Question

我有json嵌套数组，如下所示：

 Parent: {
      Child1: [
        {name:'grandchild1', value:'abc', checked:true},
        {name:'grandchild2', value:'pqr', checked:false}
      ],
      Child2: [
        {name:'grandchild3', value:'abcd', checked:false},
        {name:'grandchild4', value:'pqrs', checked:true}
      ],
parent2{...........}....
    };

我需要将其转换为：

 [  
   {  
      "filename":"Parent",
      "children":[  
         {  
            "filename":"Child1",
            "children":[  
               {  
                  "filename":"grandchild1",
                  "type":"ts"
               },
               {  
                  "filename":"grandchild2",
                  "type":"ts"
               }
            ]
         },
         {  
            "filename":"Child2",
            "children":[  
               {  
                  "filename":"grandchild3",
                  "type":"ts"
               },
               {  
                  "filename":"grandchild4",
                  "type":"ts"
               }
            ]
         }
      ]
   },
   { filename:"Parent1"..........
   },....
]

它是角形材料树的一部分。他们有示例代码Link

尝试以下代码：

Object.keys(obj).reduce<FileNode[]>((accumulator, key) => {
      const value = obj[key];
      const node = new FileNode();
      node.filename = key;

      if (value != null) {
        if (typeof value === 'object') {
          node.children = this.buildFileTree(value, level + 1);
        } else {
          node.type = value;
        }
      }

      return accumulator.concat(node);
    }, []);
  }

但是没有得到我所需要的。

请建议我如何转换为以下格式，以便它接受相应的方式？

您可以使用for of和for in函数

const list = {Parent1 :{
    Child1: [
      {name:'grandchild1', value:'abc', checked:true},
      {name:'grandchild2', value:'pqr', checked:false}
     ] ,
  Child2: [
   {name:'grandchild3', value:'abcd', checked:false},
   {name:'grandchild4', value:'pqrs', checked:true}
  ]
}, Parent2 :{
    Child1: [
      {name:'grandchild1', value:'abc', checked:true},
      {name:'grandchild2', value:'pqr', checked:false}
     ] ,
  Child2: [
   {name:'grandchild3', value:'abcd', checked:false},
   {name:'grandchild4', value:'pqrs', checked:true}
  ]
}};

const res = []

for(let parent in list){

let parentTemp = {
    filename : parent,
    children : []
}

  for(let child in list[parent]){

      let childTemp = {filename : child, children : []};

      for(let grandChild of list[parent][child]){
          childTemp.children.push({filename : grandChild.name, type : grandChild.value, status: grandChild.checked});
      }
      parentTemp.children.push(childTemp);


  }
  res.push(parentTemp);
}


console.log(res);
