    var options = "location=no,zoom=no"

   //   var ref = window.open(url, target, options, option1);

    ref.addEventListener('loadstart', loadstartCallback);
    ref.addEventListener('loadstop', loadstopCallback);
    ref.addEventListener('loadloaderror', loaderrorCallback);
    ref.addEventListener('exit', exitCallback);

    function loadstartCallback(event) {

        showSpinner();

    }

    function loadstopCallback(event) {
        hideSpinner();
    }

    function loaderrorCallback(error) {
        console.log('Loading error: ' + error.message)
    }

    function exitCallback() {
        console.log('Browser is closed...')
    }

    function showSpinner() {
        navigator.notification.activityStart("Bayar Speed Kart", "Its loading....");
        //  $.mobile.loading("show");
    }

    function hideSpinner() {
        navigator.notification.activityStop();
        //$.mobile.loading("hide");
    }

    // Handle the Cordova pause and resume events
    document.addEventListener( 'pause', onPause.bind( this ), false );
    document.addEventListener( 'resume', onResume.bind( this ), false );

    // TODO: Cordova has been loaded. Perform any initialization that requires Cordova here.
};

Once i too suffered from same proble how i solve the problem is by loading an gif image in loadstart method

        ref.addEventListener("loadstart", function () {

        ref.executeScript(
           // { code: "document.body.style.backgroundColor = 'yellow';" },
              { code: "document.body.style.background = 'url(loading.png)';" },
                // url("paper.gif");
           function (values) {
                //alert(values[0]);
            }
        );
    });
