console.log and .scroll listener does not work

I'm trying to create this parallax effect on a landing page. Also following this tutorial https://www.youtube.com/watch?v=WTZpNAbz3jg (skip to 21:00) for the jquery.
I am now creating the jquery side of the site, but I already have a js file for this site, and created a new one for the landing page(also tried to place the code on my main js file. But anyways, to test out the listener and console, i have this code.
$(window).scroll(function(){
console.log('h1')
});
Also here is the code inside my main js file
$(document).ready(function(){
$("#graphics").hide();
$("#morew").hide();
//------------landing scroll---------------//
$(window).scroll(function(){
console.log('h1')
});
//------------Toggle---------------//
$("#hideshow1").click(function(){
$("#photography").slideToggle("slow");
$("#graphics").slideUp("slow");
});
$("#hideshow2").click(function(){
$("#graphics").slideToggle("slow");
$("#photography").slideUp("slow");
});
$("#hsw").click(function(){
$("#morew").slideToggle("slow")
});
$("#hsw2").click(function(){
$("#morew").slideUp("slow")
});
//------------before and after---------------//
//------------carousel---------------//
//------------before and after functions---------------//
$(".top").css("width", "50%");
$(".ba").mousemove(function(e){
// get the mouse x (horizontal) position and offset of the div
var offset = $(this).offset();
var iTopWidth = (e.pageX - offset.left);
// set width of bottomimage div
$(this).find(".top").width(iTopWidth);
});
//-----------lightbox/fancybox js---------------//
$('.fancybox-thumbs').fancybox({
prevEffect : 'none',
nextEffect : 'none',
closeBtn : false,
arrows : false,
nextClick : true,
helpers : {
thumbs : {
width : 50,
height : 50
}
}
});
});
But apparently neither works, also here is the script link from my html
<script type="text/javascript" src="js\jquery.js"></script>
<script type="text/javascript" src="js\script2.js"></script>
<script type="text/javascript" src="js\landing.js" defer></script>
<link rel="stylesheet" href="CSS\style2.css">
I also tried placing the "landing.js" script tag before the closing html tag, and tried to add "defer", but nothing works. If anyone can help it would be much appreciated, also I'm sorry I'm just starting with java/jQuery.
BASICALLY: I just wanna know why the scroll listener wont work, I created another site, just to test it out and it works fine.

Does this do what you want it to do?
https://jsfiddle.net/6rp7g3kn/
uses window.onscroll without the need for jQuery:
window.onscroll = function(){
$("#message").text(window.scrollY);
};

Jquery Hover not working in Firefox or IE

I'm new to Javascript/Jquery so go easy!
I've created what will be an HTML facebook tab, with some images and applied a hover effect so that they expand as the mouse hovers over. This seems to work fine in Chrome but in Firefox and IE it's glitchy and the animation seems to run repeatedly unless the cursor is dead centre over the image.
I've tried adding "stop()" in there but either it doesn't work or I'm putting it in the wrong place (probably the latter). If anyone has any suggestions I would be very grateful!
<script>
$(document).ready(function() {
$('.circle').hover(function() {
$(this).animate({
'position' : 'relative',
'width' : 120,
'height' : 120,
'border-radius' : 60,
'margin' : 20,
'top' : 0,
});
}, function() {
$(this).animate({
'position' : 'relative',
'width' : 100,
'height' : 100,
'margin' : 25,
'top' : 10,
});
});
});
</script>
Full example available here:

Thanks in advance.

You can use e.stoppropagation() function to stop bubbling.
Eg.stoppropagation
<div id="noStop">
<span>This one doesn't stop bubbling</span>
<ul></ul>
</div>
<div id="stop">
<span>This one stops bubbling</span>
<ul></ul>
</div>

Reload jQuery Carousel on window resize to change orientation from vertical to horisontal

I'm creating a gallery for a responsive lay-out - I am using jQuery Riding Carousels for the thumbnails.
When the window is re-sized to smaller than 1024px, the orientation of the carousel needs to change from vertical to horizontal ...
I'm doing it like this at present:
<script type="text/javascript">
jQuery(document).ready(function() {
jQuery('#mycarousel').jcarousel({
vertical: $(window).width() > 1008,
scroll: 3,
});
});
</script>
... the JS simply hooks up a class, but it doesn't do so if you re-size the browser window by dragging it - you need to refresh the page.
Is there a way to destroy the script and re-initialize it on the fly?

