Welcome
- Introduction 1 - 2 - 3
- First Program
Here is a single JavaScript statement,
which creates a pop-up dialog saying "Hello World!":
alert("Hello World!");
For the browser to execute the statement, it must be
placed inside a <script> element. This element describes which
section of the HTML code contains executable code, and will be described in
further detail later.
<script
type="text/javascript">
alert("Hello World!
");
</script>
The <script> element should then be nested inside the <head> element of an HTML document. Assuming the page is viewed in a browser
that has JavaScript enabled, the browser will execute (carry out) the statement
as the page is loading.
<!DOCTYPE
html>
<html
lang="en">
<head>
<title>Some Page</title>
<script
type="text/javascript">
alert("Hello World!");
</script>
</head>
<body>
<p>The content of the web
page.</p>
</body>
</html>
This basic hello world program can then be used as a
starting point for any new programs that you need to create.
