Javascript-如何将一个或两个选定的复选框放入数据库

Question

我需要选择一个或最多三个可以插入数据库的复选框，并且我有一个id jumlah，我需要输入并计算它（jumlah * harga）在id hasil上显示它。

这是我尝试并获得成功的jumlah * harga，但我想，只有在选中此复选框时，我才能计算出此值

 function sum(id) {
  var harga = document.getElementById('harga-' + id).value;
  var jumlah = document.getElementById('jumlah-' + id).value;
  var hasil = parseInt(harga) * parseInt(jumlah);
   if (!isNaN(hasil)) 
      {
         document.getElementById('total-' + id).value = hasil;
       }
}

这是我的表格

<form action="/po_store" method="post" enctype="multipart/form-data">
   @csrf
   <div class="container">
    <div class="row">
     <div class="col-md-6">
       <div class="form-group">
       <label>Tanggal PO</label>
       <input class="form-control" type="text" name="tanggal_po" id="datepicker">

       <div class="form-group">

         <select name="supplier_nama" class="form-control">
          <option value=""hidden>Pilih Supplier</option>
            @foreach ($supplier as $s)
                <option value="{{ $s->nama_supplier }}">{{ $s->nama_supplier }</option>
             @endforeach
         </select>

     <div class="col-md-6">

                @foreach ($apoteker as $a)
                   <option value="{{ $a->nama_apoteker }}">{{ $a->nama_apoteker }}</option>
                @endforeach
              </select>
          </div>
          <div class="form-group">
            <label>Keterangan</label>
            <input class="form-control" type="text" name="keterangan">

          </div>
        <table class="table table-bordered" id="tbl">

              <tr class="text-center">

               </tr>
             @foreach ($obat as $o)
              <tr>
             <td>
                <input id="check" type="checkbox" name="select" value="{{ $o->nama_obat }}" id="check" class="filled-in">

              </td>
             <td>
            <input id="total-{{ $o->id }}" type="text" class="form-control total-harga" name="total_harga" value="{{ old('total_harga') }}" onkeyup="sum({{ $o->id }})">
          </td>
          </tr>
           @endforeach
        </tbody>
       </table>
       </div>
      </div>
      <button type="submit" class="btn btn-success simpan simp-po" id="btnadd" onclick="selected()"><i class="fas fa-check"> Simpan</i></button>                
            </form>

这是我的po_store

$message = [
            'required' => '*:attribute harus diisi',
            'numeric' =>'*:attribute harus angka' ,
            'digits_between' => '*:attribute harus berisi 9 atau 13 angka'       
        ];

        $data = $request->validate([
            'tanggal_po' => ['required'],
            'no_po' => ['required'],
            'supplier_nama' => ['required'],
            'apoteker_nama' => ['required'],
            'jumlah'=>['required'],
            'harga_obat' =>['required'],
            'total_harga'=>['required'],
            'select'=>['required'],
        ],$message);

   if(PO::create($request->all())){
            $request->session()->flash('success', 'Data Berhasil Di Tambahkan');
        }else{
            $request->session()->flash('danger', 'Data Tidak Berhasil Di Tambahkan');
        }

我需要获取选中的复选框，并且其他数据如下图所示，因此每个复选框和数据都不会作为数组插入到记录中
