前言：在日常开发当中经常用到一些正则表达式， 比如 电话号码、邮箱、IP和 数字等校验，每次都要去查阅下才知道怎么书写，特封装一个，方便后续查阅，本文会持续更新，也非常欢迎小伙伴们来评论区补充~
- 封装一个公共 js文件，名命为
validate.js如下：
export default {
telphone: (rule, value, callback) => {
if (value === '') {
callback()
return
}
const pass = /^(0[0-9]{2,3}-)?([2-9][0-9]{6,7})+(-[0-9]{1,4})?$/g.test(
value
)
if (!pass) {
callback(new Error(rule.message || '正确格式: 区号-电话号码 或 电话号码'))
}
callback()
},
phone: (rule, value, callback) => {
if (value === '') {
callback()
return
}
const pass = /^(\\+86)?0?[1][34578][0-9]{9}$/g.test(value)
if (!pass) {
callback(new Error(rule.message || '请输入正确的电话号码'))
}
callback()
},
email: (rule, value, callback) => {
if (value === '') {
callback()
return
}
const pass = /^[a-zA-Z0-9_.-]+@([a-zA-Z0-9-]+\.)+[a-zA-Z0-9]{2,4}$/g.test(
value
)
if (!pass) {
callback(new Error(rule.message || '请输入正确的邮箱'))
}
callback()
},
money: (rule, value, callback) => {
if (value === '') {
callback()
return
}
const pass = /^\-?(?!0+)?:.0+)?$)(?:[1-9]\d*|0)(?:.\d{1,2})?$/.test(value))
if (isNaN(value)) {
return callback(new Error('必须为数字'));
}
if (String(value).split('.').length > 0) {
if (String(value).split('.')[0].length > 9) {
return callback(new Error('整数部分不能大于9位'));
}
if (value !== 0) {
if (!pass || !value) {
return callback(new Error('钱数精确两位小数'));
}
}
}
callback();
},
postcode: (rule, value, callback) => {
if (value === '') {
callback()
return
}
const pass = /^\d{6}$/g.test(value)
if (!pass) {
callback(new Error(rule.message || '必须是6位数字'))
}
callback()
},
notValidInputText: (rule, value, callback) => {
if (value === '') {
callback()
return
}
const pass = /^[^'/\\"()@$%^*<>&?]*$/g.test(value)
if (!pass) {
callback(new Error(rule.message || '不能包含特殊字符^\'\\"()@$%^*<>&?*'))
}
callback()
},
isNumber: (rule, value, callback) => {
if (value === '') {
callback()
return
}
const pass = /^[0-9]*$/g.test(value)
if (!pass) {
callback(new Error(rule.message || '只能为数字'))
}
callback()
},
ip: (rule, value, callback) => {
if (value === '') {
callback()
return
}
const pass = /^(\d{1,2}|1\d\d|2[0-4]\d|25[0-5])\.(\d{1,2}|1\d\d|2[0-4]\d|25[0-5])\.(\d{1,2}|1\d\d|2[0-4]\d|25[0-5])\.(\d{1,2}|1\d\d|2[0-4]\d|25[0-5])$/g.test(
value
)
if (!pass) {
callback(new Error(rule.message || '请输入正确的ip地址'))
}
callback()
},
letterOrNumber: (rule, value, callback) => {
if (value === '') {
callback()
return
}
const pass = /^[0-9a-zA-Z]+$/g.test(value)
if (!pass) {
callback(new Error(rule.message || '只能是数字和字母'))
}
callback()
},
id: (rule, value, callback) => {
if (value === '') {
callback()
return
}
const pass = /^[a-zA-Z0-9-]{3,20}$/g.test(value)
if (!pass) {
callback(new Error(rule.message || '只能为 3-20 位字符串'))
}
callback()
},
number: (rule, value, callback) => {
if (value === '') {
callback()
return
}
const pass = /^[0-9]{1,10}$/g.test(value)
if (!pass) {
callback(new Error(rule.message || '必须是数字'))
}
callback()
},
positiveNumber: (rule, value, callback) => {
if (value === '') {
callback()
return
}
const pass = /^[0-9]\d*$/g.test(value)
if (!pass) {
callback(new Error(rule.message || '必须是正整数'))
}
callback()
},
posiNactiveNumber: (rule, value, callback) => {
if (value === '') {
callback()
return
}
const pass = /^[+-]?\d+(\.\d+)?$/g.test(value)
if (!pass) {
callback(new Error(rule.message || '可输入正数负数和小数'))
}
callback()
}
}
- 在组件中引用该 js 文件即可
import validate from '@/util/validate.js'
- （以element-ui为例）在需要校验的输入框位置，直接调用
validate.***即可
rules: {
validtime: [
{
required: true,
message: '请输入校验信息',
trigger: ['change', 'blur']
},
{
validator: validate.notValidInputText,
message: '',
trigger: ['change', 'blur']
}
]
}
- demo示例
<template>
<div>
<el-form ref="searchform" :model="form" :rules="rules" label-width="150px">
<el-form-item label="正则表达式校验" prop="validtime">
<el-input
type="text"
v-model="form.validtime"
placeholder="请输入内容"
></el-input>
</el-form-item>
</el-form>
</div>
</template>
<script>
import validate from '@/util/validate.js'
export default {
data() {
return {
form: {
validtime: ''
},
rules: {
validtime: [
{
required: true,
message: '请输入校验信息',
trigger: ['change', 'blur']
},
{
validator: validate.notValidInputText,
message: '',
trigger: ['change', 'blur']
}
]
}
}
}
}
</script>
