使用ES6的filter函数查找树形节点数据

场景

有一个树形节点数据，想要根据关键词查找子节点，得到一个过滤后的新树形数据。

树形数据

let treeData = [
    {
        id: '1',
        name: '张三',
        children: [
            {
                id: '1.1',
                name: '李四',
                children: [
                    {
                        id: '1.1.1',
                        name: '黄五',
                        children: []
                    },
                    {
                        id: '1.1.2',
                        name: '老六',
                        children: []
                    },
                ]
            },
            {
                id: '1.2',
                name: '孙七',
                children: []
            },
        ]
    },
    {
        id: '2',
        name: '王八',
        children: [
            {
                id: '2.1',
                name: '赵九',
                children: [
                    {
                        id: '',
                        name: '刘十',
                        children: []
                    },
                    {
                        id: '2.1.2',
                        name: 'III',
                        children: []
                    },
                ]
            },
            {
                id: '2.2',
                name: '渔船',
                children: []
            },
            {
                id: '2.3',
                name: '渔船轨迹',
                children: []
            },
            {
                id: '2.4',
                name: 'LLL',
                children: []
            },
        ]
    }
]

递归函数

function deepFilter(array, value) {
    return array.filter(function (item) {
        let result = false;
        if (item.children && item.children.length > 0) {
            item.children = deepFilter(item.children, value);
            result = item.children && item.children.length > 0;
        } else {
            result = item.name.includes(value);
        }
        return result;
    });
}

调用

let newArr = deepFilter(treeData, '渔船');
// 格式化打印看看效果 
console.log(JSON.stringify(newArr, null, 4));
