jQuery : Dynamic HTML onClick - html

I am trying to create dynamically generated elements when the user clicks on a button. The should slide in from the right, and when the button is clicked again, another should slide in from the right. For some reason, it is not doing exactly what I need it to do. Here's the code:
<html>
<head>
<title>Chat Head</title>
<link rel="stylesheet" type="text/css" href="http://maxcdn.bootstrapcdn.com/bootstrap/3.1.1/css/bootstrap.min.css">
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.10.4/jquery-ui.min.js"></script>
<script type="text/javascript" src = "http://maxcdn.bootstrapcdn.com/bootstrap/3.1.1/js/bootstrap.min.js"></script>
<script>
$(document).ready(function(){
screenWidth = $(window).width();
screenHeight = $(window).height();
msgWidth = 0.7*screenWidth;
msgHeight = 0.7*screenHeight;
$("#note").css("width", msgWidth);
$("#note").css("height", msgHeight);
$("#slide").click(function(){
var textArea = '<textarea class = form-control rows = "3" id = "text"></textarea>';
$(textArea).appendTo('.note');
var effect = 'slide';
var duration = 1000;
$(".note").toggle(effect, {direction: 'right'}, duration);
});
});
</script>
</head>
<style type="text/css">
.note{
display: none;
}
</style>
<body>
<div class="row">
<div class="col-md-12">
<button class = "button" id = "slide">Slide</button>
<hr />
<div class="note">
<!-- <textarea class = "form-control" rows = "2" id = "note"></textarea> -->
</div>
</div>
</div>
</body>
</html>
Here's the JS Fiddle that goes with the code:
http://jsfiddle.net/ma6Jq/2/

Here is an implementation I came up with. http://jsfiddle.net/Ar7qw/1/
<script>
$(document).ready(function(){
var count = 0;
$("#slide").click(function(){
count = count + 1;
screenWidth = $(window).width();
screenHeight = $(window).height();
msgWidth = 0.7*screenWidth;
msgHeight = 0.7*screenHeight;
$("#note"+ count).css("width", msgWidth);
$("#note"+ count).css("height", msgHeight);
var newnote = '<div class="note' + count +'"></div>';
$(newnote).appendTo('.col-md-12');
var textArea = '<textarea class="form-control" rows = "3" id = "text"></textarea>';
$(textArea).appendTo('.note' + count);
$('.note' + count).effect('slide', {direction: 'right'}, 1000);
});
});
</script>

This gets you close. I'm out of time for now.
http://jsfiddle.net/isherwood/ma6Jq/10
.note-box {
margin-left: 150%;
}
.done {
margin-left: 10px;
transition: all 1s;
}
$("#slide").click(function () {
var textArea = '<textarea class="form-control note-box" rows="3"></textarea>';
var duration = 1000;
$(textArea).appendTo('#note').addClass('done', duration);
});

Another implementation for anybody needing one(or a couple different choices of solutions)
http://jsfiddle.net/ma6Jq/13/
var counter = 0;
$("#slide").click(function () {
counter ++;
var textArea = '<div class="note' + counter + '"><textarea class ="form-control" rows = "3" id = "text">'+ counter +'yo</textarea></div>';
$(textArea).appendTo('.note');
var effect = 'slide';
var duration = 1000;
var stringhere = ".note" + counter;
$(stringhere).effect('slide',
{
direction:'right'
}, duration);
/*
$(stringhere).animate({
marginLeft: parseInt($(stringhere).css('marginLeft'),1000) == 0 ?
$(stringhere).outerWidth() :
100
});
*/
/*
$(stringhere).toggle(effect, {
direction: 'left'
}, duration);
*/
});
});

How can i fix the setInterval part, is that even it?

