grid 加载后台数据不成功？

Question

var jydbh = Ext.getCmp("jydbh").getValue();
        alert(jydbh);//这边有数据
         var ds = new Ext.data.Store({
                        proxy: new Ext.data.HttpProxy({url:"URL/jydbh/GetHwxx.aspx?jydbh='"+jydbh+"'"}),

        Response.End();result返回值为:['茶具','1','32.0000','0.0000','320.0000','0.0000','0.0000','320.0000','30.0000','3000.0000','0.002','6.0000','0.0000','356.0000']

Answer 1

返回的不是茶具 是杯具
result显然是 数组结构，所以对应的store必须是ArrayStore, 或者普通Store带一个ArrayReader。而你用的JsonReader，所以result就得是json格式的(具体看api上例子)。
改前台还是后台你看着办吧。

Answer 2

 var ds = new Ext.data.Store({
                        proxy: new Ext.data.HttpProxy({url:"URL/jydbh/GetHwxx.aspx?jydbh='"+jydbh+"'"}),
                        reader: new Ext.data.ArrayReader({}, [
                            { name: 'hwmc' },
                            { name: 'js' },
                            { name: 'tj' },
                            { name: 'zl'},
                            { name: 'djj' },
                            { name: 'djf' },
                            { name: 'djd' },
                            { name: 'cyf'},
                            { name: 'hk' },
                            { name: 'bxe' },
                            { name: 'bxfl' },
                            { name: 'bxf' },
                            { name: 'jhf' },
                            { name: 'hwzyf' }                        ]),
                        sortInfo: { field: "hwmc", direction: "ASC" }
                    });
                    ds.load();
我改为以上那样也不行啊！  谁给看看

                    ds.load();我改为上面那样也不行啊

                    ds.load();我改为这样也不行啊

Answer 5

给你个ArrayReader的标准例子，自己参考下改一改后台和前台。
var data = [
[’茶具'],
['1']
];
var reader = new Ext.data.ArrayReader({
id:1  //可以注释此句
},[
{name:'hwmc' ,mapping:0},
{name:'js' ,mapping:1}
]);

Answer 6

        var jydbh = Ext.getCmp("jydbh").getValue();          var ds = new Ext.data.Store({
                        proxy: new Ext.data.HttpProxy({url:"URL/jydbh/GetHwxx.aspx?jydbh='"+jydbh+"'"}),
                        reader: new Ext.data.JsonReader({}, [
                            { name: 'hwmc' },
                            { name: 'js' },
                            { name: 'tj' },
                            { name: 'zl'},
                            { name: 'djj' },
                            { name: 'djf' },
                            { name: 'djd' },
                            { name: 'cyf'},
                            { name: 'hk' },
                            { name: 'bxe' },
                            { name: 'bxfl' },
                            { name: 'bxf' },
                            { name: 'jhf' },
                            { name: 'hwzyf' }                        ]),
                        pruneModifiedRecords:true,
                        sortInfo: { field: "hwmc", direction: "ASC" }
                    });
                    ds.reload();
        
我用这个传递jydbh 参数 去后台取值  
后台返回的值为['茶具','1','0.0000','32.0000','320.0000','0.0000','0.0000','320.0000','30.0000','3000.0000','0.002','6.0000','0.0000','356.0000']怎么赋值给eidtorgrid呢？  用load()不行啊

Answer 7

仔细看api上ArrayReader例子
返回值要的是这种格式， 二维数组， 外面一维是由于ArrayReader，需要读Array格式数据， 里面一维用来标示一条数据
[ [1, 'Bill', 'Gardener'], [2, 'Ben', 'Horticulturalist'] ]
