Random questions order when game starts - Trivia javascript game

I have a working code of a 10 text questions' trivia game with a timer (html, javascript, css).
How the questions can be served from a simple .txt file (so I can scale)?
How the javascript can choose the questions in a random order, every time the games starts?
I have studied 1 to get an idea. However, my javascript coding skills are very limited. I would appreciate if you can point me to the right direction.

In your case the best way would be to create an API (for example https://fastapi.tiangolo.com/) that would return a random question, but if you want to have it in a separate file you would simply have to move the variable questions to another javascript file and import it into the <head> of your web page.
To randomize the JSON you can use the following function:
function shuffleQuestions(questions) {
for (let i = questions.length - 1; i > 0; i--) {
const j = Math.floor(Math.random() * (i + 1));
[questions[i], questions[j]] = [questions[j], questions[i]];
}
}

Update an array with data from inputs

I have several inputs, which I am copying n times and I am trying to add numeric values from inputs in the array. I marked word "add" because an array may be already filled by other numbers.
I'm trying to apply method from UncleDave's answer here:
JavaScript - Add Value from input box to array
Example:
I have an array:
var exampleArray = [[1, 1.5], [1, 1], [0, 25.5]];
What I have done:
Wrote value 25 in first input. Wrote value 1.5 in the second input.
Create two new inputs.
Wrote value 25.4 in first input. Wrote value 1 in the second input.
Pressed button for adding into an array.
What I am trying to reach:
var exampleArray = [[1, 1.5], [1, 1], [0, 25.5], [25, 1.5], [25.4, 1]];
What I have reached:
"Udefined" in the console log.
Here Is jsfiddle link with my code: https://jsfiddle.net/aectann/k3qwoz0g/12/
updated with snippet (ok, it was not hard at this time, MTCoster, thank you for advice):

The getElementsByClassName() method returns a collection of all
elements in the document with the specified class name, as a NodeList
object.
You can iterate over the collections for all the numeric inputs and update your result. But I would suggest is to create another class for numeric inputs, so you wouldn't need to check for the type of the input and would keep your code generic.
You can try this code and feel free to clear your doubts in the comments.
function guardarNumeros() {
boxvalue = document.getElementsByClassName('myInput');
i = 0;
while (i < boxvalue.length) {
if (boxvalue[i].type == "number") {
if (boxvalue[i+1] && boxvalue[i+1].type == "number") {
tmp = [boxvalue[i].value, boxvalue[i+1].value]
tmpARR.push(tmp);
i+=2;
}
} else {
i++;
}
}
console.log(tmpARR);
return false;
}

The error is in "guardarNumeros" function because getElementsByClassName returns a collection and collection does not have a "value" property.
try this code
function guardarNumeros() {
const inputs = [...document.getElementsByClassName('myInput')];
const inputNumberArr = inputs.filter(x => x.type === 'number');
// tmpARR = [];
for (let i = 0; i < inputNumberArr.length; i++) {
const element = inputNumberArr[i];
if (i % 2 === 0) {
tmpARR.push([element.value]);
} else if (tmpARR[tmpARR.length -1] instanceof Array) {
tmpARR[tmpARR.length -1].push(element.value);
} else {
tmpARR.push([element.value]);
}
}
return false;
}

Can't seem to integrate my CSS and JS/Jquery files in my HTML

Pretty new to coding, was just wondering if maybe someone could revise why my .CSS & .JS files are not linking with my HTML?
Here are the lines & this is what it's supposed to look like: https://codepen.io/MatteoV/pen/aGqQBe
I will also be trying to implement this code into Webflow, would anyone know where I can implement these lines?

