如何在javascript中将对象数组转换为对象的索引对象？

Question

我有以下数组以及它的结构如何返回给我的图片：

const connections = [1:{fromBox: 0, fromConnector: "port_0", toBox: 1, toConnector: "port_0"},
                     1:{fromBox: 0, fromConnector: "port_1", toBox: 1, toConnector: "port_1"}
                    ]

并且我需要创建一个具有此结构的对象以与我的代码兼容：

"connections": {
    "0": {
      "fromBox": "0",
      "fromConnector": "port_0",
      "toBox": "1",
      "toConnector": "port_0",
    },
    "1": {
      "fromBox": "0",
      "fromConnector": "port_1",
      "toBox": "1",
      "toConnector": "port_1"
    }
  }

看到类似的疑问，我已经明白，使用归约方法我应该能够实现它，但是当尝试将它们在数组中的索引放入对象时，它给了我就好像数组的元素一样未定义

      const connectionsKeys = Object.keys(connections);

      const result = connections.reduce((c, v) => {
        c[v.connectionsKeys] = c[v.connectionsKeys] || {}; 

        return c;
      }, {});

任何帮助或指导将不胜感激。 提前谢谢你

Answer 1

const connections = [{fromBox: 0, fromConnector: "port_0", toBox: 1, toConnector: "port_0"},
                     {fromBox: 0, fromConnector: "port_1", toBox: 1, toConnector: "port_1"}
                    ]


function convertToObject(arr){
  return Object.assign({},arr)
}

console.log(convertToObject(connections));

Answer 2

您帖子中的第一张图片（来自控制台的那张）在结构上与分配给恒定连接的图片不同。 图片翻译成js代码应该是这样的

const connections = [{1:{fromBox: 0, fromConnector: "port_0", toBox: 1, toConnector: "port_0"}},
                 {1:{fromBox: 0, fromConnector: "port_1", toBox: 1, toConnector: "port_1"}}
                ]

从这个结构中，您可以进行以下归约，最终得到您需要的结构：

const result = connections.reduce((acc, curr, index) => {
    acc[index] = curr['1'];

    return acc;
  }, {});
