How to create a navigation system in Javascript pagination pagify()

I have a js pagination system that find .classname elems and paginate them on-the-fly. Clicking on navigation pages the script shows only .classname elements in that interval.
When too much items have to be paginated I would like to add an arrow system to let navigate pages links. The main script is here: https://jsfiddle.net/gyzo2u9c/
(function($) {
var pagify = {
items: {},
container: null,
totalPages: 1,
perPage: 3,
currentPage: 0,
createNavigation: function() {
this.totalPages = Math.ceil(this.items.length / this.perPage);
$('.pagination', this.container.parent()).remove();
var pagination = $('<div class="pagination"></div>').append('<a class="nav prev disabled" data-next="false"><i class="fas fa-caret-left"></i></a>');
for (var i = 0; i < this.totalPages; i++) {
var pageElClass = "page";
if (!i)
pageElClass = "page current";
var pageEl = '<a class="' + pageElClass + '" data-page="' + (
i + 1) + '">' + (
i + 1) + "</a>";
pagination.append(pageEl);
}
pagination.append('<a class="nav next" data-next="true"><i class="fas fa-caret-right"></i></a>');
/*aggiungiamo la paginazione sopra nel calendario*/
if ($(this.container).selector == '#calendario .archivio') {
this.container.before(pagination);
} else {
/*sotto, in tutti gli altri casi*/
this.container.after(pagination);
}
var that = this;
$("body").off("click", ".nav");
this.navigator = $("body").on("click", ".nav", function() {
var el = $(this);
that.navigate(el.data("next"));
});
$("body").off("click", ".page");
this.pageNavigator = $("body").on("click", ".page", function() {
var el = $(this);
that.goToPage(el.data("page"));
$([document.documentElement, document.body]).animate({
scrollTop: ($(".archivio").offset().top - 120)
}, 1);
});
},
navigate: function(next) {
// default perPage to 5
if (isNaN(next) || next === undefined) {
next = true;
}
$(".pagination .nav").removeClass("disabled");
if (next) {
this.currentPage++;
if (this.currentPage > (this.totalPages - 1))
this.currentPage = (this.totalPages - 1);
if (this.currentPage == (this.totalPages - 1))
$(".pagination .nav.next").addClass("disabled");
} else {
this.currentPage--;
if (this.currentPage < 0)
this.currentPage = 0;
if (this.currentPage == 0)

}
this.showItems();
},

if (this.currentPage == (this.totalPages - 1))

if (this.currentPage == 0)
$(".pagination .nav.prev").addClass("disabled");
this.showItems();
},
showItems: function() {
this.items.hide().removeClass('item_visibile');
var base = this.perPage * this.currentPage;
this.items.slice(base, base + this.perPage).show().addClass('item_visibile');
this.updateNavigation();
},
init: function(container, items, perPage, currentPage) {
// default perPage to 5
if (isNaN(currentPage) || currentPage === undefined) {
currentPage = 0;
}
this.container = container;
this.currentPage = currentPage;
this.totalPages = 1;
this.perPage = perPage;
this.items = items;
this.createNavigation();
this.showItems();
}
};
// stuff it all into a jQuery method!
$.fn.pagify = function(perPage, itemSelector, currentPage) {
var el = $(this);
var items = $(itemSelector, el);
// default perPage to 5
if (isNaN(perPage) || perPage === undefined) {

}
// don't fire if fewer items than perPage
if (items.length <= perPage) {
return true;
}
pagify.init(el, items, perPage, currentPage);
};

jQuery(".archive").pagify(2, ".item");

Made a game for a website using javascript that asks multiplication questions but having trouble adapting this to perform addition questions

This is my multiplication game made using javascript which asks the user to answer questions and provides feedback. the game currently performs multiplication questions and I want it to ask the user addition questions without changing the parameters of the game. I want the game to display the same and function exactly like my multiplication game except it performs addition instead of multiplication using random numbers.

Change this line
this.CorrectAnswer = this.FirstNumber * this.SecondNumber;
to this
this.CorrectAnswer = this.FirstNumber + this.SecondNumber;
and probably change this
this.WrongAnswer = this.GenerateRandomNumber(9) * this.GenerateRandomNumber(9);
to this
this.WrongAnswer = this.GenerateRandomNumber(9) + this.GenerateRandomNumber(9);

You could use a computed property.
computed: {
//however you want to call it
style() {
return {transform : 'translate3d(' + this.translateX + 'px, 0, 0)'}
}
}
To use it just change your binding to :style="this.style"

Shift an array and rendering it in a html list

Using the following script I am not able to swift and set the focus for an array back in the list when clicking PREV.

How do I get rid of this JS error: TypeError: $(...).validate is not a function

I am using the following JS code from the fiddle provided in the answer here:
How to display messages from jQuery Validate plugin inside of Tooltipster tooltips?
Here's the fiddle: http://jsfiddle.net/kyK4G/
The error shows up on line 36, which is: submitHandler: function (form) { // for demo
And this is the error:
TypeError: $(...).validate is not a function
submitHandler: function (form) { // for demo
Code:
<script src="http://code.jquery.com/jquery-1.10.1.min.js"></script>
$(document).ready(function () {
// initialize tooltipster on text input elements
$('#myform input[type="text"]').tooltipster({
trigger: 'custom',
onlyOne: false,
position: 'right'
});
// initialize validate plugin on the form
$('#myform').validate({
errorPlacement: function (error, element) {
$(element).tooltipster('update', $(error).text());
$(element).tooltipster('show');
},
success: function (label, element) {
$(element).tooltipster('hide');
},
rules: {
field1: {
required: true,
email: true
},
field2: {
required: true,
minlength: 5
}
},
submitHandler: function (form) { // for demo
alert('valid form');
return false;
}
});
});

It sounds like you don't have the validate plugin script on the page:
http://ajax.aspnetcdn.com/ajax/jquery.validate/1.11.1/jquery.validate.min.js

It looks like you are not including the jQuery plugin that provides the .validate() method. You should include it after jQuery:
<script src="//ajax.aspnetcdn.com/ajax/jquery.validate/1.11.1/jquery.validate.min.js"><script>
Generally, if you have an object, you can try and access different attributes using dot notation as follows:
var myAwesomeObject = {
coolProperty: "whooooa!"
, coolMethod: function() {return this;}
};
myAwesomeObject.coolProperty; // "whooooa!"
myAwesomeObject.coolMethod; // function(){return this;}
If the property happens to be a method, you can call it like:
myAwesomeObject.coolMethod(); // Object {coolProperty: ...
If the property you are trying to access doesn't exist on the object, you will get back undefined
myAwesomeObject.missingProperty; // undefined
Since undefined is not a function, trying to call a missing property as a method will result in the error you saw:
myAwesomeObject.missingMethod(); // TypeError: you messed up.

I also got this problem. I have fixed this problem other way. That I got in the documentation
To fix the problem you have to declared a specific class.
Using the
mfp-TYPE CSS class (where TYPE is the desired content type). For example: <a class="mfp-image image-link">Open image</a>, $('.image-link').magnificPopup().
Another Example: <a class="mfp-iframe video-link">Open Video</a>, $('.video-link').magnificPopup().
