countdown is not counting down as expected - javascript

Hoping for some help with this, as I'm not exactly a js expert.
I have a countdown set up, adapted from Keith Wood's countdown. It's not counting down in any browser, though it seems to be functioning perfectly in every other regard.
Here she is on jfiddle.
And here's the code:
html:
<div id="form">
<div id="topbox">
<div class="countdown"></div>
<div id="until">
until move-in
</div>
</div>
</div>
js:
$(document).ready(function() {
//preload rollover image
var image = $('<img />').attr('src', '../../images/countdown_button1.png');
// jqueryUI calls for buttons
$(".back a").button({
icons: {primary: "ui-icon-triangle-1-w"}
});
// checklist button rollover
$('#bottombox a').hover(
function () {
$('#bottombox').addClass("button").removeClass("nobutton");
}, function () {
$('#bottombox').addClass("nobutton").removeClass("button");
}
);
// start instance of countdown
$('.countdown').countdown({until: new Date(2014, 9-1, 21, 10), layout:
'<ul class="countdown-tabs"><li><a>{dn} <span>{dl}</span></a></li>' +
'<li><a>{hn} <span>{hl}</span></a></li>' +
'<li><a>{mn} <span>{ml}</span></a></li>' +
'<li class="last-child"><a>{sn} <span>{sl}</span></a></li></ul>'});
$('.bg-switcher input').change(function () {
// set background photo to value of photo-switcher
window.location.hash = $(this).attr('id');
var photo = "url('/images/countdown_" + $(this).attr('id') + ".jpg')";
$('#canvas').css('background-image', photo);
});
});
function setPhoto() {
if(window.location.hash === "" || window.location.hash === "#one") {
$('#one').attr("checked", "checked");
$(".bg-switcher").buttonset();
} else {
// grab the value of the URL hash
var urlHash = window.location.hash.substring(1);
// set background photo to value in URL hash
var urlPhoto = "url('/images/countdown_" + urlHash + ".jpg')";
$('#canvas').css('background-image', urlPhoto);
$('#' + urlHash).attr("checked", "checked");
$(".bg-switcher").buttonset();
}
};
I'm also calling:
<script type="text/javascript" src="//ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>
<script type="text/javascript" src="//ajax.googleapis.com/ajax/libs/jqueryui/1.10.4/jquery-ui.min.js"></script>
<script type="text/javascript" src="/js/jquery.countdown.js"></script>
<script type="text/javascript" src="/js/jquery.plugin.js"></script>
Any ideas on how to get it to count down? Appreciate it!

You don't look like calling the actual countdown script as indicated on the website you took the script from:
~2. Download and include the jQuery Countdown CSS and JavaScript in the head section of your page.
<link rel="stylesheet" type="text/css" href="css/jquery.countdown.css">
<script type="text/javascript" src="js/jquery.plugin.js"></script>
<script type="text/javascript" src="js/jquery.countdown.js"></script>
EDITED: Other than that, check the developer tool of your browser for errors and try to fix them all. They might not be related directly to this, but they may prevent the execution of the rest of the script.

Disable Fancybox for specific images

I don't know Javascript but I'm using it to run Fancybox. There is no wordpress involved. It seems the way Fancybox works is by targeting any and all images, but for things like social media icons in my footer, I don't want targeted by Fancybox. Is there a simple way to turn off Fancybox on specific images?
Any help is greatly appreciated!
This is the Javascript I have pasted in my html.
<script type="text/javascript" src="http://code.jquery.com/jquery-1.11.0.min.js"></script>
<script type="text/javascript" src="http://code.jquery.com/jquery-migrate-1.2.1.min.js"></script>
<script type="text/javascript" src="http://cdnjs.cloudflare.com/ajax/libs/fancybox/1.3.4/jquery.fancybox-1.3.4.pack.min.js"></script>
<script type="text/javascript">
$(function($){
var addToAll = true;
var gallery = true;
var titlePosition = 'inside';
$(addToAll ? 'img' : 'img.fancybox').each(function(){
var $this = $(this);
var title = $this.attr('title');
var src = $this.attr('data-big') || $this.attr('src');
var a = $('').attr('href', src).attr('title', title);
$this.wrap(a);
});
if (gallery)
$('a.fancybox').attr('rel', 'fancyboxgallery');
$('a.fancybox').fancybox({
titlePosition: titlePosition
});
}); </script>
Change the addToAll from true to false. That way fancybox will just be added to images having the .fancybox class.

