- * @class Ext.form.BasicForm
- * @extends Ext.util.Observable
- * <p>Encapsulates the DOM <form> element at the heart of the {@link Ext.form.FormPanel FormPanel} class, and provides
- * input field management, validation, submission, and form loading services.</p>
- * <p>By default, Ext Forms are submitted through Ajax, using an instance of {@link Ext.form.Action.Submit}.
- * To enable normal browser submission of an Ext Form, use the {@link #standardSubmit} config option.</p>
- * <p><b><u>File Uploads</u></b></p>
- * <p>{@link #fileUpload File uploads} are not performed using Ajax submission, that
- * is they are <b>not</b> performed using XMLHttpRequests. Instead the form is submitted in the standard
- * manner with the DOM <tt><form></tt> element temporarily modified to have its
- * <a href="http://www.w3.org/TR/REC-html40/present/frames.html#adef-target">target</a> set to refer
- * to a dynamically generated, hidden <tt><iframe></tt> which is inserted into the document
- * but removed after the return data has been gathered.</p>
- * <p>The server response is parsed by the browser to create the document for the IFRAME. If the
- * server is using JSON to send the return object, then the
- * <a href="http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.17">Content-Type</a> header
- * must be set to "text/html" in order to tell the browser to insert the text unchanged into the document body.</p>
- * <p>Characters which are significant to an HTML parser must be sent as HTML entities, so encode
- * "<" as "&lt;", "&" as "&amp;" etc.</p>
- * <p>The response text is retrieved from the document, and a fake XMLHttpRequest object
- * is created containing a <tt>responseText</tt> property in order to conform to the
- * requirements of event handlers and callbacks.</p>
- * <p>Be aware that file upload packets are sent with the content type <a href="http://www.faqs.org/rfcs/rfc2388.html">multipart/form</a>
- * and some server technologies (notably JEE) may require some custom processing in order to
- * retrieve parameter names and parameter values from the packet content.</p>
