我需要通过api以json格式的某些出租软件生成的选定数据创建表。所提供的json数据是产品列表，并且与包含其他对象和数组的对象相当广泛。如何从多个对象级别获取json数据
问题出在我需要从对象内的对象中检索数据时。我想从下面的数据中得到名称，重量和租价。租赁价格在rental_rate对象中。

，这里是我使用来获取数据的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>");
}); }); });
这工作正常进行名称和重量，而不是租赁价格。我对互联网上的大多数地方进行了彻底搜索，但没有找到答案 - 我的JavaScript知识有限，这可能意味着我正在进行这种全部错误，或者没有足够好地描述它...... 任何帮助或改进的方法将不胜感激！
你需要'这个[ 'rental_rate'] [ '价格']'或'this.rental_rate [ '价格']'或'this.rental_rate。价格“两分钟的基础研究会产生这些信息。 –