I'm working on a game named Factory Tycoon and have spotted a bug which I can't resolve myself. Every second you get plus what your items per second is on your items but it is failing to do so. Feel free to test the code. Code:
<!DOCTYPE html>
<html>
<head>
<title>Factory Tycoon</title>
<script type="text/javascript">
var money = 1000;
var items = 0;
var itemsps = 1;
var dropper1Cost = 100;
var dropper1Audio = new Audio('Audio/dropper1Sound.mp3');
function addDropper() {
if (money <= dropper1Cost - 1) {
alert('Not Enough Money.')
}
if (money >= dropper1Cost) {
dropper1Audio.play()
itemsps += 1;
money -= dropper1Cost;
dropper1Cost += 100;
}
}
setInterval(function renderMoney() {
document.getElementById('money').innerHTML = "Money:" + money;
})
setInterval(function renderItemsProcessedPS() {
document.getElementById('items').innerHTML = "Items Processed:" + items;
})
setInterval(function renderItemsProcessedPS() {
document.getElementById('itemsps').innerHTML = "Items Processed Per Second:" + itemsps;
}, 1000)
</script>
</head>
<h4 id="money"></h4>
<h4 id="items"></h4>
<h4 id="itemsps"></h4>
<body>
<img src="Images/dropper1IMG.png" onclick="addDropper()">
</html>
There isn't much code as I've only just started to develop it tonight :).
There is a few issues in the code:
<h4> elements need to be inside the <body> element
the </body> end tag is missing
the setInterval is called before all elements had a chance to load, which will make it error, so I wrapped them in an init function and called that on body load
Side note, this code can be optimized with addEventListener for the load event etc., but here you have a start
<!DOCTYPE html>
<html>
<head>
<title>Factory Tycoon</title>
<style>
span { display: inline-block; padding: 5px; background: #ddd; }
</style>
<script type="text/javascript">
var money = 1000;
var items = 0;
var itemsps = 1;
var dropper1Cost = 100;
var dropper1Audio = new Audio('Audio/dropper1Sound.mp3');
function addDropper() {
if (money <= dropper1Cost - 1) {
alert('Not Enough Money.')
}
if (money >= dropper1Cost) {
dropper1Audio.play()
itemsps += 1;
money -= dropper1Cost;
dropper1Cost += 100;
}
}
function init() {
setInterval(function renderMoney() {
document.getElementById('money').innerHTML = "Money:" + money;
})
setInterval(function renderItemsProcessedPS() {
document.getElementById('items').innerHTML = "Items Processed:" + items;
})
setInterval(function renderItemsProcessedPS() {
document.getElementById('itemsps').innerHTML = "Items Processed Per Second:" + itemsps;
}, 1000)
}
</script>
</head>
<body onload="init();">
<h4 id="money"></h4>
<h4 id="items"></h4>
<h4 id="itemsps"></h4>
<span onclick="addDropper()">Click Me</span>
</body>
</html>

Overlapping css

I am a 3 month beginner. I'm currently working on a simple game, to try different skills I learned recently and I have a problem I couldn't solve with Google.
My JS code generates a grid made out of divs, (coordinates in ID), and appends a child (the player) once they're here, but I can't get to display the player image. I previously just gave the div a #player id but I changed and tried appending the player as a child div, because later it'll be easier to move a div around rather than removing and adding IDs (when making player controls).
Here's my code:
The CSS
.tile{
margin:2px;
height:50px;
width:50px;
border:1px solid black;
display: inline-block;
}
#map{
height:482px;
width:730px;
background-image:url(bg.png);
}
#player{
background-image:url(player.png);
}
#monster{
background-image:url(monster.png);
}
#start{
margin:auto;
color:white;
background-color:grey;
border:2px solid black;
}
The JavaScript
var game = function(){
$("#hgrass").hide()
$("#htile").hide()
$("#hmnstr").hide()
$("#hplayr").hide()
$("#start").click(function(){startGame();
});
var genMap = function(){
var map = document.createElement("div");
document.body.appendChild(map);
map.setAttribute("id","map")
for(c=0;c<8;c++){
for(r = 0;r<13;r++){
var tile = document.createElement("div");
var tileId = c+"/"+r;
tile.setAttribute("id",tileId);
tile.setAttribute("class","tile");
map.appendChild(tile);
}
}
}
var spawnPlayer = function(){
var rrow = (Math.floor((Math.random() * 8)));
var rcol = (Math.floor((Math.random() * 13)));
var prow = rrow.toString();
var pcol = rcol.toString();
var coord = document.getElementById(prow+"/"+pcol)
var player = document.createElement("div")
player.setAttribute("id","player")
coord.appendChild(player)
}
var spawnMonster = function(){
var rrow = (Math.floor((Math.random() * 8)));
var rcol = (Math.floor((Math.random() * 13)));
var prow = rrow.toString();
var pcol = rcol.toString();
var monster = document.getElementById(prow+"/"+pcol)
monster.setAttribute("id","monster")
}
/*var turns = function(){
var pturn = true
$(document).keypress(function(event){
var pla = document.getElementById("player")
if (event.which == 37){
pla.removeAttribute("id","player");
pturn = false;
}
});
};*/
var startGame = function(){
genMap();
spawnPlayer();
spawnMonster();
// turns();
$("#start").hide()
$("#hgrass").show()
$("#htile").show()
$("#hmnstr").show()
$("#hplayr").show()
}
};
And the HTML
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8"/>
<link type="text/css" rel="stylesheet" href="test.css"/>
<script src="test.js"></script>
<script src="jquery-3.1.0.js"></script>
</head>
<body onload="game()">
<button type="button" id="start">Click to start</button>
<button type="button" id="hgrass">Click to hide grass
<button type="button" id="htile">Click to hide tiles</button>
<button type="button" id="hmnstr">Click to hide monster</button>
<button type="button" id="hplayr">Click to hide player</button>
</body>

