javascript - 根据JS中html标签的类和id(增量)隐藏和显示div

Question

目前我有多个使用MDB前端框架的选择选项

我正在使用不同的类、id 和名称加载它

这是工作代码

 @if(count($manage_access_list))
                    @foreach($manage_access_list as $field)
                        <div class="row">
                            <div class="col-md-2">
                                {{$field->access_desc}}
                            </div>
                            <div class="col-md-4">
                                <select class="mdb-select accessSelect{{$field->id}}" name="accessSelect{{$field->id}}" id="accessSelect{{$field->id}}" style="width: 170px!important;">
                                    <option value="" disabled selected>Select Access Right</option>
                                    <option value="ALL">All Access</option>
                                    <option value="NO">No Access</option>
                                    <option value="CONFIG">Config Access</option>
                                </select>
                            </div>

                                <div class="col-md-2 access-right{{$field->id}}" style="display:none;">
                                    <div class="custom-control custom-checkbox">
                                    <input type="checkbox" class="custom-control-input add{{$field->id}}" name="add{{$field->id}}" id="add{{$field->id}}">
                                        <label class="custom-control-label" for="add{{$field->id}}">Add</label>
                                    </div>
                                </div>
                                <div class="col-md-2 access-right{{$field->id}}" style="display:none;">
                                    <div class="custom-control custom-checkbox">
                                    <input type="checkbox" class="custom-control-input edit{{$field->id}}" name="edit{{$field->id}}" id="edit{{$field->id}}">
                                        <label class="custom-control-label" for="edit{{$field->id}}">Edit</label>
                                    </div>
                                </div>
                                <div class="col-md-2 access-right{{$field->id}}" style="display:none;">
                                    <div class="custom-control custom-checkbox">
                                    <input type="checkbox" class="custom-control-input remove{{$field->id}}" name="remove{{$field->id}}" id="remove{{$field->id}}">
                                        <label class="custom-control-label" for="remove{{$field->id}}">Remove</label>
                                    </div>
                                </div>

                        </div>
                    @endforeach
                @endif

这是我的 JS 代码

<script>
$("#accessSelect1").on('change', function() {
    if(this.value == "ALL"){
       $(".access-right1").hide();
    }
    else if (this.value == "NO"){
        $(".access-right1").hide();
    }
    else if(this.value == "CONFIG"){
        $(".access-right1").show();
    }
  });

  </script>

输出:

如您所见，select option > accessSelect1 的 id 是硬编码的

我想做的是显示和隐藏每行的特定添加、编辑、删除。使用select option accessSelect

的id

到目前为止，div 的显示和隐藏仅适用于 accessSelect1

Answer 1

// [id^=accessSelect] will select all IDs starting with"accessSelect"
$("[id^=accessSelect]").on('change', function() { 
    // from the current select get the parent .row element
    // from there chose the child containing a class "access-right"
    var $accessRights = $(this).closest('.row').children('[class*=access-right]');
    if($(this).val() == "CONFIG") {
        $accessRights.show();
    } else {
       // if it's not "CONFIG" you want to hide them allways
       $accessRights.hide();
    }
});
