I'm currently trying to create a spelling quiz as part of a project website using HTML, CSS and JScript.
The concept is: the user is shown a word with two letters missing (shown by the underscores). They then select which answer is right (the three button options) and an alert message should come back on the window to say if they are correct or incorrect.
My idea behind the code I wrote so far was to have an event listener on the button that when clicked would trigger the alert either saying correct or incorrect if I have programmed it to be so.
My code isn't working, could anyone help me?
var aChoice = document.getElementById("S1");
aChoice.addEventLister("Click", C1)
function C1 ()
{
alert("Correct");
}

(More code I was intending to write on Javascript here for logic purposes.)
var bChoice = document.getElementById("S2");
bChoice.addEventLister("Click", C2)
function C2 ()
{
alert("Incorrect");
}
var cChoice = document.getElementById("S3");
cChoice.addEventLister("Click", C2)
function C2 ()
{
alert("Incorrect");
}
1.You cannot have more than one id="S1"! Since the id attribute is unique for the entire html document. In your case, it is better to use the class. Since there may be more buttons with answer options, like this:
<label class="Albl">Answer:
<button class="btn">a i</button>
<button class="btn">i a</button>
<button class="btn">e i</button>
</label>
2.Now on js ... I corrected your code. Also, you need to change the method of accessing elements (buttons). Like this:
var aChoice = document.querySelector(".btn");
3.Now everything is ready, but not completely! You need the logic for determining the correctness of the choice of the option by buttons.
var aChoice = document.querySelectorAll(".btn");
aChoice.forEach(function(aChoice_current, index) {
aChoice_current.addEventListener('click', function(){
if (index == 0) {
console.log('The answer is correct! :)');
} else {
console.log('The answer is not correct! :(');
}
})
})

I am trying to find a javascript code for a word searcher in a text (through a form and a search button). Ι have found one which can search many words at the same time, but they need to be in a row. If the words are mixed it doesn't work. What kind of updates should we make?
Please advise
My regards

To search many words mixed
As I don't exactly know what methods you would like to use. I can't fully answer.
But take a look at this js method: https://www.w3schools.com/jsref/jsref_includes.asp
I just started learning JS, and im not understanding it that well. I am not that great at coding generally, so apologies for this really barebones and very possibly wrong website, but all I wanted to accomplish at the moment was to change the websites background color when I press the button. When I did it in <script< it worked, but when I moved it into a separate JS file, it stopped working. The error message I get is: SyntaxError: Unexpected token '}'. Expected an opening '{' at the start of a function body.
Could someone please help? Thank you in advance!

you are assigning both btnRed and the document.getElementById method to a String value 'btnRed' instead of actually running the getElementById method and passing it an argument "btnRed"
so just change the
let btnRed = document.getElementById = ('btnRed'); to
let btnRed = document.getElementById('btnRed');
You need to change the HTML element btn-Red to be btnRed and fix up your JavaScript... try this.
function makeRed() {
let r = document.getElementById('temp')
r.style.backgroundColor = 'lightsalmon';
}
let btnRed = document.getElementById('btnRed');
btnRed.addEventListener("click", makeRed);
body {

Attempting a vanilla js solution to focus .btn-1 by default on page load.
Can't figure out why I keep getting this error : index.js:2 Uncaught TypeError: document.getElementsByClassName(...).focus is not a function at window.onload (index.js:2)
Anyone have thoughts on this please?
index.html :

</html>
index.css :
.btn {
/* background-color: #4caf50; Green */
border: none;
color: white;
padding: 15px 32px;
text-align: center;
text-decoration: none;
display: block;
font-size: 16px;
margin: 1em;
}
.btn:hover {
background-color: grey;
}
.btn:focus {
background-color: blue;
}
index.js :
window.onload = function () {
document.getElementsByClassName('btn-1').focus();
};
The getElementsByClassName returns an array you can do this if you do like this
window.onload = function () {
document.getElementsByClassName('btn-1')[0].focus();
};
or you can use querySelector instead which targets the first element on the document
window.onload = function () {
document.querySelector('.btn-1').focus();
};
Have you tried the autofocus attribute you can give to the button elements.

<button type="button" autofocus>Click Me!</button>
My main.html displays the menu.htm and welcome.htm using frameset. Drop down menu buttons "Admin..." and "Scheduler..." suppose to show dropdown content on mouse hover. Since welcome.htm is on top of menu.htm therefore content of the dropdown button doesn't show up.
However, All menu button work as expected when open the menu.htm as standalone page(see attached pic)menu.htm But drop-down buttons content does not show up when open in main.html using frame tags.

first of all Why not use html5?
You should use iframe instead of frame
https://www.w3schools.com/tags/tryit.asp?filename=tryhtml_iframe
after, you add id to iframe and you add display option or you add "position:absolute;z-index" these iframes with css.
after, then was mouseover in iframe you change z-index option with javascript
I help you but first
Can you review jquery.load()

I think it might be easier for you.

Why doesn't it count styles and write an error, how can I fix it? It seems that he indicated all the paths correctly, connected styles and scripts, but he either does not read them at all (styles) or displays such an error. Here is the code html, javascript, css.
How can you fix this error? And in general not so?

why don't you try to make the tag at the bottom.
like this:
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<link rel="stylesheet" type="text/css" href="style.css">

<a class="cookie_btn" href="#politika">privacy policy</a>
</div>
</div>
<script src = "script.js">
</script>
</body>
</html>
here you go
HTML is read from top to bottom, so the script is called before the rest of the page is rendered.
cookiewin = document.getElementsByClassName('cookie_notice')[0];
This line of code is accessing a element which hasn't loaded yet resulting in undefined. To fix this problem simply place the script tag at right before the closing body tag.
