我有一个多选下拉列表和搜索按钮，点击搜索按钮，数据表中的所有数据都应该根据从下拉列表中选择的值进行过滤，但当我尝试过滤数据时，该表显示了我从下拉列表中选择的第一个值的记录。我不知道我做错了什么。
以下是我的html代码：

<div class="row">
    <div class="col-1">
        <div class="form-group">
            <select name="BusinessUnit[]" id="BusinessUnit" multiple class="form-control">
                @foreach($Business_unit_name as $Bu)
                <option value="{{ $Bu->BusinessUnit }}" style="font-size: 5px">{{ $Bu->BusinessUnit}}</option>
                @endforeach
            </select>           
        </div>
    </div>
    <div class="col-1">
        <div class="form-group">
            <select name="CurrOrg1" id="CurrOrg1" multiple class="form-control">
                @foreach($CurrOrg1_name as $org1)
                <option value="{{ $org1->CurrOrg1 }}">{{ $org1->CurrOrg1 }}</option>
                @endforeach
            </select>           
        </div>
    </div>
  <div class="col-1">
    <div class="form-group">
      <select name="CurrOrg2" id="CurrOrg2" multiple class="form-control">
        @foreach($CurrOrg2_name as $org2)
        <option value="{{ $org2->CurrOrg2 }}">{{ $org2->CurrOrg2 }}</option>
        @endforeach
      </select>       
    </div>
  </div>
  <div class="col-1">
    <div class="form-group">
      <select name="CurrOrg3" id="CurrOrg3" multiple class="form-control">
        @foreach($CurrOrg3_name as $org3)
        <option value="{{ $org3->CurrOrg3 }}">{{ $org3->CurrOrg3 }}</option>
        @endforeach
      </select>       
    </div>
  </div>
  <div class="col-1">
    <div class="form-group">

        <option value="{{ $org4->CurrOrg4 }}">{{ $org4->CurrOrg4 }}</option>
        @endforeach
      </select>       
    </div>
  </div>
  <div class="col-1">
    <div class="form-group">
      <select name="CurrOrg5" id="CurrOrg5" multiple class="form-control">
        @foreach($CurrOrg5_name as $org5)
        <option value="{{ $org5->CurrOrg5 }}">{{ $org5->CurrOrg5 }}</option>
        @endforeach
      </select>       
    </div>
  </div>
  <div class="col-1">
    <div class="form-group">

        @endforeach
      </select>

  </div>
    <div class="col-1">
        <div class="form-group">
            <select name="Role" id="Role" multiple class="form-control">
                @foreach($Role_name as $Role)
                <option value="{{ $Role->Role }}">{{ $Role->Role }}</option>
                @endforeach
            </select>           
        </div>
    </div>
  <div class="col-1">
    <div class="form-group">

        @endforeach
      </select>       
    </div>
  </div>

  <div class="col-1">
    <div class="form-group">
      <select name="Gender" id="Gender" multiple class="form-control">
        @foreach($Gender_name as $Gender)
        <option value="{{ $Gender->Gender }}">{{ $Gender->Gender }}</option>
        @endforeach
      </select>       
    </div>
  </div>
    <div class="col-1">
        <div class="form-group">
          <button class="btn btn-primary rounded" type="button" id="search" name="search" style="background-color: #CA0088;width: 70px">Apply</button>
        </div>
    </div>
    <div class="col-1">
        <div class="form-group">
          <button class="btn btn-primary rounded" type="button" id="reset" name="reset" style="background-color: #D5665F;width: 70px">Reset</button>
        </div>
    </div>

这是我的剧本：

$('#search').click(function(){
    var BusinessUnit = $('#BusinessUnit').val();
    var Role = $('#Role').val();
    var CurrOrg1 = $('#CurrOrg1').val();
    var CurrOrg2 = $('#CurrOrg2').val();
    var CurrOrg3 = $('#CurrOrg3').val();
    var CurrOrg4 = $('#CurrOrg4').val();
    var CurrOrg5 = $('#CurrOrg5').val();
    var Region = $('#Region').val();
    var ProfessionalClassification = $('#ProfessionalClassification').val();
    var Gender = $('#Gender').val();

    if(BusinessUnit != '' || CurrOrg1 != '' || CurrOrg2 != '' || Role != '' || Region != '' || Gender != '' || CurrOrg3 != '' || CurrOrg4 != '' || CurrOrg5 != '' || ProfessionalClassification != '') {
        $('#members_data').DataTable().destroy();
           fill_datatable(BusinessUnit,CurrOrg1,CurrOrg2,Role,Region,Gender,ProfessionalClassification,CurrOrg3,CurrOrg4,CurrOrg5);

    } else {
        alert('Select filter option');
    }
});

不确定我在这里做错了什么，是否有其他方法传递多个值？
