title: Wildcards in jQuery attribute's name selector?
body: <p>How can I select all elements which contain data attributes starting with "data-my-" in the following code? <strong>I'm not going to add wildcards to attribute value, It's attribute's name.</strong></p>
  
  <pre><code>&lt;p data-my-data="aa"&gt;foo&lt;/p&gt;
  &lt;p data-my-info="bb"&gt;bar&lt;/p&gt;
  </code></pre>
  
  <p>What I tried and failed:</p>
  
  <pre><code>$("[data-my-*]").addClass("myClass");
  </code></pre>
