[SOLVED] event.preventDefault() stopped working?

Hey guys, I need another pair of eyes. Everything was working fine until I added a code that ads caption to the image. After doing that my browser seems to be ignoring event.preventDefault() method and it's taking me to a dead end. I double checked and everything seems to be fine. Please help me out, it's so frustrating.

Here's my code, maybe You guys can find a bug. Thanks!

// Problem: user when clicking on image goes to a dead end=poor UE
// Solutioin: create an overlay with the large image - Lightbox
var $overlay = $("<div id="overlay"></div>");
var $image = $("<img>");
var $caption = $("<p></p>");

// Add umage to overlay

// Add caption to overlay

// Add an overlay

// Capture the click event on a link to an image
$("#imageGallery a").click(function(event){
    var imageLocation = $(this).attr("href");
  // Update overlay with the imge linked in the link
    $image.attr("src", imageLocation); 

  // Show the overlay  

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


//3. When overlay is clicked 
$overlay.click(function() {
  //3.1 Hide the overlay.

One issue that i see is your $overlay variable var $overlay = $("<div id="overlay"></div>");

When you require quotes within your jQuery selector you have to either use single quotes on the attribute value or escape the double quotes...

var $overlay = $("<div id='overlay'></div>");


var $overlay = $("<div id=\"overlay\"></div>");

Hope that helps :thumbsup:

Hi Chris,

indeed, that was the issue! Normally I use single quotes but because I am a novice and saw in the video that Andrew was using double quotes, I decided to change them all and forgot to use backslash. So silly mistake!

Thanks a lot for your help!
