Javascript - Multiple File Uploader with Limit

This Javascript function allows for multiple file uploads and includes a file size limit, however it is missing a maximum number of files allowed to be uploaded.
The function handleFile(e) has the file type and size arguments passed through it but do not know where to introduce a limit on the allowable number of files to be uploaded.

How do I implement a timer to deal each card after 2 seconds?

I have this function which will deal a card to a player, then to a dealer, then to a player and then to a dealer.
I have tried to use setTimeout(function, milliseconds); but it doesn't work. For example, if I set 2 seconds, it will wait for 4 seconds, then deal the 2 cards to the player and then straight away to dealer 2 cards or it will wait for 8 seconds, then in one batch deal all the cards out.
Here are my methods:
const dealOneCardToPlayer = () => {
// Take a card from the top deck to be assigned to tempcard.
tempCard = deck.cards.splice(0, 1);
//console.log(tempCard);
player.cards.push(tempCard);
if (player.cards.length === 5) {
player.canHit = false;
}
if (player.canHit) {
$("#btnHit").show();
} else {
$("#btnHit").hide();
}
player.handValue = countHandValue(player.cards);
makeCardPlayer(tempCard[0]);
}
const dealOneCardToDealer = (holeCard) => {
// Take a card from the top deck to be assigned to tempcard.
tempCard = deck.cards.splice(0, 1);
dealer.cards.push(tempCard);
if (dealer.cards.length === 5) {
dealer.canHit = false;
}
if (dealer.canHit) {
$("#btnHit").show();
} else {
$("#btnHit").hide();
}
dealer.handValue = countHandValue(dealer.cards);
makeCardDealer(tempCard[0],holeCard);
}
const deal = () => {
debugger;
newDeck();
// Option: to burn first card before deal a card
// to the first player
burnOneCard;
dealOneCardToPlayer();
dealOneCardToDealer(false);
dealOneCardToPlayer();
// true for hole card
dealOneCardToDealer(true);
showGameButtons(true);
checkEndGame1();
checkGameOver();

I think the right way to approach is with promises:
const DELAY = 2000;
function dealCardToPlayer() {
return new Promise(function(resolve) {
setTimeout(function() {
console.log('Dealing card to player');
resolve();
}, DELAY);
});
}
function dealCardToDealer() {
return new Promise(function(resolve) {
setTimeout(function() {
console.log('Dealing card to dealer');
resolve();
}, DELAY);
});
}
dealCardToPlayer()
.then(dealCardToDealer)
.then(dealCardToPlayer)
.then(dealCardToDealer);

Add type in animated feature

I wish to create a feature where the letters are typed in between a sentence as it is done in this page .
In the above link there is a sentence inside the banner that says
Create meaningful documents
Create persuasive documents
Create impactful documents
If you notice, the 2nd word is changing while the first and the third word remains the same, can anyone please tell how this animated feature can be achieved