Please check Working exmpale: http://codebins.com/bin/4ldqpba/1/Jcarousel%20vertical%20on%20resize
Tested in all browsers and works perfectly fine. bounty is mine :)
In the example i have give threshold widht 350 you can test it by resizing the result pane and as soon as you start havin horizontal scroll bar it will converted to vertical.
1 possible issue depending on your requirement is if you ahve any handlers on images they will be gone after changing display way. the solution for it is wrap your #mycarousel in a div and use Jquery delegate to handle events on the wrapper so no issue with events also.
Let me know if you come under this situation.
Following code is exactly as per your need.
When the window is re-sized to smaller than 1024px, the orientation of the carousel needs to change from vertical to horizontal .
which is revers form the example as for me it makes more sense if width is less make it vertical.
jQuery(document).ready(function() {
var widthCheck = 1008;
var resizeTimer = null,
verticalFlg = $(window).width() > widthCheck;
var obj = jQuery('#mycarousel').clone();
$('#mycarousel').jcarousel({
vertical: verticalFlg,
scroll: 2
});
jQuery(window).resize(function() {
resizeTimer && clearTimeout(resizeTimer); // Cleraring old timer to avoid unwanted resize calls.
resizeTimer = setTimeout(function() {
var flg = ($(window).width() > widthCheck);
if (verticalFlg != flg) {
verticalFlg = flg;
$('#mycarousel').closest(".jcarousel-skin-tango").replaceWith($(obj).clone());
$('#mycarousel').jcarousel({
vertical: verticalFlg,
scroll: 2
});
}
}, 200);
});
})

Or you can look at the source. I'm guessing you are using version 0.2
Looking at the source
https://github.com/jsor/jcarousel/blob/0.2/lib/jquery.jcarousel.js
we can see that there are two lines (80 and 81) which are only done in object init. Those lines are
this.wh = !this.options.vertical ? 'width' : 'height';
this.lt = !this.options.vertical ? (this.options.rtl ? 'right' : 'left') : 'top';
also this line at 149
if (!this.options.vertical && this.options.rtl) {
this.container.addClass('jcarousel-direction-rtl').attr('dir', 'rtl');
}
It might be if you add those to the callback you will get better results.
You could also try version 0.3 of the plugin.
Prior answer:
Can't test it myself right now, but try this:
<script type="text/javascript">
jQuery(document).ready(function() {
jQuery('#mycarousel').jcarousel({
vertical: $(window).width() > 1008,
scroll: 3,
reloadCallback: function () {
this.options.vertical = $(window).width() > 1008;
},
});
});
</script>

<script type="text/javascript">
jQuery(document).ready(function() {
var sizeCheck = function() {
return $(window).outerWidth() >= 1024
}
jQuery('#mycarousel').jcarousel({
vertical: sizeCheck(),
scroll: 3,
});
var jCarousel = jQuery('#mycarousel').data('jcarousel');
window.onresize = function() {
jCarousel.options.vertical = sizeCheck(); // maybe you have to access the option through jCarousel.plugin.options.vertical
jCarousel.reset();
}
});
</script>
Maybe this works.

I haven't tested the following code, but I am fairly sure the following code should work:
<script type="text/javascript">
var carousel;
jQuery(window).resize(function() {
if(carousel !== undefined) carousel.destroy();
carousel = jQuery('#mycarousel').jcarousel({
vertical: $(window).width() > 1008,
scroll: 3,
});
});
</script>
or even better something along the lines of:
<script type="text/javascript">
var carousel;
jQuery(document).ready(function() {
carousel = jQuery('#mycarousel').jcarousel({
vertical: $(window).width() > 1008,
scroll: 3,
});
});
jQuery(window).resize(function() {
//NOT SURE WHICH OF THE BELOW LINES WOULD WORK, try both and check which works
carousel.options.vertical = $(window).width() > 1008;
carousel.vertical = $(window).width() > 1008;
carousel.reload();
});
</script>
If it does not, you should add a console.log(carousel) to your code and check out what the prototype is of the outputted value (check F12). There should be something along the lines of destroy (or alternatively check console.log($.jcarousel())).

