Javascript:对象数组的数据验证

Question

我正在运行这个任务来教我的兄弟，他被要求创建一个 Javascript 简单程序来验证这些数据

[
    {code: ‘10001’, amount: ‘’},
    {code: ‘10002’, amount: ’50.00’},
    {code: ‘’, amount: ’60.00’},
    
]

我需要显示错误，如果有金额，代码不应为空。

Answer 1

归功于@Majed Badawi，但具有固定的验证表达式。

const data = [
  {code: '1000', amount: ''},       // is okay
  {code: '10002', amount: '50.00'}, // absolutely valid
  {code: '', amount: '60.00'},      // invalid
  {code: '', amount: ''},           // empty but still valid
];

const validFlags = data.map(e => !e.amount || e.code);
const isValid = validFlags.every(f => f);

console.log("Validation per record", validFlags.map(Boolean));
console.log("Final result", isValid);
