Stanleek,
Sorry that you are seeing this issue. I could not replicate the problem at my end with a javascript file in latest MyEclipse 2017 CI 7.
Do you see the problem with a particular javascript file or all javascript files in the workspace? Can you please check if there are any errors logged in the Error Log view when you try to click on the listed functions?
Please check if the issue persists in a new workspace as well. Also share us the .log file located at workspace dir/.metadata/.log along with the OS and version details for further investigation.
Apologies for inconvenience caused.
–Swapna
