<p>By default, Ext Forms are submitted through Ajax, using an instance of <a href="output/Ext.form.Action.Submit.html" ext:cls="Ext.form.Action.Submit">Ext.form.Action.Submit</a>.
To enable normal browser submission of an Ext Form, use the <a href="output/Ext.form.BasicForm.html#Ext.form.BasicForm-standardSubmit" ext:member="standardSubmit" ext:cls="Ext.form.BasicForm">standardSubmit</a> config option.</p>
<p><b><u>File Uploads</u></b></p>
<p><a href="output/Ext.form.BasicForm.html#Ext.form.BasicForm-fileUpload" ext:member="fileUpload" ext:cls="Ext.form.BasicForm">File uploads</a> 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>&lt;form></tt> element temporarily modified to have its

to a dynamically generated, hidden <tt>&lt;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
"&lt;" as "&amp;lt;", "&amp;" as "&amp;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></div><div class="hr"></div><a id="Ext.form.BasicForm-configs"></a><h2>Config Options</h2><table cellspacing="0" class="member-table"><tbody><tr><th colspan="2" class="sig-header">Config Options</th><th class="msource-header">Defined By</th></tr><tr class="config-row expandable "><td class="micon"><a href="#expand" class="exi">&nbsp;</a></td><td class="sig"><a id="Ext.form.BasicForm-api"></a><b><a href="source/BasicForm.html#cfg-Ext.form.BasicForm-api">api</a></b> : Object<div class="mdesc"><div class="short">If specified load and submit actions will be handled\r

Methods which have been imported by Ext.Direct can be specified here to load and submit
forms.
Such as the following:<pre><code>api: {
    load: App.ss.MyProfile.load,
    submit: App.ss.MyProfile.submit
}</code></pre>
<p>Load actions can use <code><a href="output/Ext.form.BasicForm.html#Ext.form.BasicForm-paramOrder" ext:member="paramOrder" ext:cls="Ext.form.BasicForm">paramOrder</a></code> or <code><a href="output/Ext.form.BasicForm.html#Ext.form.BasicForm-paramsAsHash" ext:member="paramsAsHash" ext:cls="Ext.form.BasicForm">paramsAsHash</a></code>
to customize how the load method is invoked.
Submit actions will always use a standard form submit. The formHandler configuration must
be set on the associated server-side method which has been imported by Ext.Direct</p></div></div></td><td class="msource">BasicForm</td></tr><tr class="config-row expandable "><td class="micon"><a href="#expand" class="exi">&nbsp;</a></td><td class="sig"><a id="Ext.form.BasicForm-baseParams"></a><b><a href="source/BasicForm.html#cfg-Ext.form.BasicForm-baseParams">baseParams</a></b> : Object<div class="mdesc"><div class="short">Parameters to pass with all requests. e.g. baseParams: {id: '123', foo: 'bar'}.\r

<br><p>While <i>some</i> ExtJs Component classes export selected DOM events (e.g. "click", "mouseover" etc), this
is usually only done when extra value can be added. For example the <a href="output/Ext.DataView.html" ext:cls="Ext.DataView">DataView</a>'s
<b><code><a href="output/Ext.DataView.html#Ext.DataView-click" ext:member="click" ext:cls="Ext.DataView">click</a></code></b> event passing the node clicked on. To access DOM
events directly from a Component's HTMLElement, listeners must be added to the <i><a href="output/Ext.Component.html#Ext.Component-getEl" ext:member="getEl" ext:cls="Ext.Component">Element</a></i> after the Component
has been rendered. A plugin can simplify this step:<pre><code><i>// Plugin is configured <b>with</b> a listeners config object.</i>
<i>// The Component is appended to the argument list of all handler functions.</i>

<br>
A delayed, one-time listener.
<pre><code>myDataView.on(<em>'click'</em>, this.onClick, this, {
single: true,
delay: 100

<b>Attaching multiple handlers in 1 call</b><br>
The method also allows for a single argument to be passed which is a config object containing properties
which specify multiple handlers.
