PreventDefault() again.....

Its just not working. I have tried twice, cleared browser cache, chrome and safari, workspaces and Atom. No Dice.

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

//1. Capture the click event on a link to an image $("#imageGallery a").click( function( event ){ event.preventDefault(); var href = $(this).attr("href"); console.log();

//1.1 Show the overlay. //1.2 Update overlay with the image linked in the link //1.3 Get child's alt attribute and set caption

});

Please provide us with your full javascript code.

I have been running into the same problem. I'm convinced there is something up with the workspace. When I download the files and work in a text editor it works fine. If I copy that same exact code into the workspace, it fails. The weird thing is that it is working for some people and not for others. So I guess the best solution would be to work in a text editor, which is probably where we should all be doing this stuff anyway.

Maybe you've already figured it out, but the code you posted above needs the href passed to the console.log() function:

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

//1. Capture the click event on a link to an image $("#imageGallery a").click( function( event ){ event.preventDefault(); var href = $(this).attr("href"); console.log( href );

//1.1 Show the overlay. //1.2 Update overlay with the image linked in the link //1.3 Get child's alt attribute and set caption

});

The solution for the task you linked to is this anyway:

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

//1. Capture the click event on a link to an image
$("#imageGallery a").click(function(event){
  event.preventDefault();
  var href = $(this).attr('href');
  console.log(href);
  //1.1 Show the overlay.
  //1.2 Update overlay with the image linked in the link
  //1.3 Get child's alt attribute and set caption


});
//2. Add overlay
  //2.1 An image
  //2.2 A caption
//3. When overlay is clicked
  //3.1 Hide the overlay

The solution doesn't help me. Giving me the answers doesn't show me why mine didn't work. What I posted was the full JavaScript to that point in the project. The same point everyone else was having trouble.

But there really wasn't much to it, even to explain. You have two steps here to accomplish the task, preventDefault and assign href attr to href variable.

And your code works, it passes both steps, all i've done is reformatted it.

Yeah, I knew there wasn't much to it. But it wasn't and still doesn't work for me. That's why it so frustrating. Apparently I'm not the only one with this issue.

I'm struggling with this issue as well. It's a big time waster and still no answers. I'm wondering, can anyone recommend an alternative text editor?

Thanks, I suppose I'll just move on.
