title: How to check if all inputs are not empty with jQuery
body: <p>I need to validate a form with jQuery. I can check all my inputs one by one, but it's not a very practical solution.</p>
  
  <p>How can i check if all my inputs are non-empty more efficiently? In my form i can have <code>input</code> elements of different types: text, several groups of radio, select etc.</p>
