When working with tables , Write logic according to the data of the table , The result is that the data is wrong , The logic is also wrong . The reason why the data is wrong is that I started , Write the logic wrong , Modify again , Wrong result , The data is wrong . Next time, think calmly and write logic directly based on data .

In the front end of writing , Write the class wrong ~. It has been ineffective , There's no data .

reflection ： Don't type too fast ,
When it comes to transferring pages ,
Remember the parameters ,
In naming , Write short English characters
Calm down and analyze , Be serious

There will be mistakes in the future , It will be changed later , Like to see me make mistakes , You can pay attention to me ~
