<span class="versionAdded">version added: <a href="/category/version/1.5/">1.5</a></span>deferred.done( doneCallbacks [, doneCallbacks] )</h4>
<p class="arguement"><strong>doneCallbacks</strong>
A function, or array of functions, that are called when the Deferred is resolved.
</p>
<p class="arguement"><strong>doneCallbacks</strong>
Optional additional functions, or arrays of functions, that are called when the Deferred is resolved.
</p>
</li></ul>
<div class="longdesc"><p>The <code>deferred.done()</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 resolved, the doneCallbacks are called. Callbacks are executed in the order they were added. Since <code>deferred.done()</code> returns the deferred object, other methods of the deferred object can be chained to this one, including additional <code>.done()</code> methods. When the Deferred is resolved, doneCallbacks are executed using the arguments provided to the <a href="/deferred.resolve/"><code>resolve</code></a> or <a href="/deferred.resolveWith/"><code>resolveWith</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>