Jquery custom sorting issue

I have a page that loads photos on page load from an API.
** Edit: Here is a CodePen with the page, error happing there: http://codepen.io/nathan-anderson/pen/GqXbvK
When initially loading the page I use this to call on the info and use the lightgallery plugin:
// ----------------------------------------------------------------//
// ---------------// Unsplash Photos //---------------//
// ----------------------------------------------------------------//
function displayPhotos(data) {
var photoData = '';
$.each(data, function (i, photo) {
photoData += '<a class="tile"' + 'data-sub-html="#' + photo.id + '"'+ 'data-src="' + photo.urls.regular + '">' + '<img alt class="photo" src="' + photo.urls.regular + '">' + '<div class="caption-box" id="' + photo.id + '">' + '<h1 class="photo-title">' + 'Photo By: ' + photo.user.name + '</h1>' + '<p class="photo-description"> Description: Awesome photo by ' + photo.user.name + ' (aka:' + '<a target="_blank" href="' + photo.links.html + '">' + photo.user.username + ')</a>' + ' So far this photo has ' + '<span>' + photo.likes + '</span>' + ' Likes.' + ' You can download this photo if you wish, it has a free <a target="_blank" href="https://unsplash.com/license"> Do whatever you want </a> license. <a target="_blank" href="' + photo.links.download + '"><i class="fa fa-download" aria-hidden="true"></i> </a> </p>' + '</div>' + '</a>';
});
// Putitng into HTML
$('#photoBox').html(photoData);
//--------//
// Calling Lightbox
//--------//
$('#photoBox').lightGallery({
selector: '.tile',
download: false,
counter: false,
zoom: false,
thumbnail: false,
mode: 'lg-fade'
});
} // End Displayphotos function
// Show popular photos on pageload
$.getJSON(unsplashAPI, popularPhotos, displayPhotos);
I have multiple buttons for showing different orders of the photos. The API grabs different photos based on the "order_by" option.
This is my code to show the different sections:
var popularPhotos = {
order_by: "popular",
format: "json"
};
var latestPhotos = {
order_by: "latest",
format: "json"
};
var oldestPhotos = {
order_by: "oldest",
format: "json"
};
// Button Click Changes
$('button').click(function () {
$('button').removeClass("active");
$(this).addClass("active");
}); // End button
// Show Popular Photos
$('#popular').click(function () {
$.getJSON(unsplashAPI, popularPhotos, displayPhotos);
}); // End button
// Show latest Photos
$('#latest').click(function () {
$.getJSON(unsplashAPI, latestPhotos, displayPhotos);
}); // End button
// Show oldest Photos
$('#oldest').click(function () {
$.getJSON(unsplashAPI, oldestPhotos, displayPhotos);
}); // End button
This does load the new photos on button click but it breaks the function of the lightbox plugin.
Any thoughts? Anyone else running into this?
-- Thanks

So, the reason is a known issue with the library when attaching lightGallery without properly destroying previous listeners:
A soln in this case is a simple destroy before reinitialising it inside the displayPhotos function.
Just declare a variable gallery in outside scope like : var gallery;
then update the displayPhotos function reinit like:
//destroy if existing
if(gallery) gallery.data('lightGallery').destroy(true);

Format credit card number

How to format and validate a credit card number with spaces between each 4 digit while typing:
eg: 4464 6846 4354 3564
I have tried:
$('.creditno').keyup(function() {
cc = $(this).val().split("-").join("");
cc = cc.match(new RegExp('.{1,4}$|.{1,4}', 'g')).join("-");
$(this).val(cc);
});
Please help

Try this:
function cc_format(value) {
var v = value.replace(/\s+/g, '').replace(/[^0-9]/gi, '')
var matches = v.match(/\d{4,16}/g);
var match = matches && matches[0] || ''
var parts = []
for (i=0, len=match.length; i<len; i+=4) {
parts.push(match.substring(i, i+4))
}
if (parts.length) {
return parts.join(' ')
} else {
return value
}
}
Note: Check this for detailed information https://www.peterbe.com/plog/cc-formatter.
To restrict the user to enter number only:
Javascript Way
<input type="text" id="txt_cardNumber" name="txt_cardNumber" onkeypress="return checkDigit(event)">
function checkDigit(event) {
var code = (event.which) ? event.which : event.keyCode;
if ((code < 48 || code > 57) && (code > 31)) {
return false;
}
return true;
}
OR
function checkDigit() {
var allowedChars = "0123456789";
var entryVal = document.getElementById('txt_cardNumber').value();
var flag;
for(var i=0; i<entryVal.length; i++){
flag = false;
for(var j=0; j<allowedChars.length; j++){
if(entryVal.charAt(i) == allowedChars.charAt(j)) {
flag = true;
}
}
if(flag == false) {
entryVal = entryVal.replace(entryVal.charAt(i),""); i--;
}
}
return true;
}
HTML5 Way
<input type="text" id="txt_cardNumber" name="txt_cardNumber" pattern="[0-9.]+">
<input type="number" id="txt_cardNumber" name="txt_cardNumber">
jQuery Way
$("#txt_cardNumber").keypress(function (e) {
if ((e.which < 48 || e.which > 57) && (e.which !== 8) && (e.which !== 0)) {
return false;
}
return true;
});
Note: Please check here to get more information about various key code.

