I checked Sina's js code today and found a rear-projection advertising code, which is good from both a learning perspective and a usage perspective. However, I found a problem and it will be blocked.
The following is the specific js code

Copy the code The code is as follows:

/* 
Carousel rear projection RotatorPB v3.1 
Update by Dakular  2008-8-25 
Format: new RotatorPB (Ad array) 
Description: Randomly appear on the first visit, and rotate in order on subsequent visits; automatically filter out expired ads; cookie time is 24 hours; do not display when the number of commercial ads is insufficient
