jquery function doesn't trigger

My resizeAreas function doesn't trigger in $(document).ready function. Here's the link to the app. I have also tried $(document).load but same result.
This problem is not consistent. But most of the time the page doesn't load correctly. If the list of task have the same height and 4 equal(as height) lists on the row then they are loaded correctly else they're not. To make sure that you see how it must look you can move a task element from one list to another. I don't have the reputation to post images.
Here is most of the javascript code:
function makeDropArea() {
var widthArea = $(".taskListing").width() / 2 - 55;
var heightArea = $(".taskListing").height();
$('.dropArea').width(widthArea);
$('.dropArea').css('margin-left', 5 + 'px');
$('.generalInfo').css('margin-left', 5 + 'px');
$('.generalInfo').css('width', widthArea * 2 + 220 - 45);
$('.subTaskHeader').css('width', widthArea + 25);
}
function makeDropElement(){
var widthEl = $('.dropArea').width() + 25 ;
$('.task').width(widthEl);
}
function taskListingSize(){
var width = getWidth();
var height = getHeight() * 80 / 100;
$('.taskListing').css('width', width);
}
function resizeAreas() {
$('.taskListing').each(function(){
var highestBox = 0;
$('.dropArea', this).each(function(){
if($(this).height() > highestBox)
highestBox = $(this).height();
});
$('.dropArea',this).css('min-height', highestBox);
});
}
$(document).ready(function () {
menu();
taskListingSize();
makeDropArea();
makeDropElement();
resizeAreas(); //<-- this is the one with the problems
$(".dropArea").resize(resizeAreas());
$( window ).resize(function() {
taskListingSize();
makeDropArea();
makeDropElement();
});
});
Thanks.
Update 1:
I've done some more testing and this bug is only on chrome and firefox but not on IE. The problem appears only on the openshift platform.

Either change:
$(".dropArea").resize(resizeAreas());
To:
$(".dropArea").resize("resizeAreas");
Or:
$(".dropArea").resize(function(){
resizeAreas();
});

I think it should be
$(".dropArea").resize(resizeAreas);
Or
$(".dropArea").resize(function(){
resizeAreas();
});

making a function works on specific widths

I am trying to make this function works only when the screen size is above 1024px.
//Parallax background image
var velocity = 0.5;
function update(){
var pos = $(window).scrollTop();
$('.parallax').each(function() {
var $element = $(this);
var height = $element.height();
$(this).css('background-position', '40%' + Math.round((height - pos) * velocity) + 'px');
});
};$(window).bind('scroll', update); update();
Here is what I have tried to do:
//Parallax background image
var velocity = 0.5;
$(window).on("ready resize", function() {
if ($(window).width() < 770) {
function update(){
var pos = $(window).scrollTop();
$('.parallax').each(function() {
var $element = $(this);
var height = $element.height();
$(this).css('background-position', '40%' + Math.round((height - pos) * velocity) + 'px');
});
};});$(window).bind('scroll', update); update();
I really don't know what I am doing wrong...

You haven't stated what the problem you're coming across is. If it's "my code doesn't work", then perhaps you should check your syntax first. Your braces are messed up.
//Initialize velocity and empty update function
var velocity = 0.5;
var update = function () {};
//When window is ready (content loaded) OR resized, execute the following function
$(window).on("ready resize", function () {
if ($(window).width() >= 1024) { //Check if window width is 1024px wide or larger
update = function () { //Set update to run this function when executed.
var pos = $(window).scrollTop(); //Get scrollbar position https://api.jquery.com/scrollTop/
//For each element with 'parallax' class, execute the following function
$('.parallax').each(function () {
var $element = $(this); //Get the current parallax-classed element
var height = $element.height(); //Save the current height of this element
//Set the CSS of this parallax-classed element set the background position
$(this).css('background-position', '40% + ' + Math.round((height - pos) * velocity) + 'px');
});
};
} else { //Execute if screen width is < 1024px
update = function () {}; //Set update to do nothing
}
});
//When window is scrolled through, run the update function
$(window).bind('scroll', update);
//update();
Last line is unnecessary, as resize will handle function value, and scroll will handle the execution.
You were missing a + or - within the background-position setting.
So for example, if the result of your Math.round() was "30", then Javascript would interpret that line as $(this).css('background-position', '40%30px'); which obviously would cause issues. I'm sure you wanted it to say something like $(this).css('background-position', '40% + 30px');.

