How to get a list of values from a specific CSS Selector

I want to retrieve at once a list of values from a spcific CSS selector.

I want to extract the text in <strong> only. I am using :

document.querySelectorAll("p > strong")

But the I got a Node list...

NodeList(101) [strong, strong, strong, strong, strong, strong, strong, strong, strong,...]

I am targeting the innerText like :

document.querySelectorAll("p > strong")[1].innerText

How can I extract all the targeted text values in a list at once ?

Use the spread operator to turn it into an array and then use the map method to get what you need.

var array = [...document.querySelectorAll("p > strong")].map(a=>a.innerText);

console.log(array);
<p><strong>I</strong></p>
<p><strong>heart</strong></p>
<p><strong>To</strong></p>
<p><strong>Fart</strong></p>

Your code works if you loop over the nodeList you have

I use textContent though - same thing but more standard

const strong = document.querySelectorAll("p > strong")
const texts = []
for (let i = 0; i< strong.length;i++) texts.push(strong[i].textContent)
console.log(texts)
<p>Here is some <strong>text</strong> and some <strong>more text</strong></p>

Alternatively but slower (if that matters) map the nodelist after casting to array using spread syntax

const texts = [...document.querySelectorAll("p > strong")]
  .map(({textContent}) => textContent)
console.log(texts)
<p>Here is some <strong>text</strong> and some <strong>more text</strong></p>

jQuery if you need

const texts = $("p strong").map((_,e) => e.textContent).get();
console.log(texts)
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.6.0/jquery.min.js"></script>
<p>Here is some <strong>text</strong> and some <strong>more text</strong></p>
