问题描述

我正在使用这篇架构文章http://blog.extjs.eu/know-how/writing-a-big-application-in-ext/

I am using this article of architecture http://blog.extjs.eu/know-how/writing-a-big-application-in-ext/

这是我的 Application.ResellerGrid.js

Here is my Application.ResellerGrid.js

Application.ResellerGrid = Ext.extend(Ext.grid.GridPanel, {
    border:false
    ,cityname : ''
    ,columndataindex : ''
    ,fromdate:''
    ,todate : '' 
    ,initComponent:function() {
        var config = {
            store:new Ext.data.GroupingStore({
                // store configs
                autoDestroy: true,
                autoLoad :false,
                url: 'api/index.php?_command=getresellers&city='+this.cityname+'&columndataindex='+this.columndataindex
                +'&fromdate='+this.fromdate+'&todate='+this.todate
                ,
                storeId: 'getresellerscount',
                // reader configs

                    dataIndex: 'alloctype'
                },
                {
                    id       :'apptype',
                    header   : ' apptype',

            ]
            ,view: new Ext.grid.GroupingView({

                groupTextTpl: '{text} ({[values.rs.length]} {[values.rs.length > 1 ? "Items" : "Item"]})'
            })
            ,plugins :[]
            ,viewConfig :{forceFit:true}
            ,tbar :[]
            ,bbar :[]
            ,height : 250
            ,width : 860
            ,title : 'Reseller Grid'
        }; // eo config object

        // apply config
        Ext.apply(this, Ext.apply(this.initialConfig, config));

        Application.ResellerGrid.superclass.initComponent.apply(this, arguments);
    } // eo function initComponent
    ,onRender:function() {
        this.store.load();

        Application.ResellerGrid.superclass.onRender.apply(this, arguments);
    } // eo function onRender
});

Ext.reg('ResellerGrid', Application.ResellerGrid);

这是我的json响应

    {
    "reseller": [{
        "firstname": "anusha",
        "lastname": "",
        "mobile": "9739949891",
        "email": "",
        "tmecode": "010739",
        "tmename": "Deepa S",
        "updatedon": "2011-03-18 13:17:22",
        "apptype": "1",
        "alloctype": "2",
        "empparent": "Bangalore",
        "parentname": "HEMARLI"
    }, {
        "firstname": "IBRAZ",
        "lastname": "",
        "mobile": "9740834768",
        "email": "",
        "tmecode": "010739",
        "tmename": "Deepa S",
        "updatedon": "2011-03-18 17:52:04",
        "apptype": "1",
        "alloctype": "2",
        "empparent": "Bangalore",
        "parentname": "HEMARLI"
    }, {
        "firstname": "manjunath",
        "lastname": "",
        "mobile": "7829407211",
        "email": "[e-mail]",
        "tmecode": "012574",
        "tmename": "Geetha S",
        "updatedon": "2011-03-19 17:12:17",
        "apptype": "1",
        "alloctype": "2",
        "empparent": "Bangalore",
        "parentname": "HEMARLI"
    }]
}

我的网格中的数据没有显示为什么?

data in my grid is not showing why ?

推荐答案

通过添加 jsonreader 完成，没有 jsonreader 分组存储不起作用.

Done by adding jsonreader , grouping store doesn't work without jsonreader .
