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(){

});
function init() {

uiPlay.click(function(e){
e.preventDefault();

startGame();
});
uiReset.click(function(e){

uiCards.children().each(function(index) {
$(this).css({
"left" : ($(this).width() + 20) * (index % 6),
"top" : ($(this).height() + 20) * Math.floor(index / 6)
});
var pattern = matchingGame.deck.pop();
$(this).find(".back").addClass(pattern);
$(this).attr("data-pattern",pattern);

Javascript Text Slideshow

I am trying to add text into a div using JavaScript and/or jQuery and then have that text change to different text every 10 seconds -- so somewhat like a slideshow of just plain text. Here's my code:
<div id="textslide"><p></p></div>
<script>
var quotes = new Array();
quotes[0] = "quote1";
quotes[1] = "quote2";
quotes[2] = "quote3";
quotes[3] = "quote4";
quotes[4] = "quote5";
var counter = 0;
while (true) {
if (counter > 4) counter = 0;
document.getElementById('textslide').firstChild.innerHTML = quotes[counter];
counter++;
setTimeout( // not sure what to put here, 500); // Want to delay loop iteration
}
</script>

HTML:
<div id="textslide"><p></p></div>
JavaScript/jQuery:
var quotes = [
"quote1",
"quote2",
"quote3",
"quote4",
"quote5",
];
var i = 0;
setInterval(function() {
$("#textslide").html(quotes[i]);
if (i == quotes.length) {
i = 0;
}
else {
i++;
}
}, 10 * 1000);
Working demo here

Use a function and call it on body onload
<html>
<head>
<script>
var counter = 0;
function changeText()
{
var quotes = new Array();
quotes[0] = "quote1";
quotes[1] = "quote2";
quotes[2] = "quote3";
quotes[3] = "quote4";
quotes[4] = "quote5";
if (counter > 4)
{
counter = 0;
}
document.getElementById("textslide").innerHTML = quotes[counter];
setTimeout(function(){changeText()},10000);
counter ++;
}
</script>
</head>
<body onload="changeText();">
<p id="textslide"></p>
</body>
</html>

Here is a suggestion with plain JS
function loop() {
if (counter > 4) counter = 0;
document.getElementById('textslide').firstElementChild.innerHTML = quotes[counter];
counter++;
setTimeout(loop, 500);
}
loop();
Demo here
If you want to use jQuery you can use this: $('#textslide p:first').text(quotes[counter]);
Demo here

Instead of while, use:
setInterval(function () {
//do your work here
}, 10000);

How to dynamically add elements via jQuery

The script below creates a slider widget the takes a definition list and turns it into a slide deck. Each dt element is rotated via css to become the "spine", which is used to reveal that dt's sibling dd element.
What I'm trying to do is to enhance it so that I can have the option to remove the spines from the layout and just use forward and back buttons on either side of the slide deck. To do that, I set the dt's to display:none via CSS and use the code under the "Remove spine layout" comment to test for visible.
This works fine to remove the spines, now I need to dynamically create 2 absolutely positioned divs to hold the left and right arrow images, as well as attach a click handler to them.
My first problem is that my attempt to create the divs is not working.
Any help much appreciated.

Creating elements in jQuery is easy:
$newDiv = $('<div />');
$newDiv.css({
'position': 'absolute',
'top': '10px',
'left': '10px'
});
$newDiv.on('click', function() {
alert('You have clicked me');
});
$('#your_container').append($newDiv);

function is undefined in firefox only

ok, the following code works ok in IE7+ and Chrome.
but for some reason, xfade is undefined in firefox
<html>
<body>
<div id="slider"></div>
<script type="text/javascript">
var Klimateka = {
Slider: function () {
// Check if we have a slider div on page
var slider = document.getElementById('slider');
if (slider != null) {
var images = ["slide-image-1.jpg", "slide-image-2.jpg", "slide-image-3.jpg", "slide-image-4.jpg"];
var i = images.length;
while (i) {
i -= 1;
var img = document.createElement("img");
img.src = "images/" + images[i];
slider.appendChild(img);
}
var d = document, imgs = new Array(), zInterval = null, current = 0, pause = false;
imgs = d.getElementById("slider").getElementsByTagName("img");
for (i = 1; i < imgs.length; i++) imgs[i].xOpacity = 0;
imgs[0].style.display = "block";
imgs[0].xOpacity = .99;
setTimeout("xfade()", 3500);
function xfade() {
cOpacity = imgs[current].xOpacity;
nIndex = imgs[current + 1] ? current + 1 : 0;
nOpacity = imgs[nIndex].xOpacity;
cOpacity -= .05;
nOpacity += .05;
imgs[nIndex].style.display = "block";
imgs[current].xOpacity = cOpacity;
imgs[nIndex].xOpacity = nOpacity;
setOpacity(imgs[current]);
setOpacity(imgs[nIndex]);
if (cOpacity <= 0) {
imgs[current].style.display = "none";
current = nIndex;
setTimeout(xfade, 3500);
} else {
setTimeout(xfade, 50);
}
function setOpacity(obj) {
if (obj.xOpacity > .99) {
obj.xOpacity = .99;
return;
}
obj.style.opacity = obj.xOpacity;
obj.style.MozOpacity = obj.xOpacity;
obj.style.filter = "alpha(opacity=" + (obj.xOpacity * 100) + ")";
}
}
}
},
bar: function () {
}
};
Klimateka.Slider();
i have setup a jsfiddler for testing:
http://jsfiddle.net/rTtKh/10/

This might only apply to Firefox:
functions do not hoist when declared inside a child block.
You declare xfade inside the if block, but you are calling it prior to the declaration:
setTimeout(xfade, 3500);
Put the function declaration on top.
You have to do the same with setOpacity inside xfade. <- That is not necessary.

