递归处理list-选择特定属性和去除多余属性

element-ui级联选择组件list 注意要点涉及方法

export const loop_ = (data) => {
  let office = data.map(item => {
    // value必须字符串;children为空时,必须去掉其属性
    item = {
      label: item.label,
      value: item.value + '',
      children: loop_(item.children)
    }
    if (item.children.length === 0) {
      let {
        children,
        ...new_item
      } = item;
      return new_item
    }
    return item
  })
  return office
}
