简化用户资料完整性检查逻辑

我正在基于Node.js和MySQL开发项目，需要实现用户资料完整性判断逻辑，需检查28个字段是否为空，目前编写了28个if-else语句来实现该功能，代码功能正常但过于冗长，希望能够简化代码。以下是我的实现代码：

let points = 0;
let point1 = 0;
let point2 = 0;
let point3 = 0;
let point4 = 0;
let point5 = 0;
let point6 = 0;
let point7 = 0;
let point8 = 0;
let point9 = 0;
let point10 = 0;
let point11 = 0;
let point12 = 0;
let point13 = 0;
let point14 = 0;
let point15 = 0;
let point16 = 0;
let point17 = 0;
let point18 = 0;
let point19 = 0;
let point20 = 0;
let point21 = 0;
let point22 = 0;
let point23 = 0;
let point24 = 0;
let point25 = 0;
let point26 = 0;

if (profileRes[0].username == null || profileRes[0].username == "") {
    point1 = points + 10;
} else if (profileRes[0].username != null || profileRes[0].username != "") {
    point1 = points += 0;
}
if (profileRes[0].phone == null || profileRes[0].phone == "") {
    point2 = points + 10;
} else if (profileRes[0].phone != null || profileRes[0].phone != "") {
    point2 = points += 0;
}
if (profileRes[0].email == null || profileRes[0].email == "") {
    point3 = points + 10;

    point3 = points += 0;
}

    point5 = points += 0;
}

    point7 = points += 0;

    point8 = points + 10;
} else if (profileRes[0].company_linkedin != null || profileRes[0].company_linkedin != "") {
    point8 = points += 0;

}

}
if (profileRes[0].category == null || profileRes[0].category == "") {
    point21 = points + 10;

    point21 = points += 0;

}
if (profileRes[0].branch == null || profileRes[0].branch == "") {
    point22 = points + 10;

}
let pint = point1 + point2 + point3 + point4 + point5 + point6 + point7 + point8 + point9 + point10 +point11 + point12 + point13 + point14 + point15 + point16 + point17 + point18 + point19 + point20 + point21 + point22 + point23 + point24 + point25 + point26;

let percentage = (pint * 100) / 260;

简化方案

核心思路是将需要检查的字段名存入数组，通过遍历数组统一处理每个字段的空值判断，避免重复代码：

// 定义需要检查的所有字段名，补充剩余2个字段即可
const profileFields = [
    'username', 'phone', 'email', 'company_name', 'profile_description',
    'short_description', 'company_url', 'company_linkedin', 'company_instagram',
    'company_facebook', 'number_of_employees', 'company_logo', 'founding_year',
    'is_profile_published', 'legal_name', 'billing_address', 'zip_code',
    'vat_number', 'sdi_codex', 'benefits', 'category', 'branch', 'coreActivities',
    'districts', 'legalFormCompany', 'commune'
];

const profile = profileRes[0];
let totalPoints = 0;

// 遍历字段数组，检查每个字段是否为空
profileFields.forEach(field => {
    const value = profile[field];
    // 判断值是否为null或空字符串
    if (value === null || value === '') {
        totalPoints += 10;
    }
});

// 计算完整性百分比，自动适配字段数量
const percentage = (totalPoints * 100) / (profileFields.length * 10);

简化优势

代码简洁：去掉大量重复的if-else和冗余变量，行数大幅减少
易维护：新增/删除检查字段只需修改profileFields数组，无需改动逻辑代码
逻辑严谨：修复原代码中else条件的逻辑错误（原代码!= null || != ""永远为true，属于无效判断）
扩展性强：若后续需调整单个字段分值，可将数组改为对象数组（如[{field: 'username', score:10}, ...]），灵活适配不同规则
