 fineUi的Tree我们一般这么配

var items = this._formatTreeItems(BI.Tree.transformToTreeFormat(this.store.getTreeJsonWithNode()), 0);

 t = {
                            type: "bi.custom_tree",
                            $testId: "decision-normal-table-tree-scroll",
                            $value: e.authType + "-" + e.entityType,
                            ref: function (e) {
                                n.tree = e
                            },
                            expander: {
                                type: "dec.base.tree_expander",
                                isDefaultInit: !1,
                                el: {},
                                popup: {
                                    type: "bi.custom_tree"
                                }
                            },
                            items: t,
                            itemsCreator: function (t, i) {
                                e.itemsCreator(t, function (e) {
                                    e = n.store.cacheTreeData(e, t);
                                    var a = n._formatTreeItems(e, t.node ? t.node.layer : 0)
                                    console.log("a:" + a)
                                    i(a)
                                })
                            },
                            el: {
                                type: e.lazy ? "dec.component.lazy_loader" : "dec.component.gradually_loader",
                                next: !1,
                                getScrollParent: function () {
                                    return n.tree.element
                                },
                                el: {
                                    type: "bi.button_tree",
                                    chooseType: 1,
                                    layouts: [{
                                        type: "bi.vertical"
                                    }]
                                }
                            },
                            listeners: [{
                                eventName: BI.Controller.EVENT_CHANGE,
                                action: function (e, t, i) {
                                    n.fireEvent(BI.Controller.EVENT_CHANGE, arguments)
                                }
                            }]
                        };


 itemsCreator是异步数据回调接口，
    itemsCreator: function (t, i) {
                                    e.itemsCreator(t, function (e) {
                                        e = n.store.cacheTreeData(e, t);
                                        var a = n._formatTreeItems(e, t.node ? t.node.layer : 0)
                                        console.log("a:" + a)
                                        i(a)
                                    })
                                },
    这里是调用options中的itemsCreator来获取数据，回调函数获取到数据后，调用i(a)来渲染数据。
    a的数据格式一般为：[
        {


            children: Array(5)
            id: "-1_0"
            isParent: true
            layer: 0 //控制层级
            open: true //是否打开
            order: 0
            pId: null //父id
            selected: true //是否选中
            text: "中国铁建"
        }
    ]
    options的itemsCreator中一般这么写：
    if(e.node){
                               i.store.getSubItemsByPId(e.node.id, e.node.layer + 1, function (e) {
                                            console.log(e);
                                            t(e)
                                        })
                                    }
                                    else{
                                        var rootnodes = i.store.getRootNodes();
                                        console.log("rootnodes:"+rootnodes)
                                        t(rootnodes)
                                    }
