Dynamically add values to form with javascript or jquery - javascript

I have created a calculator I use for counting carbs for my 7 y/o type 1 diabetic but as I add more values into my array the page is getting too long.
I'm looking for a way to start with a single select for the food name then select the weight and it calculates the carbs. Then have a button to dynamically add another row to the form in order to select a new food item and calculate the results of any further additions.
This is my functional code base:
<html><head>
<meta name = "viewport" content = "initial-scale = 1.0, user-scalable = no">
<title>Carb Calculator</title>
<style>
#container{width: 200px; margin: 0 auto;}
label { font-size:20px; display: inline-block; width: 45%; text-align: right;}
input[type="text"][disabled] {width: 12%; background-color: white; color: black; font-weight: bolder;}
input[type="button"] {}
select {width: 15%}
</style></head>
<body>
<script language="javascript" type="text/javascript">

}
function calculate(){

var tt=0;
for (var i=0; i<myArray.length; i++) {
var v = "val"+i;
var a = "answer"+i;
if(isNaN(parseInt(document.calc.elements[v].value))) {
//document.calc.elements[a].value="";
} else {

document.calc.elements[a].value=tt.toFixed(1);

}
document.calc.answerTot.value=(t).toFixed(1)

Hello there and welcome to StackOverflow!
Your code required a bit of rework and questions like that (more like a task than a question) aren't usually very successful around here.
Having said that, I wrote something that will hopefully help you, the nice thing about it being that if you want to add new types of food you'll only need to add them in the array and the js will take care of it.
Careful with the approximation to 1 digit though, you might lose some carbs in the calculation. Also, please check your carbs, see if I haven't modified anything by mistake.

If anyone wants to see the result, this is what I ended up with. I added a couple event listeners and made the weight value a select rather than an input. Thanks again #Paul for the assistance this is exactly what I was trying to accomplish!

Here is a small application I came up with that could also suit your needs.
It consists of five files that should be located in the same directory.
Best of health for your child!
Features include:
adding and removing of new food types
adding and removing food to/from multiple lists
changing, increasing and decreasing count of fooditems in lists
manage (add,remove,rename) multiple lists
save and load data in your browser locally
export and import data through a text area to save your data externally.
layout support for both big screen and handheld devices

Technical Notes:
I am using pure Javascript and css. Some styles might not be compatible with older browsers like Internet Explorer prior to Edge.
Saving of data is handled through the browsers local storage.
Import and Export is handled through plain text in "Javascript Object Notation" (JSON).
The Application itself is written as a Javascript Class e.g. Function named MyCarbCalculator which is created and initialized through the bodies onload event and an init() function.
With this example application I'm trying to show how to use Javascript in a structured (pseudo object oriented) way and the power and flexibility of event listeners and unnamed functions e.g. the use of functions as parameters.
Also I am using CSS media descriptors to create a flexible layout that can be customized for both handheld devices and big screens. This is mostly done through the "flexbox" style which allows for very fluid layouts and offers great control over the positioning of elements.

How do I make each new input appear in a new box

I want to know how to make it so that when the button is clicked and a new input is added, it does not take the place of the old one, but appears in a new bix leaving the old one.
<!DOCTYPE html>

function to output the item.
function outputname() {
var x=document.getElementById("form1") ;
item = x.elements.namedItem("item").value;
if (item !== ""){
document.getElementById("output").innerHTML=item;

Cant Get What you are trying to do, but maybe this will help:
var i = 0;
var original = document.getElementById('duplicater');
function duplicate() {
i = i + 1;
var clone = original.cloneNode(true);
clone.id = "duplicetor" + ++i;
original.parentNode.appendChild(clone);
}
function outputname() {
var x=document.getElementById("form1") ;
item = x.elements.namedItem("item").value;
if (item !== ""){
var createdItem = document.createElement('P');
createdItem.setAttribute('id', 'output');
var text = document.createTextNode(item);
createdItem.appendChild(text);
var container = document.getElementById("duplicater");
container.appendChild(createdItem);
}
}
this would be CSS:
.box {
border-radius: 5px;
border-width: 1px;
border-color: black;
border-style: solid;
}
#output{
display: block;
background-color: red;
width: 100px;
height: 50px;
}

