How should I scroll my page on mobile devices?

I have a slider that scrolls when user uses scroll wheel, but on mobile phone it doesn't work. How i should solve this? I used jQuery scroll() but it is not working. Help please.
The slider is pretty much simple, and totaly fine on computer, but it is not working on my phone
What should i use? What method?
$(document).ready(function() {
var curPage = 1;
var numOfPages = $(".skw-page").length;
var animTime = 1000;
var scrolling = false;
var pgPrefix = ".skw-page-";
function pagination() {
scrolling = true;
$(pgPrefix + curPage).removeClass("inactive").addClass("active");
$(pgPrefix + (curPage - 1)).addClass("inactive");
$(pgPrefix + (curPage + 1)).removeClass("active");
setTimeout(function() {
scrolling = false;
}, animTime);
};
function navigateUp() {
if (curPage === 1) return;
curPage--;
pagination();
};
function navigateDown() {
if (curPage === numOfPages) return;
curPage++;
pagination();
};
$(document).on("mousewheel DOMMouseScroll", function(e) {
if (scrolling) return;
if (e.originalEvent.wheelDelta > 0 || e.originalEvent.detail < 0) {
navigateUp();
} else {
navigateDown();
}
});
$(document).on("keydown", function(e) {
if (scrolling) return;
if (e.which === 38) {
navigateUp();
} else if (e.which === 40) {
navigateDown();
}
});
});

Disable background scrolling when a modal is enabled

I am using a template with the following code to handle scrolling:
Here is the template.

if (delta > 50 && canScroll) {
canScroll = false;
clearTimeout(scrollController);
scrollController = setTimeout(function(){
canScroll = true;

How can I disable this code so the background doesn't scroll when an elements display is set to "block" meaning a modal is present?
Sorry for being vague if you need more specifics let me know!
EDIT 1:
I have tried disabled the div using:
$(".l-viewport").attr('disabled','disabled');
I have set the z-index of the model above all else

you can create a class HideScroll in your css:
.HideScroll {
overflow-y: hidden !important;
overflow-x: hidden !important;
}
The in the code that displays your modal, add this css to your main div:
$('.yourMainDivClass').addClass('HideScroll')
upon modal close, remove the class:
$('.yourMainDivClass').removeClass('HideScroll')
you can also use jquery toggleClass function.
OR
you can wrap your main div inside <fieldset> and set it's disabled attribute to true:
<fieldset id="fs-1">
<div id="yourMainDiv"></div>
</fieldset>
upon showing modal:
$('#fs-1').attr('disabled', true);
upon closing modal:
$('#fs-1').removeAttr('disabled');

Parallax scroll not working on mobile

Hi there I have a parallax effect scroll on my website, it is all working good on desktop but mobile device it is not working properly when I attempt to even scroll/swipe down the page.
Here is the javascript:
var ticking = false;
var isFirefox = /Firefox/i.test(navigator.userAgent);
var isIe = /MSIE/i.test(navigator.userAgent) || /Trident.*rv\:11\./i.test(navigator.userAgent);
var scrollSensitivitySetting = 30;
var slideDurationSetting = 800;
var currentSlideNumber = 0;
var totalSlideNumber = $('.background').length;
function parallaxScroll(evt) {
if (isFirefox) {
delta = evt.detail * -120;
} else if (isIe) {
delta = -evt.deltaY;
} else {
delta = evt.wheelDelta;
}
if (ticking != true) {
if (delta <= -scrollSensitivitySetting) {
ticking = true;
if (currentSlideNumber !== totalSlideNumber - 1) {
currentSlideNumber++;
nextItem();
}
slideDurationTimeout(slideDurationSetting);
}
if (delta >= scrollSensitivitySetting) {
ticking = true;
if (currentSlideNumber !== 0) {
currentSlideNumber--;
}
previousItem();
slideDurationTimeout(slideDurationSetting);
}
}
}
function slideDurationTimeout(slideDuration) {
setTimeout(function () {
ticking = false;
}, slideDuration);
}
var mousewheelEvent = isFirefox ? 'DOMMouseScroll' : 'wheel';
window.addEventListener(mousewheelEvent, _.throttle(parallaxScroll, 60), false);
function nextItem() {
var $previousSlide = $('.background').eq(currentSlideNumber - 1);
$previousSlide.css('transform', 'translate3d(0,-130vh,0)').find('.content-wrapper1').css('transform', 'translateY(40vh)');
currentSlideTransition();
}
function previousItem() {
var $previousSlide = $('.background').eq(currentSlideNumber + 1);
$previousSlide.css('transform', 'translate3d(0,30vh,0)').find('.content-wrapper1').css('transform', 'translateY(30vh)');
currentSlideTransition();
}
function currentSlideTransition() {
var $currentSlide = $('.background').eq(currentSlideNumber);
$currentSlide.css('transform', 'translate3d(0,-15vh,0)').find('.content-wrapper1').css('transform', 'translateY(15vh)');
;
}
Your help would be appreciated thank you!

