js手机号校验规则

function validatePhoneNumber(phoneNumber) {
    // 中国手机号正则表达式
    const regex = /^1[3-9]\d{9}$/;
    return regex.test(phoneNumber);
}

// 示例
const phoneNumber = "13800138000";
if (validatePhoneNumber(phoneNumber)) {
    console.log("手机号格式正确");
} else {
    console.log("手机号格式错误");
}

import { parsePhoneNumberFromString } from 'libphonenumber-js';

function validateInternationalPhoneNumber(phoneNumber, countryCode) {
    const phoneNumberObj = parsePhoneNumberFromString(phoneNumber, countryCode);
    return phoneNumberObj && phoneNumberObj.isValid();
}

// 示例
const phoneNumber = "+12125550123";
const countryCode = "US";
if (validateInternationalPhoneNumber(phoneNumber, countryCode)) {
    console.log("国际手机号格式正确");
} else {
    console.log("国际手机号格式错误");
}
