******************** 解决方案 [C #][ASP.NET][WebForm] How to avoid the screen flash?Q1 election A time, Q2 can not be edited;Q1 election B, Q2 can be edited;Because it is PostBack, click the screen will flash.(The origion webpage is a more complex webpage, I cut out two fields to make a small program, so it maybe not see the flash of the situation)Question 1: want to use front-end JavaScript to solve the flash situation, but I look at HTML Source, which seems to be already a JavaScript? (Or not?)Question 2: Is there a good way to avoid flashing for this problem?