javascript - position not being set properly on page load

I am creating a coverflow plugin but I have a slight problem when it first loads.
The size/styles of the images is set based on their position in the coverflow. When the page first loads the images all resize properly but they do not reposition themselves. If I them use the left and right navigation they work correctly.
I am not sure what is causing this. I thought it might be something to do with the variable that sets the starting position of the coverflow...
Here's my code:
<script type="text/javascript" src="/scripts/jquery-ui.js"></script>
<script type="text/javascript">
$(document).ready(function() {
var coverflowPos = Math.round($('#coverflow img').length / 2)
$('#coverflow img').each( function(i) {
$(this).css({'opacity' : 1-(Math.abs(coverflowPos-i)*0.4), 'z-index' : 100-(Math.abs(coverflowPos-i)) }).width(200-(Math.abs(coverflowPos-i)*50)).height(128-(Math.abs(coverflowPos-i)*50));
});
// If I run the testme() function here, it animates to the right place but I want it to start in this position rather than animate to it
$('#moveLeft').click( function() {
if(coverflowPos > 1) {
coverflowPos = coverflowPos-1
}
testme();
});
$('#moveRight').click( function() {
if(coverflowPos < $("#coverflow img").length -1) {
coverflowPos = coverflowPos+1
}
testme();
});
function testme() {
$('#coverflow img').each( function(i) {
$(this).animate({
opacity: 1-(Math.abs(coverflowPos-i)*0.4),
width: 200-(Math.abs(coverflowPos-i)*50),
height: 128-(Math.abs(coverflowPos-i)*50)
}, {
duration: 500,
easing: 'easeInOutSine'
}).css({ 'z-index' : 100-(Math.abs(coverflowPos-i)) });
});
};
});
</script>
And here's a link to a jsfiddle:
http://jsfiddle.net/r8NqP/4/

Calling testme() at the end of the ready() function moves them into place. It does ease them in though, which looks a bit odd, could get rid of the ease in testme() by adding a doease parameter.

Check you fist each :
'z-index' : 100-(Math.abs(coverflowPos-i)) }).width(200-(Math.abs(coverflowPos-i)*50)).height(128-(Math.abs(coverflowPos-i)*50));
I think U mean:
'z-index' : 100-(Math.abs(coverflowPos-i)),
'width' : 200-(Math.abs(coverflowPos-i)*50),
'height': 128-(Math.abs(coverflowPos-i)*50)
Linke In your testme() function ?!
After that, you can also add a "Hack", by executing testme(true); at the end of script.
And add, in your testme() function , a test parameter to set the duration at 0 or simply disable animate and replace by CSS().
But, it just a Hack.

200-(Math.abs(coverflowPos-i)*50) may be less than 0 -- e.g.,
200-(5-0)* 50= 200 - 250 = -50
And the negative width ends up not being applied, leaving the width at its original 200px value. The opacity gets set properly, so all you get is a huge blank space where the image is.
var width = 200-(Math.abs(coverflowPos-i)*50);
if ( width < 0 ) width = 0;
covers the init nicely.
I haven't bothered to check why it's okay once it's animated -- my guess is, that the images were already small, so it's not as noticeable.

The problem came from "Each index", that not correctly used to compute the Width and Height of the first image.
Try this :
$('#coverflow img').each( function(i) {
i++;
$(this).css({...
And remove the Blank.gif...

Coda Slider Problem - Works in Firefox, Not Chrome/Safari

I am building a page that is employing several different javascript elements and I seem to have run into a problem I haven't before (not surprising as I am new to javascript).
I have implemented the tutorial for the JQuery Coda Slider located here: http://jqueryfordesigners.com/coda-slider-effect/.
It seems that the sliding effect works when I run it it Firefox but not Chrome or Safari. Wondering if this is a common issue and if I am missing something obvious.
To help, I am attaching the code of the page I am working on as it may help you understand the scripts I am using.
<head>
<title></title>
<link rel="stylesheet" href="stylesheets/style.css" media="screen" />
<script src="js/jquery-1.3.2.min.js" type="text/javascript"></script>
<script type="text/javascript" src="http://cloud.github.com/downloads/malsup/cycle/jquery.cycle.all.2.73.js"></script>
<script src= "js/banner.js"type="text/javascript"></script>
<script src="js/menu.js" type="text/javascript"></script>

