title: How to get, set and select elements with data attributes?
body: <p>I'm having some trouble with data-attributes, I can't get anything to work for some reason so I must be doing something wrong:</p>
  
  <p>Set:</p>
  
  <pre><code>$('#element').data('data1', '1'); //Actually in my case the data is been added manually 
  </code></pre>
  
  <p>Does that make a difference?</p>
  
  <p>Get:</p>
  
  <pre><code>$('#element').data('data1');
  </code></pre>
  
  <p>Select:</p>
  
  <pre><code>$('#element[data1 = 1]')
  </code></pre>
  
  <p>None of this works for me, am I making this up or how is it?</p>
