MY JS

$scope.showModal = function(templateUrl) {
$ionicModal.fromTemplateUrl(templateUrl, {
scope: $scope,
animation: ‘slide-in-up’
}).then(function(modal) {
$ionicLoading.show({
duration: 1000
});
$scope.modal = modal;
$scope.modal.show();
});
}

// Close the modal
$scope.closeModal = function() {
    $scope.modal.hide();
    $scope.modal.remove()
};

$scope.showFile = function(FileUrl) {
    var file = FileUrl;
    console.log(file);
    //var openurl = cordova.InAppBrowser.open(file, '_blank');
  //  var openurl = cordova.InAppBrowser.open(file,'_blank', 'location=yes');

      // var openurl = cordova.InAppBrowser.open("https://docs.google.com/viewer?url=" + file, '_blank');

// var openurl = cordova.InAppBrowser.open('https://docs.google.com/viewer?url=http://www.orimi.com/pdf-test.pdf&embedded=true', '_blank');

      //window.open("https://docs.google.com/viewer?url=http://www.orimi.com/pdf-test.pdf&embedded=true",'_blank');


var openurl = cordova.InAppBrowser.open('https://docs.google.com/viewer?url=http://www.orimi.com/pdf-test.pdf&embedded=true&toolbar=0&navpanes=0&scrollbar=0', '_blank');
