extjs – 立即加载TreeStore. Etxjs 4

我的问题是:如何立即加载TreeStore?

因为现在,如果我使用代理,获取Tree,在渲染之后,当我展开叶子时,还有一个请求使用GET参数’node’ – 叶节点的id.所以我需要用这个叶子的树来响应…但是我想立刻加载所有树而不再需要那棵树.

现在我有这些代码:

    Ext.define('AdminPanel.TreeNavigation', {              
        extend: 'Ext.data.Model',  
        fields: ['id', 'text', 'leaf', 'children']  
    });


    var store = Ext.create('Ext.data.TreeStore', {

                    model: 'AdminPanel.TreeNavigation',  

                    proxy: {  
                        type: 'ajax',
                        url : 'admin/getTreeNav',
                        reader: {
                            type: 'json',
                            root: 'result'
                        }
                    },

                    root: {
                        expanded: true
                    }

                });

最佳答案 在商店中,我将读者根设置为“结果”.

但是在json_data中我发送了’children’属性,就像那样:

{
    "result": [{
        "text": "\u041d\u043e\u0432\u043e\u0441\u0442\u0438",
        "leaf": true,
        "children": []
    }, {
        "text": "\u0410\u043a\u0446\u0438\u0438",
        "leaf": true,
        "children": []
    }, {
        "text": "\u041f\u043e\u043b\u044c\u0437\u043e\u0432\u0430\u0442\u0435\u043b\u0438",
        "leaf": true,
        "children": []
    }, {
        "id": "lang",
        "text": "\u042f\u0437\u044b\u043a",
        "leaf": false,
        "children": [{
            "text": "\u041a\u043e\u043d\u0441\u0442\u0430\u043d\u0442\u044b",
            "leaf": true,
            "children": []
        }]
    }]
}

但需要这样:

{
    "result": [{
        "text": "\u041d\u043e\u0432\u043e\u0441\u0442\u0438",
        "leaf": true,
        "result": []
    }, {
        "text": "\u0410\u043a\u0446\u0438\u0438",
        "leaf": true,
        "result": []
    }, {
        "text": "\u041f\u043e\u043b\u044c\u0437\u043e\u0432\u0430\u0442\u0435\u043b\u0438",
        "leaf": true,
        "result": []
    }, {
        "id": "lang",
        "text": "\u042f\u0437\u044b\u043a",
        "leaf": false,
        "result": [{
            "text": "\u041a\u043e\u043d\u0441\u0442\u0430\u043d\u0442\u044b",
            "leaf": true,
            "result": []
        }]
    }]
}

因此,Tree将在TreePanel上加载所有数据.
