Laravel5.8使用LayUI实现动态删除

Route::delete('pic/destroy/{id}', 'PicController@destroy'); //图片单个删除控制器

<table class="layui-table" id="table">
    <thead>
    <tr>
        <th></th>
        <th>ID</th>
        <th>标题</th>
        <th>排序</th>
        <th>缩略图</th>
        <th>操作</th>
    </tr>
    </thead>
    <tbody>
    @foreach($data as $value)
        <tr>
            <td>
                <div class="layui-form">
