如何在Javascript中访问对象

I have this object from a JSON file

我从JSON文件中获取此对象

{
    "Apple": "Red",
    "Orange": "Orange",
    "Guava": "Green",   
}

Then I converted it into Object using

然后我用它将它转换为Object

var data = JSON.parse(dataFromJson);

then it will output JavaScript object

然后它将输出JavaScript对象

Question

题

Is it possible to access "Apple", "Orange", "Guava" then store it into var fruits then "Red", "Orange","Green" into var Color

是否可以访问“Apple”，“Orange”，“Guava”然后将其存储到var fruits中，然后将“Red”，“Orange”，“Green”存入var颜色

2 个解决方案

#1

You can also do something like this:

你也可以这样做：

var data = JSON.parse(dataFromJson);

var fruits = [];
var colors = [];

for(var fruit in data) {
    fruits.push(fruit);
    colors.push(data[fruit]);
}

Yes, there is several ways to do this, either iterate over the object and do it "manually"

是的，有几种方法可以做到这一点，迭代对象并“手动”执行

for (var i = 0;i > data.length; i++) {
    colors.push(data[i]);
    fruits.push(Object.keys(data)[i]);
}

or let the Object methods do this for you.

或让Object方法为您执行此操作。

var fruits = Object.keys(data);
var colors = Object.values(data);

Have some reading about the Object here

在这里阅读一些关于Object的内容

The Object.values() method is EXPERIMENTAL as stated here

Object.values（）方法是如此处所述的实验
