I tried to find how to get the altitude above the mean sea level. At this time, it returns altitude from the ellipsoid. So, anyone knows the formula or calculation to change the altitude value from ellipsoid to the altitude value from mean sea level. Thank you for all help

I am developing web app that will be accessed by smart-phone integrated browser. In my application I need to calculate the distance between the mobile phone actual (current) location and some other address. Beside that I should be able to find the specific location (shop location for example) that is closest to the user actual location. Can you give me a clue which js framework can I use? Is there maybe some jQuery plugin that can be helpful? Thank you
