我有以下JSON示例，其中"results"下的数组包含两个对象。它可以在"results"数组下包含数百个具有相同键和不同值的对象。
我没有权限更改此JSON文件。

我有以下代码来获取和显示数组中每个键所需的值，如下所示：

const xmlhttp = new XMLHttpRequest();
xmlhttp.onload = function() {
  const myArr = JSON.parse(this.responseText);

  let text = "";
  for (let i in myArr.results) {
    text += "<div class='fed-reg-container'><h2 class='title'>" + myArr.results[i].title + "</h2><p>" + myArr.results[i].type + "</p><p>" + myArr.results[i].agencies[0].raw_name + " Document # " + myArr.results[i].document_number + "</p><p>Posted on: " + myArr.results[i].publication_date + "</p><p>" + myArr.results[i].abstract + "</p><a class='fed-reg-button' href='" + myArr.results[i].html_url + "'>Read More</a></div>";
  }
  text += "";
  document.getElementById("demo").innerHTML = text;
};
xmlhttp.open(
  "GET",
  "https://www.federalregister.gov/api/v1/documents.json?conditions%5Bagencies%5D%5B%5D=agriculture-department&conditions%5Bagencies%5D%5B%5D=federal-highway-administration&conditions%5Bagencies%5D%5B%5D=fish-and-wildlife-service&conditions%5Bagencies%5D%5B%5D=forest-service&conditions%5Bagencies%5D%5B%5D=interior-department&conditions%5Bagencies%5D%5B%5D=international-boundary-and-water-commission-united-states-and-mexico&conditions%5Bagencies%5D%5B%5D=land-management-bureau&conditions%5Bagencies%5D%5B%5D=national-highway-traffic-safety-administration&conditions%5Bagencies%5D%5B%5D=national-park-service&conditions%5Bagencies%5D%5B%5D=reclamation-bureau&conditions%5Bagencies%5D%5B%5D=environmental-protection-agency&conditions%5Bagencies%5D%5B%5D=council-on-environmental-quality&conditions%5Bagencies%5D%5B%5D=safety-and-environmental-enforcement-bureau&conditions%5Bagencies%5D%5B%5D=environment-office-energy-department&conditions%5Bcomment_date%5D%5Bgte%5D=05%2F01%2F2023&conditions%5Bcomment_date%5D%5Blte%5D=01%2F01%2F2050&conditions%5Bterm%5D=arizona&conditions%5Btype%5D%5B%5D=RULE&conditions%5Btype%5D%5B%5D=PRORULE&conditions%5Btype%5D%5B%5D=NOTICE",

xmlhttp.send();

  text-decoration: none;
}

一切都很好，除了一件事。
正如你所看到的，我的json在"agencies"下有一个嵌套数组，里面有多个对象。
我尝试使用索引来获取每个对象的raw_name下的每个值。
如果我使用+ myArr.results[i].agencies[0].raw_name，它适用于单个对象。可能是[0]或[1]。
当我试图抓取第二个值时，如+ myArr.results[i].agencies[0].raw_name + " - " + myArr.results[i].agencies[1].raw_name，它会破坏整个代码。我没有得到任何回报。只有一张白色。
知道我哪里做错了吗
谢谢！
