<html>
<head>
<title>Test Page</title>
</head>
<body>
<script type="text/javascript">
function testFunction(element)
{
alert(element.id);
}
</script>
</body>
</html>This inevitably creates grief when trying to debug script code, and also makes it harder to find javascript code when a new developer starts working on your application. On top of all that, maintenance starts becoming an issue.
A better example would be to separate javascript code from your web page:
// javascript file testJavascript.js
function testFunction(element)
{
alert(element.id);
}
<!-- html file testHtml.html -->
<html>
<head>
<title>Test Page</title>
</head>
<body>
<script type="text/javascript" src="include/testJavascript.js"></script>
</body>
</html>
