You can do this to only monitor own properties of the object   var arr        for  var key in p        if  p hasOwnProperty key             arr push p key

You can use this function   function createStringArray arr  prop       var result          for  var i   0  i  lt  arr length  i    1          result push arr i  prop            return result      Just pass the array of objects and the property you need  The script above will work even in old EcmaScript implementations
