使用Edmunds API（edmunds.mashery.io），我试图解析一个汽车对象。
正如您所看到的，JSON Response已完全格式化为以下嵌套树：
Make（id，name，models） - ＆gt;模特（id，name，nicename，styles） - ＆gt;样式
考虑到这一点，请考虑以下API响应：
{
"name": "BMW",
"model": [
{
"id": "BMW_2_Series",
"name": "2 Series",
"nicename": "2-series",
"styles": [
{
"id": 200744428,
"name": "228i 2dr Coupe (2.0L 4cyl Turbo 6M)",

},

"submodelbody": "Coupe",
"submodelname": "2 Series Coupe",
"submodelnicename": "coupe",

"mpgcity": "23",
"categoriesmarket": "Luxury,Performance",
"epaclass": "Subcompact Cars",
"vehiclesize": "Compact",
"crossover": "NA",
"primarybodytype": "Car"
}]},
{
"id": "BMW_3_Series",
"name": "3 Series",
"nicename": "3-series",
"styles": [
{
"id": 200729833,
"name": "320i 4dr Sedan (2.0L 4cyl Turbo 8A)",
"drivenwheels": "rear wheel drive",
"numofdoors": 4,
"manufacturercode": "16TI",
"engine": 200741606,
"transmission": 200741614,
"trim": "320i",
"pricebasemsrp": "33150.0",
"pricebaseinvoice": "31000.0",
"pricedeliverycharges": "995.0",
"submodelbody": "Sedan",
"submodelname": "3 Series Sedan",
"submodelnicename": "sedan",
"mpghighway": "36",
"mpgcity": "24",
"categoriesmarket": "Luxury",
"epaclass": "Compact Cars",
"vehiclesize": "Midsize",
"crossover": "NA",
"primarybodytype": "Car"
}
}
}
使用JQuery＆＃39; ajax，我可以加载JSON响应。我正在尝试基于Model的id创建动态按钮（每个模型都是一个盒装容器，其中包含有关从此响应中填充的模型的信息。
我目前的问题是，当我尝试迭代JQuery的时候，我得到：
关键：模型
value：[Object] [Object] ... [Object]
我想要完成的是以动态方式访问对象的内容并填充以填充它。
除了这个问题的范围之外，我还有一个基于BIG图片的更一般的问题：
使用Edmund的API我计划使用按钮制作汽车选择网站，其中：
状态1：填充，当选择make时，进入状态2
状态2：模型按钮从JSON API填充，移至状态3.
这是我当前的jQuery函数：
$.getJSON('http://127.0.0.1:8000/makes/200000081.json', function( models ) {
console.log(models.model[0].name)
});
这是我的输出：
2系列
如果我将模型[0]更改为模型[3]，结果会发生变化（应该如此）。 如何在我可以使用HTML操作的数组中获取model [x] .name？

也许这样的事情会有所帮助。

我正在寻找这样的代码段：
$.getJSON('http://127.0.0.1:8000/makes/' + make_id + '.json', function( models ) {
$(models.model).each(function(){
console.log(this.name + ' ' + this.id)
});
