使用记录

我使用的 “vee-validate”: “^3.0.3”,
和网上2.x的使用教程不太一样。
VeeValidate 文档地址
官方的一个demo

首先安装 “vee-validate”,

在项目中创建个validate.js文件

开始配置vee-validate
在validate.js文件中

自定义消息

ocalize(‘zh_CN’, {
name: ‘zh_CN’,
names: {
nationalID: ‘身份证号’,
patientname: ‘就诊人姓名’, // 这个是中文提示，如不设置的话就会直接使用name值
phoneNo: ‘联系方式’,
cardType: ‘就诊卡号’
},
messages: {
// your messages.
_default: (field) => ${field}无效,
after: (field, [target]) => ${field}必须在${target}之后,
alpha_dash: (field) => ${field}能够包含字母数字字符、破折号和下划线,
alpha_num: (field) => ${field}只能包含字母数字字符,
alpha_spaces: (field) => ${field}只能包含字母字符和空格,
alpha: (field) => ${field}只能包含字母字符,
before: (field, [target]) => ${field}必须在${target}之前,
between: (field, [min, max]) => ${field}必须在${min}与${max}之间,
confirmed: (field, [confirmedField]) =>
${field}不能和${confirmedField}匹配,
credit_card: (field) => ${field}格式错误,
date_between: (field, [min, max]) => ${field}必须在${min}和${max}之间,
date_format: (field, [format]) => ${field}必须符合${format}格式,
decimal: (field, [decimals = ‘*’] = []) =>
${field}必须是数字，且能够保留${ decimals === '*' ? '' : decimals}位小数,
digits: (field, [length]) =>
${field}必须是数字，且精确到${length}位数,
dimensions: (field, [width, height]) =>
${field}必须在${width}像素与${height}像素之间,
email: (field) => ${field}不是一个有效的邮箱,
ext: (field) => ${field}不是一个有效的文件,
image: (field) => ${field}不是一张有效的图片,
included: (field) => ${field}不是一个有效值,
integer: (field) => ${field}必须是整数,
ip: (field) => ${field}不是一个有效的地址,
length: (field, [length, max]) => {
if (max) {
return ${field}长度必须在${length}到${max}之间
}
return ${field}长度必须为${length}
},
max: (field, [length]) => ${field}不能超过${length}个字符,
max_value: (field, [max]) => ${field}必须小于或等于${max},
mimes: (field) => ${field}不是一个有效的文件类型,
min: (field, [length]) => ${field}必须至少有${length}个字符,
min_value: (field, [min]) => ${field}必须大于或等于${min},
excluded: (field) => ${field}不是一个有效值,
numeric: (field) => ${field}只能包含数字字符,
regex: (field) => ${field}格式无效,
required: (field) => 请输入${field},
url: (field) => field + ‘不是一个有效的url’
}
})

全部代码，复制到validate.js

import Vue from 'vue'
import {ValidationProvider, extend, localize} from 'vee-validate'
import {required, email} from 'vee-validate/dist/rules' // 验证规则导入
// import CN from 'vee-validate/dist/locale/zh_CN.json' // 加载语言包


extend('required', required)

// 手机号码验证
extend('mobile', {
  message: () => `请输入正确的手机号码`,
  validate: value => value.length === 11 && /^(((13[0-9]{1})|(14[57]{1})|(15[012356789]{1})|(17[03678]{1})|(18[0-9]{1})|(19[89]{1})|(16[6]{1}))+\d{8})$/.test(value)
})
// 设置
Vue.component('ValidationProvider', ValidationProvider)

定义的验证规则 一定要放在最后localize后面，不然会覆盖的
注意 要在main中引用

在页面中使用

<ValidationProvider rules="required" name="nationalID" v-slot="{ errors }">
        <van-field
          v-model="user.nationalID"
          type="number"
          label="身份证号"
          clearable
          placeholder="必填"
          maxlength="18"
          name="phoneNo"
          :error-message="errors[0]"
        />
      </ValidationProvider>

这里有个BUG

使用ValidationProvider包裹vant的van-field控件会造成van-field上方的灰色横线不见。

展示结果

提交验证

用ValidationObserver 扩起表单
然后提交



form 是定义的name。
还有一种写法官方demo
