<title>HTML_AJAX 0.5.2 Examples</title>
</head>
<body>
<h1>HTML_AJAX 0.5.2 Examples</h1>
<p>
These are examples showing the basics of using HTML_AJAX
</p>
<p>
These examples show off many of the features of HTML_AJAX, but you'll find them most useful as a learning tool.
Reading through the commented code as you view the examples in your browser.
</p>
<p>
These examples are available online at: http://bluga.net/projects/HTML_AJAX or in your local PEAR install in the documentation dir.
On most Linux systems the location is /usr/share/pear/docs/HTML_AJAX/examples/
You can find the location of your PEAR documentation dir running
<code>pear config-get doc_dir</code>
</p>
<p>The term proxy in these examples refers to a javascript class that is generated and has functions that map to the eqivalent php class.
These proxy classes work much in the same way as a SOAP proxy class that is generated from wsdl.
</p>
<p>
Front end files for examples, you can actually run these and see some example output
</p>
<ul>
<li><a href='proxyless_usage.php'>proxyless_usage.php</a> - Using HTML_AJAX in standalone mode, possible doesn't require PHP or any backend HTML_AJAX classes</li>
<li><a href='proxy_usage_inline_javascript.php'>proxy_usage_inline_javascript.php</a> - Single file proxy style usage</li>
<li><a href='proxy_usage_server.php'>proxy_usage_server.php</a> - Multi-file proxy usage, either server file could be used with this example</li>
<li><a href='queue_usage.php'>queue_usage.php</a> - An example of using a queue to manage ajax calls, a simple live search example</li>
<li><a href='slow_livesearch.php'>slow_livesearch.php</a> - An example showing how the ordered queue can be used to manage high latency</li>

<li><a href='shoutbox.php'>shoutbox.php</a> - How to use AJAX form submission</a></li>
</ul>
<p>
2 server examples are provided, both provide the same output but the auto_server example has code to help you deal with managing multiple ajax classes
</p>
<ul>
<li>server.php - Basic server operation, serving ajax calls and client lib requests</li>
<li>auto_server.php - Advanced server operation, only create php classes as needed</li>
<li><a href='server.php?client=util,main'>server.php?client=util,main</a> - server.php generating a javascript file with the main and util libs in it</li>
<li><a href='auto_server.php?stub=test2'>server.php?stub=test2</a> - auto_server.php generating a javascript file a which contains a generated proxy class for the test2 php class</li>
<li><a href='auto_server.php?stub=all'>server.php?stub=all</a> - auto_server.php generating a javascript file which contains proxies for all the php classes registered with it</li>
</ul>

<strong>This sample is an updated version of the original login sample</strong>:<br />
&#0187; It now uses the new HTML_AJAX_Action class.<br>
&#0187; The initialization of the labels and their input elements is done by Javascript to clean up the page (function: initPage()).<br>
<br>
<strong>Design notes</strong>:<br>
&#0187; The attribute &quot;style.display&quot; cannot be set from php code. Don't know why though. I created a wrapper function for it called &quot;toggleElement&quot; which does the trick. Funny enough when i execute thesame lines of script using -&gt;insertScript nothing happens.<br>
&#0187; You have to add a dummy callback in order to show the loading progress bar.<br>
&#0187; Enter username &quot;peter&quot;, password &quot;gabriel&quot; and any valid e-mail adress to see a messagebox.<br>

* Example of Using HTML_AJAX in proxy operation
*
* All AJAX calls are handled by this same file and the proxy js is outputed in a js block directly in this script
* This is a use case very similar to Sajax (Sajax registers functions not objects)
*
* The only needed interaction is creation of a new object from the proxy defintion, all AJAX calls happen transparently from
*
* If you want to perform async calls a callback object must be passed to the constructor of the object
*
* The client JavaScript library is provided by server.php, you could also copy HTML_AJAX.js (all js files combined) or the seperate js files into your webroot
* from the PEAR data dir and src them directly

/**
* Example of Using HTML_AJAX in proxy operation
*
* All AJAX calls are handled by the auto_server.php file, server.php could also be used, the differences between the two are covered in those files
* This is a use case very similar to JPSpan (JPSpan only has a server.php equivalent)
*
* The only needed interaction is creation of a new object from the proxy defintion, all AJAX calls happen transparently from there
*
* If you want to perform async calls a callback object must be passed to the constructor of the object
*
* The client JavaScript library is provided by auto_server.php, you could also copy HTML_AJAX.js (all js files combined) or the seperate js files into your webroot
* from the PEAR data dir and src them directly. You can use multiple includes of the component files or use the all flag to get them all at once.

This file requires two javascript files to work properly. They are behavior.js and css-Query-p.js and can be found in the js/behaviors folder.
The script allows you to apply behaviors to a css class, so you don't pollute your html with a ton of
inline javascript. The example below uses the following script tag to apply the behaviors.
you can also link external javascript files to apply behaviors as well.
