Javascript计数对象'；有点符号的s键

正在尝试计算javascript对象中的数组。此响应来自laravel验证器

         "Please select a room type"

      "room_number.23":[  
         "Room number cannot be empty"
      ],
      "room_number.24":[  
         "Room number cannot be empty"
      ],
      "room_number.25":[  
         "Room number cannot be empty"

      "room_number.26":[  
         "Room number cannot be empty"
      ],
      "room_number.27":[  
         "Room number cannot be empty"
      ],
      "room_number.28":[  
         "Room number cannot be empty"
      ]
   }
}

在上面的js对象中，错误对象包含

“floor.0”：[“请选择一个楼层]，“floor.1”：[“请选择一个楼层]，“floor.2”：[“请选择一个楼层”]

等等

我想数一数有多少

floor.

阵列存在

注: 我正在访问如下所示的单个值

$("#floor_error_1").text(data.responseJSON.errors["floor.0"]);
$("#floor_error_2").text(data.responseJSON.errors["floor.1"]);

如何计算？然后循环并打印错误？

您可以使用来获取数组中

错误
的
键。然后
filter
仅对项目“floor”进行筛选并获取其长度

您还可以使用regex代替
startsWith

Object.keys(data.errors).filter(x => x.startsWith('floor')).length

要打印错误，您可以尝试：

let errorKeys = Object.keys(data.errors).filter(x => x.startsWith('floor'));

let count = errorKeys.length;

let floorErrors = errorKeys.map(key => ({
    key: key,
    errors: data.errors[key]
}));

}
让errorKeys=Object.keys（data.errors）.filter（x=>x.startsWith（'floor'））；
让计数=errorKeys.length；
让floorErrors=errorKeys.map（key=>({
钥匙：钥匙，
错误：数据。错误[键]
}));
控制台日志（错误键、计数、楼层错误）
console.log（）


var data={}；
data.responseJSON='{“消息”：“给定的数据无效”，“错误”：“{”roomtype_id:“[请选择房间类型]，“价格”：[“价格不能为空”]，“便利设施”：[“至少选择一个便利设施”]，“floor.0:[“请选择一层”]，“floor.1:[“请选择一层”]，“floor.2:[“请选择一层”]，“floor.3:[“请选择一层”]，“floor.4”：[“请选择楼层”]，“房间号.0”：[“房间号不能为空”]，“房间号.1”：[“房间号不能为空”]，“房间号.2”：[“房间号不能为空”]，“房间号.3”：[“房间号不能为空”]，“房间号.4”：[“房间号不能为空”]，“房间号.5”：[“房间号不能为空”]，“房间号.6”：[“房间号不能为空”]，“房间号.7:[“房间号不能为空”]，“房间号.8:[“房间号不能为空”]，“房间号.9:[“房间号不能为空”]，“房间号.10:[“房间号不能为空”]，“房间号.11:[“房间号不能为空”]，“房间号.12:[“房间号不能为空”]，“房间号.13:”房间号不能为空“]，“房间号.14:[“房间号不能为空”]，“房间号.15:[“房间号不能为空”]，“房间号.16:[“房间号不能为空”]，“房间号.17:[“房间号不能为空”]，“房间号.18:[“房间号不能为空”]，“房间号.19:[“房间号不能为空”]，“房间号.20:”房间号不能为空“]，“房间号.21:[“房间号不能为空”]，“房间号.22:[“房间号不能为空”]，“房间号.23:[“房间号不能为空”]，“房间号.24:[“房间号不能为空”]，“房间号.25:[“房间号不能为空”]，“房间号.26:[“房间号不能为空”]，“房间号.27:”房间号不能为空“]，“房间号.28”：[“房间号不能为空”]}}；
data.responseJSON=JSON.parse（data.responseJSON）；
//开始在这里循环
var计数器=0；
for（变量输入data.responseJSON.errors）{
//检查kkey上是否有“地板”
如果（键索引（“地板”）！=-1）{
//该键具有文本层。
计数器++；
console.log（data.responseJSON.errors[key][0]）；
} 
}
console.log（“总错误为”+计数器）；
只是删除
data.responseJSON=JSON.parse（data.responseJSON）；
这行代码都工作正常。谢谢是的，这段代码只是用来解析