Just wrote this to handle Visa, Discover, Master Card and Amex (with formatting and card type identification).
// SAMPLE FIELD: <input type="text" name="cstCCNumber" id="cstCCNumber" value=""onkeyup="cc_format('cstCCNumber','cstCCardType');">
function cc_format(ccid,ctid) {
// supports Amex, Master Card, Visa, and Discover
// parameter 1 ccid= id of credit card number field
// parameter 2 ctid= id of credit card type field
var ccNumString=document.getElementById(ccid).value;
ccNumString=ccNumString.replace(/[^0-9]/g, '');
// mc, starts with - 51 to 55
// v, starts with - 4
// dsc, starts with 6011, 622126-622925, 644-649, 65
// amex, starts with 34 or 37
var typeCheck = ccNumString.substring(0, 2);
var cType='';
var block1='';
var block2='';
var block3='';
var block4='';
var formatted='';
if (typeCheck.length==2) {
typeCheck=parseInt(typeCheck);
if (typeCheck >= 40 && typeCheck <= 49) {
cType='Visa';
}
else if (typeCheck >= 51 && typeCheck <= 55) {
cType='Master Card';
}
else if ((typeCheck >= 60 && typeCheck <= 62) || (typeCheck == 64) || (typeCheck == 65)) {

}
else if (typeCheck==34 || typeCheck==37) {
cType='American Express';
}
else {
cType='Invalid';
}
}
// all support card types have a 4 digit firt block
block1 = ccNumString.substring(0, 4);
if (block1.length==4) {
block1=block1 + ' ';
}
if (cType == 'Visa' || cType == 'Master Card' || cType == 'Discover') {
// for 4X4 cards
block2 = ccNumString.substring(4, 8);
if (block2.length==4) {
block2=block2 + ' ';
}

}

I couldn't find a reasonable solution that works with text editing, so here you go:
$("#cardNumber").on("keydown", function(e) {
var cursor = this.selectionStart;
if (this.selectionEnd != cursor) return;
if (e.which == 46) {
if (this.value[cursor] == " ") this.selectionStart++;
} else if (e.which == 8) {
if (cursor && this.value[cursor - 1] == " ") this.selectionEnd--;
}
}).on("input", function() {
var value = this.value;
var cursor = this.selectionStart;
var matches = value.substring(0, cursor).match(/[^0-9]/g);
if (matches) cursor -= matches.length;
value = value.replace(/[^0-9]/g, "").substring(0, 16);
var formatted = "";
for (var i=0, n=value.length; i<n; i++) {
if (i && i % 4 == 0) {
if (formatted.length <= cursor) cursor++;
formatted += " ";
}
formatted += value[i];
}
if (formatted == this.value) return;
this.value = formatted;
this.selectionEnd = cursor;
});
The keydown listener is needed to adjust the cursor position for backspace and delete to move past spaces. It should not be used to restrict character entry, as you don't want to use key codes for that.
The input listener rebuilds the text, strips non-numbers, adds spaces every 4 characters, and preserves the cursor position.

With ES6
export const formatCardNumber = value => {
const regex = /^(\d{0,4})(\d{0,4})(\d{0,4})(\d{0,4})$/g
const onlyNumbers = value.replace(/[^\d]/g, '')
return onlyNumbers.replace(regex, (regex, $1, $2, $3, $4) =>
[$1, $2, $3, $4].filter(group => !!group).join(' ')
)
}

function cc_format(value) {
var v = value.replace(/\s+/g, '').replace(/[^0-9]/gi, '')
var matches = v.match(/\d{4,16}/g);
var match = matches && matches[0] || ''
var parts = []
for (i=0, len=match.length; i<len; i+=4) {
parts.push(match.substring(i, i+4))
}
if (parts.length) {
return parts.join(' ')
} else {
return value
}
}
onload = function() {
document.getElementById('cc').oninput = function() {
this.value = cc_format(this.value)
}
}
function checkDigit(event) {
var code = (event.which) ? event.which : event.keyCode;
if ((code < 48 || code > 57) && (code > 31)) {
return false;
}
return true;

