dataTables onCellRender问题

棒棒糖

Model.prototype.dataTables1CellRender = function(event){
        if(event.colName == "fPrjName"){
              var sql = "select t1.fPrjName AS fPrjName from OA_OvertimeApplication t1 where t1 = (select t.fMasterID AS fID from OA_OvertimeApplicationInfo t where t = '" + event.rowID +    "')";                PM.loadTableByKsql(this.comp("dataTemp"),sql,this.getContext(), "/OA/overtimeApplication/data");
              var fPrjName = this.comp("dataTemp").getValue("fPrjName");
              alert(fPrjName);//得到的是undinfined
        }
       
};
从数据库里查值事由的为什么在这里得到的却是undinfined的

this.comp("dataTemp").toJson()看看是什么
