<span class="versionAdded">version added: <a href="/category/version/1.5/">1.5</a></span>deferred.fail( failCallbacks [, failCallbacks] )</h4>
<p class="arguement"><strong>failCallbacks</strong>
A function, or array of functions, that are called when the Deferred is rejected.
</p>
<p class="arguement"><strong>failCallbacks</strong>
Optional additional functions, or arrays of functions, that are called when the Deferred is rejected.
</p>
</li></ul>
<div class="longdesc"><p>The <code>deferred.fail()</code> method accepts one or more arguments, all of which can be either a single function or an array of functions. When the Deferred is rejected, the failCallbacks are called. Callbacks are executed in the order they were added. Since <code>deferred.fail()</code> returns the deferred object, other methods of the deferred object can be chained to this one, including additional <code>deferred.fail()</code> methods. The failCallbacks are executed using the arguments provided to the <a href="deferred.reject"><code>deferred.reject()</code></a> or <a href="deferred.rejectWith"><code>deferred.rejectWith()</code></a> method call in the order they were added. For more information, see the documentation for <a href="/category/deferred-object/">Deferred object</a>.</p></div>
<h3>Example:</h3>
<div class="entry-examples" id="entry-examples"><div id="example-0">
<h4><span class="desc">Since the jQuery.get method returns a jqXHR object, which is derived from a Deferred, you can attach a success and failure callback using the deferred.done() and deferred.fail() methods.</span></h4>
<pre class="prettyprint"><code class="example">
$.get("test.php")
.done(function(){ alert("$.get succeeded"); })
.fail(function(){ alert("$.get failed!"); });