Generated button's function only works on second click

I have a function that creates an alert box, fills the title field and message with information (error, success, info...) and then adds a button that gets an onclick function to remove the message alert.
When a message is first generated and you click the button nothing happens, but when you click it a second time it'll close the message and works for all messages created later until the page reloads.
var container = document.getElementById('modal-container');
var page = document.getElementById('html');
var current;

var box = document.createElement('div');
box.className = 'modal-message-box';
back.appendChild(box);
if (msgtype == 'error') {
var head = document.createElement('span');
head.className = 'errorheader';
} else if (msgtype == 'info') {
var head = document.createElement('span');
head.className = 'infoheader';
} else if (msgtype == 'success') {
var head = document.createElement('span');
head.className = 'successheader';

play animation on matching pairs in memory game

I'm creating a memory game for my web assignment at uni and I am stuck on how to get my animation playing on match on top of the cards that match.
At the moment, I have been able to get the animation to play on click of the memory_board div, but only works once.
So question 1 - How do you get the animation to work every time you click on the Memory_board div.(It only works once atm, and have to refresh the page to play it again)
My code for the animation to work is:
.sprite {
width:96px;
height:96px;
position: relative;
margin:15px;
}
.toon{
background: url(explode.png);
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script type='text/javascript' src='jquery.animateSprite.js'></script>
<script>//sparkle effect: http://www.rigzsoft.co.uk/how-to-implement-animated-sprite-sheets-on-a-web-page/
$(document).ready(function(){
$("#memory_board").click(function animation(){
$(".toon").animateSprite({
columns: 10,
totalFrames: 50,
duration: 1000,
});
});
});
</script>
<body>
<div class = "grid_10">
<div id="memory_board"></div>
<script>newBoard();</script>
<div style="position: relative; height: 110px;">
<div class="sprite toon"></div>
</div>
</div>
</body>
Question 2 - How will I place this animation over top of each card?
The layout of the board is by float in the memory_boarddiv, where the images are in an array and called up in the function tile.innerHTML = '<img src="' + val + '.png"/>';
Here is the full coding for the board:
div#memory_board{
background: -webkit-radial-gradient(#FFF, #CC99FF); /* For Safari 5.1 to 6.0 */
background: -o-radial-gradient(#FFF, #CC99FF); /* For Opera 11.1 to 12.0 */
background: -moz-radial-gradient(#FFF, #CC99FF); /* For Firefox 3.6 to 15 */
background: radial-gradient(#FFF, #CC99FF); /* Standard syntax (must be last) */
border:#FF0066 10px ridge;
width:510px;
height:405px;
padding:24px;
}
div#memory_board > div{
background:url(tile_background.png) no-repeat;
border:#000 1px solid;
width:45px;
height:45px;
float:left;
margin:7px;
padding:20px;
cursor:pointer;
}

<script>newBoard();</script>
<div style="position: relative; height: 110px;">
<div class="sprite toon"></div>
</div>
</div>
</body>
Question 3 - How will I get to play this animation only on match, on top of the cards that have matched.
I'm guessing this is done by putting it into the memoryFlipTile function under the //animation where the sound and match number change upon a match found :
function memoryFlipTile(tile,val){
startTimer();
playClick();
if(tile.innerHTML == "" && memory_values.length < 2){
tile.style.background = '#FFF';
tile.innerHTML = '<img src="' + val + '.png"/>';
if(memory_values.length == 0){
memory_values.push(val);
memory_tile_ids.push(tile.id);
} else if(memory_values.length == 1){
memory_values.push(val);
memory_tile_ids.push(tile.id);
if(memory_values[0] == memory_values[1]){
tiles_flipped += 2;
//sound
playMatch();
//animation
//number of clicks
turns = turns + 1;
document.getElementById("Count").innerHTML = turns;
//number of matches
matches = matches + 1;
document.getElementById("matchNumber").innerHTML = matches;
// Clear both arrays
memory_values = [];
memory_tile_ids = [];

Image series bar

I have for example image of Coin.
I want to give a value from 0 to example 20.
0: no coin
1: to one coin
2: 2 coin etc
20: 20 coin
The collection of 6 coins should looks like this:
How can I achieve this goal?
if you prefer pure JS:
var maxI = Math.floor(Math.random() * (21 - 1)) + 1;
var marginCoins = 0;
var coin = [];
for (var i = 0; i < maxI; i++) {
coin[i] = document.createElement('img');
coin[i].src = 'http://placehold.it/75x75';
coin[i].style.position = 'fixed';
coin[i].style.top = marginCoins+'px';
coin[i].style.height = '75px';
coin[i].style.border = '1px solid black';
document.body.appendChild(coin[i]);
marginCoins += 45;
}
$(".coins").each(function(){
var $self = $(this);
var applyCoins = function(){
$self.empty();
var coins = $self.data("coins");
for (var i=coins-1; i>=0; i--) {
var $coin = $("<div></div>").addClass("coin").css("top", (i*20)+"px");
$self.append($coin);
}
};
$self.on("loadCoins", function(){
applyCoins();
});
applyCoins();
});
$("#button").click(function(){
$(".coins").data("coins", $("#input").val()).trigger("loadCoins");
});
.coins {
width: 120px;
height: 120px;
position: relative;
overflow: visible;
}
.coins .coin {
width: 120px;
height: 120px;
position: absolute;
top: 0;
left: 0;
background-color: #FF0000;
border-bottom: 3px solid #333333;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<p>
<input type="text" value="3" id="input" />
<input type="button" value="change" id="button" />
</p>
<div class="coins" data-coins="10"></div>