How to apply z-index for fabric js handlers

setTimeout(function () {
var myImg = document.querySelector("#background");
var realWidth = myImg.naturalWidth;
var realHeight = myImg.naturalHeight;
$("canvas").attr("width", realWidth);
$("canvas").attr("height", realHeight);
var source = document.getElementById('background').src;
var canvas = new fabric.Canvas('canvas');
canvas.width = realWidth;
canvas.height = realHeight;
var ctx = canvas.getContext('2d');
document.getElementById('file').addEventListener("change", function (e) {
var file = e.target.files[0];
var reader = new FileReader();

var oImg = img.set({
left: 320
, top: 180
, angle: 00
, width: 200
, height: 200
});
canvas.add(oImg).renderAll();
var a = canvas.setActiveObject(oImg);
var dataURL = canvas.toDataURL({
format: 'png'
, quality: 0.8
});
});
};
reader.readAsDataURL(file);
});
canvas.setOverlayImage(source, canvas.renderAll.bind(canvas), {
backgroundImageOpacity: 0.5
, backgroundImageStretch: false
});
canvas.on('mouse:over', function (e) {
canvas.item(0).hasBorders = true;
canvas.item(0).hasControls = true;
canvas.setActiveObject(canvas.item(0));

I am using fabric js to build a facemask application when i have two images
1) Image without face which is applied to canvas using setOverlayImage method
2) Only head where the user will upload and adjust accordingly.
I have almost done with functionality but I want to show fabric handlers above the first image where now they are hiding behind first image.
Reference Image : Click here for reference Image
Please find the Run Code Snippet
I think all you need to do is specify controlsAboveOverlay when you get the fabric instance.
var canvas = new fabric.Canvas('canvas', {
controlsAboveOverlay : true
});

Switching from one image to another

I'm trying to figure out how to switch from one image to another after 500 ms. What I have currently keeps switching between images, but I want each image to display for 500 ms and to have the second image disappear after that 500 ms instead of having it loop. This is what I have right now:
<html>
<head>
<title>loop</title>
<script type = "text/javascript">
function displayNextImage() {
x = (x === images.length - 1) ? 0 : x + 1;
document.getElementById("img").src = images[x];
}
function displayPreviousImage() {
x = (x <= 0) ? images.length - 1 : x - 1;
document.getElementById("img").src = images[x];
}
function startTimer() {
setInterval(displayNextImage, 500);
}
var images = [], x = -1;
images[0] = "image1.jpg";
images[1] = "image2.jpg";
</script>
</head>
</html>
<body onload = "startTimer()">
<img id="img" src="image1.jpg">
</body>
</html>
Can anyone help me fix this? Thank you!
This should do what you want it to do:
<html>
<head>
<title>loop</title>
<script type = "text/javascript">
var images = [];
var x = 0;
var $img = document.getElementById("img");
images[0] = "image1.jpg";
images[1] = "image2.jpg";
function displayNextImage() {
if (++x < images.length) {
$img.src = images[x];
setInterval(displayNextImage, 500);
}
else {
$img.remove();
}
}
function startTimer() {
setInterval(displayNextImage, 500);
}
</script>
</head>
</html>
<body onload = "startTimer()">
<img id="img" src="image1.jpg">
</body>
</html>

Infinite loading

I followed a tutorial for infinite loading. I managed this code, but the background just keeps loading again and again. I want to display my content just once. Can anyone help me please? Here's the code.
<!DOCTYPE html>
<html>
<head>
<script type="text/javascript">
function yHandler(){
// Watch video for line by line explanation of the code
// http://www.youtube.com/watch?v=eziREnZPml4
var wrap = document.getElementById('wrap');
var contentHeight = wrap.offsetHeight;
var yOffset = window.pageYOffset;
var y = yOffset + window.innerHeight;
if(y >= contentHeight){
// Ajax call to get more dynamic data goes here
wrap.innerHTML += '<div class="newData"></div>';
}
var status = document.getElementById('status');
status.innerHTML = contentHeight+" | "+y;
}
window.onscroll = yHandler;
</script>
<style type="text/css">
div#status{position:fixed; font-size:24px;}
div#wrap{width:800px; margin:0px auto;}
div.newData{height:1000px; background:#09F; margin:10px 0px;}
</style>
</head>
<body>
<div id="status">0 | 0</div>
<div id="wrap"><img src="http://images.bwwstatic.com/tvnetworklogos/1470470F-930B-5791-2D55F77DC33EBA96.jpg"></div>
</body>
</html>
by setting the window.onscroll to null you essentially have a "fire once" event.
<script type="text/javascript">
function yHandler(){
var wrap = document.getElementById('wrap');
var contentHeight = wrap.offsetHeight;
var yOffset = window.pageYOffset;
var y = yOffset + window.innerHeight;
if(y >= contentHeight){
// Ajax call to get more dynamic data goes here
wrap.innerHTML += '<div class="newData"></div>';
window.onscroll = null;
}
var status = document.getElementById('status');
status.innerHTML = contentHeight+" | "+y;
}
window.onscroll = yHandler;
</script>
