Trying to run one function after the other using JS

I've been having some trouble running one function that slowly displays a message, waits, then fades out. However, you'll notice when the button is clicked to drop the confetti and display the message, the confetti doesn't stop.
I'm still learning Javascript, and am not that experienced with it yet. But I pieced this together to get what I'm looking for as an end result.
What I'd like to happen is when the button is clicked, the message fades in, confetti falls, message fades and confetti stops falling but allows the last bit of confetti to fall until its off screen...
It's probably because I don't understand Javascript to this level yet, but I'm having a really hard time getting the JS to do what I'm wanting...
Can anyone give me some pointers in my code to help guide me in the right direction?
Thanks!!

The fadeOut() has one callback where you pass what should happen when animation is over.You must have tried this but reason why it didn't work is that most of your js code is in a self executing function which forms a different scope so you cannot call any method inside this scope from outside.I have moved the stuff inside now it works.Not much change there just changed a few lines; marked with NEWLY ADDED

Canvas responsive scroll

I use sketch.js plugin in my website but If I use it will be not responsive and the horizontal scroll will be appear I don't need to depend on body { overflow: hidden }so what is the solution:
Here my code:
// ----------------------------------------
// Particle
// ----------------------------------------
function Particle(x, y, radius) {
this.init(x, y, radius);
}
Particle.prototype = {
init: function (x, y, radius) {
this.alive = true;
this.radius = radius || 10;
this.wander = 0.15;
this.theta = random(TWO_PI);
this.drag = 0.92;
this.color = '#fff';
this.x = x || 0.0;
this.y = y || 0.0;
this.vx = 0.0;
this.vy = 0.0;
},
move: function () {
this.x += this.vx;
this.y += this.vy;
this.vx *= this.drag;
this.vy *= this.drag;
this.theta += random(-0.5, 0.5) * this.wander;
this.vx += sin(this.theta) * 0.1;
this.vy += cos(this.theta) * 0.1;
this.radius *= 0.96;
this.alive = this.radius > 0.5;
},
draw: function (ctx) {
ctx.beginPath();
ctx.arc(this.x, this.y, this.radius, 0, TWO_PI);
ctx.fillStyle = this.color;
ctx.fill();
}
};
// ----------------------------------------
// Example

Calling a function of an external Javascript on button click

I use this SVG Pie Chart on my website. It has a pretty animation on load (as you can see by running the snippet below) but I don't want it to be visible by default. I want it show up with its animation on a button click after the page is loaded.
Its probably controlled by triggerAnimation(); function in pie.js but it gets called automatically when the page is loaded as the script is external.
 <!-- Pie chart JS-->
<script src="js/pie.js"></script>
How can I control the function from a button click? Help would be appreciated.
Below is a live snippet of the pie chart :
PIE.js, PIE.css and PIE.html
$(function(){
$("#pieChart").drawPieChart([
{ title: "Tokyo", value : 180, color: "#02B3E7" },
{ title: "San Francisco", value: 60, color: "#CFD3D6" },
{ title: "London", value : 50, color: "#736D79" },
{ title: "New York", value: 30, color: "#776068" },
{ title: "Sydney", value : 20, color: "#EB0D42" },
{ title: "Berlin", value : 20, color: "#FFEC62" },
{ title: "Osaka", value : 7, color: "#04374E" }
]);
});

Tearable Cloth simulation works on Codepen but not locally

I am trying to include this Codepen into a basic website for school.
The issue is that the code with a few tweaks, will not load locally. I have even put my entire website into Codepen as a test and it worked.
It should just be the cloth simulation and nothing else.
Here is the HTML and CSS in its smallest form.
<!doctype html>
<html>
<head>
<style>
body {
background: #2F4F4F;
}
#c {
display: block;
margin: 20px auto 0;
}
</style>
<meta charset="utf-8">
<title>Test</title>
<script type="text/javascript" src="Website/JavaScript/ClothSimulation.js"></script>
</head>
<body>
<canvas id="c"></canvas>
<div id="top">
<a id="close"></a>
</div>
</body>
</html>
The JS is very big as it is a cloth simulation.
document.getElementById('close').onmousedown = function(e) {
e.preventDefault();
document.getElementById('info').style.display = 'none';
return false;
};
// settings

Thank you for your help.

Assuming you have copy and pasted the website exactly how it is, you're missing opening and closing style tags around the CSS, and script tags around the JS.

Your code works, but you need this tags:
<script type="text/javascript"> YOUR JAVASCRIPT HERE </script>
<style type="text/css"> YOUR CSS HERE </style>

Removing mousemove

I'm developing an app to help autistic children prepare to learn to write. It's very straight forward. They just need to draw a line straight down. I have it working very similar to "connect the dots" where they start at a green light, progress to yellow and then to red. However, on my webpage using a mouse everything works great because the "dots" are "touched" using the mouseover, like so:
<script type="text/javascript" src="jquery-1.4.2.min.js"></script>
