我需要通过api从一些租赁软件生成的json格式的选定数据创建一个表。提供的json数据是一个产品列表，其中包含大量包含其他对象和数组的对象

当我需要从对象中的对象检索数据时，问题就出现了。我想从下面的数据中得到姓名、重量和租金。租金价格在租金率对象中

下面是我用来获取数据的JS：

$(document).ready( function() {
$.getJSON( 'https://myapi.com/products', function(data) { 
  $.each(data.products, function() { 
     $("table#prod").append("<tr><td>" + this['name'] + "</td><td>" + this['rental_rate.price'] + "</td><td>" + this['weight'] + "kg</td></tr>");
  }); }); });

$（文档）.ready（函数（）{
$.getJSON（'https://myapi.com/products，函数（数据）{
$.each（data.products，function（）{
$（“table#prod”）。追加（“+此['name']+”“+此['rental#u rate.price']+”“+此['weight']+“kg”）；
}); }); });
这在名字和重量上都很好，但不是租金。我已经在互联网上的大多数地方做了彻底的搜索，但没有找到答案——我的javascript知识有限，这可能意味着我在这方面完全错了，或者描述得不够好。。。
任何帮助或改进方法都将不胜感激
