Laravel 通过 ajax 进行数组验证：显示错误消息引发错误

Question

正在尝试通过 FormRequest 验证来验证 laravel 中的数组

<?php

namespace App\Http\Requests;

use Illuminate\Foundation\Http\FormRequest;

class VendorStoreRoom extends FormRequest
{
    /**
     * Determine if the user is authorized to make this request.
     *
     * @return bool
     */
    public function authorize()
    {
        return true;
    }

    /**
     * Get the validation rules that apply to the request.
     *
     * @return array
     */
    public function rules()
    {
        return [
            'roomtype_id' => 'required',
            'price' => 'required|digits_between:1,8',
            'amenities' => 'required',

            //'max_children' => 'required',
            'max_adult' => 'required',
            //'capacity' => 'required',
            'floor.*' => 'required',
            'room_count' => 'min:1|max:50',
            'room_number.*' => 'required',
            //'room_number' => 'required|max:5',
            'image' => 'required',
        ];
    }


    public function messages()
    {
        return [
            'roomtype_id.required'      => 'Please select a room type',

            'price.required'            => 'Price cannot be empty',
            'price.digits_between'      => 'Price cannot exceed 8 digits',

            'amenities.required'        => 'Atleast select one amenities',

            //'max_children.required'     => 'Vendor name cannot be empty',

            'max_adult.required'     => 'Maximum adult can not be empty',

            //'capacity.required'     => 'Vendor name cannot be empty',

            'floor.*.required'     => 'Please select a floor',

            'room_count.min'     => 'Room count cannot be empty',
            'room_count.max'     => 'Room count cannot exceed 50',

            'room_number.*.required'     => 'Room number cannot be empty',
            //'room_number.max'     => 'Room number cannot exceed 5 characters',

            'image.required'     => 'Atleast select one image',
            /*'image.*.mimes'     => 'Image Must be JPEG, JPG or PNG',
            'image.*.min'     => 'Image size must be more than 10 kb',
            'image.*.max'     => 'Image size cannot exceed 300 mb', */


        ];
    }
}

这是我得到的回复：

{"message":"The given data was invalid.","errors":{"roomtype_id":["Please select a room type"],"price":["Price cannot be empty"],"amenities":["Atleast select one amenities"],"image":["Atleast select one image"],"floor.0":["Please select a floor"],"room_number.0":["Room number cannot be empty"]}}

我在 jquery 中发现了这些错误，并按如下操作：

这很好用：$("#amenities_error").text(data.responseJSON.errors.amenities);

但不是这个：$("#floor_error").text(data.responseJSON.errors.floor.0); 我怎样才能做到这一点？

有什么我可以做的，比如 data.responseJSON.errors."floor.0" 或 data.responseJSON.errors.{floor.0}

Answer 1

floor.0 是导致此错误的关键字符串。但是，javascript 将 . 视为属性分隔符。因此，javascript 搜索具有属性 0 的对象 floor。
要解决此问题，您必须为此键使用数组语法。

$("#floor_error").text(data.responseJSON.errors["floor.0"]);
