How to get a Value from NodeList?

Question

I use document.getElementsByName("phone") to get this NodeList (2). How can i get the value from a special key from List 0? Can i extend the document.getElementsByName to get the value for example for [0].dafaultValue ?

NodeList example

Answer 1

One way to access the items returned from getElementsByNodeName is from W3 Schools:

const collection = document.getElementsByName("phone");
for (let i = 0; i < collection.length; i++) {
  let valueYouAreInterestedIn = collection[i].specialKeyYouWant;
  // Use the value below :)
}
