JavaScript How To



The HTML <script> tag is used to insert a JavaScript into an HTML page.



How to Put a JavaScript Into an HTML Page
<html>
<body>
<script language="javascript">
document.write("Hello Everybody!");
</script>

</body>
</html>


The code above will produce this output on an HTML page:

Hello Everybody!




Example Explained
To insert a JavaScript code into an HTML Page, then we use the <script> tag.Inside the <script> tag we use the type attribute to define the scripting language.

So, the <script language="javascript"> and </script> tells where the JavaScript starts and ends:

<html>
<head>
<title>......</title>
</head>
<body>
<script language="javascript">
...Write your Jvascript code hear...
</script>

HTML Statements
</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 tags, the browser will recognize it as a JavaScript command and execute the code line. In this case the browser will write Hello Everybody! to the page:

Note: If we had not entered the <script language="javascript"> and </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.
