The project has been released for a long time, and suddenly an error occurs. After researching it,
1 First of all, there should be no problem with the code, the test is passed and there is no abnormality in the local test for a long time
2 Considering that many styles have been added to the formal environment, the reasons are found in the styles, and the introduction of jquery in the formal environment leads to conflicts with the previous jquery version
To sum up, the debugging of the formal environment and the local environment should first debug the local environment and start with the different points to see if the local environment matches the formal environment.
