Single Page Site With jQuery

Some websites are simple. Some are so simple they could all just go on one page with a touch of Javascript to show and hide the content pieces. The only trick is to make sure that the URL reflects the currently viewed container, and that when someone bookmarks it or shares a link, Javascript will determine which container to show first. So here’s how you do that.

// Set the current item token, and the on-load token to default		
var current_token = load_token = 'first'; 
$(document).ready(function() { 
	// Get the on-load token from the URL 
	var loc = document.location.href;
	var pound_index = loc.indexOf("#");
	if (pound_index != -1) {
		load_token = loc.substring(pound_index + 1, loc.length);
	}
 
	$('.content').hide(); // Hide everything
	$('#'+load_token).show(); // Show the on-load content
 
	$('.switch').click(function() {
	 	// Get the token to switch to from the link id
		var this_id = $(this).attr('id');
		var underscore_index = this_id.indexOf("_");
		var on = this_id.substring(underscore_index + 1, this_id.length);
		if (current_token != on) { // Only if the user is actually switching
			$('.content').hide(); // Hide everything
			$('#'+on).show(); // Show the desired content
			location.href = '#'+on; // Set the URL so it's bookmarkable
			current_token = on;
		}
	});
});

and if our HTML looks like this:

<div id="nav"> 
	<ul> 
		<li><a href="#first" class='switch' id='top_first'>first</a></li> 
		<li><a href="#second" class='switch' id='top_second'>second</a></li> 
		<li><a href="#third" class='switch' id='top_third'>third</a></li> 
		<li><a href="#fourth" class='switch' id='top_fourth'>fourth</a></li> 
	</ul> 
</div> 
<div id="first" class='content'>one one one</div> 
<div id="second" class='content'>two two two</div> 
<div id="third" class='content'>three three three</div> 
<div id="fourth" class='content'>four four four</div>

We end up with this:


This is content box one.
This is known as content box two.
This little fella goes by content box three.
We don’t talk about content box four.

If you notice, when you click the links, the URL changes. If you refresh that same URL, you will find the same box selected. Nifty, no?
