如何将XML解析后的对象保存到JavaScript中

$.ajax({
  type: "GET",
  url: "books.xml",
  dataType: "xml",
  success: function(xml) {
    var xmlDoc = $.parseXML(xml),
      $xml = $(xmlDoc),
      books = [];
 
    $xml.find("book").each(function() {
      var book = {
        name: $(this).find("name").text(),
        author: $(this).find("author").text(),
        price: $(this).find("price").text()
      };
      books.push(book);
    });
    console.log(books);
  }
});
