The following examples use this HTML:
<div id='foo' class='x a'></div> <div id='bar' class='x b'></div>
Query by selector to retrieve a CompositeElement:
var els = Ext.select('.x'); // Act on all elements at once: els.highlight(); // Filter by an additional class: // this will modify the current els CompositeElement els.filter('.b'); // Custom processing: els.each(function(el){ el.id == 'foo' ? el.highlight() : el.frame(); });
