jQuery - Each counting resetting issue

I'm trying to get the currentpage number using jQuery each function. This is how I am doing it
var CurrentPageView = 1;
var check = true;
var Bookmark = [];
var CurPage = 1;
$(function() {
$(window).scroll(function() {
if (check) {
var PagesPosition = [];
var CurrentWindowPosition = $(window).scrollTop();
var CurrentCenterWindowPos = CurrentWindowPosition + $(window).height() / 2;
$(".Page").each(function() {
var PagePos = $(this).offset().top;
if (PagePos / CurrentCenterWindowPos <= 1) {
CurPage = $(this).index() + 1;
}
});
$(".CurrPageNumber").val(CurPage);
CurrentPageView = CurPage;
}
});
});
And it is working pretty well. If i am scrolling up and down he changes and gives me the currentpage number. The problem happens if between those with the class page there is something like a span. When this happens the counter resets to 1..
I would like to know if there is a way to keep the counting working for every div with the class "A4 Portrait" even if inside a span.
So instead of the actual count
1
2
1
2
It would be
1
2
3
4

Try using the index in the list of .Page instead of the index in its parent:
$(".Page").each(function(i) {
var PagePos = $(this).offset().top;
if (PagePos / CurrentCenterWindowPos <= 1) {
CurPage = i + 1; // Use the index in the array.
}
});
$(".CurrPageNumber").val(CurPage);
CurrentPageView = CurPage;

Issues with rotating jqueryUI modal

I am trying to build a modal that rotates to a particular element, $(.linkmoddet), based on a clicked element in the navbar $('.selectcircle') using the .switchClass function in jQueryUI.
However, I am having issues with the actual math involved, often causing:
only one or two elements to rotate at a time.
multiple elements gaining classes but not losing them.
occasionally losing all the classes involved, defaulting the element in question to a standard size and position in CSS.
Code
Edit: This has now been fixed.
http://codepen.io/yeasayer/pen/ZWxYZG
var selectcircle = $('.selectcircle');
var linkmoddet = $('.linkmoddet');
selectcircle.click(function(){
var circleindex = $(this).index()-1;
var centerindex;
console.log(circleindex);
selectcircle.each(function (index){
if (circleindex == index)
{
console.log($(this));
}
});
linkmoddet.each(function (index){
if ($(this).hasClass('moddetcenter'))
{
centerindex = $(this).index();
console.log("the center is index #"+centerindex);
}
var rotation = centerindex - circleindex;
//This is where I start having issues.
var i = $(this).index() + rotation;
var j;
if (i <= -1)
{
j = i + moddetids.length-1;
$(this).switchClass(classes[i+$(this).index()],classes[j]);
}
if (i >= moddetids.length)
{
j = i - moddetids.length;
$(this).switchClass(classes[i-$(this).index()],classes[j]);
}
else
{
if (rotation < 0)
{
j = i-1;
}
else
{
j = i+1;
}
$(this).switchClass(classes[i], classes[j]);
}
});
});
Does anyone have an idea on how to achieve the desired results, possibly in a simpler manner than described above?

Alright, it turns out that I figured it out by doing the following:
linkmoddet.each(function (index){
var classnum;
var newrot;
if ($(this).hasClass('moddetcenter'))
{
classnum = 2;
if (rotation < 0)
{
rotation += classes.length;
}
if (classnum + rotation >= classes.length)
{
newrot = classnum + rotation - classes.length;
$(this).switchClass(classes[classnum],classes[newrot]);
}
else if (rotation != 0)
{
$(this).switchClass(classes[classnum],classes[classnum+rotation]);
}
}
/* This is repeated for all the classes available in the classes array.
* ie: 0 being the first class, 1 being the second, etc. It's not an
* elegant solution, but it works for my current needs at the moment
* while I put it in a function in the future. */
Thanks!

mcustom Scrollbar autoscroll Issue

I am trying to create a div with content scrolling horizontally after a specific period of time - Like a slide show. I am using mcustomscollbar plugin. I am using a for loop to increment the id's and using the scrollTo function to slide the content but the scroll jumps to the last one.
Here its the js
for (var num = 1; num < 24; num++) {
var idj = '#' + 'id' + num;
var dlp = scrollToI(idj);
}
function scrollToI(person) {
setTimeout(function () {
console.log(person);
$('#content1').mCustomScrollbar("scrollTo", person);
}, 2000);
}
Fiddle : http://jsfiddle.net/infern00/3psLU/
ScrollBar Plugin used : http://manos.malihu.gr/jquery-custom-content-scroller/

You mean something like this:
$(document).ready(function () {
$("#content1").mCustomScrollbar({
axis: "x",
theme: "dark-thick",
advanced: {
autoExpandHorizontalScroll: true
}
});
var i = 1;
var interval = setInterval(function () {
var idj = '#' + 'id' + i;
console.log(idj);
scrollToI(idj);
if (i > 23) clearInterval(interval);
i++;
}, 2000);
function scrollToI(person) {
$('#content1').mCustomScrollbar("scrollTo", person);
}
});

