Answer 1

Ajax异步请求，返回二维数组，JS中接受的值为null

$.ajax({
            url:'analyse_statistics.action',
            type:'post',
            dateType:'json',
            data:'statisticsType='+$(this).val(),
            success:function(data){
                if(data!=null){
                    alert(date);
                    for(var i=0;i<4;i++){
                        charts.series[i].setData(data[i]);
                    }
                }
            }
        });

后台返回二维数组，后台调试发现数组中有值，但JS中data=null,

dateType:'json'----------->dataType:'json'                                                                
data:'statisticsType='+$(this).val()    ------->          data:{'statisticsType':$(this).val()}
