Blaise Nervous Wreck (II) Inmate From: Insane since: Jun 2003	posted 04-27-2004 19:14 Hi guys, it's been a while how ya all doing? I've got a little function that I use to randomise the background image of my body tag (using the class attribute), I've made it only work in IE6 and NS6, (browsers that recognise document.getElementById) code: function golgo13(){ if(document.getElementById){ siteBGs = new Array ( "alpha", "lindisfarne", "quran", "stamp" ); rando = Math.round( Math.random() * (siteBGs.length - 1) ) siteBG = siteBGs[rando]; document.body.className=siteBG; } } This function is simply called with the onLoad event on the body tag, What I would like to know is if there's a similar solution (ie an extension to the code already written) for making it work in earlier browsers, (yes unfortunatly I am talking about NS4). Any comments will be greatly appreciated. Cheers, Blaise

Hi guys, it's been a while how ya all doing?

I've got a little function that I use to randomise the background image of my body tag (using the class attribute), I've made it only work in IE6 and NS6, (browsers that recognise document.getElementById)

code:

function golgo13(){



	if(document.getElementById){

		siteBGs = new Array (

		"alpha",

		"lindisfarne",

		"quran",

		"stamp"

		);



		rando = Math.round( Math.random() * (siteBGs.length - 1) )

		siteBG = siteBGs[rando];

		document.body.className=siteBG;

	}

}

This function is simply called with the onLoad event on the body tag,

What I would like to know is if there's a similar solution (ie an extension to the code already written) for making it work in earlier browsers, (yes unfortunatly I am talking about NS4).

Any comments will be greatly appreciated.

Cheers,

Blaise

Blaise: Couldn't you use SSI or any server side language to set a random value to the class attribute of the BODY tag ?
Otherwise you could do something like :

code:

<html>

<head>



<style type="text/css">



p

{

	margin:0;

}



</style>

<script type="text/javascript">



bodyClasses =

[

    "background-color:orange; font-family:Georgia; color:white;",

    "background-color:red; font-family:'Trebuchet ms'; color:pink;",

    "background-color:navy; font-family:'Times New Roman'; color:gold;"

]



randomIndex = Math.floor( Math.random()*bodyClasses.length)

document.write( '<style type="text/css">body{'+ bodyClasses[randomIndex] +'}</style>' )



</script>



</head>

<body>



<h1>header</h1>

<p>lorem lipsum ...</p>



</body>

</html>

Ok it's slightly different from your initial approach, but it works from NN4.xx to FF0.8

Hope that helps,

That's definately the approach I would take, Poi.

You can still have an external stylesheet, including for the body, just use Javascript (or PHP, or whatever) to generate the background attributes for the body in the head of the document. No need to use a class or an id at all.
