如何将此Javascript变量转换为有效的JSON？

Question

我正在解析一些当前写成JavaScript变量的数据，但我想将其转换为有效的JSON，以便我可以解析它。这是变量的样子：

var machines = [{
    category: "Category 1",
        items: [{
            name: "Test 1",
            description: "Lorem Ipsum"
        }, {
            name: "Test 2",
            description: "Lorem Ipsum"
        }]
    }, {
    category: "Category 2",
        items: [{
            name: "Test 3",
            description: "Lorem Ipsum"
        }, {
            name: "Test 4",
            description: "Lorem Ipsum"
        }]
    }
];

我知道我必须删除var machines =部分，但除此之外我还不确定如何制作这个有效的JSON。

Answer 1

您必须使用原生的 JSON.stringify() 方法。

这是一个有用的 DEMO ：

var machines = [{
  category: "Category 1",
  items: [{
    name: "Test 1",
    description: "Lorem Ipsum"
  }, {
    name: "Test 2",
    description: "Lorem Ipsum"
  }]
}, {
  category: "Category 2",
  items: [{
    name: "Test 3",
    description: "Lorem Ipsum"
  }, {
    name: "Test 4",
    description: "Lorem Ipsum"
  }]
}];

var json = JSON.stringify(machines);
console.log(json);

Answer 2

通过JSON.stringify()。

var machines = [{
  category: "Category 1",
  items: [{
    name: "Test 1",
    description: "Lorem Ipsum"
  }, {
    name: "Test 2",
    description: "Lorem Ipsum"
  }]
}, {
  category: "Category 2",
  items: [{
    name: "Test 3",
    description: "Lorem Ipsum"
  }, {
    name: "Test 4",
    description: "Lorem Ipsum"
  }]
}];


var json = JSON.stringify(machines);
console.log(json);
