getElementsByClass and appendChild
just brushing up on my javascript skills and trying to figure out why getElementsByClass isn't working for my code. The code is pretty simple. Upon clicking a button "clicky", the script will create a child h1 element of div. It works perfectly fine when I use getElementById and changing the div class to Id but doesn't work when I change it to class.
I've tried, getElementsByClassName, getElementsByClass, getElementsByTagName and changing the div to the appropriate attribute but no luck.
<!doctype html>
<html>
<body>
<p>Click on button to see how appendChild works</p>
<button onclick="myFunction()">Clicky </button>
<script>
function myFunction(){
var first = document.createElement("H1");
var text = document.createTextNode("Jason is pretty awesome");
first.appendChild(text);
document.getElementsByName("thistime").appendChild(first);
}
</script>
<div class="thistime">Hi</div>
</body>
</html>
Answer
You need to update your code from
document.getElementsByName("thistime").appendChild(first);
to
document.getElementsByClassName("thistime")[0].appendChild(first);
