Brand new to web development.
I was following this tutorial: https://www.youtube.com/watch?v=cVyhH3t49fs
Having trouble getting the at the end of index.html to function properly, despite having copied it exactly (my 'images' folder is called 'imgs' instead). Specifically, nothing happens when I click on the numbered buttons to swap images in the gallery.

Any help would be apprecaited. Thanks!
I was reading you code and find the mistake. You write 'length' wrong in the loop. Here how te right code looks like:
for (let i = 0; i < btn.length; i++) {
btn[i].onclick = function () {
gallery.src = imgs[i];
let current = document.getElementsByClassName('active');
current[0].className = current[0].className.replace('active', '');
this.className += 'active';
};
}
I'm doing a memory and got a problem when turning cards. After turning two cards, when I turn a third one, I want the 2 previous cards to be turned again, but for some reason sometimes it works and sometimes only the first of the two cards turned turns. Any idea why this is happening?
JAVASCRIPT (where I think there's the problem):
var cartas = [];
var cartasGiradas = [];
var parejas= 0;
function cambiar_clase(){
cartasGiradas = document.getElementsByClassName("flip-container clicked");
if(cartasGiradas.length==2){
for (var i = 0; i <= cartasGiradas.length; i++) {
cartasGiradas[i].className="flip-container";
this.classList.add("clicked");}
}else if(cartasGiradas.length < 2){
this.classList.add("clicked");
}
}
function inicializar(){
cartas = document.getElementsByClassName("flip-container");
for(var i = 0; i < cartas.length; i++){
document.getElementById("a_girar"+i).addEventListener( 'click', cambiar_clase());
}
}
The HTML source:
<html>
<head>
<script type="text/javascript" src="javascript_memory.js"></script>
<link rel="stylesheet" type="text/css" href="css_memory.css">

Hope somebody can help and sorry if my english is bad, goodbye!
This is the site in question: driglight.com/Learn5.html
The purpose of this site is to click the audio and then choose which image you believe to be the correct representation of the note that was played.
I want to randomize the audio and answers every time the page is refreshed.
When the audio is randomized I need to make sure that the audio that is chosen has it's matching correct answer of an image also chosen and placed randomly among the answers. Also,when any possible answer image is clicked, a div will appear that says 'Good Job!' or 'incorrect'. So when the correct answer is randomized it will need to have the 'Good Job' div to follow it.
Here is the code in html:

I assume every audio fragment will have an image? So with that in mind, you create a random index to select an audio fragment (which you already do). Why don't you store that index in a variable and associate the image fragment with it?
Another option would be to create an object. So you make your array with audiofragments and then you initialize a new JS object, and assign the names of the images to 'properties' with your audiofragment as key. Like this:
var images = {};
images[audioname] = image-name;
***Do this for each audiofragment of course***
That way you can just ask the image from your images-object, using the property audioname.
When the page renders, place some value inside the attributes for the images or div:
<img id=myimage data-audio-file="xyz123.mp3" src="...." />
<div data-audio-file="xyz123.mp3" src="...." >My Content</div>
Read the attribute out when it's time to take some action:
var correctFile = $('#myimage').attr("data-audio-file");
Let's say I have an HTML structure like this:
<li id="jkl">
<div class="aa">
<div class="bb">
<div class="cc">
<div class="dd">
<a ...><strong>
<!-- google_ad_section_start(weight=ignore) -->Test
<!-- google_ad_section_end --></strong></a>
</div>
</div>
</div>
<div class="ee">
<div class="ff">
<div class="gg">
<div class="excludethis">
<a...>Peter</a>
</div>
</div>
</div>
</div>
</div>
</li>
My goal is to set the content(innerhtml) of <li id="jkl"> to '' if inside of <li id="jkl"> there is any word of a list of words(In the example below, Wortliste) except when they are in <div class="excludethis">.
In other words, ignore <div class="excludethis"> in the checking process and show the html even if within <div class="excludethis"> there are one or more words of the word list.
What to change?
My current approach(that does not check for <div class="excludethis">)
Wortliste=['Test','Whatever'];
TagListe=document.selectNodes("//li[starts-with(#id,'jk')]");
for (var Durchgehen=TagListe.length-1; Durchgehen>=0; Durchgehen--)
{
if (IstVorhanden(TagListe[Durchgehen].innerHTML, Wortliste))
{
TagListe[Durchgehen].innerHTML = '';
}
}
with
function IstVorhanden(TagListeElement, Wortliste)
{
for(var Durchgehen = Wortliste.length - 1; Durchgehen>=0; Durchgehen--)
{
if(TagListeElement.indexOf(Wortliste[Durchgehen]) != -1)
return true;
}
return false;
}
Only has to work in opera as it's an userscript.
when i press any key i need to display first div "d1" others hide and i press any key again it display secound div "d2" others hide and press any key again it display third div "d3" others hide ..till six div..not repeating the process again.

<img src="images/d6.jpg" />
</div>
when i press any key i need to display 1st div then i press any key display 2nd div..till 6th div..
how to do it in javascript?
<html>
<head>
<style type="text/css">
.Div
{
display: none;
}
</style>
<script type="text/javascript">
var i = 0;
function KeyHandler() {
i++;
var divs = document.getElementsByClassName("Div");
for (var div = 0; div < divs.length - 1; div++) {
divs[div].style.display = 'none';
}
var ele = document.getElementById("d" + i);
ele.style.display = "block";
}
</script>
</head>
<body onkeyup="KeyHandler()">
Press any key..
<div id="d1" class="Div">
<h5>
Div1</h5>
</div>
<div id="d2" class="Div">
<h5>
Div2</h5>
</div>
<div id="d3" class="Div">
<h5>
Div3</h5>
</div>
<div id="d4" class="Div">
<h5>
Div4</h5>
</div>
<div id="d5" class="Div">
<h5>
Div5</h5>
</div>
<div id="d6" class="Div">
<h5>
Div6</h5>
</div>
</body>
</html>
Try this out
var currentVisible = 0;
document.onkeyup = function() {
// First hide all by class 'objects'
// Requires IE9+ FF3+, others are supported
var objs = document.getElementsByClassName('objects');
for (var i=0; i<objs.length; i++) {
objs[i].style.display = 'none';
}
// Show the one we are supposed to show
if (++currentVisible == 7)
currentVisible = 1;
var el = document.getElementById('d' + currentVisible);
el.style.display = 'block';
}
100% untested tho, since I have no access to any fiddle atm.