This can be done using javascript. Here is a plugin that i made that types letters using setInterval() function.
Original Demo:
typer = function(e, s, d, t) {
var eI = 0;
var speed = s;
var delay = d;
var eLength = t.length;
var z = 1;
function loop() {
var p = $("<div class='azy-typer-container azy-typer-done'></div>");
var c_t = $("<span class='azy-typer-element'></span>")
var c_b = $("<span class='azy-typer-blinker'>|</span>");
$(".azy-typer-blinker").remove();
p.append(c_t).append(c_b);
$(e).append(p);
interval = setInterval(function() {
c_t.text(t[eI].substring(0, z));
if (z + 1 > t[eI].length) {
clearInterval(interval);
eI = eI + 1;
if (eI + 1 <= t.length) {
z = 0;
setTimeout(loop, d);
}
} else {
z = z + 1;
}
}, s)
}
loop();
}
new typer(".container", 100, 1000, ["Hi there!", "This is a typer demo ", "What do you think about this ?"]);
body {
background: black;
}
span {
font-family: "Courier New";
font-size: 24px;
color: #fff;
font-weight: bold;
}
.azy-typer-blinker {
animation: blink 1s infinite;
}
#keyframes blink {
0% {
color: crimson;
}
50% {
color: transparent;
}
100% {
color: crimson;
}
}
.azy-typer-done {
margin-left: 24px;
}
.azy-typer-done:before {
content: ">>";
color: lightgreen;
font-family: "Courier New";
font-size: 24px;
margin-left: -24px;
font-weight: bold;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div class="container"></div>
You can do some changes to make this code work as you need
typer = function(e, s, d, t) {
var eI = 0;
var speed = s;
var delay = d;
var eLength = t.length;
var z = 1;
function loop() {
var p = $("<div class='azy-typer-container'></div>");
var c_t = $("<span class='azy-typer-element'></span>")
var c_b = $("<span class='azy-typer-blinker'>|</span>");
$(".azy-typer-blinker").remove();
p.append(c_t).append(c_b);
$(e).append(p);
interval = setInterval(function() {
c_t.text(t[eI].substring(0, z));
if (z + 1 > t[eI].length) {
p.addClass("azy-typer-done");
clearInterval(interval);
eI = eI + 1;
if (eI + 1 <= t.length) {
z = 0;
setTimeout(loop, d);
} else {
eI = 0;
z = 0;
setTimeout(loop, d);
}
} else {
z = z + 1;
}
}, s)
}
loop();
}
new typer(".container", 100, 1000, ["Hi there!", "This is a typer demo ", "What do you think about this ?"]);
body {
background: black;
}
span {
font-family: "Courier New";
font-size: 24px;
color: #fff;
font-weight: bold;
}
.azy-typer-blinker {
color: maroon;
}
.azy-typer-container {
display: inline;
}
.azy-typer-done {
display: none;
}
.static {
color: lime;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div class="container">
<span class="static">Static </span>
</div>
The function takes four arguments
The element to which the text is to be appended
The typing speed
The delay for the next item to appear
The text (should be an array)

Javascript end game when click on image

Hey this is my first time on Stackoverflow!
I am building a small javascript html5 game where you click on objects kind of like whack-a-mole.. The goal is to kill as many "gem green" and " gem blue" as possible in 10 seconds, and when you click on the "gem red".. the game ends and plays a sound.
I got most things to work, except I can't find a way to make the game end when clicking on "gem red".. I have tried lots of functions and listeners.. but to no avail.. can anyone help me figure this out?
Here is the code:

Alessio -
You only need a few minor changes to your code to make it work. The example below should help you get started in the right direction. Good luck.
Changes:
Add an endGame() function and move the stop game logic from the timer() function into it.
Add a line to the click() function to check for red gem clicks.
if (target.className.indexOf('red') > 0) endGame("Red Gem - You win!");
Declare the count, counter, and interval variables at the top of your Game object.
The code below also has a few minor CSS changes used for debugging which you can remove.

For starters, you shouldn't include a style sheet and your entire HTML file since neither is relevant and you should use a canvas element instead of this chaotic use of CSS and html elements, which would allow the size of your code to be halved. Furthermore, you should be able to fix this by just changing some global boolean variable to false when the red gem is clicked and when the boolean variable is false (this if statement belongs at the end of your game loop) you call Stop(arg)/clearInterval(arg). Given that your current code doesn't seem to have a global boolean variable indicating game state (using an enumeration would generally be a cleaner solution but a simple boolean seems to suit this case)

Javascript Tooltip Not Working in IE

Hello guys on my blog I use this script:
jQuery(document).ready(function () {
jQuery(".postbox").hover(function () {
tipinfo = $(this).find('.tipinfo');
var t = jQuery(this).position() + jQuery(this).width();
var leftto = t.left + jQuery(this).width() - 30;
tipinfo.css({
top: jQuery(this).position().top + jQuery(this).height() - 2,
left: leftto
});
tipinfo.show(); //vedi tooltip
}, function () {
tipinfo.hide(); //nascondi tooltip
})
});
The tooltip works perfectly with all browsers except IE. I know that the state Hover the browser from Microsoft is not working, so I ask for your help. There is a hack to remedy the problem?
I would be very grateful for your help

.tipinfo {

This like looks wrong to me:
var t = jQuery(this).position() + jQuery(this).width();
Because jQuery(this).position() returns object, but jQuery(this).width() returns integer. Probably you should change it to :
var t = jQuery(this).position();
t.left += jQuery(this).width();

As far as I know you need to add the hover behaviour to IE<8. I don't know if jquery adds this functionality back, include the following line in your CSS:
body {/* ...*/behavior:url("/styles/csshover.htc");}
And the following in csshover.htc (copied with original credit, can find it on the listed page anymore)
<attach event="ondocumentready" handler="parseStylesheets" />
<script language="JScript">
/**
