Can a JavaScript variable be used in plain HTML?

What I mean is, can a variable/array declared and initialized be used in HTML, outside the <script>-tags? Fx.

<script type=text/javascript>

var foo = array('placeholder1', 'placeholder2');

</script>



<body>

<p><!--access the variable here-->foo[0]</p>

</body>

How do you access the variable/array in this case? like this:

<p><script type=text/javascript>document.print(foo[0])</script></p>

??

Two ways to do this. This is the better one:

<script type=text/javascript>

// make sure to do this onLoad, for example jQuery's $()

var foo = array('placeholder1', 'placeholder2');

document.getElementById(fooHolder).innerHTML = foo.toString();

</script>

...

<p id=fooHolder></p>

Or you could do it this way (which, as Marcel points out, doesn't work in XHTML and really shouldn't be used anyway):

<p><script type=text/javascript>document.write(foo)</script></p>
