Laravel生成jstree的json数据

Question

laravel从数据库中取出来的数据如何封装成jstree能够读取的模型？如果有能给个实例就好了……

$("#tree_4").jstree({

    core: {

        themes: {

            responsive: !1

        },

        check_callback: !0,

        data: {

            url: function (e) {

                return "{{ route('api.deparment') }}"

            },

            data: function (e) {

                return {

                    parent: e.id

                }

            }

        }

    },

    types: {

        "default": {

            icon: "fa fa-folder icon-state-warning icon-lg"

        },

        file: {

            icon: "fa fa-file icon-state-warning icon-lg"

        }

    },

    state: {

        key: "demo3"

    },

    plugins: ["dnd", "state", "types"]

})

把你数据库取出的数据遍历一下，json结构官方的github已经给出了[{  "id":1,"text":"Root node","children":[     {"id":2,"text":"Child node 1"},     {"id":3,"text":"Child node 2"}   ] }]这是我做的例子[     {        "id": 1,          "text": "root",          "value": "root",          "pid": 0,          "type": 0,          "children": [             {                "id": 2,                  "text": "Status",                  "value": "status",                  "pid": 1,                  "type": 1,                  "children": [                     {                        "id": 5,                          "text": "open",                          "value": "open",                          "pid": 2,                          "type": 1                     },                      {                        "id": 6,                          "text": "cancelled",                          "value": "cancelled",                          "pid": 2,                          "type": 1                     }                 ]             },              {                "id": 3,                  "text": "Payment Status",                  "value": "financial_status",                  "pid": 1,                  "type": 1,                  "children": [ ]             },              {                "id": 4,                  "text": "Tagged With",                  "value": "tag",                  "pid": 1,                  "type": 1,                  "children": [ ]             },              {                "id": 7,                  "text": "Date",                  "value": "process_at",                  "pid": 1,                  "type": 1,                  "children": [                     {                        "id": 8,                          "text": "in the last week",                          "value": "past_week",                          "pid": 7,                          "type": 1                     },                      {                        "id": 9,                          "text": "on or before",                          "value": "processed_at_max",                          "pid": 7,                          "type": 2                     }                 ]             },              {                "id": 10,                  "text": "Custom",                  "value": "custom",                  "pid": 1,                  "type": 2,                  "children": [ ]             }         ]     } ]
