前端实现类似 Laravel 风格的表单验证库

let validator = new Validation(this.registerForm, {
    telephone: "required|telephone",
    captcha: "required|length:5",
}, {
    telephone: {
        required: "手机号不能为空",
        telephone: "手机号格式不正确",
    },
    captcha: "验证码不正确"
})
try {
    validator.validate()
} catch(e) {
    uni.showToast({
        icon: 'error',
        title: e.message
    })
}

npm install @church1117/form-validation

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: "不正确的手机格式",
        age: {
            numeric: "年龄不是一个有效的数值",
            between: "年龄必须在18-60岁之间"
        },
        password: {
            required: "密码不能为空",
            min: "密码长度不能小于6位",
            regex: "密码只能由数字、大小写字母构成",
        },
        captcha: "验证码不正确",
        idcard: {
            required: "身份证不能为空",
            idcard: "身份证格式不正确",
        },
        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);

Validation.register('testRule', function(value, field) {
    if (typeof value != 'undefined' && value != 'test') {
        throw new Error(`${field} must equal test`)
    }
});

npm test
