Getting javascript - Uncaught TypeError: Issue - javascript

I am using numscroller.js for a counter but I'm getting two javascript errors:
Uncaught TypeError: Cannot read property 'top' of undefined at HTMLHeadingElement. - Line no - 40.
Can anyone help me please with the below code. It's showing the error is in the line number 40. Any help would be appreciated. Thank you in advance.

I think you forgot to return your jquery element in your plugin functions
$.fn.scrollzipInit = function() {
return $('body').prepend("<div style='position:fixed;top:0px;left:0px;width:0;height:0;' id='scrollzipPoint'></div>");
};
And
$.fn.rollerInit = function() {
var i = 0;
return $('.numscroller').each(function() {
i++;
$(this).attr('data-slno', i);
$(this).addClass("roller-title-number-" + i);
});
};

How could I add the following to my mediawiki main page?

I would like to add this timeline gimmick https://codepen.io/alvarotrigo/pen/yLzBJaN to the main page in my medawiki. How might I go about importing it? I have a script that enables HTML, but I do not know how to enable the CSS or JS.
I am not really a programmer and just trying to figure out the best way to test this out.
here is the code:
`
(function ($) {
$(function () {
$(window).on('scroll', function () {
fnOnScroll();
});
$(window).on('resize', function () {
fnOnResize();
});
var agTimeline = $('.js-timeline'),
agTimelineLine = $('.js-timeline_line'),
agTimelineLineProgress = $('.js-timeline_line-progress'),
agTimelinePoint = $('.js-timeline-card_point-box'),
agTimelineItem = $('.js-timeline_item'),
agOuterHeight = $(window).outerHeight(),
agHeight = $(window).height(),
f = -1,
agFlag = false;
function fnOnScroll() {
agPosY = $(window).scrollTop();
fnUpdateFrame();
}
function fnOnResize() {
agPosY = $(window).scrollTop();
agHeight = $(window).height();

I'm relatively new to programming. I took a class in high school, which was very mediocre. I'm now taking some starter courses in college, and my assignment is to improve a generic space game (which I have already started doing). I have a div for the timer, but for some reason, I can't get any functions to increase the _time variable. It's almost as though they're not allowed to access it. I have a function called "runTimer", which is supposed to increase "_time" by one every time it is run. I have another function called "increaseTime", which is supposed to run "runTimer" every 1000 milliseconds. The variable never seems to increase though. This hasn't been my first spaghetti code implementation of a timer, since I've tried various things over the past few hours. I just can't understand why the variable won't increase.
This is a big hunk of code. As RobG pointed out, try to work on paring back your question to the minimal, complete, and verifiable example you can.
That said, at a glance, it would appear that your timer probably is updating. At least _time is.
The problem is likely you are never re-drawing your div, so it isn't showing the updated value. You need to call game.displayTimer() every time _time updates.
Probably the easiest place to add it would be in your setInterval() in increaseTime():
my.increaseTime = function () {
setInterval(function(){
runTimer();
my.displayTime();
}, 1000)
}

Sometimes white background goes transparent on whole page

I wanted to use this kind of Photo Collage on my Website: Seamless Photo Collage by AutomaticImageMontage
so I downloaded it and pasted the code to my Website..
it works but sometimes when the page loads the white background goes transparent on the whole page transperent background
I'm using Parallax and Bootstrap, sometimes the parallax isn't working properly too.
I have tried to set the background to white in CSS but nothing.. sometimes it loads normally but sometimes goes transparent,
I have checked the console too but it showes only

AngularJS $watch within directive not triggering

I have a watch looking at my sliders model and when I want to set one of the properties to visible or enabled it doesn't seem to want to fire the watch changed event. If I click the button it should hide or disable the handle and it does not. If I drag another handle the updateDOM is called and the handle is then hidden or disabled. Not sure what I am doing incorrectly here.
scope.$watch('sliders', function(oldValue, newValue) {
console.log('sliders Update: ', oldValue, ' : ', newValue);
updateDOM();
});

jQuery Error on Plugin?

On my site my browser crashes when viewing a web page, It says its my script on line 21 only Im unsure whats wrong? Can anybody see a problem?
jQuery.fn.carousel = function(previous, next, options){
var sliderList = jQuery(this).children()[0];
if (sliderList) {
var increment = jQuery(sliderList).children().outerWidth("true"),
elmnts = jQuery(sliderList).children(),
numElmts = elmnts.length,
sizeFirstElmnt = increment,
shownInViewport = Math.round(jQuery(this).width() / sizeFirstElmnt),
firstElementOnViewPort = 1,
isAnimating = false;
for (i = 0; i < shownInViewport; i++) {
jQuery(sliderList).css('width',(numElmts+shownInViewport)*increment + increment + "px");
jQuery(sliderList).append(jQuery(elmnts[i]).clone());
}
jQuery(previous).click(function(event){
if (!isAnimating) {
if (firstElementOnViewPort == 1) {
jQuery(sliderList).css('left', "-" + numElmts * sizeFirstElmnt + "px");
firstElementOnViewPort = numElmts;
}
else {
firstElementOnViewPort--;
}
jQuery(sliderList).animate({
left: "+=" + increment,
y: 0,
queue: true
}, "swing", function(){isAnimating = false;});
isAnimating = true;
}
});
jQuery(next).click(function(event){
if (!isAnimating) {
if (firstElementOnViewPort > numElmts) {
firstElementOnViewPort = 2;
jQuery(sliderList).css('left', "0px");
}
else {
firstElementOnViewPort++;
}
jQuery(sliderList).animate({
left: "-=" + increment,
y: 0,
queue: true
}, "swing", function(){isAnimating = false;});
isAnimating = true;
}
});
}
};
Line 21 is
jQuery(sliderList).append(jQuery(elmnts[i]).clone());
I call my plugin with...
$('.viewer').each(function() {
$(this).carousel('.viewer .simplePrevious', '.viewer .simpleNext');
});
Is it on an HTML5 element and in IE?
I have had a similar problem, even with html5shiv. had to revert to xhtml for it to work again.
