递归判断多维数组中对象是否有值

Posted 2021-12-20 yuzhongyu

一个项目需求中，需要判断数组中的对象是否有值，先看下数据结构：

let list = [
        
            value: "1",
            children: [
                
                    value: "2",
                ,
                
                    value: "3",
                    children: [
                        
                            value: "4",
                        ,
                    ]
                
            ]
        ,
        
            value: "5",
        
    ]

那么如何进行判断多层子集是否有值呢？这里就会用到递归来实现

    function ruleValidate(data) 
        let flag = true;
        var arr = [];
        function judgeChildren(data) 
            data.forEach(e => 
                if (!flag) 
                    return
                
                if (!e.value) 
                    flag = false;
                    return;
                 else if (e.children && e.children.length) 
                    judgeChildren(e.children);
                
            );
        
        judgeChildren(data);
        return flag;
    
    console.log(ruleValidate(list))