Create a javascript object

I would say I am fairly decent with javascript and jQuery, well, enough to get the job done and done pretty well.
I do however lack a deep understanding of js.
I have created some functions for highlighting table elements.
ctrl+click toggles selections
shift+click+drag highlights selection
My question does not pertain to whether or not my implementation is the best way or not but ...
How do I abstract this functionality so I can add this functionality to any table. Like if I add more highlighting features and such and put this in its own .js file. How would I attach it to any html table?
Sorry if this has already been answered, but I could not think of what to search for.
Thank you.
****Newest Code****
This code is in its own .js file and is attached to my table.
All the current functionality is there. The only thing I am weary of is the .off() functions. In my case, I am reloading new tables.... as I type this, I realize I should just empty the tr's from the table instead of recreating a new table all the time, then I could get rid of the .off() calls.
$.fn.addEvents = function(obj)
{
console.log("Adding events to table");
var properties = $.extend(true,
{
shifting: false,
ctrling: false,
mousing: false,
mouseenter: 0,
mouseleave: 0,

tmptrajectory: null

}

}
}

you can wrap all this in a function since you have some local variables related to individual selection
$.fn.addEvents = function(obj) {
var properties = $.extend(true, {
shifting: false,
ctrling: false,
mousing: false,
mouseenter: 0,
mouseleave: 0,
trajectory: null
}, obj || {});
return $(this)
.off('click')
.off('contextmenu')
.on('click', function() {
.....
})
.on('mouseleave', function(e) {
//rename your local variables with `properties.` prefix
properties.mouseleave = e.clientY;
if (properties.shifting && properties.mousing) {
tmptrajectory = properties.mouseenter - properties.mouseleave < 0 ? 1 : -1;
}
if ($(this).hasClass('selected') && properties.shifting && properties.mousing && properties.trajectory != null && properties.trajectory != tmptrajectory) {
$(this).removeClass('selected');
$(this).find('td').removeClass('selected');
}
....
});
}
usage
$('#datatablebody tr').addEvents({ shifting: false, ctrling: true }); //custom settings
$('#someother tr').addEvents(); //default settings

you could add that functionality to a class and add that class to the tables you want to affect...
Here I create the class .myTableBeh and all tables with that class will have the behaviour you programmed.
var shifting = false;
var ctrling = false;
var mousing = false;
var mouseenter = 0;
var mouseleave = 0;
var trajectory = null;
$('.myTableBeh tr')
.off('click')
.off('contextmenu')
.on('click', function()
{
if(!ctrling)
{
$('.myTableBeh tr, .myTableBeh tr td').removeClass('selected');
$(this).addClass('selected');
$(this).find('td').addClass('selected');
}
else if(ctrling && $(this).hasClass('selected'))
{
$(this).removeClass('selected');
$(this).find('td').removeClass('selected');
}
else if(ctrling && !$(this).hasClass('selected'))
{
$(this).addClass('selected');
$(this).find('td').addClass('selected');
}
})
.on('contextmenu', function(ev)
{
ev.preventDefault();
$('.myTableBeh tr, .myTableBeh tr td').removeClass('selected');
$(this).addClass('selected');
$(this).find('td').addClass('selected');
showContextMenuTR($(this).closest('tr').attr('id'), ev.clientX, ev.clientY);
return false;
})
.off('mousedown')
.on('mousedown', function(e)
{
mousing = true;
multiselectrow($(this));
})
.off('mouseenter')
.on('mouseenter', function(e)
{
mouseenter = e.clientY;
multiselectrow($(this));
})
.off('mouseleave')
.on('mouseleave', function(e)
{
mouseleave = e.clientY;
if(shifting && mousing)
{
tmptrajectory = mouseenter - mouseleave < 0?1:-1;
}
if($(this).hasClass('selected') && shifting && mousing && trajectory != null && trajectory != tmptrajectory)
{
$(this).removeClass('selected');
$(this).find('td').removeClass('selected');
}
if(shifting && mousing && trajectory == null)
{
trajectory = tmptrajectory;
}
})
.off('mouseup')
.on('mouseup', function(e)
{
mousing = false;
trajectory = null;
multiselectrow($(this));
});

Thanks to the answer from #JAG I was able to create a nice add on to any HTML table that handles highlighting.
Check out the fiddle for the working version and please use it if you find it helpful or useful for your site.
You can even implement keys to move the tr position up or down in the table. I removed my implementation because it was specific to the project I am working on.
I made it so you have to mouse over the table in order to interact with it and mouse leave to un-focus it.
https://jsfiddle.net/kwj74kg0/2/
//Add the events simply by running this
$('#dtable tr').addEvents(0);
/**
* This add on can be applied and customized to any html tr set i.e. $('#tableid tr').addEvents()
* It will add highlighting capability to the table.
*
* Single click highlight tr
* Click -> Shift + click highlight/toggle range
* Shift+MouseDown+Drag highlight/toggle range
* Ctrl+Click toggle item

Set interval to make auto-slide functionality(Magento Site)

the below-following code is written by freelancer programmer for the silde banner for our Magento website. This is only for slide banner when the customer clicks the pager navigation menu; it slides to next banner. I want to set Interval for this so that It can automatically slide with clicking pager button. Thank you!!!
function initialize_banner_slider(banner_id) {
if ($(banner_id).size() <= 0) return;
var make_center = function(center) {
center.removeClass("on_right").removeClass("on_left").addClass("on_center");
$("body").removeClass("theme-light").removeClass("theme-dark").addClass("theme-"+center.data("theme"));
center.find(".fadeup").each(function() {
$(this).hide().css("top", (parseInt($(this).data("pos-y"))/750*100+100) + "%");
});
$(banner_id + " ul.banner_pager li").removeClass("active");
$($(banner_id + " ul.banner_pager li")[center.index()]).addClass("active");
setTimeout(function() {
center.find(".fadeup").each(function() {
$(this).show().animate({"top": "-=100%"});
/* $(this).css("top", parseInt($(this).data("pos-y"))); */
});
}, 600);
}

You would add something like this:
setInterval(function(){move_full_card_right(banner_id);},5000);
You should be able to throw that in you document ready as long as you can get the banner_id. I don't know how you are setting the banner id, so I can't help you with that.
