[英]Deleting element and changing element property in an Array of objects
因此,有一个名为 employees 的 object 数组具有员工的凭据。 如果员工的名字是 Theo,我应该删除 object,如果员工的名字是 Lorie,我应该将部门的属性更改为“HR”特性。 但它不会返回迭代数组。 也许我需要使用 .reduce() 方法这是我尝试过的代码
它应该工作!
你的对象数组。
var employees = [
{
"firstName": 'Von',
"lastName": 'budibent',
"email": "email@mail.com",
"departement": "Sales"
},
{
"firstName": 'Theo',
"lastName": 'Trill',
"email": "email@mail.com",
"departement": "Services"
},
{
"firstName": 'Lorie',
"lastName": 'Trill',
"email": "email@mail.com",
"departement": "Research and Development"
}
];
然后您需要按firstName
过滤,然后映射数据。
var adjustedEmployees = employees
.filter(employee => employee.firstName !== 'Theo')
.map((employee) => {
if (employee.firstName === 'Lorie') employee.departement = 'HR';
return employee;
});
//我需要使用没有参数的function,我想出了怎么做。
//Remove employe with firstname 'Theo'
var result = employees.filter(employee => employee.firstName !== 'Theo');
//Change department of Lorie to 'HR'
result.forEach(el => {
el.departement = el.firstName === 'Lorie' ? 'HR' : el.departement
})