Failed to execute 'appendChild' on 'Node': The new child element is null

This weird bug is bugging me from half an hour. I am dynamically trying to apply a slider using only JavaScript. Any idea as to why this is occurring to me? I could find other questions on SO, but could not understand the solution. I am new to JS and highly appreciate if someone could explain me things in laymen terms. Here is my code.
MARKUP
<!DOCTYPE html>
<html>
<head>
<title>JS sample test page</title>
<link rel="stylesheet" type="text/css" href="jquery.bxslider.css">
</head>
<body>
<div class="og-fullimg"></div>
<script type="text/javascript" src="jquery-1.11.1.js"></script>
<script type="text/javascript" src="jquery.bxslider.min.js"></script>
<script type="text/javascript" src="main.js"></script>
</body>
</html>
JAVASCRIPT
// code for thumbnail slider begins
(function() {
var ogImg = document.getElementsByClassName("og-fullimg");
alert(ogImg.length);
var bxSlider = document.createElement("ul"); //created ul
bxSlider.setAttribute("class", "bxslider"); // gave a class name bxslider.
for (i = 1; i < 4; i++) {
var itemsList = document.createElement("li");
var linkImages = document.createElement("img");
linkImages.src = "images/bid_" + i + ".jpg";
itemsList.appendChild(linkImages);
bxSlider.appendChild(itemsList);
}
ogImg[0].appendChild(bxSlider);
document.body.appendChild(ogImg); //append everything to the body.
//call the slider.
$(document).ready(function() {
$('.bxslider').bxSlider({
auto: true,
pager: false,
adaptiveHeight: true,
slideWidth: 550
});
});
}());
// code for thumbnail slider ends.
Thanks in advance.
Several issues here:
document.body.appendChild(ogImg); is just wrong. ogImg is a nodeList. You can't directly append a nodeList to the body AND it's already in the DOM (you just got it with document.getElementsByClassName("og-fullimg");.
You are using $(document).ready() to wait to call .bxSlider(), but NOT using it to call document.getElementsByClassName(). My guess would be your code is just running too soon. If that is the case, then just put all your code inside the .ready() handler.
You're using a very odd mix of plain javascript and jQuery when switching the plain javascript over to jQuery could make your code smaller and more consistent. If you have jQuery, you may as well use it for what it's good at (which is selectors and operations on collections - among other things).
This is what I'd suggest:
//create and initialize the slider.
$(document).ready(function() {
var bxSlider = $("<ul class='bxslider'></ul>"), img;
for (var i = 1; i < 4; i++) {
img = new Image();
img.src = "images/bid_" + i + ".jpg";
$("<li>").append(img).appendTo(bxSlider);
}
bxSlider.appendTo(".og-fullimg");
bxSlider.bxSlider({
auto: true,
pager: false,
adaptiveHeight: true,
slideWidth: 550
});
});

That usually means that you have to import jquery at the top like this:
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
Edit: Here is the link for the updated version. I believe that this page will always update to the latest version of jQuery whereas my above answer won't: HERE
Check your script source path. It's likely not loading in.
If it's at the root of a site use:
<script type="text/javascript" src="/wpscripts/jquery-1.4.1.min.js"></script>
I see you have also tagged ASP.NET, so If it's in a control or somewhere that can be different for each page load, then use the following to have .Net figure out the actual relative path.
<script type="text/javascript" src="<%= ResolveClientUrl("~/wpscripts/jquery-1.4.1.min.js") %>"></script>
I see you are using WordPress.
You often are not able to define links with a relative path.
try using the php function "get_theme_root();" to get the theme root and navigate from there

