Vue中如何实现表单的校验和提交

npm install vee-validate

import Vue from 'vue';
import VeeValidate from 'vee-validate'; // 引入vee-validate插件

Vue.use(VeeValidate); // 注册插件

<template>
  <form @submit.prevent="submitForm">
    <div class="form-group">
      <label for="name">姓名</label>
      <input type="text" v-model="name" v-validate="'required'" name="name">
      <span v-show="errors.has('name')">{{ errors.first('name') }}</span>
    </div>
    <div class="form-group">
      <label for="email">邮箱</label>
      <input type="email" v-model="email" v-validate="'required|email'" name="email">
      <span v-show="errors.has('email')">{{ errors.first('email') }}</span>
    </div>
    <button type="submit">提交</button>
  </form>
</template>

<script>
export default {
  data() {
    return {
      name: '',
      email: ''
    };
  },
  methods: {
    submitForm() {
      this.$validator.validateAll().then(result => {
        if (result) {
          // 表单校验通过，提交表单
          // 这里可以调用API进行数据提交
          console.log('表单提交成功');
        }
      });
    }
  }
};
</script>

npm install axios

import axios from 'axios';

// ...

methods: {
  submitForm() {
    this.$validator.validateAll().then(result => {
      if (result) {
        // 表单校验通过，提交表单
        axios.post('/api/submit', {
          name: this.name,
          email: this.email
        }).then(response => {
          console.log('表单提交成功');
        }).catch(error => {
          console.error('表单提交失败', error);
        });
      }
    });
  }
}
