Passing data attribute value into blade route

I'm building a blog to learn Laravel (5.4.13). In my posts show view I'm looping through all the corresponding post comments. Beside each comment is an edit button and a delete button. For comment editing, I'm attempting to use a modal instead of redirecting to the typical edit view. Currently I'm storing the specific comment data within two data-attributes, and then retrieving those values using jQuery. Then I'm using jQuery again to pass the data into the modal. This is working fine except I'm not sure how to pass the $comment->id into the form route. Any help is much appreciated.

@extends('main')
@section('title', 'View Post')
@section('content')
    <div class="row">
        <div class="col-md-8">
            <h1><a href=""></h1></a>
            <small>Published: <i class="fa fa-clock-o"></i> </small>
            <hr class="light-hr">
            <p class="lead"></p>  
            <hr>

            <div class="tags">
                @foreach($post->tags as $tag)
                    <span class="label">
                        <a href="" class="btn btn-sm btn-primary"></a>
                    </span>
                @endforeach
            </div>
            <br>
            <br>
            
            <h4>Related Posts <i class="fa fa-level-down"></i></h4>
            @foreach($post->comments as $comment)
                <?php $avatars = array('monsterid', 'identicon', 'wavatar', 'retro'); ?>
                <?php $randAvatars = urlencode($avatars[array_rand($avatars)]); ?>
