前台选择
function Resultdata2(jsondata) {
        var listRecord = new Array();
        if (jsondata instanceof Ext.data.Store) {

            Ext.each(jsondata.data.items, function (record) {

                listRecord.push(record.data);
            });
        }
        else if (jsondata instanceof Array) {
            Ext.each(jsondata, function (record) {

                listRecord.push(record.data);
            });
        }//decode
        return Ext.encode(listRecord);
    }
