使用 javascript 循环遍历嵌套对象

Question

我得到了这段代码，想用 foreach() 函数显示所有图像。

var btx = [];
btx["main"] = {};
btx["main"]["us-001"] = {src: "hxxps://domain.com/kus-001.jpg", width: "128" , height: "256"};
btx["main"]["us-002"] = {src: "hxxps://domain.com/kus-002.jpg", width: "128" , height: "256"};

谢谢

Answer 1

for (var key in btx["main"]) {
    console.log (btx["main"][key]["src"])
}
