Question

我第一次尝试在Laravel中使用数据表，并且遇到了Yajra lib。我正在使用Laravel Framework 5.8.34，mySQL数据库。我正在关注this教程。我无法使其显示搜索，分页等信息，例如其示例：

矿井出来像：

使用PHP时，我知道这是一个JS问题，但这是我的刀片：

@section('content')

这是我的控制器：

public function index(Request $request)
{
    if(request()->ajax())
    {
        if(!empty($request->filter_type_of_leave))
        {
            $data = DB::table('leaves')
                ->select('paynumber', 'type_of_leave', 'applied_by', 'days_taken')
                ->where('type_of_leave', $request->filter_type_of_leave)
                ->where('applied_by', $request->filter_applied_by)
                ->get();
        }
        else
        {
            $data = DB::table('leaves')
                ->select('paynumber', 'type_of_leave', 'applied_by', 'days_taken')
                ->get();
            //dd(datatables()->of($data)->make(true));
        }

        return datatables()->of($data)->make(true);

    }

    $leaveslist = DB::table('leaves')
        ->select('paynumber', 'type_of_leave', 'days_taken','date_from','date_to','applied_by')
        ->orderBy('created_at', 'DESC')
        ->get();
//dd($leaveslist);
    return view('dashboard', compact('leaveslist'));
}

Firefox控制台出现了一些错误，但我认为它们不会影响任何事情：

任何帮助将不胜感激。我尝试过this，this和this，但没有运气，perharps我错过了一些东西。

更新： 1.我删除了foreach语句。 2.确保jQuery已加载，在数据表之前加载了1st，因为如果它们在任何其他JS之后加载，则会出现错误。 3.按照建议设置一个部分。

现在正在加载数据，但将其压缩在一起，必须是Bootstrap ??，现在正在处理该数据

Answer 1

问题是JS和CSS冲突。