Javascript Gallery that automatically uses all large images on page

I have a site with lots of images on one large page.
The easiest would be a Script that i could include, that automatically searches through that same page and uses all images larger than 100px to create a slideshow gallery from them.
Anyone knows such an easy script, that doesent need any programming skills?
I found this for a start:
jQuery get all images within an element larger than a specific size
To get all images larger that some size you can use something like this:
var allImages = $('img', yourDivElement)
var largeImages = allImages.filter(function(){
return ($(this).width() > 70) || ($(this).height() > 70)
})
Update:
After some more research, I found this the most fitting: Fancybox Gallery
It should be implemented on this page:
http://www.kathrinhoffmann.com/
It really depends on what is your favourite lightbox ("gallery opener"). Let's say thatyou like ShadowBox. It requires rel="shadowbox[gallery-name]" in which the gallery name is optional. The fun side of shadowbox is that lightbox instead of shadowbox will work as well.
What you then need to do is to add a link-tag around the images with this rel attribute.
var img = $("img"),
a = "<a href='",
b = "' rel='lightbox[",
galName = "chooseName",
c = "]'>";
img.each(function() {
var $this = $(this);
if ($this.width() > 100 || $this.height() > 100) {
$this.wrap(a + $this.attr("src") + b + galName + c);
}
});
Fiddle.
Have you tried doing something like this to get the original width and height of an image:
// loop through img elements
$('.img-class').each(function(){
// create new image object
image = new Image();
// assign img src attribute value to object src property
image.src = $(this).attr('src');
// function that adds class to image if width and height is greater that 100px
image.onload = function(){
// assign width and height values
var width = this.width,
height = this.height;
// if an image is greater than 100px width and height assign the
// string fancybox to image object className property
image.className = (width > 100 && height > 100) ? 'fancybox' : '';
}
});
#Bram Vanroy is almost right, but you need to take care about the real size (non affected by CSS or so) and about non loaded images (that's why my filters needs a callback to return the filtered images):
http://jsfiddle.net/coma/wh44u/3/
$(function() {
$('img').filterBiggerThan(100, function(big) {
console.log(big);
});
});
$.fn.filterBiggerThan = function (limit, callback) {
var imgs = [];
var last = this.length - 1;
this.each(function(i) {
var original = $(this);
var img = $('<img/>')
.appendTo('body')
.css({maxWidth: 'none'})
.load(function(event) {
if(img.width() > limit || img.height() > limit) {
imgs.push(original);
}
img.remove();
if(i >= last) {
callback(imgs);
}
});
img.attr('src', this.src);
});
};
Here you have another example:
http://jsfiddle.net/coma/NefFM/22/
Here you have a Fancybox gallery as Bram suggested:
http://jsfiddle.net/coma/NefFM/32/
Nothing stops you from wrapping your images (that you already found) with required markup and passing em to fancybox:
largeImages.each(function(){
$(this).wrap('<a></a>').parent().attr({'rel':'gallery', href: this.src});
});
$('a[rel=gallery]').fancybox();
You can see the working demo in this fiddle (beware I used body as root element for finding images in demo, you better add some class/attribute to the element that holds all the images you want to work with and use it instead).
Thanks,
I solved it like this:
I downloaded fancybox and added this code from the fancybox instructions at the bottom of my page at kathrinhoffmann.com :
<!-- Add jQuery library -->
<script type="text/javascript" src="http://code.jquery.com/jquery-latest.min.js"></script>
<!-- Add mousewheel plugin (this is optional) -->
<script type="text/javascript" src="/fancybox/lib/jquery.mousewheel-3.0.6.pack.js"></script>
<!-- Add fancyBox -->
<link rel="stylesheet" href="/fancybox/source/jquery.fancybox.css?v=2.1.4" type="text/css" media="screen" />
<script type="text/javascript" src="/fancybox/source/jquery.fancybox.pack.js?v=2.1.4"></script>
<!-- Optionally add helpers - button, thumbnail and/or media -->
<link rel="stylesheet" href="/fancybox/source/helpers/jquery.fancybox-buttons.css?v=1.0.5" type="text/css" media="s$
<script type="text/javascript" src="/fancybox/source/helpers/jquery.fancybox-buttons.js?v=1.0.5"></script>
<script type="text/javascript" src="/fancybox/source/helpers/jquery.fancybox-media.js?v=1.0.5"></script>
<link rel="stylesheet" href="/fancybox/source/helpers/jquery.fancybox-thumbs.css?v=1.0.7" type="text/css" media="sc$
<script type="text/javascript" src="/fancybox/source/helpers/jquery.fancybox-thumbs.js?v=1.0.7"></script>
<script type="text/javascript">
$(document).ready(function() {
$(".fancybox").fancybox();
});
</script>
Then I included my own script:
<script type="text/javascript" src="/add_fancybox.js"></script>
which looks like this:
var img = $("img"),
a = "<a href='",
b = "' rel='group' class='fancybox'>";
img.each(function() {
var $this = $(this);
if ($this.width() > 50 && $this.height() > 50) {
$this.wrap(a + $this.attr("src") + b);
}
});

Why isn't Bootstrap's scrollspy working?

