使用类别标题和内容过滤字段(php Laravel jquery)

public function filterContent(Request $request)
{
    $category = $request->input('category');
    $keyword = $request->input('keyword');

    $query = Content::query();

    if ($category) {
        $query->where('category', $category);
    }

    if ($keyword) {
        $query->where('title', 'LIKE', '%' . $keyword . '%')
              ->orWhere('description', 'LIKE', '%' . $keyword . '%');
    }

    $filteredContents = $query->get();

    return response()->json($filteredContents);
}

<select id="categoryFilter">
    <option value="">所有类别</option>
    <!-- 动态生成选项 -->
</select>
<input type="text" id="keywordFilter" placeholder="搜索...">
<ul id="contentList">
    <!-- 内容列表 -->
</ul>

<script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>
<script>
$(document).ready(function() {
    $('#categoryFilter, #keywordFilter').on('change keyup', function() {
        var category = $('#categoryFilter').val();
        var keyword = $('#keywordFilter').val();

        $.ajax({
            url: '/filter-content',
            type: 'GET',
            data: { category: category, keyword: keyword },
            success: function(response) {
                $('#contentList').empty();
                $.each(response, function(index, content) {
                    $('#contentList').append('<li>' + content.title + '</li>');
                });
