JavaScript animations not working (no button flash) and no audio when button clicked

JavaScript animations not working (no button flash) and no audio when button clicked - javascript

I am working on an online boot camp project and could not get my code to create the proper animation. When I press one of the colored buttons, it should flash, but nothing happens. I downloaded the solution file and it also does not work.
I also tried adding:
console.log(userClickedPattern);
playSound(userChosenColor);
to the bottom of the:
$("#btn").click(function(){}
but that did not seem to make a difference.
What am I doing wrong?
var buttonColors = ["red", "blue", "green", "Yellow"];
var gamePattern = [];
var userClickedPattern = [];
$("#btn").click(function() {
var userChosenColor = $(this).attr("id");
userClickedPattern.push(userChosenColor);
playSound(userChosenColor);
animatePress(userChosenColor);
});
function nextSequence() {
var randomNumber = Math.floor(Math.random() * 4);
var randomChosenColor = buttonColors[randomNumber];
gamePattern.push(randomChosenColor);
$("#" + randomChosenColor).fadeIn(100).fadeOut(100).fadeIn(100);
playSound(randomChosenColor);
}
function playSound(name) {
var audio = new Audio("sounds/" + name + ".mp3");
audio.play();
}
function animatePress(currentColor) {
$("#" + currentColor).addClass("pressed");
setTimeout(function() {
$("#" + currentColor).removeClass("pressed");
}, 100);
}
body {
text-align: center;
background-color: #011F3F;
}
#level-title {
font-family: 'Press Start 2P', cursive;

You forgot to define class pressed also your selector for the buttons was wrong #btn instead of .btn
var buttonColors = ["red", "blue", "green", "Yellow"];
var gamePattern = [];
var userClickedPattern = [];
$(".btn").click(function() {
var userChosenColor = $(this).attr("id");
userClickedPattern.push(userChosenColor);
playSound(userChosenColor);
animatePress(userChosenColor);
});
function nextSequence() {
var randomNumber = Math.floor(Math.random() * 4);
var randomChosenColor = buttonColors[randomNumber];
gamePattern.push(randomChosenColor);
$("#" + randomChosenColor).fadeIn(100).fadeOut(100).fadeIn(100);
playSound(randomChosenColor);
}
function playSound(name) {
var audio = new Audio("sounds/" + name + ".mp3");
audio.play();
}
function animatePress(currentColor) {
$("#" + currentColor).addClass("pressed");
setTimeout(function() {
$("#" + currentColor).removeClass("pressed");

I'm trying to do Simon Game. But audio doesn't work on my chrome browser. What to do?

The animations work perfectly on shapes. But audio files dont play. What might be the reason?
I added all the html, css, and javascript files for you to see.
It still doesnt let me post it, so i am extending the question. I hope someone can solve this issue. Thank you in advance. I'd be so happy for your help
var buttonColours = ["red","blue","green","yellow"];
var gamePattern = [];
function nextSequence() {
var randomNumber = Math.floor(Math.random()*4); // 0-3
var randomChosenColour = buttonColours[randomNumber];
gamePattern.push(randomChosenColour);
//1. Use jQuery to select the button with the same id as the randomChosenColour
$("#"+randomChosenColour).fadeIn().fadeOut().fadeIn();
var audio = new Audio("sounds/" + randomChosenColour + ".mp3");
audio.play();
}
nextSequence();

