如何从 object 中删除属性但保留其值？

Question

I would like to know how can I remove the "formvalue1" property from the following object but keep its children.

{
  "formvalue1": {
    "title": "sdf",
    "tname": "sdff",
    "taddress": "dfsdf"
  }
}

Answer 1

Try reassigning the object:

let obj = {"formvalue1": { "title":"sdf", "tname":"sdff", "taddress":"dfsdf" } };
obj = obj.formvalue1;
console.log(obj)

If the original JSON is a string and not a JSON object. In javascript you can use JSON.parse to parse the string into an object literal (see comment below pointing out the discrepancy).

const jsonStr = '{"formvalue1": {"title": "sdf", "tname": "sdff", "taddress": "dfsdf"}}'
let obj = JSON.parse(jsonStr);
obj = obj.formvalue1;
console.log(obj)

Answer 2

you use some destructuring

 const d = { "formvalue1": { "title": "sdssssssf", "tname": "sdff", "taddress": "dfsdf" } } const { formvalue1 } = d const nd = formvalue1 console.log(nd)
