Seems obvious but can't find a solution.I have a couple of Div's with the same class and when you hover over them I want to know which one you exactly hovered, as a NodeList Position Value.
HTML
<div id="summary">
<div class="articles"></div>
<div class="articles"></div>
<div class="articles"></div>
<div class="articles"></div>
<div class="articles"></div>
<div class="articles"></div>
<div class="articles"></div>
</div>
JS
let articles = document.querySelectorAll(".articles");
for (let x of articles) {
x.addEventListener('mouseenter', (e) => {
p = Exact Position in Nodelist??
console.log(articles[p]);
});
}
Thank you.
Here is a simple solution I came up with:
let articles = document.querySelectorAll(".articles");
for (let [position, article] of articles.entries()) {
article.addEventListener('mouseenter', (e) => {
console.log(position) // Exact Position in Nodelist
console.log(articles[position]) // The Node hovered
});
}
Hope my help is useful.
You can use mouseover on the parent, this way you will only add one listener:
let articles = document.querySelectorAll(".articles");
var summary = document.getElementById("summary");
summary.addEventListener("mouseover", (e) => {
if (e.target.classList.contains("articles")) {
let position = Array.from(e.target.parentNode.children).indexOf(e.target);
console.log(position,articles[position]);
}
});.articles {
width: 100px;
height: 100px;
border: solid 1px red;
}<div id="summary">
<div class="articles">a</div>
<div class="articles">b</div>
<div class="articles">c</div>
<div class="articles">d</div>
<div class="articles">e</div>
<div class="articles">f</div>
<div class="articles">g</div>
</div>You should take the parent node's children and find its index like below.
Try this
let articles = document.querySelectorAll(".articles");
for (let x of articles) {
x.addEventListener("mouseenter", (e) => {
console.log([...e.target.parentNode.children].indexOf(e.target));
});
}
