Warum wird meine Ausgabe in Blade PHP zweimal ausgegeben?

Question

Ich versuche, eine Live-Suchleiste zu implementieren. Die Live-Suche funktioniert, aber die Ausgabe wird zweimal gedruckt, was ärgerlich ist. Könnten Sie bitte einen Blick darauf werfen, wo das Problem liegt? Danke.

Dies ist mein Suchfunktionscode.

public function search(Request $request)
    {
        if ($request->ajax()) {
            
            $output = "";
            $projects = Project::where('title', 'LIKE', '%' . $request->search . '%')
                        ->where('module_code',$request->module_code)
                        ->get();
            $count = count($projects);
            // $projects = array_unique($projects);
            if ($projects) {
                foreach ($projects as $project) {
                    $output .= '<tr>' .
                        '<td>' . $project->team_number . '</td>' .
                        // '<td>' . $count . '</td>' .
                        '<td>' . $project->lab . '</td>' .
                        '<td>' . '<a href="/projects/' . $project->id . '" style="display:block;"><b>' . $project->title . '</b></a>' . '</td>' .
                        '<td>' . $project-> latest_state. '</td>' .
                        '<td>' . $project->team_member_1 . '</td>' .
                        '<td>' . $project->latest_team_member_1_state . '</td>' .
                        '<td>' . $project->team_member_1 . '</td>' .
                        '<td>' . $project->latest_team_member_1_state . '</td>' .
                        '<td>' . $project->team_member_1 . '</td>' .
                        '<td>' . $project->latest_team_member_1_state . '</td>' .
                        '<td>' . $project->ta . '</td>' .
                        '<td>' . $project->created_at . '</td>' .
                        '<td>' .
                        '<button class="btn-sm btn-info pull-left" onclick="location.href = \'/projects/' . $project->id . '\'">Project Details</button> ' .
                        '</td>' .
                        '</tr>';
                }
                return Response($output);
            }
        }
    }

Hier ist das Skript für die Live-Suche in PHP Blade:

<script type="text/javascript">
    const getQueryParams = (params, url)=>{
        let href = url;
        let regexp = new RegExp('[?&]' + params + '=([^&#]*)', 'i');
        let qString = regexp.exec(href);
        return qString ? qString[1] : null;
    }
    $('#search').on('keyup',function(){
        $value = $(this).val();
        //alert($value);
        $qString = getQueryParams('module', window.location.href);
        $queryString = 
        $.ajax({
            type : 'get',
            url  : '{{URL::to('search')}}',
            data : {'search':$value, 'module_code', $qString},
            success:function (data) {
                //console.log(data);
                //alert(data);
                $('tbody').html(data);
            }
        });
    })
</script>

Dies ist der Code für die Suchleiste in PHP Blade

<div class="col-sm-5">
                        <input type="text"  class="form-control" id="search" name="search" placeholder="Search..."/>
                    </div>

该死，我刚刚发现是什么原因导致了这个问题。这有点傻。原始代码在这里： https://onecompiler.com/posts/3xy39rm78/ php-blade-for-staff，该错误仍然存​​在。问题是，我添加了一个不必要的附加标签。输出被放置在有标签的地方，就像脚本一样：

$('#search').on('keyup',function(){
        $value = $(this).val();
        $qString = getQueryParams('module', window.location.href);
        $queryString = 
        $.ajax({
            type : 'get',
            url  : '{{URL::to('search')}}',
            data : {'search':$value, 'module_code': $qString},
            // data : {'search':$value},
            success:function (data) {
                //console.log(data);
                // alert(data);
                $('tbody').html(data);
            }
        });
    })

在代码的最后一点，它告诉 html 在标签处打印结果（我不确定这是否正确）。通过删除附加的tbody标签，问题就解决了。
