如何判断一个数组中的元素包含一个对象的所有属性值

问题描述

有下面这么一个对象模板，和基于这个对象模板产出的数组

// 对象模板
dataModel: {
    
    name      :"",
    type      :"",
    ability   :"",
    activity  :"",
    ip        :"",
    manName   :"",
    manPwd    :"",
    modelName :"",
    subCount  :"",
},
// 数组数据
doorConfig: [
    {
    "ability": "BCP", "activity": true, "id": 0, "ip": "192.168.66.64", "manName": "admin", "manPwd": "haikang123", "modelName": "DS-K1T804BEF", "name": "东门门禁", "type": "一体机", "subCount": 0, "isEdit": false}, 
    {
    "ability": "BCPF", "activity": true, "id": 1, "ip": "192.168.66.3", "manName": "admin", "manPwd": "haikang123", "modelName": "DS-K1T671MF", "name": "西门门禁", "type": "一体机", "subCount": 0, "isEdit": false}, 
    {
    "ability": "BCPF", "activity": true, "id": 2, "ip": "192.168.66.3", "manName": "admin", "manPwd": "haikang123", "modelName": "DS-K1T671MF", "name": "南门门禁", "type": "一体机", "subCount": 0, "isEdit": false}, 
    {
    "ability": "BCPF", "activity": true, "id": 3, "ip": "192.168.66.3", "manName": "admin", "manPwd": "haikang123", "modelName": "DS-K1T671MF", "name": "北门门禁", "type": "一体机", "subCount": 0, "isEdit": false}, 
    {
    "ability": "BCPF", "activity": true, "id": 4, "ip": "192.168.66.3", "manName": "admin", "manPwd": "haikang123", "modelName": "DS-K1T671MF", "name": "主门门禁", "type": "一体机", "subCount": 0, "isEdit": false}
]

现在的状态是：

• 数组中每个对象的属性，对比对象模板可能会有缺失
• 数组中的对象属性，可能为空

现在需要实现功能是，根据这个对象模板，判断数组中

• 是否存在为空的字段
• 是否缺失某个属性

实现这个判断功能：

allPropertiesExist(){
    
    // 1. 判断所有 doorConfig 元素是满足条件
    return this.doorConfig.every(item => {
    
        let allExist = true // 属性都存在的标识
        
        // 2. 对每个 doorConfig 的数组元素判断
        for (const label in this.dataModel){
    

            // 3. 是否存在对象中的每个属性，属性是否为空
            if (item.hasOwnProperty(label) && item[label] !== ''){
    

            } else {
    
                // 4. 任一一个属性不存在或为空时，就返回 false
                allExist = false
            }
        }
        return allExist
    })
},
