我有這個陣列
let registers = [Register, Register, Register];
和
Register {name: 'Ray', email: '[email protected]', password: '1234'}
Register {name: 'Carl', email: '[email protected]', password: '4321'}
Register {name: 'Lina', email: '[email protected]', password: '5678'}
如何使用將@gmail.com 作為電子郵件的物件獲取新陣列？
uj5u.com熱心網友回復：
您可以在此處使用
const data = [
{ name: "Ray", email: "[email protected]", password: "1234" },
{ name: "Carl", email: "[email protected]", password: "4321" },
{ name: "Lina", email: "[email protected]", password: "5678" },
];
const output = data.filter((o) => o.email.match(/@gmail\.com$/));
console.log(output);uj5u.com熱心網友回復：
Array.filter與 一起使用String.includes。
Array.filter用一些條件過濾原始陣列，其中String.includes提供條件，電子郵件包含一個字串@gmail.com
const data = [{ name: 'Ray', email: '[email protected]', password: '1234' },
{ name: 'Carl', email: '[email protected]', password: '4321' },
{ name: 'Lina', email: '[email protected]', password: '5678' }];
const output = data.filter(node => node.email.includes('@gmail.com'));;
console.log(output);轉載請註明出處，本文鏈接：https://www.uj5u.com/qita/315791.html
