How can I change the attributes of using class name or id name (for example ".testing a") using javascript?
Edit. I worded the question the wrong way. What I mean is I want to change the css of the a class.
document.querySelector('.testing a').setAttribute('color','green');
Something like above but the above code is not working.
<div class="testing">
<a>1</a>
<a>2</a>
</div>
You can use querySelectorAll() to get all required elements and use forEach() to loop to through elements and change style.color of element
let elms = document.querySelectorAll('.testing a');
elms.forEach(e => e.style.color = "green")
<div class="testing">
<a>1</a>
<a>2</a>
</div>
Using jQuery
$('.testing a').css('color','green');
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="testing">
<a>1</a>
<a>2</a>
</div>

Good day,
I would like to ask how I can get the value from price. Neither of them has a unique id so it makes things hard for a noob like me. Any suggestions? Thanks.
<div class="modal">
<span class="name">$</span>
<span class="price">0.04</span>
<hr style="background: linear-gradient(to right, #ffc82d , #ffff73);">
<div class="weapon" style="background-image: url('assets/img/free_case_item.png');"></div>
</div>
You can do it with pure JavaScript using DOM manipulation.
Assuming you only have one element with the price class: document.getElementsByClassName("price").item(0).innerText.
Ideally you would give it an ID (e.g. price): document.getElementById("price").innerText
You can try with document.querySelector:
var price = document.querySelector("div.modal span.price").innerText
This matches the first <span class="price"> inside <div class="modal">.

Need a jQuery solution of a JavaScript code and more shorter than it is.
Code:
if (event.target.parentElement.parentElement.parentElement.parentElement.getAttribute("class").include("newSearch"))
where event is coming from,
$(document).on('click', '#divCl > #lnkCl', function (event) {
JQuery version : 2.2.4
HTML Code:
<div class"newSearch">
<div>
<div>
<div>
<div id="divCl">
<div id="lnkCl">
</div>
</div>
</div>
</div>
</div>
</div>
This is not the exact code, as we have different use for the divs in between.
Maybe something like this.
$(document).on('click', '#divCl > #lnkCl', function(event) {
if ($(this).parents(".newSearch").length) {
// do your thing
}
});

my solution: https://jsfiddle.net/thecodesalim/dsvgdkks/2/
HTML:
<div id=leaderboard class="panel hidden">
<h1>Leaderboard</h1>
<ol id=top10>
<li>Jyn Erso</li>
<li>Mon Mothma</li>
<li class="me">Han Solo</li>
<li>Galen Erso</li>
<li>Thane Kyrell</li>
<li>Norra Wexley</li>
<li>Ciena Ree</li>
<li>Malakili</li>
<li>R5-D4</li>
</ol>
</div>
JS:
function updateLeaderBoard(arr,me){
let players = document.getElementById("top10");
for(let i =0; i < arr.length;i++){
let li = document.createElement("li");
li.appendChild(document.createTextNode(arr[i]));
players.append(li);
if(arr[i].includes(me)) li.classList.add("me");
}
}
updateLeaderBoard(["Jack","Robo","Simi"],"Robo");
I want the text content to be only the list in javascript, the html list should be replaced.
Thanks
I believe you are saying that the HTML list is a placeholder and you want to clear it out and just insert whatever you want from js? If so, just empty the <ol> when you have selected it:
let players = document.getElementById("top10");
players.innerHTML = "";

In short, what I want to do is make it so when I click a button in my HTML document, I want that button to subsequentely be removed by it's ID, using javascript if possible. I've been searching for a solution with no success, can anyone help me out here?
In your HTML:
<button onclick="deleteSelf(this)">Click me</button>
In your JavaScript:
function deleteSelf(button) {
button.remove();
}
This works:
https://jsfiddle.net/00p4oLfy/
document.getElementById('test').remove();
<p id="test">This is a test</p>
<p id="test2">This is another test</p>
Html
<div>
<button id="ClickMe">Click Me</button>
</div>
Javascript
document.getElementById('ClickMe').remove();
