title: regexp for checking the full name
body: <p>I would like to write a regexp to check if the user inserted at least two words separated by at least one empty space:</p>
  
  <p>Example:</p>
  
  <pre><code>var regexp = new RegExp(/^[a-z,',-]+(\s)[a-z,',-]+$/i);
  
  regexp.test("D'avid Camp-Bel"); // true
  regexp.test("John ---"); // true // but it should be false!
  </code></pre>
