Cordova - Checking WIFI connection to internet

Question

I use Cordova to develop a smartphone application.

In this app, I need to check the internet connection before send request to a server.

In order to do that I use the Cordova Connection API, but in the case that the device is connected to a WIFI network with no Internet connection, this API say that we have WIFI connection,

is there any way to check if internet is available on the WIFI network ?

Answer 1

Send an Dummy ajax request before you send the actual request, If you get and Error Code as '0' it means there is no internet connectivity.

$.ajax({
    url: 'TestUrl',
    type: 'GET',
    success: function (data) {
                // Go ahead with you request
    },
    error: function (x, y, z) {
        if (x.status == 0) {
            alert("Please connect to the internet");
        }
       else{
           alert("Other Error Occured")
        }
    }
});

Secondly you can also make you of HTML 5 navigator

var condition = navigator.onLine ? "ONLINE" : "OFFLINE";