Plunker for Formatting Credit Card Numbers
using angularjs directive. Format Card Numbers in xxxxxxxxxxxx3456 Fromat.
angular.module('myApp', [])
.directive('maskInput', function() {
return {
require: "ngModel",
restrict: "AE",
scope: {
ngModel: '=',
},
link: function(scope, elem, attrs) {
var orig = scope.ngModel;
var edited = orig;
scope.ngModel = edited.slice(4).replace(/\d/g, 'x') + edited.slice(-4);
elem.bind("blur", function() {
var temp;
orig = elem.val();
temp = elem.val();
elem.val(temp.slice(4).replace(/\d/g, 'x') + temp.slice(-4));
});
elem.bind("focus", function() {

});
}
};
})
.controller('myCtrl', ['$scope', '$interval', function($scope, $interval) {
$scope.creditCardNumber = "1234567890123456";
}]);

using vanilla js
javascript:
function formatCreditCardOnKey(event) {
//on keyup, check for backspace to skip processing
var code = (event.which) ? event.which : event.keyCode;
if(code != 8)
formatCreditCard();
else{
//trim whitespace from end; trimEnd() doesn't work in IE
document.getElementById("cardNumber").value = document.getElementById("cardNumber").value.replace(/\s+$/, '');
}
}
function formatCreditCard() {
var cardField = document.getElementById("cardNumber");
//remove all non-numeric characters
var realNumber = cardField.value.replace(/\D/g,'');
var newNumber = "";
for(var x = 1; x <= realNumber.length; x++){
//make sure input is a digit
if (isNumeric(realNumber.charAt(x-1)))
newNumber += realNumber.charAt(x-1);
//add space every 4 numeric digits
if(x % 4 == 0 && x > 0 && x < 15)
newNumber += " ";
}
cardField.value = newNumber;
}
function isNumeric(char){
return('0123456789'.indexOf(char) !== -1);
}
HTML:
<input type="text" id="cardNumber" maxlength="19" onKeyUp="formatCreditCardOnKey(event)" onBlur="formatCreditCard()" onFocus="formatCreditCard()"/>
This works (for me) with autofill, allows the user to use backspace as expected (they don't have to delete whitespace), and doesn't allow (other) non-numeric characters.

<?php
function luhn_check($number) {
// Strip any non-digits (useful for credit card numbers with spaces and hyphens)
$number=preg_replace('/\D/', '', $number);
// Set the string length and parity
$number_length=strlen($number);
$parity=$number_length % 2;
// Loop through each digit and do the maths
$total=0;
for ($i=0; $i<$number_length; $i++) {
$digit=$number[$i];
// Multiply alternate digits by two
if ($i % 2 == $parity) {
$digit*=2;
// If the sum is two digits, add them together (in effect)
if ($digit > 9) {
$digit-=9;
}
}
// Total up the digits
$total+=$digit;
}
// If the total mod 10 equals 0, the number is valid
return ($total % 10 == 0) ? TRUE : FALSE;
}
?>

function testCreditCard () {
myCardNo = document.getElementById('CardNumber').value;
myCardType = document.getElementById('CardType').value;
if (checkCreditCard (myCardNo,myCardType)) {
alert ("Credit card has a valid format")
}
else {alert (ccErrors[ccErrorNo])};
}

This may simple way:
function numberFormat(x){
return x.replace(/(.{4})/g, "$1 ");
}
If you want to connect dash every 4 digits,
function numberFormat(x){
return x.replace(/(.{4})/g, "$1-");
}

export const removeNonNumber = (string = "") => string.replace(/[^\d]/g, "");
export const removeLeadingSpaces = (string = "") => string.replace(/^\s+/g, "");
const limitLength = (string = "", maxLength) => string.substr(0, maxLength);
const FALLBACK_CARD = { gaps: [4, 8, 12], lengths: [16], code: { size: 3 } };
const addGaps = (string = "", gaps) => {
const offsets = [0].concat(gaps).concat([string.length]);
return offsets
.map((end, index) => {
if (index === 0) return "";
const start = offsets[index - 1];
return string.substr(start, end - start);
})
.filter((part) => part !== "")
.join(" ");
};
//this method to call
_formatNumber = (number, card) => {
const numberSanitized = removeNonNumber(number);
const maxLength = card.lengths[card.lengths.length - 1];
const lengthSanitized = limitLength(numberSanitized, maxLength);
const formatted = addGaps(lengthSanitized, card.gaps);
//set your state here
return formatted;
};
//use above method like this in text input
cardEnter(strings = "") {
this._formatNumber(strings, FALLBACK_CARD);
}

