这样我就可以使用该冰柱图了。有没有一种方法可以手动完成此任务?

由于数据非常简单-namesizechildrensize / children是互斥的,因此您可以一个简单的函数,它基于namesize创建一个对象,然后使用Object.assign在子对象上递归调用该对象以提供帮助。

function convertObject(obj){
    let ch
    if (obj.children) {
       ch = obj.children.reduce((a, c) => Object.assign(a, convertObject(c)), {})
    }
    return {[obj.name]: (obj.size || ch)}
}
console.log(convertObject(obj))

其工作方式:convertObject获取一个对象并返回一个具有name属性的对象。如果传入的obj具有size,则返回的对象将仅为{obj.name: obj.size}。如果传入的对象具有children属性,它将对每个孩子调用convertObject。这些调用中的每一个都会返回一个对象,reduce会将它们全部合并为一个对象,我们在上面将其称为ch。在有子级的情况下,converObject函数以{object.name, ch}的形式返回一个对象。

可以理解,这有点困难-递归函数需要一点时间来适应。