Execute function IF another function is complete NOT when

I am having trouble creating a slider that pauses on hover, because I execute the animation function again on mouse off, if I flick the mouse over it rapidly (thereby calling the function multiple times) it starts to play up, I would like it so that the function is only called if the other function is complete, otherwise it does not call at all (to avoid queue build up and messy animations)
What's the easiest/best way to do this?
$(document).ready(function() {
//get variables
var slide_width = $('.slider_container').width();
var number_of_slides = $('.slider_container .slide').length;
var slider_width = slide_width*number_of_slides;
//set element dimensions
$('.slide').width(slide_width);
$('.slider').width(slider_width);
var n = 1;
$('.slider_container').hover(function() {
//Mouse on
n = 0;
$('.slider').stop(true, false);
}, function() {
//Mouse off
n = 1;
if (fnct == 0) sliderLoop();
});
//Called in Slide Loop
function animateSlider() {
$('.slider').delay(3000).animate({ marginLeft: -(slide_width * i) }, function() {
i++;
sliderLoop();
});
}
var i = 0;
var fnct = 0
//Called in Doc Load
function sliderLoop() {
fnct = 1
if(n == 1) {
if (i < number_of_slides) {
animateSlider();
}
else
{
i = 0;
sliderLoop();
}
}
fnct = 0
}
sliderLoop();
});
The slider works fine normally, but if I quickly move my mouse on and off it, then the slider starts jolting back and forth rapidly...been trying to come up with a solution for this for hours now..

Here's what fixed it, works a charm!
$(document).ready(function() {
//get variables
var slide_width = $('.slider_container').width();
var number_of_slides = $('.slider_container .slide').length;
var slider_width = slide_width*number_of_slides;
//set element dimensions
$('.slide').width(slide_width);
$('.slider').width(slider_width);
var n = 1;
var t = 0;
$('.slider_container').hover(function() {
clearInterval(t);
}, function() {
t = setInterval(sliderLoop,3000);
});
var marginSize = i = 1;
var fnctcmp = 0;
//Called in Doc Load
function sliderLoop() {
if (i < number_of_slides) {
marginSize = -(slide_width * i++);
}
else
{
marginSize = i = 1;
}
$('.slider').animate({ marginLeft: marginSize });
}
t = setInterval(sliderLoop,3000);
});

get interval ID from else statement when set in IF

I am attempting to create a responsive slider, that will change to a simple set of dot points when in mobile mode (< 940).
The issue I am facing is in my else statement I am unable to clearintervals that were made in the if statement, because t comes up as undefined. I have resorted to using
for (var i = 1; i < 99999; i++) window.clearInterval(i); to clear the interval which works, but I don't like it because it's ugly and cumbersome, is there another way of accomplishing this?
$(document).ready(function() {
function rePosition() {
//get responsive width
var container_width = $('.container').width();
//Slider for desktops only
if(container_width >= 940) {
//get variables
var slide_width = $('.slider_container').width();
var number_of_slides = $('.slider_container .slide').length;
var slider_width = slide_width*number_of_slides;
//set element dimensions
$('.slide').width(slide_width);
$('.slider').width(slider_width);
var n = 1;
var t = 0;
$('.slider_container').hover(function() {
clearInterval(t);
}, function() {
t = setInterval(sliderLoop,6000);
});
var marginSize = i = 1;
//Called in Doc Load
function sliderLoop(trans_speed) {
if (trans_speed) {
var trans_speed = trans_speed;
}
else
{
var trans_speed = 3000;
}
if (i < number_of_slides) {
marginSize = -(slide_width * i++);
}
else
{
marginSize = i = 1;
}
$('.slider').animate({ marginLeft: marginSize }, trans_speed);
}
t = setInterval(sliderLoop,6000);
$('.items li').hover(function() {
$('.slider').stop();
clearInterval(t);
var item_numb = $(this).index();
i = item_numb;
sliderLoop(500);
}, function() {
t = setInterval(sliderLoop,6000);
});
}
else
{
for (var i = 1; i < 99999; i++)
window.clearInterval(i);
$('.slider').stop(true, true);
$('.slider').css('margin-left', '0px');
//rearrange content
if($('.slider .slide .slide_title').length < 1) {
$('.items ul li').each(function() {
var item_numb = $(this).index();
var content = $(this).text();
$('.slider .slide:eq(' + item_numb + ')').prepend('<div class="title slide_title">' + content + '</div>')
});
}
}
}
rePosition();
$(window).resize(function() {
rePosition();
});
});

Teemu's comment is correct. I'll expand on it. Make an array available to all of the relevant code (just remember that globals are bad).
$(document).ready(function() {
var myIntervalArray = [];
Now, whenever you create an interval you will need to reference later, do this:
var t = setInterval();//etc
myIntervalArray.push(t); //or just put the interval directly in.
Then to clear them, just loop the array and clear each interval.
for (var i=0; i<myIntervalArray.length; i++)
clearInterval(myIntervalArray[i]);
}

Umm, wouldn't t only be defined when the if part ran... as far as I can tell, this is going to run and be done... the scope will be destroyed. If you need to maintain the scope across calls, you'll need to move your var statements outside of reposition(), like so:
$(document).ready(function() {
var t = 0;
...
function rePosition() { ... }
});
