Answer 1

Alt 1: Use jquery tabs:
See demo and code here: http://jqueryui.com/demos/tabs/
Alt 2: Hide/show div in same html file:
HTML:
<div id="nav">
Show content 1
Show content 2
Show content 3
</div>
<div id="content1" class="toggle" style="display:none">show the stuff1</div>
<div id="content2" class="toggle" style="display:none">show the stuff2</div>
<div id="content3" class="toggle" style="display:none">show the stuff3</div>
jQuery:
$("#nav a").click(function(e){
e.preventDefault();
$(".toggle").hide();
var toShow = $(this).attr('href');
$(toShow).show();
});

Alt 3: Load from server ondemand:
To load html into your main div you should use: http://api.jquery.com/load/
Follow examples on that site. And be aware that the html side you are loading must be in same domain as you are hosting the new page.
Html
Show content 1
Show content 2
jQuery
$("#nav a").click(function(e){
e.preventDefault();
$('#maindiv').load($(this).attr("href"));
});

Answer 2

Using jQuery, you could do something like this.
This will open the site <a href="example.html"> and put it inside of the <div id="content"> when you click it, and then disable changing the whole site.
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.7.0/jquery.min.js" type="text/javascript"></script>
<script>
$(document).ready(function() {
$('#nav a').click(function(e) {
e.preventDefault();
$('#content').load($(this).attr('href'));
});
});
</script>
<div id="nav">
Some page
Some other page
My page
</div>
<div id="content">
show the stuff
</div>

Answer 3

Something like this:
function setContent(div, content)
{
getElementById(div).innerHtml = content;
return false; // return false to ignore the click
}
a link

Answer 4

to show a hidden div (i think this is what you wanted)
the javascript (using jQuery)
<script src="http://code.jquery.com/jquery-latest.js"></script>
<script type="text/javascript">
$(document).ready(function () {
$("#showdiv").click(function () {
$("#hiddendiv").show();
});
});
<script>
the html
Show the Div
<div id="hiddendiv" style="display:none;">Content here</div>
you can see it in action here
