Question

What is the best way to remove a class from an element upon successful completion?

How can I make an image disappear when the user clicks a button in the associated form? I'm struggling to implement this feature. Any suggestions?

    <script type="text/javascript">
   $(document).ready(function() {
       $(".removebutton").submit(function(event){

       event.preventDefault();
            $.ajax({
                 type:"POST",
                 url:"/munch_video/",
                 data: {
                        'video_id': $('.video_id', this).val(), // from form
                        'playlist': $('.playlist').val(), // from form
                        'add_remove': $('.add_remove').val(), // from form 
                        },
                 success: function(message){                         
                        alert(message);
                        $('.span8').removeClass('.video_id', this);

                    }
            });
            return false;
       });

    });

Answer №1

Initially, make sure to include the event.preventDefault(); line at the beginning to prevent default execution. This will stop the default behavior.

Focus on incorporating the return statement effectively.

When using removeClass, there is no need to add any additional parameters. Simply use the following code snippet:

$this.closest('.image').remove();

Here, $this serves as a saved reference to $(this).

It seems that elements with the classes span8 and video_id are missing. Double-check all elements or provide the complete code snippet.

Lastly, ensure that the PHP code is error-free and generating the correct results.

Consider implementing the following code snippet:

$(".removebutton").submit(function(event){
    var $this = $(this);
    $.ajax({
         type:"POST",
         url:"/munch_video/",
         data: {
                'video_id': $('.video_id', this).val(), // from form
                'playlist': $('.playlist').val(), // from form
                'add_remove': $('.add_remove').val(), // from form 
                },
         success: function(message){                         
                alert(message);
                $this.closest('.image').remove();
            }
    });
    event.preventDefault();
    return false;
});

Answer №2

$('.span8').removeClass('video_id')

ensuring no period in class parameters

Update: Requested removal of an image from a container

$('.span8').find('img').remove()

for removing all images within the container,

$('.span8').find('img.video_id').remove()

to specifically remove images with the video_id class,

if you prefer to simply hide the element

$('.span8').find('.video_id').hide()

Answer №4

The sudden disappearance of the image puzzles me as there seems to be no alteration in its display settings. How about trying the following approach:

$('.span8').removeClass('video_id').addClass('vanish');

Also, don't forget to include the CSS rule .vanish { display:none; } in your stylesheet.

Answer №5

To begin, I would suggest starting with the .removeClass() function. It should only have one argument; the use of this is unnecessary. Also, remember that the class name should not have a period in front of it.

//$('.span8').removeClass('.video_id', this);
$('.span8').removeClass('video_id');

Update: It seems like you may need to refine your element selection. Assuming you have a button and an image within a <div class="span8">, the structure would look something like this:

<div class="span8">
    <img src="cat.jpg" />
    <a href="#" class="removebutton">remove</a>
</div>

In that case, you would need to navigate from the clicked element to the parent div and then find the image within it.

$(this).closest('.span8').find('img').remove();

addClass() requires the class name, not the class selector. Essentially, you need to omit the dot.

$('.container').addClass('new_class');
