title: Selecting element by data attribute with jQuery
body: <p>Is there an easy and straight-forward method to select elements based on their <code>data</code> attribute?  For example, select all anchors that has data attribute named <code>customerID</code> which has value of <code>22</code>.  </p>
  
  <p>I am kind of hesitant to use <code>rel</code> or other attributes to store such information, but I find it much harder to select an element based on what data is stored in it.</p>
