怎么通过js递归实现跟element-UI这种数据格式？

可以参考下这个简单版本, 原理差不多, 都是递归

Answer 2

能给出这样源数据结构的真是位神人，楼主请跳起来替我踹Y一脚，以示敬仰！

Answer 3

这样？

const data = {...};

function format(nodes) {
    return Object.values(nodes).map(({data: d, child: c}) => 
        ({value: d.id, label: d.title, ...(c && Object.keys(c).length ? {children: format(c)} : {})})
    )
}

const result = format(data);

结果：

[
  {
    "value": 364,
    "label": "工程技术",
    "children": [
      {
        "value": 378,
        "label": "关键设备/部件",
        "children": [
          {
            "value": 383,
            "label": "反应釜"
          }
        ]
      }
    ]
  },
  {
    "value": 365,
    "label": "维护保养",
    "children": [
      {
        "value": 376,
        "label": "动设备"
      },
      {
        "value": 377,
        "label": "静设备"
      }
    ]
  }
]
