In our Jenkins job, I used a javascript to manage how to hide/show the parameters base on certain parameter.

For example, from the dropdown list, if I choose A, parameters A1, A2 will be shown but parameter B1, B2 will be hidden.

Or if I choose B, parameters B1, B2 will be shown and paramters A1, A2 will be hidden.

 

Everything is fine until I upgrade to Jenkins version 2.303.1. Now it didn't work with this Jenkins version. All parameters is now shown no matter I choose A or B.
