法律研究過濾陣列中帶有空值的物件 JavaScript
假設我們有一個包含某公司員工資訊的陣列。但陣列包含一些錯誤資料，比如指向空字串或錯誤值。我們的任務是編寫一個函式，該函式接收陣列，清除名稱鍵為 null 或 undefined 或空字串的物件，並返回新的物件。
物件陣列如下所示 −
let data = [{
"name": "Ramesh Dhiman",
"age": 67,
"experience": 45,
"description": ""
}, {
"name": "",
"age": 31,
"experience": 9,
"description": ""
}, {
"name": "Kunal Dhiman",
"age": 27,
"experience": 7,
"description": ""
}, {
"name": "Raman Kumar",
"age": 34,
"experience": 10,
"description": ""
}, {
"name": "",
"age": 41,
"experience": 19,
"description": ""
}
]讓我們為該函式編寫程式碼 −
示例
let data = [{
"name": "Ramesh Dhiman",
"age": 67,
"experience": 45,
"description": ""
}, {
"name": "",
"age": 31,
"experience": 9,
"description": ""
}, {
"name": "Kunal Dhiman",
"age": 27,
"experience": 7,
"description": ""
}, {
"name": "Raman Kumar",
"age": 34,
"experience": 10,
"description": ""
}, {
"name": "",
"age": 41,
"experience": 19,
"description": ""
}
]
const filterUnwanted = (arr) => {
const required = arr.filter(el => {
return el.name;
});
return required;
};
console.log(filterUnwanted(data));輸出
控制檯中的輸出將為 −
[
{ name: 'Ramesh Dhiman', age: 67, experience: 45, description: '' },
{ name: 'Kunal Dhiman', age: 27, experience: 7, description: '' },
{ name: 'Raman Kumar', age: 34, experience: 10, description: '' }
]
