父母和孩子创建的json数据问题

Question

for(var d in response.data) {
    var item = response.data[d];
    console.log("test-1234=="+JSON.stringify(item));
}

If you take the data, it comes out as below.

test-1234=={"id":3,"isLeaf":"false","name":"bang","pid":0,"didabled":null}
test-1234=={"id":4,"isLeaf":"true","name":"test1","pid":3,"didabled":null}
test-1234=={"id":5,"isLeaf":"true","name":"test2","pid":3,"didabled":null}
test-1234=={"id":6,"isLeaf":"false","name":"test3","pid":0,"didabled":null}

I want to create a relationship between parents and children based on pid.
Like below. Please give me a solution.

[
{
    name: 'bang',
    id: 3,
    pid: 0,
    dragDisabled: true,
    children: [
        {
            name: 'test1',
            id: 4,
            isLeaf: true,
            pid: 3
        },
       {
            name: 'test2',
            id: 5,
            isLeaf: true,
            pid: 3
        }
    ]
},
 {
            name: 'test3',
            id: 6,
            isLeaf: true,
            pid: 0
        }
]

Try like this.

 var arr = [ { "id": 3, "isLeaf": "false", "name": "bang", "pid": 0, "didabled": null }, { "id": 4, "isLeaf": "true", "name": "test1", "pid": 3, "didabled": null }, { "id": 5, "isLeaf": "true", "name": "test2", "pid": 3, "didabled": null }, { "id": 6, "isLeaf": "false", "name": "test3", "pid": 0, "didabled": null }, { "id": 7, "isLeaf": "true", "name": "test\\43", "pid": 4, "didabled": null } ] var res = []; for(var d in arr) { var item = arr[d]; if(item.pid != 0){ findParentAndPush(item) } else { item.children = []; res.push(item); } } function findParentAndPush(item){ var filtered = arr.filter(data => data.id === item.pid); item.children = []; filtered[0].children.push(item) } console.log(res)
