Does jQuery work on Internet Explorer 8?
Yes! It looked like IE 8 is a source of problem but it is not.
Security setting is a reason why jQuery doesn't work. Active scripting must be enabled. It was disabled and because problem listed in this article appeared.
To enable Active scripting:
Click Tools --> Internet Options --> Security tab
Select Internet zone (world globe) --> Click Custom level
Click on Enable Active Scripting and clik OK.
