如何用其他字符串javascript替换所有子字符串

Question

我正在加载数据，然后将其放入输入中，它输入的数据位于名称“业务类型”下，我需要将其更改为“业务类型 ID”

例如

其实我有

[{"URL":"http://www.restaurant.com","Business Type":1},{"URL":"http://www.hotel.com","Business Type":2}]

我想：

1. 将所有"Business Type" 替换为"businessTypeId"

2. [delete square brackets]

3. 将""添加到id（id是业务类型中的数字）

这是预期的结果

{"url":"http://www.restaurant.com","businessTypeId":"1"},{"url":"http://www.hotel.com","businessTypeId":"2"}

这是我的代码

placesArray.push(JSON.stringify(results.data));
console.log(placesArray);
document.getElementById('places').value = placesArray;

placesArray 包含我要更改的字符串

Answer 1

你可以使用数组map函数：

const data = [
  { "URL":"http://www.restaurant.com", "Business Type": 1},
  { "URL":"http://www.hotel.com", "Business Type": 2 },
];

const result = data.map(value => ({
  url: value.URL,
  businessTypeId: value["Business Type"]?.toString(),
}));

console.log(result);

Answer 2

const data=
[{"URL":"http://www.restaurant.com","Business Type":1},{"URL":"http://www.hotel.com","Business Type":2}]

//"Buisness Type" is a key, so firstly, go through each index, then in each index search through its keys and do replacing stuffs
data.forEach(a=>{
  Object.keys(a).forEach(b=>{
    if(b=="Business Type"){//what you want replaced
      var n=a[b].toString() //value to put in replaced key(and to string because you told me that you want string data not number data)
      delete(a[b]) //deleting old key
      a["businessTypeId"]=n //adding replaced key with previous value
    }
  })
})

console.log(data)
