Get an Element by a Custom Attribute Using JavaScript
To get an element by a custom attribute using JavaScript, we can use the document.querySelector method with a select string with the tag and attribute of the element we’re looking for.
For instance, we can write:
<div data-automation="something">
</div>
to add a div.
Then we write:
const div = document.querySelector("div[data-automation='something']")
console.log(div)
to select the div with document.querySelector.
We just put data-automation='something' in the square brackets to select the element with attribute data-automation with value something.
