vue3项目中常用表单验证挂载到vue实例

// 表单验证
export default {
  install: function(Vue) {
    // 空验证
    Vue.config.globalProperties.check_null = function(txt) {
      return txt == '' ? true : /^[ ]+$/g.test(txt)
    }
    // 手机验证
    Vue.config.globalProperties.check_phone = function(txt) {
      return /^(1d{10})$/g.test(txt)
    }
    // 检测固话号码
    Vue.config.globalProperties.check_tele = function(txt) {
      return /^((0d{2,3}-d{7,8}))$/g.test(txt)
    }
    // 检测手机和固话
    Vue.config.globalProperties.check_telephone = function(txt) {
      return /^((0d{2,3}-d{7,8})|(1d{10}))$/g.test(txt)
    }
    // 邮箱验证
    Vue.config.globalProperties.check_email = function(txt) {

    //   return /^(https?://)?([da-z.-]+).([a-z.]{2,6})([/w .-]*)*/?$/g.test(txt)

    // 检测ip地址
    Vue.config.globalProperties.check_ip = function(txt) {
      return /^(d{1,2}|1dd|2[0-4]d|25[0-5]).(d{1,2}|1dd|2[0-4]d|25[0-5]).(d{1,2}|1dd|2[0-4]d|25[0-5]).(d{1,2}|1dd|2[0-4]d|25[0-5])$/g.test(
        txt
      )

    // 金钱验证（两位小数）
    Vue.config.globalProperties.check_money = function(txt) {

在main.js中引用即可

import formcheck from './utils/formcheck'
const app = createApp(App)
app.config.globalProperties.http = () => {
  console.log('i am http')
}
app
  .use(formcheck)
  .mount('#app')

组件内使用

const { proxy} = getCurrentInstance();
console.log(proxy.check_null("aaaaaaa"));//true
