Erasing a comment creates empty spaces

Erasing a comment creates empty spaces

I've encountered an issue with my idea whiteboard where removing comments leaves unwanted blank spaces between ideas.

For example, if I have the following comments:

But when I delete something:

Is there a way to ensure that no gaps are left between comments?

Here's the current code snippet I'm working with:

jQuery(function ($) {

    $('#chat').on('click', '.delete', function(e) {
        $(this).parent().remove();
    });

    var socket = io.connect();
    var $messageForm = $('#sendmessage');
    var $messageTitle = $('#title');
    var $messageBox = $('#message');
    var $chat = $('#chat');

    $messageForm.click(function (e) {
        if ($.trim($("#title").val()).length === 0) {
            alert('You must provide valid input');
            $messageTitle.val('');
            $messageBox.val('');
            return false;
        }
        if ($.trim($("#message").val()).length === 0) {
            alert('You must provide valid input');
            $messageTitle.val('');
            $messageBox.val('');
            return false;
        } else {
            e.preventDefault();
            socket.emit('send message', '<span class="idea"><b>' + $messageTitle.val() + '</b>' + '&nbsp;-&nbsp;' + $messageBox.val() + '&nbsp;' + '[' + '<a class="delete" href="#">Delete</a>' + ']</span>');
            $messageTitle.val('');
            $messageBox.val('');
        }
    });

    socket.on('new message', function (data) {
        $chat.prepend(data + "<br/>");
    });
});

The HTML without any blanks:

<div id="chat"><span class="idea"><b>sfdf</b>&nbsp;-&nbsp;czxczxc&nbsp;[<a class="delete" href="#">Delete</a>]</span>
    <br><span class="idea"><b>dsdfsd</b>&nbsp;-&nbsp;sdfsdfsdf&nbsp;[<a class="delete" href="#">Delete</a>]</span>
    <br>
    <br><span class="idea"><b>dsfsdf</b>&nbsp;-&nbsp;sdfsdf&nbsp;[<a class="delete" href="#">Delete</a>]</span>
    <br>
</div>

Instead of using <br> tags to separate different ideas, a cleaner approach would be to implement a CSS rule that places each idea on its own line.

<style>span.idea { display: block }</style>

With this change, the following code:

$chat.prepend(data + "<br/>");

can be simplified to:

$chat.prepend(data);

It is important to ensure you have properly sanitized the data variable in order to prevent any potential cross-site scripting (XSS) attacks.

In my opinion, it is best to utilize the 'remove' function rather than 'empty'.

Using 'empty' simply clears out the content of an element without removing it entirely.

It seems like the issue lies with the
tag that is still in the DOM, inserted using this code:

$chat.prepend(data + "<br/>");

To resolve this, consider using a list structure instead:

<ul>
    <li class="id">message1</li>
    <li class="id">message2</li>
</ul>

You will need to modify these lines of code:

socket.emit('send message', '<li class="idea"><b>' + $messageTitle.val() + '</b>' + '&nbsp;-&nbsp;' + $messageBox.val() + '&nbsp;' + '[' + '<a class="delete" href="#">Delete</a>' + ']</li>');

Replace the line below with this:

$chat.prepend(data);

Additionally, add the following lines at the beginning:

var chatUlElement = $('ul');
var $chat = $('#chat').append(chatUlElement);
