i asked awhile ago and got a function for displaying text however I wish to know the various elements so I can use to it to change things like images or background colors, or anything like that.

<script type="text/javascript">
function describe(text) {
if (document.getElementById) {
document.getElementById('one').innerHTML = text; }
else {
document.all.one.innerHTML = text;
}
}
</script>

.innerHTML works on any tag that has a corresponding closing tag, e.g. <body> (as it also has </body>). It changes the content between the opening and closing tags, so if you have
<span></span>
and change the .innerHTML to "Hello", you get
<span>Hello</span>
It doesn't work on tags without closing tags, however, such as <input>, becase there's no logical place to insert the data in.

There's also a property called .outerHTML which also includes the opening and closing tags; if you have
<span></span>
again and change the .outerHTML to "Hello", you get
Hello

so if i have an image between div tags and then use innerhtml to replace it the image should change?

Yup. But if you're simply going to change the image source... it is probably easier to change whatEverImageObject.src.

yea I just got a javascript book, i have read it before but i'm still bad at javascript. its wierd I know C++.

when doing that it doesnt work heres the code:

function whenload()
{
document.image[0].src="yellow.jpg";
document.image[1].src="red.jpg"
}
function swapimg()
{
document.image[2].src = document.image[0].src;
document.swap.src = document.image[1].src;
document.image[1].src = document.image[2].src;
}
function normal()
{
document.image[2].src = document.swap.src;
document.swap.src = document.image[1].src;
document.image[1].src = document.image[2].src;
}

I believe it should be document.images[0].src :)
