Extjs Grid store加載數(shù)據(jù)不會出來，網(wǎng)絡(luò)跟蹤能夠開到數(shù)據(jù)已經(jīng)查詢到前臺，可是就不顯示，

});

修改后如下把JSONStore換成Store就出來了

var contract_selectItem_storeBudget = new Ext.data.Store({
        proxy: new Ext.data.HttpProxy({
            url: woo.constant.baseUrl+ "/AjaxPage/WooYuSuan/YusuanManager.aspx?cmd=list"
        }),
        reader: new Ext.data.JsonReader({
            totalProperty: 'totalProperty',
            root: 'List'
        }, contract_selectItem_readerBudget)
