grid加載JSON數據至store中

//頁面彈窗

var win = new Ext.Window({
            layout:'fit',
            width:1020,
            height:600,
            closeAction:'hide',
            items:[confirm],//在彈窗中嵌套表格;
            modal:true,
            listeners : {
                 'hide':function(){
                     store.reload();
                 },
                    'show':function(){
                 }
             },
            buttons:[
                {
                    text:'確認',
                    handler:function(){
                    }
                },{
                    text:'取消',
                    handler:function(){
                        win.hide();
                    }
                }]
        });

//設定grid格式

var confirm = new Ext.grid.GridPanel({
            store:personStore,
            columns:[
                {header:"商品編號",dataIndex:"Meta_productNo",width :100,align:'left',resizable:true,sortable:true },
                {header:"商品名稱",dataIndex:"Meta_productName",width :100,align:'left',resizable:true,sortable:true },
                {header:"商品屬性",dataIndex:"Meta_attribute",width :100,align:'left',resizable:true,sortable:true },
                {header:"SKU編號",dataIndex:"Meta_sku",width :100,align:'left',resizable:true,sortable:true },
                {header:"SKU顏色",dataIndex:"Meta_color",width :100,align:'left',resizable:true,sortable:true },
                {header:"SKU規格",dataIndex:"Meta_standard",width :100,align:'left',resizable:true,sortable:true },
                {header:"進貨價(元)",dataIndex:"Meta_buyingPrice",width :100,align:'left',resizable:true,sortable:true},
                {header:"批發價(元)",dataIndex:"Meta_tradePrice",width :100,align:'left',resizable:true,sortable:true },
                {header:"零售價(元)",dataIndex:"Meta_retaillPrice",width :100,align:'left',resizable:true,sortable:true },
                {header:"平臺評估價(元)",dataIndex:"Meta_appraisePrice",width :100,align:'left',resizable:true,sortable:true },
            ],
            layout:'fit'
        });

//設定JsonStore

var personStore = new Ext.data.JsonStore({
            method : "POST",
            fields : ["Meta_productNo","Meta_productName","Meta_attribute","Meta_sku","Meta_color","Meta_standard","Meta_buyingPrice","Meta_tradePrice","Meta_retaillPrice","Meta_appraisePrice"]        //與Grid1列一致，至少列名稱一致
        });

//重頭戲=======加載後臺json數據彈窗展示

var data = Ext.util.JSON.decode(response.responseText);
personStore.loadData(data);
win.show();

//後臺的json格式直接返回跟JsonStore中的格式一樣,無需前綴！
