title: Can I query for attribute key wildcards in jQuery?
body: <p>I'd like to select elements with attribute names (keys) that begin with a set string. Use case: the <a href="http://jqueryui.com/demos/dialog/" rel="nofollow">jQuery UI dialog</a> creates buttons whose only unique identifers are a pseudo-random custom attribute with a sequential value such as <code>jQuery1288273859637="40"</code></p>
  
  <p>I'd like to select based on the fact that the attribute's <em>name</em> is jQuery* (begins with jQuery)</p>
