两个操作数为undefined或者null会报错 #20
Comments
@anglesh 内部没有加数值判断导致的错误,这个你最好在调用函数之前检测传入的参数是否都是数值 |
@anglesh 先将不是数值的做一次转换处理或者提前禁止计算 |
后面能加下数值判断吗,因为每次调用都要判断,有点麻烦 |
@anglesh 这个可能不好加,因为不知道出现 undefined、null 是要转换为 0 呢还是直接报错 |
那可以提供个参数供设置下吗,的确每次判断有点麻烦 |
@lhwu 预期需要处理的是什么样的数据? |
需要的是处理 undefined 的数据,常见的是本地开发时没碰到取值为undefined的数据,但是测试/生产时,数据可能取值到了 undefined(默认做0处理就行),导致报错。 而这时候需要再去对数据进行赋默认值操作,而且用到的地方比较多,每次操作都进行这个操作的话,比较烦杂。 所以觉得如果有个设置能统一处理下这种好。 |

同求,遇到null or undefined统一返回成NaN应该就行了吧 |
