JS树形数组转换为键值对的对象

    // 核心代码
    // 第一个参数：接受数组，元素里面的children字段为子元素
    // 第二个参数：元素里面没有children或children长度为0时，选取作为默认值的字段
    function treeToObj(treeArr, defValField = undefined) {
        let obj = {};
        for (let i = 0; i < treeArr.length; i++) {
            let node = treeArr[i];
            if (node.children && node.children.length) {
                obj[node.name] = treeToObj(node.children)
            } else {
                obj[node.name] = node.hasOwnProperty(defValField) ? node[defValField] : {}
            }
        }
        return obj;
    }
    // 运行
    let treeList = [
        {
            name: 'A',
            value: 'deded',
            children: [{
                name: 'B',
                value: 'bbbb',
                children: [{
                    name: 'C',
                    value: 'cccc'
                }]
            }]
        },
        {
            name: 'J',
            value: 'deded'
        },
        {
            name: 'K',
            value: 123
        },
        {
            name: 'Z',
            value: {},
            children: [{
                name: 'Y',
                value: {}
            }]
        },
    ]
    console.log('treeToObj(treeList)', treeToObj(treeList))
