10,637 Pointserror in code challenge
I have to select two elements in the DOM, using the getElementBy.. methode. It returns me every time an error, can't find it
var fullName = document.getElementById("full_name");
var lastName = document.getElementByClass("last_name");
<!DOCTYPE html>
<html>
<head></head>
<body>
<h1 id="full_name"><span class="first_name">Andrew</span> <span class="last_name">Chalkley</span></h1>
<script src="app.js"></script>
</body>
</html>

Treehouse TeacherHi there! I solved this challenge by using the getElementsByTagName
method. This is what I used:
var lastName = document.getElementsByTagName("span")[1];
This selects the second span in the document by using the index of 1. Hope this clears things up!

I too tried to solve this challenge using getElement* but I got errors. I solved this challenge using
var fullName = document.querySelector("#full_name");
var lastName = document.querySelector(".last_name");
document.querySelector is a modern replacement for document.getElementBy* method.
# gets by id
. gets by class
The challenge hints that you should use getElementByTagName for the last_name but it didn't work for me, so I used querySelector.

10,637 PointsThanks Hannu, I've tried getElementByTagName too, but it didn't work (like you say). I've noticed you have more than 13k points, and you are a member since 31 august 2016. How much do you have practice?:)
