Question

我是否可以缩短此代码？看起来很多余。谢谢！

let sanitizedFirstName = sanitize(firstName).trim()
let sanitizedLastName = sanitize(lastName).trim()
let sanitizedEducationalBackground = sanitize(educationalBackground).trim()
let sanitizedAddress = sanitize(address).trim()
let sanitizedRole = sanitize(role).trim()
let sanitizedEmail = sanitize(email).trim()
let sanitizedPassword = sanitize(password).trim()
let sanitizedFarmAddress = sanitize(farmAddress).trim()

Answer 1

您可以使用分解。

const [sanitizedFirstName, sanitizedLastName, sanitizedEducationalBackground] = [firstName, lastName, educationalBackground].map(x => sanitize(x).trim())

但是，我仍然建议使用更清晰的变量来读取维护。

示例：

const sanitize = (str = "") => str.replace(/\W+/g, "-");
console.log(sanitize("Test me"));

const [firstName, lastName, fullName] = ["Deepak V", "Vish@@", "Deepak V Visha@@"].map(sanitize)
console.log([firstName, lastName, fullName])

或者您可以创建一个util函数，可以清理整个对象。请参阅下面的示例。

const sanitizeObject = (obj) =>
  Object.entries(obj).reduce((m, [key, value]) => {
    m[key] = sanitize(value);
    return m;
  }, {});

const sanitize = (str = "") => str.replace(/\W+/g, "-");
const sanitizeObject = (obj) =>
  Object.entries(obj).reduce((m, [key, value]) => {
    m[key] = sanitize(value);
    return m;
  }, {});
const person = {
  firstName: "Deepak, R",
  lastNam: "V Vis",
  address: "356 $hhshshs",
  age: 30,
  salary: 200,
};
const sanitizedPartial = sanitizeObject({
  firstName: person.firstName,
  lastNam: person.lastNam,
  address: person.address,
});
const updatedPerson = {
  ...person,
  ...sanitizedPartial,
};
console.log(updatedPerson);

一种选择是将vars放入数组并循环它们：


[firstName, lastName, ..., farmAddress].forEach(funciton (name) {
   window['sanitized' + (name.charAt(0).toUpperCase() + name.slice(1))] = sanitize(name).trim()
});

有什么办法可以缩短我在JavaScript中的代码？
