javascript - 格式化扩展的 JSON 数据

Question

我有一个类似这样的 JSON 对象。与 JSON.stringify(Object) 一起使用时，它看起来像这样。

 "[
    ["Individual Id","Individual Last Name","Individual First Name","Individual Middle Name"],
    ["1268933","mrs","jeanine","marie"]
    ["1268934","mr","jasmine","curry"]
 ]"

将数据重新格式化为以下格式的最快方法是什么。

[
{
    "Individual Id": "1268933",
    "Individual Last Name": "mrs",
    "Individual First Name": "jeanine",
    "Individual Middle Name": "marie"
},
{
    "Individual Id": "1268934",
    "Individual Last Name": "miss",
    "Individual First Name": "jasmine",
    "Individual Middle Name": "curry"
}
]

Answer 1

您可以array#shift第一个数组，然后使用array#map和array#reduce生成数组。

var arr = [["Individual Id","Individual Last Name","Individual First Name","Individual Middle Name"],["1268933","mrs","jeanine","marie"],["1268934","mr","jasmine","curry"]],
  headers = arr.shift(),
  result = arr.map(a => a.reduce((r,v,i) => (r[headers[i]] = v, r), {}));
console.log(result);

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