Let's try this. This code will replace your edit number in real-time.
$(document).ready(function() {
document.getElementById('card_no').onkeyup = function (e) {
if (this.value == this.lastValue) return;
var caretPosition = this.selectionStart;
var sanitizedValue = this.value.replace(/[^0-9]/gi, '');
var parts = [];
for (var i = 0, len = sanitizedValue.length; i < len; i += 4) {
parts.push(sanitizedValue.substring(i, i + 4));
}
for (var i = caretPosition - 1; i >= 0; i--) {
var c = this.value[i];
if (c < '0' || c > '9') {
caretPosition--;
}
}
caretPosition += Math.floor(caretPosition / 4);
this.value = this.lastValue = parts.join(' ');
this.selectionStart = this.selectionEnd = caretPosition;
}
});

This should work :
const handleKeyup=(value)=>{
//Remove whitespace
let newValue = value.split(" ").join("")
var format =newValue.split("").map((data, index) => {
if ((index + 1) % 4 == 0) {
data = data + " "
}
return data
})
format= format.join("")
console.log("format", format)}

This should work:
var format = [9, 2, 3,5,5,5,5,5,5,5,4, 5, 5, 5, 54, 4, 4, 4, 4, 4, 4,4,4, 4].map((data, index) => {
if ((index + 1) % 4 == 0) {
data = data + " "
}
return data
})
format= format.join("")
console.log("format", format)

This will do the job
$('#card-number').on('keypress change blur', function () {
$(this).val(function (index, value) {
var trimValue = value.trim();
var cardDivider = trimValue.replace(/ /g,'').length % 4;
if (trimValue.length < 19 && trimValue !== "") {
if (cardDivider === 0) {
return trimValue + " ";
}
}
return trimValue;
});
});

just learned js for 15 days, and encountered the same problem doing a project.
here is my absolutely rubbish solution, it's js only, don't know why even mention that since I don't know what jquery, etc means.
however, it works.
ps: feel free to judge.
const number = document.getElementById("card-number");
//get the new array every time there is
//an input in the field
let listened_number = [];
//put spaces in the array
function number_format(){
listened_number.splice(4,0," ");
listened_number.splice(9,0," ");
listened_number.splice(14,0," ");
}
//"input" type, the function gets activated every time something is entered or deleted.
number.addEventListener("input", e => {
//update the array
listened_number = number.value.replace(/\s+/g,"").split('');
// input caret position before any changes
// 'variable' represents the action to be
//applied on the caret later on
let caret_pos = number.selectionStart;
let variable = 0;
if(e.data === null){
variable = -1;
}else{
variable = 1;
}
// add spaces into the array.
number_format();
// reduced together but trimmed
number.value = listened_number.reduce((pv, cv) => pv + cv).trim();
//!!!!
//because the number.value(content in the input
//field) is reassigned, the input caret will appear
//at the very end, which is not user-friendly at all
//!!!!
switch(caret_pos){
case 5:
setSelection(5 + variable);
break;
case 10:
setSelection(10 + variable);
break;
case 15:
setSelection(15 + variable);
break;
default:
setSelection(caret_pos);
}
})
// set the caret where it supposes to be.
function setSelection(caretPos){
number.setSelectionRange(caretPos,caretPos);
number.focus();
}
<input maxlength="19" id="card-number" type="text" placeholder="e.g. 1234 5678 9123 0000">
it's messy... i know.

I found everything above never worked so I wrote a new one for fomatting to
0000 0000 0000 0000
//JS credit card formatter for onChange handler
"97181237removed12891237192random3712".replace(/[\D]/g, '').match(/.{1,4}/g)?.join(' ').substring(0, 19) || '';
// '9718 1237 1289 1237'

Format credit card number will be 16 digits and having automatic spacing between them will get by trying the below code for me.
try it once
handlecard(text) {
let formattedText = text.split(' ').join('');
if (formattedText.length <= 16) {
if (formattedText.length > 0) {
formattedText = formattedText.match(new RegExp('.{1,4}', 'g')).join(' ');
}
} else {
alert("plz stop here")
}
this.setState({ creditCard: formattedText });
return formattedText;
}
