<desc>
A function that is called when the Deferred is rejected.

</argument>
</signature>
<desc>Add handlers to be called when the Deferred object is rejected. </desc>

<longdesc>
<p><code>deferred.catch( fn )</code> is an alias to <a href="/deferred.then/"><code>deferred.then( null, fn )</code></a>. Read its page for more information.</p>
</longdesc>
<example>
<desc>Since the <a href="/jQuery.get/"><code>jQuery.get</code></a> method returns a jqXHR object, which is derived from a Deferred object, we can rejection handlers using the <code>.catch</code> method.</desc>
<code><![CDATA[
$.get( "test.php" )
.then( function() {
alert( "$.get succeeded" );
} )
.catch( function() {
alert( "$.get failed!" );
} );
