1.9 to 1.10

  • Upgraded jQuery from 1.4.2 to 1.7.1
    • In many cases you will need to replace .attr() with .prop() in your js code: 'As of jQuery 1.6, the .attr() method returns undefined for attributes that have not been set. In addition, .attr() should not be used on plain objects, arrays, the window, or the document. To retrieve and change DOM properties, use the .prop() method.' http://api.jquery.com/attr/
