我有这个

[{"n1":{"0":"2"},"f1":{"0":3}},{"n1":{"1":"3"},"f1":{"1":2}}]

我想要这个

[{"n1":{"0":"2", "1":"3"},"f1":{"0":3, "1":2}}]

使用下划线或Jquery..请指导...

你可以使用终极的 reduce 用纯 JS 来完成这个任务。 (我亲切地称之为单一职能军队)和一堆for-in。像这样的事情:

let arr = [{"n1":{"0":"2"},"f1":{"0":3}},{"n1":{"1":"3"},"f1":{"1":2}}]

let modified = arr.reduce((res, objs) => {
  for (let key in objs) {
    res[key] = res[key] || {}
    for (let i in objs[key]) {
      res[key][i] = objs[key][i]
    }
  }
  return res
}, {})

let result = [modified]

console.log(result)

.as-console-wrapper { max-height: 100% !important; top: 0; }
