Background Colour Function

We are going to enhance our background colour script by first turning our inline script into an internal script.

Here we call a function to change the background colour by clicking on a link.

<head>
<script type='text/javascript'>
function changecolour()  {
   document.body.style.backgroundColor='blue';}
</script>
</head>
<body>
<a href="javascript:void(0);" onclick='changecolour();'>Make Me Blue</a>
</body>

Exercise
Create a web page with this code on it.
Now use a parameter in the changecolour() function to allow the user to choose from several different background colors.
