<p class="arguement"><strong>url</strong>A string containing the URL to which the request is sent.</p>
<p class="arguement"><strong>success(data, textStatus)</strong>A callback function that is executed if the request succeeds.</p>
</li></ul>
<div class="longdesc">
<p>This is a shorthand Ajax function, which is equivalent to:</p>
<pre>$.ajax({
url: <em>url</em>,
dataType: "script",
success: <em>success</em>
});
</pre>
<p>The callback is passed the returned JavaScript file. This is generally not useful as the script will already have run at this point.</p>
<p>The script is executed in the global context, so it can refer to other variables and use jQuery functions. Included scripts can have some impact on the current page:</p>
<pre>$(".result").html("<p>Lorem ipsum dolor sit amet.</p>");</pre>
<p>Scripts are included and run by referencing the file name:</p>
<pre>$.getScript('ajax/test.js', function(data, textStatus){
console.log(data); //data returned
console.log(textStatus); //success
console.log('Load was performed.');
});</pre>
<p><strong>Note:</strong> Should you require an additional callback for errors when using the <code>getScript()</code> method, the global <code>ajaxError()</code> callback event may be used to achieve this as follows:</p>
<pre>
$( "div.log" ).ajaxError(function(e, jqxhr, settings, exception) {
if (settings.dataType=='script') {
$(this).text( "Triggered ajaxError handler." );
}
});
</pre>
