title: An object of array must contain specific members/names
body: <p>How can i validate an object of arrays that's passed as a parameter to my jQuery plugin to make sure it contains specific members/names?</p>
  
  <p>For example, I want to validate if this object below has 'name', 'ID' &amp; 'Location', all three members, which in this case should be true.</p>
  
  <pre><code>var arr = [{
      name: 'Johny',
      ID: 1,
      Location: 'USA'
  }, {
      name: 'Mike',
      ID: 4,
      Location: 'CAN'
  }];
  </code></pre>
  
  <p>Thanks in advance.</p>
