Check Internet connectivity with jquery

Question

I am trying to check for the internet connection by sending a GET request to the server. I am a beginner in jquery and javascript. I am not using navigator.onLine

Answer 1

you cannot get simple true or false in return, give them a callback handler

function is_internet_connected(callbackhandler)
{
$.get({
  url: "/app/check_connectivity/",
  success: function(){
     callbackhandler(true);
  },
  error: function(){
     callbackhandler(false);
  },
  dataType: 'text'
});
}
