I am new to Javascript (and programming in general) and have been trying to get a basic grasp on working with the DOM. Apologies if this is a very basic mistake, but I looked around and couldn't find an answer.
I am trying to use the appendChild method to add a heading and some paragraph text into the in the very basic HTML file below.
<html>
<head>
<title>JS Practice</title>
</head>
<body>
<script src=script.js></script>
<div id = main>
<h1>Simple HTML Page</h1>
<p>This is a very simple HTML page.</p>
<p>It's about as basic as they come. It has: </p>
<ul>
<li>An H1 Tag</li>
<li>Two paragraphs</li>
<li>An unordered list</li>
</ul>
</div>
<div id=javascript>
</div>
</body>
</html>
Here is the js code:
var newHeading = document.createElement(h1);
var newParagraph = document.createElement(p);
newHeading.innerHTML = New Heading!;
newParagraph.innerHTML = Some text for a paragraph.;
document.getElementById(javascript).appendChild(newHeading);
document.getElementById(javascript).appendChild(newParagraph);
Running it causes an error: Cannot call method 'appendChild' of null
Help? I can't figure out why this isn't working...
