I am trying to add an event listener to an object(an array of classses) which i populated using queryselectorall in javascript, i want it such that whenever i take my mouse over any of the classes, that particular class changes its color . Youshould also note that the classes were added using appendchild in js

What I have tried:

const selectElemAll = function(className) {
	return document.querySelectorAll(className);
};

let blogContent = selectElemAll(".blog-content-text");

function ReadMore(blogContentClass) {
	let contentRemove = [];
	let elipsis = "...";
	for(var i = 0; i < blogContentClass.length; i++){
		if (blogContentClass[i].innerText.length > 180) {
		let content= blogContentClass[i].innerText;
		let contentRemoveAdd = content.slice(180, content.length);
		 contentRemove.push(contentRemoveAdd);
		 blogContentClass[i].innerText = blogContentClass[i].innerText.replace(contentRemove[i], elipsis);
	    let readMoreBtn = document.createElement("a","HTMLLinkElement");
		 readMoreBtn.className = "read-more";
		 readMoreBtn.innerHTML = "Read More";
		 readMoreBtn.href = "#";
		 readMoreBtn.classList.add("read-more-btn");
		 blogContentClass[i].appendChild(readMoreBtn);
		}
	}
}
	ReadMore(blogContent)

	for(var i = 0; i < blogContent.length; i++){
		blogContent[i].addEventListener('mouseover', () => {
			blogContent[i].childNodes[1].style.color = "black";
		});

Solution 1

Think, having a lookup at this would help: CSS Pseudo-classes[^]
Example:

CSS

a {
  color: green;
}

a:hover {
  color: yellow;
}

button:active {
  background-color: green;
}

button:focus {
  background-color: blue;
}

button:hover {
  background-color: red;
}

When do the :hover, :focus, and :active pseudo-classes apply?[^]

I know there are ways to use CSS to do that but i just prefer using javascript because the element was created using javascript, so i would prefer the styling with javascript

And you don't want to add the class at runtime via javascript?

Ofcourse i would add the class at runtime with js
