這篇文章主要介紹了vue3自定義確認(rèn)密碼匹配驗(yàn)證規(guī)則的操作代碼,本文通過(guò)實(shí)例代碼給大家介紹的非常詳細(xì),對(duì)大家的學(xué)習(xí)或工作具有一定的參考借鑒價(jià)值,需要的朋友參考下吧

vue3自定義確認(rèn)密碼匹配驗(yàn)證規(guī)則

// 自定義確認(rèn)密碼匹配驗(yàn)證規(guī)則
const matchPassword = (rules:any, value:any, callback:any) => {
	if (value != addData.payPwd) {
		callback(new Error('兩次密碼輸入不一致！'))
	} else {
		callback()
	}
}
const rules = reactive({
  payPwd: [
    { required: true, message: "請(qǐng)輸入支付密碼", trigger: "blur" },
    {
      pattern: /^\d+$/,
      message: "只能輸入6位數(shù)字",
      trigger: "blur",
    },
  ],
  repeatedPwd: [

      trigger: "blur",
    },
    {validator: matchPassword, trigger: 'blur'}
  ],
});

擴(kuò)展：

vue中表單使用自定義驗(yàn)證規(guī)則

vue中表單使用自定義驗(yàn)證規(guī)則（以2次輸入密碼為例）

先安裝elementUI

yarn add element-ui

mian.js中引入elementUI

import ElementUI from 'element-ui';
import 'element-ui/lib/theme-chalk/index.css';
Vue.use(ElementUI);

創(chuàng)建表單

<el-form ref="form" :model="form" :rules="rules">
     <el-form-item label="新密碼" prop="newPwd">
          <el-input type="password" v-model="form.newPwd"></el-input>
     </el-form-item>
     <el-form-item label="確認(rèn)密碼" prop="confirmPwd">
          <el-input type="password" v-model="form.confirmPwd"></el-input>
     </el-form-item>
     <el-form-item>
          <el-button @click="confirmBtn">確認(rèn)</el-button>
          <el-button @click="resetBtn">重置</el-button>
     </el-form-item>
</el-form>

定義數(shù)據(jù)及驗(yàn)證規(guī)則

data() {
     var checkPwd = (rule, value, callback) => {
          if (value === this.form.newPwd) {
                callback();
            } else {
                callback(new Error('兩次輸入密碼不一致!'));
            }
        }
     return {
          form: {
                newPwd: '',
                confirmPwd: ''
            },
          rules: {
                newPwd: [
                    { required: true, message: '請(qǐng)輸入密碼', trigger: 'blur' },
                    { min: 6, max: 12, message: '長(zhǎng)度在 6 到 12 個(gè)字符', trigger: 'blur' }
                ],
                confirmPwd: [
                    { required: true, message: '請(qǐng)?jiān)俅屋斎朊艽a', trigger: 'blur' },
                    { min: 6, max: 12, message: '長(zhǎng)度在 6 到 12 個(gè)字符', trigger: 'blur' },
                    { validator: checkPwd, trigger: 'blur' }
                ]
            }
        }
    },

綁定操作按鈕

methods: {
     //確認(rèn)按鈕
     confirmBtn() {
          this.$refs.form.validate(res => {
                if (res) {
                    console.log('修改成功');
                } else {
                    console.log('修改失敗');
                    return false;
                }
            });
        },
     //重置按鈕
     resetBtn() {
          this.$refs.form.resetFields();
        }
    }
