<template><view><form>      <input v-model="formData.username" type="text" placeholder="请输入用户名"><input v-model="formData.password" type="password" placeholder="请输入密码"><input v-model="formData.confirmPassword" type="password" placeholder="请确认密码"><button>提交</button>    </form>  </view></template><script>export default {  data() {    return {      formData: {        username: '',        password: '',        confirmPassword: ''      }    };  },  methods: {    submitForm() {      // 提交表单逻辑处理    }  }};</script>

export default {  methods: {    validateForm() {      if (!this.formData.username) {        uni.showToast({          title: '请输入用户名',          icon: 'none'        });        return false;      }      if (!this.formData.password) {        uni.showToast({          title: '请输入密码',          icon: 'none'        });        return false;      }      if (this.formData.password !== this.formData.confirmPassword) {        uni.showToast({          title: '两次密码不一致',          icon: 'none'        });        return false;      }      return true;    },    submitForm() {      if (!this.validateForm()) {        return;      }      // 提交表单逻辑处理    }  }};
