JavaScript jQuery Basics (2014) Creating a Simple Lightbox Fixing the Simple Lightbox

Glitch or am I wrong?

Last Challenge in jQuery. The goal is to change ("alt") to ("title") which I have done. Rather than passing it says that task one is not passing which is doing the preventDefault to negate a dead end link. I have checked the board and my code is just like others that have passed. Am I missing something?

js/app.js 
//Problem: User when clicking on image goes to a dead end
//Solution: Create an overlay with the large image - Lightbox

var $overlay = $('<div id="overlay"></div>');
var $image = $("<img>");
var $caption = $("<p></p>");

//An image to overlay
$overlay.append($image);

//A caption to overlay
$overlay.append($caption);

//Add overlay
$("body").append($overlay);

//Capture the click event on a link to an image
$("#imageGallery a").click(function(){
  event.preventDefault();

  var imageLocation = $(this).attr("href");
  //Update overlay with the image linked in the link
  $image.attr("src", imageLocation);

  //Show the overlay.
  $overlay.show();

  //Get child's title attribute and set caption
  var captionText = $(this).children("img").attr("title");
  $caption.text(captionText);
});

//When overlay is clicked
$overlay.click(function(){
  //Hide the overlay
  $overlay.hide();
});

Hi Brian,

The original starter code had the event object as a parameter to the anonymous function. It looks like you took that out.

$("#imageGallery a").click(function(event){
