancybox for sure again but with no indication of what the content should be this time, hence the error "The requested content cannot be loaded. Please try again later." in other words, the link (inside the inline content) <a href="http://yahoo.com" ... is not bound to fancybox.
The only way that links inside fancybox can work and load content dynamically (without being bound to fancybox) is when the current content is an external html document and fancybox type was set to iframe (not your case)
Second, you opened an image so fancybox set the type to image by default, but then you are pretending to load a different type of content on the same box (yahoo for instance), which would require to set type to iframe and other options like width and height.
Third, since you are using inline content, please be aware of an existing bug in v1.3.x and its workaround to avoid further issues, you can learn more here
Last, I am not just lecturing here, it's more like the explanation of what is going on with your issue .... but the good news is that you just need to add some more lines of code to make it work the way you want:
1: you need to create a fancybox script for each type of content you want to open the second time (additionally to your existing one), so in your example you want to click the image inside fancybox and that should open yahoo ... then create this script
$('.fancyframe').fancybox({
'type':'iframe',
'width': 600, //or whatever you want
'height': 300
});
2: within your hidden inline content set that class to the link, so this code:
<div style="display: none;">
<div id="hover-image_0">
<img src="1_b.jpg" class="img" />
</div>
</div>
now should look like
<div style="display: none;">
<div id="hover-image_0">
<a class="fancyframe" href="http://www.yahoo.com"><img src="1_b.jpg" class="img" /></a>
</div>
</div>
Do the same for each hidden inline content. If you want to open another type of content in fancybox, just create a script accordingly. The rest of your code is OK (doesn't bother me to fire fancybox on hover)
SIDE NOTES: sites like google, yahoo, jquery and some others won't open in fancybox. Also make sure you have the proper DOCTYPE for fancybox to work properly (your sample page doesn't have any). See Unable to load google in iframe in fancybox for explanation.
I think I've figured out what's causing this issue, at least for me.
The problem seems to occur when you've got a class on one of your elements that is the same as the popup class.
For instance:
<a class="popup" href="#">Open the popup</a>
And you have something in your popup with the same class name, for instance:
<div class="popup">some text</div>
You'll get the error. Try changing the div class to something like popup-window - that should fix your error
In your example page, it works for me if I don't click. When you click, what page are you supposed to be taken to? Do you want it to just go to the next image?
In my personal preference, I don't care for the activation on hover. It gets really confusing, especially when most people go to instinctually click on an image. But in your case it opens on hover, then they click instinctually, then you get the error.
Do you get this same error when you're just using the functionality as it normally applies?
If you want, try to give each image a gallery name instance like so: rel="gallery" and see what happens. You should get the next/prev arrows showing up and working like you would expect.
But honestly, I would get rid of the hover functionality altogether. Or at least get rid of the mouseout() That's probably the most bothersome part.
Just use this to call the fancybox actions:
$("a[rel=gallery]").fancybox();
That way you can get rid of all of those classes that are probably causing the issues.
I hope that helps.
I just ran into this issue as well.
As it turns out, the href url is EXTRA case sensitive. (if that is possible)
Regardless double, triple check your href urls to insure that you have the case exactly correct.
my solution was:
<script type="text/javascript">
jQuery(document).ready(function() {
$(".fancybox").click(function() {
$.fancybox({
'padding' : 0,
'autoScale' : false,
'transitionIn' : 'none',
'titleShow' : false,
'showCloseButton': true,
'titlePosition' : 'inside',
'transitionOut' : 'none',
'title' : '',
'width' : 640,
'height' : 385,
'href' : this.href,
'type' : 'iframe',
'helpers' : {
'overlay' : {'closeClick': false}
}
});
return false;
});
});
</script>
If some of the images are showing and others are not, even though the markup is identical, then check this:
Try to lowercase all the letters in the filename and in the html. Fancybox seems to be quite case sensitive.
Check if the image has all the permissions allowed. I noticed my pictures didn't work properly on mobile because on my computer, everybody's permission was set to "no permission". I changed this to "read only" and it worked like a charm!
I just re-created your test on my local machine and it works fine for me (I ran this from the demo folder of the FancyBox install) :
<html>
<head>
<title>jQuery Fancybox Test</title>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.js" type="text/javascript"></script>
<!-- Add fancyBox main JS and CSS files -->
<script type="text/javascript" src="../source/jquery.fancybox.js"></script>
<link rel="stylesheet" type="text/css" href="../source/jquery.fancybox.css" media="screen" />
</head>
<body>
<script type="text/javascript">
$(document).ready(function () {
$(".fancybox").fancybox().hover(function () {
$(this).click();
});
$("#fancybox-outer").fancybox().mouseleave(function () {
$("#fancybox-overlay").click();
});
});
</script>
<li class="fancybox-outer"><a id="inline" href="#hover-image_0" class="fancybox">
<img src="1_s.jpg" style="margin-top: 32px" />
</a>
<p>
Go to Yahoo</p>
<div style="display: none;">
<div id="hover-image_0">
<a href="http://www.yahoo.com">
<img src="1_b.jpg" class="img" />
</a>
</div>
</div>
</li>
<li class="fancybox-outer"><a id="inline" href="#hover-image_1" class="fancybox">
<img src="2_s.jpg" style="margin-top: 32px" />
</a>
<p>
Go to Google</p>
<div style="display: none;">
<div id="hover-image_1">
<a href="http://www.google.com">
<img src="2_b.jpg" class="img" /></a></div>
</div>
</li>
</body>
</html>
I having the same problem with Fancybox. You cannot have spaces or special character in href and div id. Use an URL slug if you are using page titles.
I was checking out all the possibilities and ran into the EXTRA case sensitivity issue as #BrettBumeter mentioned.
In fact, it is "so much case sensitive", I had to revrite the URL (href) path to my images from *.jpg to *.JPG (or whatever your file type extension might be).
Altering this solved my issue.
Don't apply the fancybox class to your LI element, do it to your A element.
I, after taking the above advice, changed ".png" to ".PNG" in the href. NOTE that the file names are a lower case extension but it only works with upper case extension in the href (rest of filename same)
Hope this helps.
My problem was giving inappropriate path to image e.g;
<a data-fancybox="gallery" href="../dist/imgs/nature/n1.png">
<img src="../dist/imgs/nature/n1.png"></a>
While the images loaded well locally, It could not do online.
Correcting the path solved the problem.
<a data-fancybox="gallery" href="imgs/nature/n1.png">
<img src="imgs/nature/n1.png"></a>
If you are trying to make Fancybox work with dynamic content, you may check this.
I was using the following code:
<a class="video__overlay" data-fancybox="gallery" href="<?= $blog_url ?>"></a>
My issue was that I was generating $blog_url dynamically, looking at a specific text file line, so a \n was being added at the end of $blog_url, without me noticing this.
So, I used trim() and everything works as expected.