jQuery animation doesn't work with SAPUI5

I'm constructing a tree-view that slides out based on the buttons the user clicks in the preceding column. I get this error when I click on the first column of buttons:
Uncaught TypeError: $(...).effect is not a function
at runEffect1 (test:39)
at HTMLDivElement.<anonymous> (test:66)
at HTMLDivElement.dispatch (jquery-dbg.js:4737)
at HTMLDivElement.c3.handle (jquery-dbg.js:4549)
How do I fix it? These functions worked when I used vanilla JavaScript and without the SAPUI5 imported, but using jQuery now gives problems. I need to use SAPUI5 with jQuery. Also, the snippet doesn't work due to adding SAPUI5.
$(document).ready(function() {
$(function() {
// run the currently selected effect
function runEffect1() {
var selectedEffect = "slide";
var options = {};
/* Hide the columns so that they can slide into display*/
$("#column_2").hide();
$("#column_3").hide();
$("#column_4").hide();
// Run the effect
$("#column_2").effect(selectedEffect, options, 450, function() {
$("#column_3").effect(selectedEffect, options, 450, function() {
$("#column_4").effect(selectedEffect, options, 450, callback);
});
});
};
// Callback function to bring a hidden box back
function callback() {
setTimeout(function() {
$("#effect").removeAttr("style").hide().fadeIn();
}, 100);
};
// Set effect from select menu value

it was sap-ui-core.js causing problem; using jQuery noConflict.
$.noConflict();
$(document).ready(function() {

Normally you don't need the following code in your HTML, because they are duplicated
<script src="https://code.jquery.com/jquery-1.12.4.js"></script>
<script src="https://code.jquery.com/ui/1.12.1/jquery-ui.js"></script>
And where did you place the js code? The $(document).ready(function(){ one. It must be place after the all of the js library.

Dividing a website into 3 sections -> 1 horizontally and 2 vertically below

i have a Sidebar on the left of the Screen. I can toggle it by pressing a button. On the right I have the content.
I want to place the button on a horizontal bar on the top. The sidebar seems to cover this bar so I can not see the button.
This is my current code:
The Html File:

mainAreaWidth = "200px";
}
$("#sideNav").width(sideNavWidth);
$("#mainArea").css('margin-left',mainAreaWidth);
navIsOpen = !navIsOpen;
}
function SaveEntry(){ // save the entry
var txtTitle = $("#titleInputField").val();
var txtField = $("#textArea").val();
alert(txtTitle + "#" + txtField);
}
function NewEntry() { // create a new entry
alert("neuer Eintrag");
}
This is what I want to archieve
It seems I just have to fix the CSS to get it done.

I added margin-top:0; to your topBar and removed top: 0; from your sideNav.
Try this:
var navIsOpen = true;
function InitDocument(){ // Initialization
ToggleNavbar();
}
function ToggleNavbar(){ // show - hide the navbar
var sideNavWidth = "0px";
var mainAreaWidth = "0px";
if (navIsOpen)
{
sideNavWidth = "200px";
mainAreaWidth = "200px";
}
$("#sideNav").width(sideNavWidth);
$("#mainArea").css('margin-left',mainAreaWidth);
navIsOpen = !navIsOpen;
}
function SaveEntry(){ // save the entry
var txtTitle = $("#titleInputField").val();
var txtField = $("#textArea").val();
alert(txtTitle + "#" + txtField);

Take a look flex-box concepts

Checkout this example of using the new HTML5 semantic elements.
http://www.w3schools.com/html/html5_semantic_elements.asp
I have taken most of the example elements from the link above and created a simple HTML5 page.
You can add/remove/modify any of the section below by removing the HTML or removing/adding additional CSS properties.
var toggleButton = document.getElementById('toggle-button');
var pageWrapper = document.getElementsByClassName('wrapper')[0];
toggleButton.addEventListener('click', function() {
toggleClass(pageWrapper, 'toggle-hidden')
});
function toggleClass(el, className) {
if (el.classList) {
el.classList.toggle(className);
} else {
var classes = el.className.split(' ');
var existingIndex = classes.indexOf(className);
if (existingIndex >= 0) classes.splice(existingIndex, 1);
else classes.push(className);
el.className = classes.join(' ');
}

