下划線以使用另一個數組過濾數組對象

Question

如何從數組b獲取特定屬性。 這些要過濾的屬性在數組a中。

有沒有更簡單的方法可以使用下划線。

var a = [{
  name: "code"
}, {
  name: "barcode"
}, { 
  name: "status",
  type: "button"
}];

var b = [{
  id: 1,
  code: 10,
  barcode: "121212",
  status: "success",
  amount: "10",
  available: true
}, {
  id: 1,
  code: 10,
  barcode: "121212",
  status: "success",
  amount: "10",
  available: true
}];

現在，如果使用下划線，我如何得到以下結果

var c = [{
  code: 10,
  barcode: "121212",
  status: "success"
}, {
  code: 10,
  barcode: "121212",
  status: "success"
}];

Answer 1

(function( property, x, y ) {
  var filters = _.pluck( x, property );
  var filter = function( obj ) {
    return _.pick( obj, filters );
  };
  return _.map( y, filter );
})( 'name', a, b );

Answer 2

var filters = _.pluck(a, 'name');

var c = _.map(b, function(el) {
    return _.pick(el, filters);
});
