How to iterate a NodeList and attach an event listener to each element
You can add an event listener to all the elements returned by a document.querySelectorAll()
call by iterating over those results using the for..of
loop:
const buttons = document.querySelectorAll("#select .button")
for (const button of buttons) {
button.addEventListener('click', function(event) {
//...
})
}
It’s important to note that document.querySelectorAll()
does not return an array, but a NodeList object.
You can iterate it with forEach
or for..of
, or you can transform it to an array with Array.from()
if you want.
