我有一个树视图,它从树存储中获取其数据。但是,我只能看到作为树结构一部分显示的小文件夹。没有显示节点的名称,当我尝试打印记录时,它只是说它是一个空字符串。这是代码:
应用程序/视图
Ext.define('App.view.Hierarchy', {
    alias: 'widget.hierarchy',
    extend: 'Ext.panel.Panel',
    initComponent: function () {
        var config = {
            xtype: 'panel',
            border: false,
            autoScroll: true,
            baseCls: 'topMenu',
            html: '<div class="PageTitle" style="width:600px;"><b>' + LANG.HIERARCHYT + '</b><br>' + LANG.HIERARCHYTxt + '<br>' + '</div>',
            items: [{
                xtype: 'toolbar',
                border: false,
                dock: 'top',
                items: [{
                    xtype: 'button',
                    text: LANG.BTADDREG,
                    iconCls: 'icon-add-tb',
                    cls: 'tip-btn',
                    iconAlign: 'right',
                    action: 'addRegion',
                    id: 'ADDREGION'
                }]
            },
            {
                xtype: 'treepanel',
                title: 'Hierarchy Tree',
                id: 'hierarchyTree',
                border: false,
                alias: 'widget.hierarchyTree',
                height: 1000,
                viewConfig: {
                    enableDD: true,
                    plugins: {
                        ptype: 'treeviewdragdrop'
                    }
                },
                collapsible: false,
                useArrows: true,
                rootVisible: false,
                store: Ext.create('Campus.store.HierarchyTree'),
                displayField: 'Title',
                multiSelect: false,
                singleExpand: false,
            }]
        }
        var holder = Ext.getCmp('center');
        holder.remove(0);
        holder.add(Ext.apply(config));
        this.callParent(arguments);
    }
});
模型
Ext.define('App.model.HierarchyTree', {
    extend : 'Ext.data.Model',
    fields : ['Title', 'ID', 'LevelID', 'ParentID'] 
});
店铺
Ext.define('App.store.HierarchyTree', {
    extend: 'Ext.data.TreeStore',
    model: 'App.model.HierarchyTree',
    storeID: 'HierarchyTree',
    proxy: {
        type: 'ajax',
        url: 'data/Locations.aspx',
        reader: {
        },
        actionMethods: {
            create: 'POST',
            read: 'POST',
            update: 'POST'
        },
        extraParams: {
            mode: 'HIERARCHYFULLLIST'
        }
    },
    autoLoad: true
});
控制器
Ext.define('App.controller.Hierarchy', {
    extend: 'Ext.app.Controller',
    stores: ['Me', 'Regions', 'Areas', 'Towns', 'HierarchyTree'],
    model: ['Me', 'Teams', 'Regions', 'User', 'HierarchyTree'],
    views: ['App.view.Hierarchy', 'App.view.AddRegions'],
    refs: [{
        ref: 'myHierarchyTree',
        selector: 'hierarchyTree'
    }],
    init: function () {
        this.getHierarchyTreeStore().load();
        this.control({
            'button[action=addRegion]': {
                click: this.addRegion
            },
            '#hierarchyTree': {
                itemclick: this.itemclick
            }
        })
    },
    itemclick: function (view, record) {
        console.log(record.get('Title'))
    }
});
此外,返回的 JSON 是:
{"text":".","children": [{"text":"Asia Pacific","id":"537","level":"1", "expanded": 
 false,"singleClickExpand":true,"children":[{"text":"Japan", "cls":"xtreenode-Level2-
Indent", "id":"538", "hl1":"537","level":"2","singleClickExpand":true, "expanded":   
false, "children":[]},