Creating a function to be called again and again

I want to create a simple text game of choices of sorts where you always have two choices and depending on your choice, something is displayed and the current content disappears. My problem is each of the choices are different so i can't figure out a way to not repeat myself again and again in the javascript code.
HTML :
<!Doctype html>
<html>
<head>
<script type="text/javascript" src="jquery-2.1.4.min.js"></script>
<link rel="stylesheet" href="style.css" type="text/css"/>
<title>Game</title>
</head>
<body>
<div id="console">
<div class="storyCard" id="start">
<p class="q">Some stuff.
<p class="a">getup</p>
<p class="a">sleep</p>
</div>
<div class="storyCard" id="getup">
<p class="q">Something happened</p>
<p class="a">do this</p>
<p class="a">do that</p>
</div>
<div class="storyCard" id="sleep">
<p class="q">something else happened</p>
<p class="a">do something</p>
<p class="a">do something else</p>
</div>
<!--and there will be a lot of such storyCards based on the choices.-->
</div>
<script type="text/javascript" src="js.js"></script>
</body>
</html>
CSS :
body {
margin: 0 auto;
align-content: center;
font-family: 'Open Sans', sans-serif;
font-weight: 400;
}
#console {
width: 100%;
}
.storyCard {
min-width: 100px;
max-width: 600px;
background-color: rgba(0, 0, 0, 0.51);
box-shadow: 1px 1px 7px;
padding: 50px;
color: white;
margin: 0 auto;
border-radius: 4px;
display: none;
}
#start {
display: block;
}
.storyCard .a {
background-color: dodgerblue;
border-bottom-color: dodgerblue;
border-top-color: white;
border-left-color: white;
border-right-color: dodgerblue;
padding: 10px;
text-align: center;
color: white;
width: 30%;
display: inline;
margin: 0 auto;
box-shadow: 1px 1px 7px black;
float: right;
cursor: pointer;
}
.storyCard .a:hover {
background-color: white;
color: black;
}
}
Javascript :
document.querySelector('#console').addEventListener('click', function (e) {
var answer = e.target.textContent;
switch (answer) {
case 'getup':
e.target.parentNode.style.display = 'none';
document.querySelector('#getup').style.display = 'block';
break;
case 'sleep':
e.target.parentNode.style.display = 'none';
document.querySelector('#sleep').style.display = 'block';
break;
case 'do this':
e.target.parentNode.style.display = 'none';
/*display another content like above*/
case 'do that':
/*hide the current content again and display another content and add more cases*/
}, false);

I assume that the question must defined in html like your sample. There are many others way to do this better.
You can use class name to specify next question.
document.addEventListener('click', function (e) {
var target = e.target;
if (target.className.match('answer')) {
var nextQuestionId = target.className.replace('answer ', '');
hideAllStoryCards();
showStoryCard(nextQuestionId);
}
});
function hideAllStoryCards () {
var i, elm, elms = document.getElementsByClassName('storyCard');
for (i = 0; i < elms.length; i++) {
elm = elms[i];
elm.style.display = 'none';
}
}
function showStoryCard (id) {
var storyCard = document.getElementById(id);
storyCard.style.display = 'block';
}
hideAllStoryCards();
showStoryCard('first-question');
<div id="console">
<div class="storyCard" id="first-question">
<p class="q">Are you hungry?</p>
<p class="answer what-do-you-want-to-eat">yes</p>
<p class="answer may-i-help-you">no</p>
</div>
<div class="storyCard" id="what-do-you-want-to-eat">
<p class="q">Some stuff.</p>
<p class="answer NEXT_QUESTION_ID">a pie</p>
<p class="answer ANOTHER_QUESTION_ID">a buger</p>
</div>
<div class="storyCard" id="may-i-help-you">
<p class="q">Some stuff.</p>
<p class="answer NEXT_QUESTION_ID">bye</p>
<p class="answer ANOTHER_QUESTION_ID">bye again</p>
</div>
</div>

