Hi, I just submitted my script to an website. I found this website just redirects to my web page in a parameter such as Does this link give PR?
No, it's a 302 redirect. Redirects can pass pagerank, but they have to be 301s You can use a tool like a http or header viewer to check what kind of redirect you are looking at - there are several free online ones
Only a 301 redirect can pass its pagerank through, the redirect you are talking about is commonly known as a 302 redirect and unfortunately page rank cannot be passed though!
