根据JavaScript中的条件将键值对附加到字典数组吗？
为此，请使用Object.assign()。以下是代码-
示例
const details =
{john:{'studentName':'John'},david:{'studentName':'David'},mike:{'studen
tName':'Mike'},bob:{'studentName':'Bob'},carol:{'studentName':'Carol'}},
join_values = ['David', 'Carol'],
output = Object.assign(
{},
...Object
.keys(details)
.map(key =>
({[key]: {
...details[key],
lastName: join_values.includes(details[key].studentName) ?
'Miller' : 'Smith'
}})))
console.log(output)要运行上述程序，您需要使用以下命令-
node fileName.js.
输出结果
在这里，我的文件名为demo157.js。这将产生以下输出-
PS C:\Users\Amit\JavaScript-code> node demo157.js
{
john: { studentName: 'John', lastName: 'Smith' },
david: { studentName: 'David', lastName: 'Miller' },
mike: { studentName: 'Mike', lastName: 'Smith' },
bob: { studentName: 'Bob', lastName: 'Smith' },
carol: { studentName: 'Carol', lastName: 'Miller' }
}
