Ext quick tip .. Ext.query

Here is another example of where you can make easy use of the Ext framework and just scratch the surface ...
With Ext you can use Ext.get( element name/ dom element ) to retrieve an individual element. But what if you want to gather a group of html elements and operate across all of them.
This is where the Ext.query method comes in. Basically this runs a query against the HTML DOM document and finds all elements that match. For example the following would return an array of elements that have the class 'foo'.
Ext.query("*[class*=foo]")
You can find loads of other examples on the Ext website here.
