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 ?
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 :)
}
Please comment if there is anything else you need help with!
