Bind classes to Global Scope in ES6

由 余生长醉 提交于 2021-01-06 18:50:29
问题 i'm trying to recreate jQuery validator in ES6 without using any jQuery, and i've kinda hit a roadblock in trying to recreate it's functionality for adding validation methods by using the Global scope , that is if you call Validator.addMethod anywhere, it'll run the associated function in the Validator and add a method to the Validator .

SpringBoot配置中@ConfigurationProperties和@Value的区别

由 隐身守侯 提交于 2021-01-06 06:46:59
基本特征 @ConfigurationProperties 与@Bean结合为属性赋值 与@PropertySource（只能用于properties文件）结合读取指定文件 与@Validation结合，支持JSR303进行配置文件值的校验，如@NotNull@Email等 @Value 为单个属性赋值 支持属性上的SpEL表达式 两者比较 @ConfigurationProperties @Value 功能 批量注入配置文件中的属性 一个个指定 松散绑定 支持 不支持 SpEL 不支持 支持 JSR303数据校验 支持 不支持 复杂类型封装 支持 不支持 我们用简单的例子来说明一下。 假设在application.properties文件中这样写道： 1 student.name= zhangsan 2 student.age= 25 3 student.class= mba 4 student.squad-leader= false 5 student.mail= zhangsan@gmail.com 6 7 student.maps.k1= aaa 8 student.maps.k2= bbb 9 student.maps.k3= ccc 10 11 student.lists= a,b,c 12 13 student.score.english= 95 14 student

How can this be a JSON Schema

由 浪尽此生 提交于 2021-01-05 12:57:24
问题 I'm trying to validate that a JSON Schema is actually a JSON Schema, and not an instance, as I have read, resource for that is validate against meta-schema e.g: Core validation meta-schema (http://json-schema.org/draft/2019-09/schema) Older versions meta-schema (https://json-schema.org/draft-04/schema) I have tried with different validation libraries, json-schema-validator for Java, and jsonschema for Python to have more assurance, but I keep on obtaining the funny assertion that this is a

Can anyone help the pattern ^[1-9]\d{0,2}(.\d{3})*(,\d+)?$ did not work for me, based from the similar thread here 回答1: You should try this expression: ^\d{1,3}|\d(([ ,]?\d{3})*([.,]\d{2}+)?$) With this

Dynamic value for max length in a regex

由 廉价感情. 提交于 2021-01-01 02:27:53
问题 i need to validate differents input value lengths. Inputs value can have a max length of 6 / 15 / 25 characters. Now i was asking to my self if it's a good practice use only one dynamic regex to validate differents max lengths, instead of copy paste the same regex. During my research i found that i've to use the the const regex = new RegExp() the problem is that i tried const lengthValidation = () => { const maxLength = 4; const inputValue = 'ciao'; const regex = new RegExp(`/^.{6,${maxLength
