Detect internet connection in cross browser platform

Question

I need to detect internet connection in my js file. i used Navigator.Online but it is not reliable especially in the Firefox and Safari. Only chrome seems to return right output. I also came across wonderful jquery plugin checkNet but after analyzing it, i found it is only checking for server not for internet because when i run it in local it checks it from xammp server

this are the links which i used for reference
