JavaScript: Output

Example: Simple Output and Math in JavaScript


	<!DOCTYPE html>
	<html lang="en">
	<head>
		<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
		<title>JavaScript Example</title>
	</head>

	<body>
		
		<script>
			document.write("<p>Sample JavaScript Program</p>");
			document.write("<p>" + 2 * 4 + "</p>");
		</script>
		
	</body>
	</html>
	

Output:

  Sample JavaScript Program
  8


In the next Javascript examples, we will simply show the code within the HTML body tags (and not the HTML DocType, etc.).

	<body>
		<button type="button" onclick="document.write(2 * 3)">Compute</button>
	</body>
	

Run It

	<body>
		<button onclick="alert('Welcome to my JavaScript Program');">Click Me</button>
