php-laravel - The problem of comparing the size of two input values in form validation in laravel

Question

The problem is this. I now have two input boxes with input values. During verification, I need to compare the values ​​of the two input boxes. If the value passed in box A is greater than the value passed in box B, an error will be returned. It cannot pass. It seems that using Max:value or min:value does not work. I would like to ask how to compare such verification.

You can use js directly to capture input events, obtain values, compare, and output error messages;
To be more secure, it is OK to set a judgment when submitting in the background.
