Javascript 在json/array/object上循环

我已经在这上面呆了一段时间了。如何在具有数组值的对象上循环。请对我的帮助表示感谢。JSON数据结构不是我的强项套件

var storeProducts = {"items": [
 {
   "imgsrc": "https://cdn.shopify.com/s/files/1/0094/2252/products/M997ST_6940.progressive.jpg?v=1497039024",
   "productname": "New Balance",
   "productlistprice": "$240",
   "discounted": "false",
   "productprice": "",
 },
 {
   "imgsrc": "https://cdn.shopify.com/s/files/1/0094/2252/products/Peacoat_363758_02_6428.progressive.jpg?v=1496428432",
   "productname": "Puma Sneakers",
   "productlistprice": "$120",
   "discounted": "false",
   "productprice": "",
 },
 {
   "imgsrc": "https://cdn.shopify.com/s/files/1/0094/2252/products/Titan_Weave_WhiteBlueEstate_50117182901_C6501_5945-78.progressive.jpg?v=1494616290",
   "productname": "Diadora",
   "productlistprice": "$100",
   "discounted": "true",
   "productprice": "190",
 },
]};

@亚瑟是对的

解决方案：

foreach( var i = 0; i < storeProducts.items.length; i++ ) {
    var item = storeProducts.items[i];
}

假设您想要获取所有imgsrc URL。你可以这样做

let imgURL = storeProducts.items.map(product =>product.imgsrc);

要获取数组中的第一项，只需执行以下操作

设firstImgURL=imgURL[0]

让storeProducts={ 项目：[ { imgsrc：https://cdn.shopify.com/s/files/1/0094/2252/products/M997ST_6940.progressive.jpg?v=1497039024, productname:New Balance， 产品价格：$240， 打折：错， 产品价格：， }, { imgsrc：https://cdn.shopify.com/s/files/1/0094/2252/products/Peacoat_363758_02_6428.progressive.jpg?v=1496428432, 产品名称：彪马运动鞋， 产品价格：$120， 打折：错， 产品价格：， }, { imgsrc：https://cdn.shopify.com/s/files/1/0094/2252/products/Titan_Weave_WhiteBlueEstate_50117182901_C6501_5945-78.progressive.jpg?v=1494616290, 产品名称：Diadora， 产品价格：$100， 对,， 产品价格：190， }, ]}; var imgURL=storeProducts.items.mapproduct=>product.imgsrc；

console.logimgURL；这似乎是一个非常常见的问题。。。你确定你在寻找答案吗？请参阅示例或…或更简单的：storeProducts.items.forEach item=>console.log item
