How to loop foreach in blade while using jquery in Laravel

I'm using Laravel 5.4 and I have never tried jquery so I have no idea what I'm doing, unfortunately.

This is my blade:

<h3>Comments:</h3>
<ul class="list-unstyled activity-list">
    @foreach ($threads->comments()->where('parent', 0)->orderBy('created_at', 'desc')->get() as $comment)
        <li>
            <img src="" alt="Avatar" class="img-circle pull-left avatar">
            <p><a href=""> 
                </a>: 
                <br>
                
                <span class="timestamp"></span>
            </p>
            @if ($threads->lock == 0)
                <a id="btn-comment" style="padding-left:3.5em">reply</a>
                <br>
                <form action="" id="comment"  method="POST" style="padding-left:3.5em; display:none;">
                    
                    <input type="hidden" name="thread_id" value="">
                    <input type="hidden" name="parent" value="">
                    <input type="text" name="content" class="form-control" placeholder="Add reply...">
                    <input type="submit" class="btn btn-primary btn-xs" value="Add Reply">
                </form>
                <br>
            @endif
            @foreach ($comment->childs as $child)
                <div style="padding-left:3.5em;">
                    <img src="" alt="Avatar" class="img-circle pull-left avatar">
                    <p><a href=""> 
                        <span style="padding-left:1em;"></a>: </span>
                        <br>
                        <span style="padding-left:1em;"></span>
                        <span class="timestamp" style="padding-left:4.3em;"></span>
                    </p>
                </div>
            @endforeach
        </li>
    @endforeach
</ul>

Here's my custom script:

<script>
    $(document).ready(function(){
    $('#btn-comment').click(function(){
        $('#comment').toggle('slide');
        });
    });
</script>

These lines specifically are the ones that I'm trying to run using the script above:

@if ($threads->lock == 0)
    <a id="btn-comment" style="padding-left:3.5em">reply</a>
    <br>
        <form action="" id="comment"  method="POST" style="padding-left:3.5em; display:none;">
            
            <input type="hidden" name="thread_id" value="">
            <input type="hidden" name="parent" value="">
            <input type="text" name="content" class="form-control" placeholder="Add reply...">
            <input type="submit" class="btn btn-primary btn-xs" value="Add Reply">
        </form>
    <br>
@endif

Ask me if you need further detail