IE Doesn't run remote JS properly but local runs fine

My page works in every browser except in IE 10. When I run this page locally in IE 10 there seems to be no problem whatsoever, only when I open the page remotely with IE 10.
The JavaScript is supposed to measure the div with main text and set the height and width of the div's that are off-screen. This is done wrong by IE 10. The width of these div's has to be set because otherwise the will not animate in properly when an item from the menu is clicked.
I did a check on deprecated functions but found none.
I checked the syntax and nothing wrong there. (as far as i can see)
The console in IE does not report any errors.
Anyone any idea as for why locally it works fine in every browser, but remotely the only browser that displays it faulty is IE?
EDIT:
I have removed the function brackets at init so the DOM can initiate, although this did not fix the problem.
script (embedded in the head of the page):
<script src="scripts/jquery-1.10.1.min.js"></script>
<script>
var mainTextDiv = null;
var animate;
var acc = 0;
var currentTab = "home";
var nextTab;
var working = 0;
var bar = 600;
var divW;
function init(){
onWC(currentTab);
document.getElementById(currentTab).style.width = 'auto';
divW = document.getElementById(currentTab).offsetWidth;
document.getElementById("home").style.width = divW + "px";
document.getElementById("profile").style.width = divW + "px";
document.getElementById("news").style.width = divW + "px";
document.getElementById("forums").style.width = divW + "px";
document.getElementById("webshop").style.width = divW + "px";
document.getElementById("status").style.width = divW + "px";
}
function onWC(tab){
var divh = document.getElementById(tab).offsetHeight;
document.getElementById('tabcontainer').style.height = ( divh + 50 ) + "px";
}
function moveDiv(tabName){
if (currentTab == tabName){
return;
}
if (working == 1){
return;
}
working = 1;
nextTab = tabName;
removeDiv();
}
function removeDiv(){
mainTextDiv = document.getElementById(currentTab);
mainTextDiv.style.left = parseInt(mainTextDiv.style.left) + (0.5+acc) + "px";
if (parseInt(mainTextDiv.style.left) > 2000){
mainTextDiv.style.left = 2000 + "px";
onWC(nextTab);
getDiv();
return;
}
acc += 0.15;
animate = setTimeout(removeDiv,10);
}
function getDiv(){
mainTextDiv = document.getElementById(nextTab);
mainTextDiv.style.left = parseInt(mainTextDiv.style.left) - (0.5+acc) + "px";
if (parseInt(mainTextDiv.style.left) <= 0){
mainTextDiv.style.left = 0 + "px";
currentTab = nextTab;
working = 0;
return;
}
acc -= 0.15;
animate = setTimeout(getDiv,15);
}
window.onload = init;
window.onresize = init;
$(function() {
$("#menu ul li a").hover(
function(){
$(this).css("background-color", "#525252");
$(this).css("color", "#FFF");
},
function() {
$(this).css("background-color", "#FFF");
$(this).css("color", "#525252");
}
);
});
</script>

Change window.onresize = init(); to window.onresize = init;
As it stands, the init() is trying to run immediately when the JS file is loaded, which is throwing the error because the DOM hasn't loaded yet.

jQuery breaking in Firefox but no other browser

I have the following code which works fine in all browsers including Firefox:
var top;
var imageHeight;
function upFunction() {
top = parseInt($(".feature img").css("top"));
imageHeight = $(".feature img").height();
if (top > (imageHeight - 335) * -1) {
$(".feature img").css("top", top - 1 + "px");
$("#topPos").val(top - 1);
}
};
$(document).ready(function() {
$("a#up").mousedown( function(e) {
e.preventDefault();
upFunction();
timeoutId = setInterval( upFunction, 100 );
}).bind('mouseup mouseleave', function() {
clearInterval(timeoutId);
});
});
However there's obviously something else in my page which is causing this not to work in firefox and I can't work it out.
Is there any way I can fond out what's causing it to break without removing everything from the page to find out what it is?
EDIT:
OK, with the help of Jai's answer, it appears that a small tweak to my code makes it work in Firefox. Here's what I did:
function upFunction() {
var top = parseInt($(".feature img").css("top"));
var imageHeight = $(".feature img").height();
if (top > (imageHeight - 335) * -1) {
$(".feature img").css("top", top - 1 + "px");
$("#topPos").val(top - 1);
}
};
and remove the 2 variables from the global scope. Not sure why it made a different but it did.

