How to Put a JavaScript Into an HTML Page
November 16, 2008 — onggo
<html>
<body>
<script type="text/javascript">
document.write("Hello World!")
</script>
</body>
</html>

The code above will produce this output on an HTML page:
| Hello World! |
Example Explained
To insert a JavaScript into an HTML page, we use the <script> tag (also use the type attribute to define the scripting language).
So, the <script type=”text/javascript”> and </script> tells where the JavaScript starts and ends:
<html>
<body>
<script type="text/javascript">
...
</script>
</body>
</html>
|
The word document.write is a standard JavaScript command for writing output to a page.
By entering the document.write command between the <script type=”text/javascript”> and </script> tags, the browser will recognize it as a JavaScript command and execute the code line. In this case the browser will write Hello World! to the page:
<html>
<body>
<script type="text/javascript">
document.write("Hello World!")
</script>
</body>
</html>
|
Note: If we had not entered the <script> tag, the browser would have treated the document.write(“Hello World!”) command as pure text, and just write the entire line on the page.