I have a simple Bootstrap modal setup, and in the modal I have content with a nav and scrollspy set up. However, it isn't working. I see it gets activated, but the nav is never updated.
The full source is too long for here and you wouldn't be able to see the effect I am getting, so I have set up a jsfiddle
I am using the data-spy="scroll" method to enable it. What have I done wrong? Why isn't the nav being update with your position?
bootstrap scrollspy still has some bugs (i really love bootsrap at all).
i use a custom script for this it works way better and is more flexible:
<script type="text/javascript">
$(document).ready(function(){
var lastId, topMenu = $(".menu-sidebar"),
topMenuHeight = topMenu.outerHeight() + 150,
menuItems = topMenu.find("a"),
scrollItems = menuItems.map(function() {
var item = $($(this).attr("href"));
if (item.length) {
return item;
}
});
menuItems.click(function(e) {
var href = $(this).attr("href"),
topMenuHeight = topMenu.outerHeight() + 20,
offsetTop = href === "#" ? 0 : $(href).offset().top - topMenuHeight + 1;
$('html, body').stop().animate({
scrollTop: offsetTop
}, 300);
e.preventDefault();
});
$(window).scroll(function() {
var fromTop = $(this).scrollTop() + topMenuHeight;
var cur = scrollItems.map(function() {
if ($(this).offset().top < fromTop) return this;
});
cur = cur[cur.length - 1];
var id = cur && cur.length ? cur[0].id : "";
if (lastId !== id) {
lastId = id;
menuItems.parent().removeClass("active").end().filter("[href=#" + id + "]").parent().addClass("active");
}
});
});
</script>

Hey I think there are two issues here:
(1) putting scrollspy on something other than the body causes problem. Check out this:
In Twitter Bootstrap's ScrollSpy, where exactly can I put data-spy="scroll"?
basically if you add:
#area-to-watch {
height: 200px;
overflow: auto;
}
it will you allow you to scrollspy to "spy" on something other than the body.
http://jsfiddle.net/hajpoj/SZYKM/
This a modified version of your jsfiddle
(2) Putting scrollspy into a model causes more problems. If you put the above into a model, it kind of freaks out.
I'm not positive but I think you need to do something like
.scrollspy('refresh')
stated in the docs http://twitter.github.com/bootstrap/javascript.html#scrollspy
Please make sure that your bootstrap folder contains all the .js files required for ScrollSpy
In my case my bootstrap folder (bootstrap/js/) has the following files :
<script src="bootstrap/js/jquery.js"></script>
<script src="bootstrap/js/bootstrap-transition.js"></script>
<script src="bootstrap/js/bootstrap-alert.js"></script>
<script src="bootstrap/js/bootstrap-modal.js"></script>
<script src="bootstrap/js/bootstrap-dropdown.js"></script>
<script src="bootstrap/js/bootstrap-scrollspy.js"></script>
<script src="bootstrap/js/bootstrap-tab.js"></script>
<script src="bootstrap/js/bootstrap-tooltip.js"></script>
<script src="bootstrap/js/bootstrap-popover.js"></script>
<script src="bootstrap/js/bootstrap-button.js"></script>
<script src="bootstrap/js/bootstrap-collapse.js"></script>
<script src="bootstrap/js/bootstrap-carousel.js"></script>
<script src="bootstrap/js/bootstrap-typeahead.js"></script>
<script src="bootstrap/js/bootstrap-affix.js"></script>
<script src="bootstrap/js/holder/holder.js"></script>
<script src="bootstrap/js/google-code-prettify/prettify.js"></script>
<script src="bootstrap/js/application.js"></script>
You should call .scrollspy('refresh') after the modal has been shown like this:
$('#myModal').on('shown.bs.modal', function (e) {
$('.modal-body').scrollspy('refresh');
});
