js / css flip card game bug in shuffle function

I have created a js memory game. It has a 24-card grid, and it is supposed to shuffle randomly out of a deck of 15 cards in order to create a little variety. The game should be different every time. However, at random the game shuffles the initial deck and builds the board with 11 pairs and one non-pair of cards. Here's the whole js file:
`var score;
var cardsmatched;
var ui = $("#gameUI");
var uiIntro =$("#gameIntro");
var uiStats = $("# gameStats");
var uiComplete = $("#gameComplete");
var uiCards = $("#cards");
var uiScore = $(".gameScore");
var uiReset = $(".gameReset");
var uiPlay = $("#gamePlay");
var uiTimer = $("#timer");
var matchingGame = {};
matchingGame.deck = ['grilledfish', 'grilledfish','barbacoa', 'barbacoa','tripa', 'tripa','bajafish', 'bajafish','carneasada', 'carneasada','carnitas', 'carnitas', 'chorizoasado','chorizoasado','shrimptaco','shrimptaco','decabeza','decabeza','alpastor', 'alpastor','dorados','dorados', 'lengua','lengua','chicharron','chicharron','sudados','sudados', 'polloasado','polloasado',];
$(function(){

How to run a function in jQuery for 15 times

I have a jQuery function
setInterval(function () {
secondPlay()
}, 1000);
setInterval(function () {
secondPlay1()
}, 1000);
function secondPlay() {
$("body").removeClass("play");
var aa = $("ul.secondPlay li.active");
var ii = $('ul.secondPlay li:last-child').val();
if (aa.html() == undefined) {
aa = $("ul.secondPlay li").eq(0);
aa.addClass("before")
.removeClass("active")
.next("li")
.addClass("active")
.closest("body")
.addClass("play");
}
if (aa.is(":last-child")) {
$("ul.secondPlay li").removeClass("before");
aa.addClass("before").removeClass("active");
aa = $("ul.secondPlay li").eq(0);
aa.addClass("active")
.closest("body")
.addClass("play");
}
else {
$("ul.secondPlay li").removeClass("before");
aa.addClass("before")
.removeClass("active")
.next("li")
.addClass("active")
.closest("body")
.addClass("play");
}
}
I want to run this function for 15 times. How can I run it ?

Declare a variable as a counter. Increment that variable eachtime you calling the function. If the variable reaches 15, the stop the setInterval() by using clearInterval() function
var counter = 1;
var interval = setInterval(function () {
if (counter == 15) {
clearInterval(interval);
}
secondPlay()
counter++;
}, 1000);

You can use following code as reference.
(function(){
var count = 0;
var interval = setInterval(function(){
if(count>15){
window.crearInterval(interval);
}
else{
document.getElementById("lblCount").innerHTML = count;
count++;
}
},1000);
})()
<p id="lblCount"></p>

Try This
var timePlyed = 0;
function secondPlay() {
timePlyed++;
console.log(timePlyed);
if (timePlyed != 15) {
secondPlay();
}
}
secondPlay();

Enclose them in a for loop?
for (i = 0; i < 15; i++) {
...
}

you can use timeout function:
function secondPlay(i){
console.log(i);
}
function test(){
for(var i = 0; i < 15; i++){
setTimeout(function(){
secondPlay(i);
}, i * 1000);
}
}
call test() to execute the function.

Instead of setInterval, you could use a timeout:
var i = 0;
function secondPlay1() {
// do function
setTimeout(function() {
if (i < 15) {
i++;
secondPlay1();
}
}, 1000);
}

how to clear Interval on Mouse Over in java script?

Updating interval dynamically - jQuery or Javascript

I have two "stopwatches" in my code (and I may be adding more). This is the code I currently use below - and it works fine. But I'd really like to put the bulk of that code into a function so I'm not repeating the same code over and over.
When I tried doing it though, I could get it working - I think it was because I was passing stopwatchTimerId and stopwatch2TimerId into the function and it may have been passing by reference?
How can I reduce the amount of code repetition here?
var stopwatchTimerId = 0;
var stopwatch2TimerId = 0;
$('#stopwatch').click(function () {
if ($(this).hasClass('active')) {
$(this).removeClass('active');
clearInterval(stopwatchTimerId);
}
else {
$(this).addClass('active');
stopwatchTimerId = setInterval(function () {
var currentValue = parseInt($('#stopwatch-seconds').val()) || 0;
$('#stopwatch-seconds').val(currentValue + 1).change();
}, 1000);
}
});
$('#stopwatch2').click(function () {
if ($(this).hasClass('active')) {
$(this).removeClass('active');
clearInterval(stopwatch2TimerId);
}
else {
$(this).addClass('active');
stopwatch2TimerId = setInterval(function () {
var currentValue = parseInt($('#stopwatch2-seconds').val()) || 0;
$('#stopwatch2-seconds').val(currentValue + 1).change();
}, 1000);
}
});
As you can see, it's basically the same code in each except for stopwatchTimerId and $('#stopwatch-seconds') (and the same vars with 2 on it for the other one).

