Detect internet connectivity using JavaScript or jQuery?

Question

I want to check if internet is available or not when the web page loads. I want to do this in order to:

disable like buttons request if offline, during development
load local links if no network, otherwise load from HTTP
call more data from server in appcache based offline apps only if user is online

How do I achieve this?

The window.navigator object has an online property that you can use:

Alternatively you can make a quick Ajax request and check the error code you receive.
