I want to know if/how it is possible to make a javascript rollover without the "name" attribute.

e.g.

<img src="blahblah.jpg" alt="lol" name="lol" />

This is due to the "name" attribute not being valid XHTML strict 1.0.

 

My rollover.js code is:

function imageOn(imageName) {
    if (document.images) {
        currentImage = document.images[imageName];
        currentImage.src = "./images/navigation/" + imageName + "2.jpg";
    }
}

function imageOff(imageName) {
    if (document.images) {
        currentImage = document.images[imageName]
        currentImage.src = "./images/navigation/"+ imageName + ".jpg";
    }
}

 

My index.htm code is:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"

Javascript rollovers are unnecessary in these days of CSS. People can turn off Javascript, and sometimes do. People can turn off CSS if they know how, but no one ever does as it doesn't pose a security risk.

 

Use this in your html:

 

<a href="someURL" id="someID" >text to be replaced</a>

 

Then put this in the head of your document:

 

<style type="text/css">
#someID
{
    background-image: url(path/to/image.jpg); //put the url to your 'off' image here
    height: ___px; // set this to the height of the image
    width: ___px; // set this to the width of the image
    text-indent: -9999px; //this will get rid of whatever text you put between <a> and </a>
}
#someID:hover
{
   background-image: url(path/to/image2.jpg); //put the URL to your rollover image here
}
</style>

 

This will work with no javascript, requires less code, and needs no name attribute.

and the stylesheet is:

	text-indent: -9999px;

}

#navabout_us
{
	background-image: url(./images/navigation/about_us.jpg);
	height: 30px;
	width: 120px;

	text-indent: -9999px;

	background-image: url(./images/navigation/portfolio2.jpg);
}

#navdesigns
{
	background-image: url(./images/navigation/designs.jpg);
	height: 30px;
	width: 100px;
	text-indent: -9999px;
}
#navdesigns:hover
{
	background-image: url(./images/navigation/designs2.jpg);
}

#navcontact_us
{
	background-image:url(images/navigation/contact_us.jpg); //put the url to your 'off' image here
	height: 30px; // set this to the height of the image
	width: 188px; // set this to the width of the image
	text-indent: -9999px; //this will get rid of whatever text you put between <a> and </a>
}
#navcontact_us:hover
{
	background-image: url(./images/navigation/contact_us.jpg); //put the URL to your rollover image here
}

 

It doesn't work, the text isn't replaced and the images arn't filling to the correct size
