Question

While I have the ability to include an overlay, I unfortunately lack the capability to delete it using jQuery

This feature will create an overlay on the entire browser screen using the defined properties.

$('a.cell').click(function()    {
    $('<div id = "overlay" />').appendTo('body').fadeIn("slow");
});

#overlay
{
background-color: black;
width: 100%;
height: 100%;
position: fixed;
top: 0;
left: 0;
display: none;
z-index: 100;
opacity: 0.5;
}

Then, there is a function to remove this overlay.

$('#overlay').click(function()  {
    $(this).fadeOut("slow").remove();
});

However, the removal function does not seem to be working correctly and now the page is stuck with a black overlay. What could be causing the issue?

Answer №1

The issue arises when trying to add a click handler without any overlay present, resulting in the handler being attached to an empty set of elements.

A solution is to utilize the live method to bind the handler to all elements matching #overlay as they are created.

Furthermore, it's important to note that fadeIn is not a blocking call, meaning it returns before the element finishes fading out. Consequently, calling remove immediately after initiating the fade-out may cause issues.

To avoid this problem, make use of the callback parameter in the fadeOut function to ensure that remove is executed only after the animation has completed.

Here's an example of how to implement this:

$('#overlay').live(function() { 
    $(this).fadeOut("slow", function() { $(this).remove(); });
});

Here is the solution to resolve this issue: simply add the code below in your script so that the overlay can smoothly fade out before being removed.

$('#overlay').on("click", function()  {
        $(this).fadeOut("slow", function() { $(this).remove() });
});

It is best practice to include the removal within the fadeOut callback, as shown below:

$('#popup').on('click', function()  {
    $(this).fadeOut("slow", function() {
       $(this).remove();
    });
});

If you're looking for a great solution for overlays, I highly recommend checking out the jquery.tools overlay plugin. With this plugin, you can easily create an overlay with a trigger such as a button or link, and control it using JavaScript commands like the ones below:

JavaScript:

var settings = { closeOnClick:true, mask:{opacity:0.7, color:'#333', loadSpeed:1} }
$("#myTrigger").overlay(settings); // enable overlay functionality
$("#myTrigger").data("overlay").load(); // display the overlay
$("#myTrigger").data("overlay").close(); // hide the overlay

HTML:

<div id="myOverlay" style="display:none;">Make sure to specify width and height in CSS.</div>
<button id="myTrigger" rel="#myOverlay">show overlay</button>
