如何使用Vue和Element-UI进行数据校验与表单验证

npm install element-ui --save

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

<template>  <el-form ref="form" :model="form" :rules="rules" label-width="80px">    <el-form-item label="用户名" prop="username">      <el-input v-model="form.username"></el-input>    </el-form-item>    <el-form-item label="密码" prop="password">      <el-input type="password" v-model="form.password"></el-input>    </el-form-item>    <el-form-item>      <el-button type="primary" @click="submitForm">提交</el-button>      <el-button @click="resetForm">重置</el-button>    </el-form-item>  </el-form></template><script>export default {  data() {    return {      form: {        username: '',        password: ''      },      rules: {        username: [          { required: true, message: '请输入用户名', trigger: 'blur' },          { min: 3, max: 10, message: '用户名长度在3到10个字符之间', trigger: 'blur' }        ],        password: [          { required: true, message: '请输入密码', trigger: 'blur' },          { min: 6, max: 20, message: '密码长度在6到20个字符之间', trigger: 'blur' }        ]      }    };  },  methods: {    submitForm() {      this.$refs.form.validate(valid => {        if (valid) {          // 表单验证通过，可以提交表单          console.log('表单验证通过');        } else {          // 表单验证不通过          console.log('表单验证不通过');          return false;        }      });    },    resetForm() {      this.$refs.form.resetFields();    }  }};</script>
