javascript - 用js和foreach为元素腾出一段时间

Question

我有一个 json 对象(由服务器返回)，我想用一段时间或 forEach 来显示购物车的产品。 我的对象的名称是response2，它包含购物车的产品。 我想花点时间在表格中显示这样的产品(只是想法):

<div>
<p>${response2.product}</p>
<p>${response2.price}</p>
</div>

抱歉英语不好，编程经验低! 谢谢!

这是该对象的外观:

[  
   {  
      "id":46,
      "email":"rr",
      "product":"Tort Oreo",
      "description":"Detalii: (ex: textul de pe tort, unde sa fie plasate figurinele si in ce numar)",
      "figurina":"",
      "img_tort":"nu exista",
      "price":"299"
   },
   {  
      "id":47,
      "email":"rr",
      "product":"Pizza Nevada",
      "description":"Personalizare pizza",
      "figurina":"",
      "img_tort":"",
      "price":"25"
   },
   {  
      "id":48,
      "email":"rr",
      "product":"Pizza Nevada22",
      "description":"Personalizare pizza",
      "figurina":"",
      "img_tort":"",
      "price":"29"
   }
]

JSON response2 是一个对象数组。

您需要引用数组索引，然后才能调用/访问对象元素。

var response2 = [  
   {  
      "id":46,
      "email":"rr",
      "product":"Tort Oreo",
      "description":"Detalii: (ex: textul de pe tort, unde sa fie plasate figurinele si in ce numar)",
      "figurina":"",
      "img_tort":"nu exista",
      "price":"299"
   },
   {  
      "id":47,
      "email":"rr",
      "product":"Pizza Nevada",
      "description":"Personalizare pizza",
      "figurina":"",
      "img_tort":"",
      "price":"25"
   },
   {  
      "id":48,
      "email":"rr",
      "product":"Pizza Nevada22",
      "description":"Personalizare pizza",
      "figurina":"",
      "img_tort":"",
      "price":"29"
   }
];

window.onload = function() {
  var i, max = response2.length;
  for(i=0;i<max;i++) {
    console.log("product:["+ response2[i].product +"], price:["+ response2[i].price +"]");
  }
}