This won't pollute global scope and also you don't need to do any if-else statements. Just add data-selector to your new elements :)
<input id="stopwatch" type="text" data-selector="#stopwatch-seconds"/>
<input id="stopwatch2" type"text" data-selector="#stopwatch2-seconds"/>
$('#stopwatch stopwatch2').click(function () {
var $element = $(this),
interval = $element.data('interval');
selector = $element.data('selector');;
if ($element.hasClass('active')) {
$element.removeClass('active');
if (interval) {
clearInterval(interval);
}
}
else {
$element.addClass('active');
$element.data('interval', setInterval(function () {
var currentValue = parseInt($(selector).val()) || 0;
$(selector).val(currentValue + 1).change();
}, 1000));
}
});

function stopwatch(id){
$('#' + id).click(function () {
if ($(this).hasClass('active')) {
$(this).removeClass('active');
clearInterval(window[id]);
}
else {
$(this).addClass('active');
window[id] = setInterval(function () {
var currentValue = parseInt($('#' + id + '-seconds').val()) || 0;
$('#' + id + '-seconds').val(currentValue + 1).change();
}, 1000);
}
});
}
$(function(){
stopwatch("stopwatch");
stopwatch("stopwatch2");
});

You could do something like this (code is not very nice, you can improve it):
var stopwatchTimerId;
$('#stopwatch').click(function () {
doStopWatch(1);
});
$('#stopwatch2').click(function () {
doStopWatch(2);
});
var doStopWatch = function(option){
var stopWatch = option===1?$('#stopwatch'):$('#stopwatch2');
if (stopWatch.hasClass('active')) {
stopWatch.removeClass('active');
clearInterval(stopwatchTimerId);
}
else {
stopWatch.addClass('active');
stopwatchTimerId = setInterval(function () {
var currentValue = option===1?(parseInt($('#stopwatch-seconds').val()) || 0):(parseInt($('#stopwatch2-seconds').val()) || 0);
if(option===1)
$('#stopwatch-seconds').val(currentValue + 1).change();
else
$('#stopwatch2-seconds').val(currentValue + 1).change();
}, 1000);
}
}

Try
var arr = $.map($("div[id^=stopwatch]"), function(el, index) {
el.onclick = watch;
return 0
});
function watch(e) {
var id = this.id;
var n = Number(id.split(/-/)[1]);
if ($(this).hasClass("active")) {
$(this).removeClass("active");
clearInterval(arr[n]);
} else {
$(this).addClass("active");
arr[n] = setInterval(function() {
var currentValue = parseInt($("#" + id + "-seconds").val()) || 0;
$("#" + id + "-seconds").val(currentValue + 1).change();
}, 1000);
}
};
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js">
</script>
<div id="stopwatch-0">stopwatch1</div>
<input type="text" id="stopwatch-0-seconds" />
<div id="stopwatch-1">stopwatch2</div>
<input type="text" id="stopwatch-1-seconds" />

Select value inside object

How can I get the second value from videoid:uoSDF234and make it countdown ?
first I need "videoid":"uoSDF234" be the first countdown then next will be "videoid":"0apq3ss" and so on (if I add more data).
when I click the stop button, label id="vstopresult" will show the stopped videoid and second.
the countdown will looping for each videoid in videolist.
var videoinfo = [{"startdatetime":"2014-12-21 00:23:14","totalsecondrun":"2019402310","videolist":
[{"videoid":"uoSDF234","second":"10"},{"videoid":"0apq3ss","second":"14"}]}];
// JavaScript Document
var calduration = function(){
$.each(videoinfo, function(i, obj) {
$("#vstart").append(obj.startdatetime);
$("#vtotoals").append(obj.totalsecondrun);
$("#vid").append(videoinfo[0].videolist[0].videoid);
$("#vlefts").append(videoinfo[0].videolist[0].second);
var output = $("#vlefts");
var isPaused = false;
var time = videoinfo[0].videolist[0].second;
var t = window.setInterval(function() {
if(!isPaused) {
time--;
output.text(time);
}
if (time == 0){
clearInterval(t);
}
}, 1000);
//with jquery
$("#vpause").on('click', function(e) {
e.preventDefault();
isPaused = true;
});
$("#vplay").on('click', function(e) {
e.preventDefault();
isPaused = false;
});
$("#vstop").on('click', function(e) {
clearInterval(t);
$("#vstopresult").append(time);
});
});
};
calduration();
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<div>
<label id="vstart"></label><br>
<label id="vtotoals"></label><br>
<label id="vid"></label><br>
<label id="vlefts"></label><br>
<input type="button" value="play" id="vplay"/>
<input type="button" value="pause" id="vpause"/>
<input type="button" value="stop" id="vstop"/><br>
<label id="vstopresult"></label>
</div>

One crude possibility is to use setInterval, an example may be.
var videoinfo = [{
"startdatetime": "2014-12-21 00:23:14",
"totalsecondrun": "2019402310",
"videolist": [{
"videoid": "uoSDF234",
"second": "10"
}, {
"videoid": "0apq3ss",
"second": "14"
}]
}],
index = 0,
timerEl = document.getElementById('timer'),
countDown = 0,
intervalId;
function startCountdown() {
if (index < videoinfo[0].videolist.length) {
countDown = videoinfo[0].videolist[index].second;
intervalId = setInterval(function () {
timerEl.textContent = countDown;
if (countDown < 1) {
clearInterval(intervalId);
index += 1;
setTimeout(function () {
startCountdown();
}, 1000);
} else {
countDown -= 1;
}
}, 1000);
}
}
startCountdown();
<div id='timer'></div>
