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

Do you mean to check the internet connection if it's connected?

If so, try this:

$.ajax({
    url: "url.php",
    timeout: 10000,
    error: function(jqXHR) { 
        if(jqXHR.status==0) {
            alert(" fail to connect, please check your connection settings");
        }
    },
    success: function() {
        alert(" your connection is alright!");
    }
});
