介绍
Laravel 的表单验证很不便,想在前端也用这样的形式进行验证。
git 地址,欢送star
期待这个表单验证库有这样的性能。
let validator = new Validation(this.registerForm, { telephone: "required|telephone", captcha: "required|length:5",}, { telephone: { required: "手机号不能为空", telephone: "手机号格局不正确", }, captcha: "验证码不正确"})try { validator.validate()} catch(e) { uni.showToast({ icon: 'error', title: e.message })}
构造函数的第三个参数 messages 能够不要,默认是英文提醒。而且该参数反对不同粒度的错误信息,如果传对象,则如果对应的规定校验不通过,就应用对应的错误信息;如果传字符串,则不论什么规定未通过,都应用该错误信息。
内置一些规定,如果不够用,还能够本人扩大。
依据以上的需要,就有了这个库 @church1117/form-validation
。
装置
npm install @church1117/form-validation
应用
import Validation from "@church1117/form-validation"let data = { name: "church", mobile: "18565919379", age: 19, gender: '2', password: "123456", captcha: "12345", idcard: '42052919910727452X', email: "xxx@qq.com", test: "ttt", birthday: '1993/11/17', }let rules = { name: "required|between:6,255", mobile: "required|telephone", age: "numeric|between:8,60", gender: "numeric|range:" + gender.join(','), password: "required|min:6|password", captcha: "required|length:5", idcard: "required|idcard", email: "email", // test: "required|testRule" birthday: "datetime" }let messages = { name: { required: "名字不能为空", between: "名称长度必须在6~255之间", }, mobile: "不正确的手机格局", age: { numeric: "年龄不是一个无效的数值", between: "年龄必须在18-60岁之间" }, password: { required: "明码不能为空", min: "明码长度不能小于6位", regex: "明码只能由数字、大小写字母形成", }, captcha: "验证码不正确", idcard: { required: "身份证不能为空", idcard: "身份证格局不正确", }, test: { required: "测试字段不能为空", testRule: "该字段的值必须为test" } }let validation = new Validation(data, rules, messages);
- messages 能够定义不同粒度的错误信息,如果是字符串,那么该字段的所有验证规定都应用该错误信息。如果是对象,就只应用对应规定的错误信息。
内置规定
- required
- telephone
- min
- max
- between
- idcard
- range
- password
- numeric
- length
- datetime
自定义规定
匿名函数参数(value, field, ...params)
- value
- field
- ...params
Validation.register('testRule', function(value, field) { if (typeof value != 'undefined' && value != 'test') { throw new Error(`${field} must equal test`) }});
测试
npm test
