删除以前的 object 字段并在 javascript 中的对象数组中创建新字段

Question

I have a list of objects in javascript where I have a list with 1 field which is org_name like this:

const list=[
{ org_name:"Test1"},
{ org_name:"Test2"}
]

Now I want to change this list to:

const list=[
{ text:"Test1",value:"Test1"},
{ text:"Test2",value:"Test2"}
]

What I am doing is:

list.map(el => ({ ...el, text: el.org_name, value: el.org_name }));

Its not working,Any leads will be appreciated.

Answer 1

Just drop the ...el part since you don't need it.

 const list=[ { org_name:"Test1"}, { org_name:"Test2"} ]; const out = list.map(el => { return { text: el.org_name, value: el.org_name }; }); console.log(out);

Array.map creates new array. You want to update existing array, so loop through the array and update the object keys.

 const list = [ { org_name: "Test1" }, { org_name: "Test2" } ]; list.forEach(el => { el.text = el.org_name; el.value = el.org_name; delete el.org_name; }); console.log(list)
