I made this code, but it wont work. Would be nice if some one can help me. :)
I've tried many things already, but it always didn't worked.
I want it to be so that you press the button and the background gets light, when you press it again it goes back to the origin.
<html>
<head>
<title>test</title>
<style>
.darkerBG {
background: #282828;
}
.lighterBG {
background: white;
}
</style>
</head>
<body class="darkerBG" id="bdbackground">
<script language="javascript" type="text/javascript">
function changeColor()
{
var bdBackground = document.getElementById('bdbackground').class;
if (document.getElementById('bdbackground').class == 'darkerBG')
{
document.getElementById('bdbackground').class == 'lighterBG';
} else if (document.getElementById('bdbackground').class == 'lighterBG')
{
document.getElementById('bdbackground').class = 'darkerBG';
}
}
</script>
<input type="button" class="button" value="test" onclick="changeColor()">
</body>
</html>