You can try something like performAction(e, '#getup'); - a generalized method with parameters, in this link.
Please refer below for the code:
HTML:
<div id="console">
<div class="storyCard" id="start">
<p class="q">Some stuff.</p>
<p class="a">getup</p>
<p class="a">sleep</p>
</div>
<div class="storyCard" id="getup">
<p class="q">Something happened</p>
<p class="a">do this</p>
<p class="a">do that</p>
</div>
<div class="storyCard" id="sleep">
<p class="q">something else happened</p>
<p class="a">do something</p>
<p class="a">do something else</p>
</div>
<!--and there will be a lot of such storyCards based on the choices.-->
</div>
CSS:
body {
margin: 0 auto;
align-content: center;
font-family: 'Open Sans', sans-serif;
font-weight: 400;
}
#console {
width: 100%;
}
.storyCard {
min-width: 100px;
max-width: 600px;
background-color: rgba(0, 0, 0, 0.51);
box-shadow: 1px 1px 7px;
padding: 50px;
color: white;
margin: 0 auto;
border-radius: 4px;
display: none;
}
#start {
display: block;
}
.storyCard .a {
background-color: dodgerblue;
border-bottom-color: dodgerblue;
border-top-color: white;
border-left-color: white;
border-right-color: dodgerblue;
padding: 10px;
text-align: center;
color: white;
width: 30%;
display: inline;
margin: 0 auto;
box-shadow: 1px 1px 7px black;
float: right;
cursor: pointer;
}
.storyCard .a:hover {
background-color: white;
color: black;
}
JS:
document.querySelector('#console').addEventListener('click', function(e) {
var answer = e.target.textContent;
switch (answer) {
case 'getup':
performAction(e, '#getup');
break;
case 'sleep':
performAction(e, '#sleep');
break;
case 'do this':
performAction(e, '#getup'); /**Use any 'id' or target of your choice.*/
/*display another content like above*/
break;
case 'do that':
performAction(e, '#getup'); /*Use any 'id' or target of your choice.*/
/*hide the current content again and display another content and add more cases*/
break;
}
}, false);
function performAction(event, target) {
event.target.parentNode.style.display = 'none';
document.querySelector(target).style.display = 'block';
}

You need to separate your data from your UI.
Your data could be something simple like this:
var stories;
function StoryCard(q, option1, option2) {
this.q = q
this.option1 = option1;
this.option2 = option2;
}
function displayStory(storyCard) {
document.getElementById('q').innerHTML = storyCard.q;
document.getElementById('option1').innerHTML = storyCard.option1;
document.getElementById('option2').innerHTML = storyCard.option2;
}
Your "console" UI could change to something more like this:
<div id="console">
<div class="storyCard" id="start">
<p class="q" id="q"> </p>
<p class="a" id="option1"> </p>
<p class="a" id="option2"> </p>
</div>
</div>
Your click function may be more like this:
document.querySelector('#console').addEventListener('click', function (e) {
var answer = e.target.id;
switch (answer) {
default: // for when they click within the div, but not on an option
break;
case 'option1':
case 'option2':
var story = stories[e.target.innerHTML];
if (null != story) {
displayStory(story);
}
break;
}
}, false);
You would set up your stories perhaps in an onload:
function init() {
stories = { "start": new StoryCard("Some stuff", "getup", "sleep")
, "getup": new StoryCard("Something happened", "do this", "do that")
, "sleep": new StoryCard("something else happened", "do something", "do something else")
};
displayStory(stories["start"]);
}

javascript is will not run

I am trying to create a simple vote/poll program with javascript, I have tried to run it on xammp to see if it needed to be executed on a web server with no success. Do I need to include any script js files apart from vote.js like jquery or something? I am not sure.
Can someone help Thanks.

function updateProgressBars()

var pct = Math.round((voting / totalVotes) * 100);

$this.find('progressbar').progressbar({value: pct});
$this.find('.score').html(voting + ' of ' + totalVotes + ' (' + pct + '%)');
});
}

You only close html tag, didin't open tag
