vue触发rules规则显示提示信息 vue的rules

1、在代码中，添加属性：:rule

< Form ref = "loginForm" :model = "form" :rules = "rules" @ keydown.enter.native = "handleSubmit" class = "form-con" > < FormItem prop = "phone" > < Input v-model = "form.phone" prefix = "md-person" placeholder = "请输入您的手机号" size = "large" class = "login-form-input" :maxlength = "11" ></ Input > </ FormItem > < FormItem prop = "password" > < Input type = "password" v-model = "form.password" prefix = "md-lock" placeholder = "请输入您的密码" size = "large" class = "login-form-input" :maxlength = "100" ></ Input > </ FormItem > < FormItem prop = "code" > < Input v-model = "form.code" placeholder = "请输入验证码" prefix = "ios-barcode" size = "large" class = "login-form-input" :maxlength = "4" ></ Input > < img @ click = "refLoginImg" :src = "loginImgSrc" class = "login-img" /> </ FormItem > < FormItem > < Button @ click = "handleSubmit" :loading = "submitLoading" type = "info" long size = "large" class = "login-btn" icon = "md-log-in" > < span v-if = "!submitLoading" >立即登录</ span > < span v-else>正在登录，请稍候...</ span > </ Button > </ FormItem > </ Form >

2.新建一个文件（validate.js）定义验证规则

/** 这个文件只允许放表单验证方法 **/ //验证手机号 export function isPhone(rule, value, callback) { if (!value) { return callback( new Error( '输入不可以为空' )); } var pattern = /^1[34578]\d{9}$/ if (pattern.test(value)){ return callback() } return callback( new Error( '输入的手机号错误' )) }

3、在页面(xx.vue)中引入验证规则定义的文件，并在export default中定义rule规则，使用语法：{validator:验证方法,trigger:验证触发} validator

?

rules: { phone: [ { required: true , message: '手机号不能为空' , trigger: 'blur' }, { type: 'string' , min: 11, message: '手机号不允许小于11位' , trigger: 'blur' }, { validator: isPhone, trigger: 'blur' }, ], password: [ { required: true , message: '密码不能为空' , trigger: 'blur' }, { type: 'string' , min: 6, message: '密码不允许小于6位' , trigger: 'blur' }, ], code: [ { required: true , message: '验证码不能为空' , trigger: 'blur' }, { type: 'string' , min: 4, message: '验证码必须是4位' , trigger: 'blur' }, ], },

以下是validator.js文件的部分验证方法

?

/* 是否是公司邮箱*/ export function isWscnEmail(str) { const reg = /^[a-z0-9](?:[-_.+]?[a-z0-9]+)*@wallstreetcn\.com$/i; return reg.test(str.trim()); } /* 合法uri*/ export function validateURL(textval) { const urlregex = /^(https?|ftp):\/\/([a-zA-Z0-9.-]+(:[a-zA-Z0-9.&%$-]+)*@)*((25[0-5]|2[0-4][0-9]|1[0-9]{2}|[1-9][0-9]?)(\.(25[0-5]|2[0-4][0-9]|1[0-9]{2}|[1-9]?[0-9])){3}|([a-zA-Z0-9-]+\.)*[a-zA-Z0-9-]+\.(com|edu|gov|int|mil|net|org|biz|arpa|info|name|pro|aero|coop|museum|[a-zA-Z]{2}))(:[0-9]+)*(\/($|[a-zA-Z0-9.,?
