可以在多个数组中命名不同的数组吗？

Question

我想知道是否可以在mutli数组中命名数组，例如，我知道您可以这样做：

var cars = new Array();
cars[0] = "Saab";
cars[1] = "Volvo";
cars[2] = "BMW";

我想知道某些人是否可以这样做：

var cars = new Array();
cars[Saab] = "9-3 Aero";
cars[Volo] = "S80";
cars[BMW] = "I8";

如果没有，那就好了--只是想知道是否有人有办法做到这一点。

Answer 1

正确的语法是

var cars = {};
cars.Saab = "9-3 Aero";
cars.Volvo = "S80";
cars.BMW = "I8";

或

var cars = {
   Saab:  "9-3 Aero",
   Volvo: "S80",
   BMW:   "I8"
}

这被称为对象文字。

Answer 2

javascript对象被命名为数组！

var cars = {};
cars["Saab"] = "9-3 Aero";
cars["Volo"] = "S80";
cars["BMW"] = "I8";

Answer 3

你也可以：

var cars = new Array();
cars[0]['brand'] = "Saab";
cars[1]['brand'] = "Volvo";
cars[2]['brand'] = "BMW";

cars[0]['type'] = "9-3 Aero";
cars[1]['type'] = "S80";
cars[2]['type'] = "I8";
