Check online/offline

Hi,
How can I check using javascript that I'm working online/offline(I'm using IE).
When the user clicks on a button and he has clicked/selected (Files--->WorkOffline),then,I should display an alert box like "Can't perform operations when you are offline".
Any ideas/suggestions will be greatly helpful for me.Thanks in advance.
