使用Javascript的JSON数据中的层次深度逻辑

Question

只想知道您在此问题中使用javascript的代码逻辑。 我想在层次数据中进行深度级别跟踪。 数据可以具有更多层。

这是我的样本数据

原始数据

我想在每个属性中放置一个depth属性

编辑数据

样本数据

[{
"id": 1,
"label": "System",
"parent_id": null,
"description": "System Manager",
"children": [{
    "id": 2,
    "label": "base",
    "parent_id": 1,
    "description": "Base Manager",
    "children": [{
        "id": 3,
        "label": "Menus",
        "parent_id": 2,
        "description": "menu manager",

    },
    {
        "id": 4,
        "label": "Roles",
        "parent_id": 2,
        "description": "Role Manager",

    },
    {
        "id": 5,
        "label": "Users",
        "parent_id": 2,
        "description": "User Manager",

    }]
}]
},
{
    "id": 6,
    "label": "Customs",
    "parent_id": null,
    "description": "Custom Manager",
    "children": [{
        "id": 7,
        "label": "CustomList",
        "parent_id": 6,
        "description": "CustomList",

    }]
}

Answer 1

但是，你去了。 我将您的数据简化为一个简单的示例。 如您所见，Iam使用的是递归函数，每次调用都会将其递增到下一个级别。

 var example = [{ "id": 1, "label": "System", "parent_id": null, "description": "System Manager", "children": [{ "id": 2, "label": "base", "parent_id": 1, "description": "Base Manager", "children": [{ "id": 3, "label": "Menus", "parent_id": 2, "description": "menu manager" }, { "id": 4, "label": "Roles", "parent_id": 2, "description": "Role Manager", }, { "id": 5, "label": "Users", "parent_id": 2, "description": "User Manager" }] }] }, { "id": 6, "label": "Customs", "parent_id": null, "description": "Custom Manager", "children": [{ "id": 7, "label": "CustomList", "parent_id": 6, "description": "CustomList" }] }]; var res = document.getElementById("res"); var addDepth = function(json, depth){ return json.map(e => { e.depth = depth; if(e.children){ e.children = addDepth(e.children, depth + 1); } return e; }); } res.innerHTML = JSON.stringify(addDepth(example, 0), undefined, 2); 

 <pre id="res"></pre>
