前言:在我们做vue项目,日常开发的时候,肯定会经常遇到正则表达式,例如手机号,邮箱,密码和数字,每次验证都需要去查询,浪费时间不说,也造成代码冗余,我也遇到过,那我就自己封装一个吧,方便大家使用查询。
上代码:
1. 个人封装一个公共的 js文件,名命为 rule.js, 如下:
export default {
// 手机号验证
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}$/g.test(
value
)
if (!pass) {
callback(new Error(rule.message || '请输入正确的邮箱'))
}
callback()
},
postcode: (rule, value, callback) => {
if (value === '') {
callback()
return
}
const pass = /^\d{6}$/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()
},
letterOrNumberorUl: (rule, value, callback) => {
if (value === '') {
callback()
return
}
const pass = /^\w+$/.test(value)
if (!pass) {
callback(new Error(rule.message || '只能是数字和字母和_'))
}
callback()
},
id: (rule, value, callback) => {
if (value === '') {
callback()
return
}
const pass = /^[a-zA-Z0-9-]{3,20}$/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()
}
}
2.在组件中引用:
import rule from '@/util/rule.js'
3. 在需要校验的输入框位置,直接调用 rule.rule即可
rules: {
validate: [
{
required: true,
message: '请输入校验信息',
trigger: ['change', 'blur']
},
{
validator: rule.notValidInputText,
message: '',
trigger: ['change', 'blur']
}
]
}
