jQuery Ajax验证不返回错误

Question

我目前正在休假申请系统上。我有一个下拉字段，我要验证如果api返回false，则用户无法提交应用程序。

例如，如果没有年假（getLeaveAvailability return false）应返回错误消息。

表格：

 <div class="form-group">
                                        <label class="control-label col-md-3">Leave Type</label>
                                        <div class="col-md-9">

                                            <select type="text" id="leave_type" name="leave_type" required="required" class="leave_type form-control col-md-7 col-xs-12">
                                                <option value="">Select Leave Type</option>


                                                <option value="1">Annual Leave</option>
                                                <option value="2">Medical Leave</option>

                                            </select>

                                        </div>
                                    </div>

jQuery Ajax验证：

var validator = form.validate({
      debug: true,
      rules: {
        leave_type: {
          required: true,
          remote: {
            url: base_url + "/getLeaveAvailability",
            type: 'post',
            dataType: 'json',
            data: {
              leave_id: function() {
                return $('[name="leave_type"]').val();
              }
            }
          },
          // leave_type: true
        },
      },
      messages: {
        leave_type: {
          remote: "Leave not available!"
        }
      },

API响应：

 public function getLeaveAvailability(Request $request){

        return 'false';
    }

我认为您可能会通过以下代码获得帮助，

leave_type: {
      required: true,
      remote: {
        url: base_url + "/getLeaveAvailability",
        type: 'post',
        dataType: 'json',
        data: {
          leave_id: function() {
            return $('[name="leave_type"]').val();
          }
        },
        success: function(response) {
            if (response.responseText == "true") { //here you have to check the return response from server side
                //Write statement if success

            } else {  
                //Write statement if failed
            }
        }
    }
}