Fix your line that says this: setTimeout("xfade()", 3500); to match your others:
setTimeout(xfade, 3500);

Use setTimeout(xfade, 3500) instead.

javascript countdown with showing milliseconds

I want to do a count down and want to show like format as Minutes:Seconds:Milliseconds. I made a count down with jquery plug-in countdown but it shows just Minutes:Seconds format.
Is there any way to make it right?
Many Thanks!

Hi guys I have developed a code for my self use the following code
counter for 20 seconds
var _STOP =0;
var value=1999;
function settimer()
{
var svalue = value.toString();
if(svalue.length == 3)
svalue = '0'+svalue;
else if(svalue.length == 2)
svalue = '00'+svalue;
else if(svalue.length == 1)
svalue = '000'+svalue;
else if(value == 0)
svalue = '0000';
document.getElementById('cn1').innerHTML = svalue[0];
document.getElementById('cn2').innerHTML = svalue[1];
document.getElementById('cn3').innerHTML = svalue[2];
document.getElementById('cn4').innerHTML = svalue[3];
value--;
if (_STOP==0 && value>=0) setTimeout("settimer();", 10);
}
setTimeout("settimer()", 10);

Try this: http://jsfiddle.net/aamir/TaHtz/76/
HTML:
<div id="timer"></div>
​
JS:
var el = document.getElementById('timer');
var milliSecondsTime = 10000;
var timer;
el.innerHTML = milliSecondsTime/1000;
timer = setInterval(function(){
milliSecondsTime = milliSecondsTime - 1000;
if(milliSecondsTime/1000 == 0) {
clearTimeout(timer);
el.innerHTML = 'BOOOOM';
}
else {
el.innerHTML = milliSecondsTime/1000;
}
},1000);
​

If you want to make your own timer.
read this earlier question
How to create a JQuery Clock / Timer

Try setting the format parameter - http://keith-wood.name/countdownRef.html#format
On further reading, this plugin doesn't do milliseconds. At this point, you either have to edit the actual plugin code or find a new plugin.

I completely agree with #Matt Ball's comment.It may also cause the browser to crash.
Why don't you try this solution instead
jQuery 1 minute countdown with milliseconds and callback

I did it like this (generic counter from N to X (X > N)):
var dynamicCounterAddNewValue = 20;
var currentDynamicUpdater;
function dynamicCounterForValueForControlUpdater(_updaterData) {
_updaterData.from += dynamicCounterAddNewValue;
if (_updaterData.from > _updaterData.to) {
_updaterData.from = _updaterData.to;
}
_updaterData.c.html(_updaterData.from.toString());
if (_updaterData.from < _updaterData.to) {
currentDynamicUpdater = setTimeout(
dynamicCounterForValueForControlUpdater,
10,
{
c: _updaterData.c,
from: _updaterData.from,
to: _updaterData.to
}
);
}
else {
clearTimeout(currentDynamicUpdater);
}
return;
}
// _c -> jQuery object (div,span)
// _from -> starting number
// _to -> ending number
function dynamicCounterForValueForControl(_c, _from, _to) {
clearTimeout(currentDynamicUpdater);
dynamicCounterForValueForControlUpdater(
{
c: _c,
from: _from,
to: _to
}
);
return;
}
EDIT: Updated version (more flexible - for N elements one after another):
(input element is Array of elements for making them dynamic-counts)
var dynamicCounterTimeout = 10;
var currentDynamicUpdater;
function odcArray(_odca) {
this.odca = _odca;
return;
}
function odc(_c, _from, _to) {
this.c = _c; // $('#control_id')
this.from = _from; // e.g. N
this.to = _to; // e.g. M => (M >= N)
var di = parseInt(_to / 45, 10);
if (di < 1) {
di = 1;
}
this.dynamicInc = di;
return;
}
function dynamicCounterForValueForControlUpdater(_odca) {
if (
_odca.odca === null
||
!_odca.odca.length
) {
clearTimeout(currentDynamicUpdater);
return;
}
var o = _odca.odca[0];
o.from += o.dynamicInc;
if (o.from > o.to) {
o.from = o.to;
_odca.odca.shift(); // Remove first element
}
o.c.html(o.from.toString());
currentDynamicUpdater = setTimeout(
dynamicCounterForValueForControlUpdater,
dynamicCounterTimeout,
_odca
);
return;
}
function dynamicCounterForValueForControl(_odca) {
clearTimeout(currentDynamicUpdater);
// SETUP all counters to default
for (var i = 0; i < _odca.odca.length; i++) {
_odca.odca[i].c.html(_odca.odca[i].from.toString());
}
dynamicCounterForValueForControlUpdater(
_odca
);
return;
}
