javascript - 如何在数组中添加对象的键？

Question

伙计们。我有这样的数组

array = [{name:"A",data:"..."},{name:"B",data:"..."},{name:"C",data:"..."}]

我想将此数组编辑为

array = [ "A":{name:"A",data:"..."},"B":{name:"B",data:"..."},"C":{name:"C",data:"..."}

如何根据对象自身的值设置对象键？

Answer 1

要获取对象，您可以使用 Object.fromEntries与映射的键/值对

var array = [{ name: "A", data: "..." }, { name: "B", data: "..." }, { name: "C", data: "..." }],
    result = Object.fromEntries(array.map(o => [o.name, o ]));

console.log(result);

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