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"]})

Answer 1

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": [ ]
            }
        ]
    }
