It is recommended for any web application to be declared as a true ''DOCTYPE''. This can easily be done by using the HTML 5 ''DOCTYPE'' as seen below.

Most current browsers will render content that is declared with this DOCTYPE in "standards mode" which means that your application should be more cross-browser compliant. The ''DOCTYPE'' is also designed to degrade gracefully; browsers that don't understand it will ignore it, and use "quirks mode" to display their content.

Note that some CSS that works within quirks mode is not valid in standards mode. In specific, all percentage-based sizes must inherit from parent block elements, and if any of those ancestors fail to specify a size, they are assumed to be sized at 0 x 0 pixels. For that reason, the '''<style>''' rule was added in the above source code. <!--<ref>[https://developers.google.com/maps/documentation/javascript/tutorial#HTML5 "Declaring Your Application as HTML 5"], [https://developers.google.com/maps/documentation/javascript/ "Google Maps API Javascript v3"].

Introduction

The XBio:D Javascript library offers the functionality to create rich, dynamic, and interactive features for use with the OJ_Break API. The OJ_Break API provides procedures to retrieve data within the xBio:D database, and the xBio:D JS library is how that data gets presented. Users planning on working with the xBio:D JS library should be familiar with Javascript programming and object-oriented programming.

API Access

All functionality in the xBio:D JS library depends on access of data from the OJ_Break API. See OJ_Break API Access for an overview of the API and how to obtain an API access key.

Example

An easy way to become familiar with the xBio:D JS library is to see a simple example involving two web applications. The first is a Google Maps widget which takes data from the OJ_Break method getLocalities for a specified tnuid and displays the data onto an interactive map. Read more about the Google Maps Javascript API here. The second application used in the example is a listing of included taxa for a specified tnuid by using the OJ_Break method getIncludedTaxa (be patient for this method to load). 

  <!DOCTYPE HTML>
   <html>
   <head>
	<meta charset="UTF-8"/>
	<title>xBio:D API test</title>
	<link rel="stylesheet" type="text/css" href="xbiod.css">
	<script  type="text/javascript" 
		src="http://ajax.googleapis.com/ajax/libs/jquery/1.8/jquery.min.js"
	</script>
	<script type="text/javascript" 
		src="https://maps.googleapis.com/maps/api/js?sensor=false"
	</script>
	<script  type="text/javascript" src="xbiod.js"></script>
	<script>
		// Call the loader for the current page
		$(document).ready(loader);

		function loader() {

			// Initialize xBio:D library
			xbiod.init(['visual','taxon'], '{API_KEY}', function() {
				var tnuid = 605;

				// Load xBio:D components
				var visual = new xbiod.visual();
				var taxon = new xbiod.taxon();
		
				// Load map
				visual.showGoogleMap('map_id', tnuid);
		
				// Load included taxa
				taxon.showIncludedTaxa('included_id', tnuid, {show_num_spms: 'Y',
    taxonFormat: '<a href="test.html?tnuid=%tnuid%">%taxon%</a> %author% - %num_spms%'
				});
			});
		}
	</script>
        <style  type="text/css"
		html { height: 100% }
		body { height: 100%; margin: 0; padding: 0 }
		#map_id { height: 50% }
		#included_id { height: 50% }
        </style>
    </head>
    <body>
	<div id="map_id"/>
	<div id="included_id"/>
    </body>
    </html>

View simple example here (test.html)

There are a few things to note about this example:

  • The <!DOCTYPE html> tag is necessary for HTML 5 applications (line 1)
  • Jquery 1.8 library is included with a <script> tag (line 7 - 9)
  • The Map API Javascript is included with a <script> tag (line 10 - 12)
  • The xBio:D JS library is included with a <script> tag (line 13)
  • In the <body> there are two <div> elements which create areas to hold the widgets. The first is called map_id and the second is included_id. (line 40 - 41)
  • Two objects where created to access the xBio:D components called visual and taxon (line 25 - 26)
  • The applications are created by calling there respective methods via the xBio:D library components (line 29 & 32 - 33)

These steps will be explained below.

Declaring Application as HTML 5

It is recommended for any web application to be declared as a true DOCTYPE. This can easily be done by using the HTML 5 DOCTYPE as seen below. Please refer to the Google Maps Documentation on HTML 5 for more info. 


<!DOCTYPE html>
