<h4 class="name">
<span class="versionAdded">version added: <a href="/category/version/1.1/">1.1</a></span>jQuery.ajaxSetup( options )</h4>
<p class="arguement"><strong>options</strong>A set of key/value pairs that configure the default Ajax request. All options are optional. </p>
</li></ul>
<div class="longdesc">
<p>For details on the settings available for <code>$.ajaxSetup()</code>, see <code><a href="/jQuery.ajax">$.ajax()</a></code>. </p>
<p>All subsequent Ajax calls using any function will use the new settings, unless overridden by the individual calls, until the next invocation of <code>$.ajaxSetup()</code>.</p>
<p>For example, the following sets a default for the <code>url</code> parameter before pinging the server repeatedly:</p>
<pre>$.ajaxSetup({
url: 'ping.php'
});</pre>
<p>Now each time an Ajax request is made, the "ping.php" URL will be used automatically:</p>
<pre>$.ajax({
// url not set here; uses ping.php
data: {'name': 'Dan'}
});</pre>
<blockquote><p>Note: Global callback functions should be set with their respective global Ajax event handler methods—<code><a href="/ajaxStart">.ajaxStart()</a></code>, <code><a href="/ajaxStop">.ajaxStop()</a></code>, <code><a href="/ajaxComplete">.ajaxComplete()</a></code>, <code><a href="/ajaxError">.ajaxError()</a></code>, <code><a href="/ajaxSuccess">.ajaxSuccess()</a></code>, <code><a href="/ajaxSend">.ajaxSend()</a></code>—rather than within the <code>options</code> object for <code>$.ajaxSetup()</code>.</p></blockquote>

<h3>Example:</h3>
<div class="entry-examples" id="entry-examples"><div id="example-0">
<h4><span class="desc">Sets the defaults for Ajax requests to the url "/xmlhttp/", disables global handlers and uses POST instead of GET. The following Ajax requests then sends some data without having to set anything else.</span></h4>
<pre class="prettyprint"><code class="example">$.ajaxSetup({
url: "/xmlhttp/",
global: false,
type: "POST"
});
$.ajax({ data: myData });</code></pre>