<script src="js/jquery.serialScroll-1.2.2-min.js" type="text/javascript"></script>
<script src="js/slider.js" type="text/javascript"></script>
</head>
EDIT: slider.js
// when the DOM is ready...
$(document).ready(function () {
var $panels = $('#slider .scrollContainer > div');
var $container = $('#slider .scrollContainer');
// if false, we'll float all the panels left and fix the width
// of the container
var horizontal = true;
// float the panels left if we're going horizontal
if (horizontal) {
$panels.css({
'float' : 'left',
'position' : 'relative' // IE fix to ensure overflow is hidden
});
// calculate a new width for the container (so it holds all panels)
$container.css('width', $panels[0].offsetWidth * $panels.length);
}
// collect the scroll object, at the same time apply the hidden overflow
// to remove the default scrollbars that will appear
var $scroll = $('#slider .scroll').css('overflow', 'hidden');
// apply our left + right buttons
$scroll
.before('<img class="scrollButtons left" src="images/scroll_left.png" />')
.after('<img class="scrollButtons right" src="images/scroll_right.png" />');
// handle nav selection
function selectNav() {
$(this)
.parents('ul:first')
.find('a')
.removeClass('selected')
.end()
.end()
.addClass('selected');
}
$('#slider .navigation').find('a').click(selectNav);
// go find the navigation link that has this target and select the nav
function trigger(data) {
var el = $('#slider .navigation').find('a[href$="' + data.id + '"]').get(0);
selectNav.call(el);
}
if (window.location.hash) {
trigger({ id : window.location.hash.substr(1) });
} else {
$('ul.navigation a:first').click();
}
// offset is used to move to *exactly* the right place, since I'm using
// padding on my example, I need to subtract the amount of padding to
// the offset. Try removing this to get a good idea of the effect
var offset = parseInt((horizontal ?
$container.css('paddingTop') :
$container.css('paddingLeft'))
|| 0) * -1;
var scrollOptions = {
target: $scroll, // the element that has the overflow
// can be a selector which will be relative to the target
items: $panels,
navigation: '.navigation a',
// selectors are NOT relative to document, i.e. make sure they're unique
prev: 'img.left',
next: 'img.right',
// allow the scroll effect to run both directions
axis: 'xy',
onAfter: trigger, // our final callback
offset: offset,
// duration of the sliding effect
duration: 500,
// easing - can be used with the easing plugin:
// http://gsgd.co.uk/sandbox/jquery/easing/
easing: 'swing'
};
// apply serialScroll to the slider - we chose this plugin because it
// supports// the indexed next and previous scroll along with hooking
// in to our navigation.
$('#slider').serialScroll(scrollOptions);
// now apply localScroll to hook any other arbitrary links to trigger
// the effect
$.localScroll(scrollOptions);
// finally, if the URL has a hash, move the slider in to position,
// setting the duration to 1 because I don't want it to scroll in the
// very first page load. We don't always need this, but it ensures
// the positioning is absolutely spot on when the pages loads.
scrollOptions.duration = 1;
$.localScroll.hash(scrollOptions);
});

after hours searching and debugging I found out the solution. jQuery interfears with joomla included mootools. Remove it with the following code in your index.php header:
<?php
//remove mootools.js and caption.js
$headerstuff=$this->getHeadData();
reset($headerstuff['scripts']);
foreach($headerstuff['scripts'] as $key=>$value){
unset($headerstuff['scripts'][$key]);
}
$this->setHeadData($headerstuff);
?>

Why didn't you just copy "http://jqueryfordesigners.com/demo/coda-slider.html" Its a reduction of what you need. Remember you need these:
<script src="jquery-1.2.6.js" type="text/javascript"></script>
<script src="jquery.scrollTo-1.3.3.js" type="text/javascript"></script>
<script src="jquery.localscroll-1.2.5.js" type="text/javascript" charset="utf-8"></script>
<script src="jquery.serialScroll-1.2.1.js" type="text/javascript" charset="utf-8"></script>
<script src="coda-slider.js" type="text/javascript" charset="utf-8"></script>
And the HTML should be similar (view source to find out). It works great in Chrome.
