Question

                {
                    title: '天数', field: 'ChiD', width: 120, formatter: function (value, row, index) {
                        var CD1 = "";
                        CD1 = value;
                        var CMingX = [];
                        CMingX = CD1.split(",");
                        value = "";
                        for(var c=0;c<CMingX.length-1;c++)
                        {
                            value += CMingX[c] + "\n";
                        }
                        return value;
                    }


    value =" 总计：8 天,2015-07-01,2015-07-02,2015-07-03,2015-07-06,2015-07-07,2015-07-08,2015-07-09,2015-07-10,"



    目的 = 总计：8 天
                        2015-07-01
                        2015-07-02
                        2015-07-03
                        2015-07-06
                        2015-07-07
                        2015-07-08
                        2015-07-09
                        2015-07-10

    现在报错：Uncaught TypeError: Cannot read property 'split' of undefined

你把那个value toString看看呢 感觉类型问题吧