Try these fixed variable declarations:
function upFunction() {
var img = $(".feature img"),
top = parseInt(img.css("top"));
if (top > (335 - img.height())) {
img.css("top", top - 1 + "px");
$("#topPos").val(top - 1);
}
};
$(document).ready(function() {
var timeoutId;
$("a#up").mousedown( function(e) {
e.preventDefault();
upFunction();
timeoutId = setInterval( upFunction, 100 );
}).bind('mouseup mouseleave', function() {
clearInterval(timeoutId);
});
});
On your actual question: Debug your script via inspecting it in the developer tools (Firebug).

You should try this one:
function upFunction(top, imageHeight) {
if (top > (imageHeight - 335) * -1) {
$(".feature img").css("top", top - 1 + "px");
$("#topPos").val(top - 1);
}
}
$(document).ready(function() {
var top = parseInt($(".feature img").css("top"));
var imageHeight = $(".feature img").height();
$("a#up").mousedown( function(e) {
e.preventDefault();
upFunction(top, imageHeight);
timeoutId = setInterval(function(){
upFunction(top, imageHeight);
}, 100);
}).bind('mouseup mouseleave', function() {
clearInterval(timeoutId);
});
});

Don't use top as a var name in global scope, it's already used.
Try typing console.log(top) or alert(window.top) into your browser's console for reference.

Jquery slider help

ok so i have an interspire shopping cart so its hard to customize..
anyway,
here is a link to my code
http://jsfiddle.net/WTvQX/
im having trouble getting the scroll to work properly...
it works differently on my actual site here...
so i need help... re-doing it or just fixing..
let me kno

You need to add the "relatedLeft" ID to the left button, however try something like this...
Demo: http://jsfiddle.net/wdm954/WTvQX/3/
$('#relatedRight').click(function() {
$('#scool').animate({left: "+=100px"}, 'slow');
});
$('#relatedLeft').click(function() {
$('#scool').animate({left: "-=100px"}, 'slow');
});
You can adjust pixel distance and speed to your liking.
EDIT: Try something like this. The first part finds the width of all the images. Then the animates only fire when the offset is within range.
Demo: http://jsfiddle.net/wdm954/WTvQX/5/
var w = 0;
$('#scroll img').each(function (i, val) {
w += $(this).width();
});
$('#relatedRight').click(function() {
var offset = $('#scroll').offset();
if (offset.left < w) {
$('#scroll').animate({left: "+=100px"}, 'slow');
}
});
$('#relatedLeft').click(function() {
var offset = $('#scroll').offset();
if (offset.left > -w) {
$('#scroll').animate({left: "-=100px"}, 'slow');
}
});
EDIT: One more code option here. This one will stop scrolling sooner (note there are CSS changes here also).
Demo: http://jsfiddle.net/wdm954/WTvQX/7/
var w = 0;
$('#scroll img').each(function (i, val) {
w += $(this).width();
w += parseFloat($(this).css('paddingRight'));
w += parseFloat($(this).css('paddingLeft'));
w += parseFloat($(this).css('marginRight'));
w += parseFloat($(this).css('marginLeft'));
});
$('#scroll').css('width', w + 'px');
$('#relatedRight').click(function() {
var offset = $('#scroll').offset();
if (offset.left < 0) {
$('#scroll').stop().animate({left: "+=100px"}, 'slow');
}
});
$('#relatedLeft').click(function() {
var offset = $('#scroll').offset();
var b = $('#bar').width();
if (offset.left > b-w) {
$('#scroll').stop().animate({left: "-=100px"}, 'slow');
}
});
