validation-es6

使用ES6编写的一个类似laravel的js验证模块.

安装

$ npm install validation-es6

基本用法

import {
    Validator
} from './node_modules/validation-es6/validator.js';

let rules = {
  username: 'required|min:5',
  password: 'required|confirmed|min:6|max:16',
}

let data = {
  username: 'test',
  password: '123456',
}

let v = new Validator(data, rules);

if (v.fails()) {
    console.log(v.messages());
}

定义验证规则

• "|" 分隔的字符串形式

let rules = {
  username: 'required|min:5',
  password: 'required|confirmed|min:6|max:16',
  email: 'email'
}

• 数组形式

let rules = {
  username: ['required', 'min:5'],
  password: ['required', ['confirmed'], ['min:6'], ['max:16'],
  email: ['required', 'email']
}

其他

• 自定义错误消息、属性别名、验证函数

  在消息字符串用使用:attribute 作为属性名占位符。

  //错误消息
  let customMessages = {
      accepted: ":attribute 必须接受",
  };
  
  //属性别名
  let attribute = {
      "item": "条款"
  }
  
  //使用回调函数定义错误消息
  let replacers = {
      accepted: function (message, attribute, rule,parameters) {
          return message;
      }
  },
  
  let v = new Validator(data, rules, customMessages, attribute, replacers);
  
  //注册自定义验证函数
  v.register('upper', (attribute, value, parameters) => {
      return value.toUpperCase() == "NAME";
  }, ":attribute = :value 不对");
  
  if (v.fails()) {
      console.log(v.messages());
  }
