如何使用Javascript和Typescript

Question

[{
    "name": "employeeOne",
    "age": 22,
    "position": "UI",
    "city": "Chennai"
},
{
    "name": "employeeTwo",
    "age": 23,
    "position": "UI",
    "city": "Bangalore"
}
]

如果我删除“位置” json中的键和值，结果应该像[

[{
    "name": "employeeOne",
    "age": 22,
    "city": "Chennai"
}, {
    "name": "employeeTwo",
    "age": 23,
    "city": "Bangalore"
}]

如果我们在表中有员工列表，我只想删除所有员工职位列。如何使用JavaScript和Typescript实现此目标

我尝试过 const output = delete employee.position 但出现错误。

Answer 1

您那里有一系列对象。您将不得不遍历数组，分别删除每个对象中的属性。

Answer 2

看看删除操作

伪：

  JSONArray中的

foreach obj
  {
  删除obj [“ position”];
  }

也可以：

  

obj [position]
  obj.position

Answer 3

var data = [{
                "name": "employeeOne",
                "age": 22,
                "position": "UI",
                "city": "Chennai"
            },
            {
                "name": "employeeTwo",
                "age": 23,
                "position": "UI",
                "city": "Bangalore"
            }
          ];

data.forEach( item => {delete item.position;});

console.log(data);
