  92. <p class="information">Jtalk is a young piece of code and evolves quickly. Some features are still incomplete and you may very well encounter bugs.</p>
  93. <p>Jtalk is an implementation of the Smalltalk-80 language. It allows developers to write client-side heavy web applications in Smalltalk. Jtalk includes an integrated development environment with a class browser, workspace and transcript.</p>
  94. <p>Jtalk includes the following features:</p>
  95. <ol>
  96. <li>It is semantically and syntaxically equivalent to <a href="http://www.pharo-project.org">Pharo Smalltalk</a> (the implementation considered as the reference)</li>
  97. <li>It is written in itself and compiles into efficient JavaScript</li>
  98. <li>A canvas API similar to <a href="http://www.seaside.st">Seaside</a> to generate HTML</li>
  99. <li>A <a href="http://www.jquery.com">jQuery</a> binding</li>
  100. </ol>

  102. <h3 id="counter-example">3. The counter example <a href="#counter-example">&para;</a></h3>
  103. <p>The following example is the traditional Seaside-like multi-counter application. The buttons at the bottom of each counter increase or decrease the counter.</p>
  104. <div id="counters"></div>
  105. <script type="text/javascript">
  106. jQuery(document).ready(function() {'#counters'._asJQuery()._append_(smalltalk.Counter._new())._append_(smalltalk.Counter._new())});
  107. </script>
  108. <p>Open a <button onclick="smalltalk.Browser._openOn_(smalltalk.Counter);">browser</button> on the <code>Counter</code> class in the <code>Canvas</code> class category.
  109. <p>Each Jtalk widget is a subclass of <code>Widget</code>. A widget is a graphical component. The <code>#renderOn:</code> method is used to generate HTML using the HTML canvas.</p>
