这段代码是一个小程序中的 WXML 代码，用于展示一个表单页面。要把输入的内容封装成一个类，需要在小程序的后台代码中编写一个类（或者 JavaScript 对象），并定义相应的属性和方法来保存和处理表单数据。

具体来说，可以在一个 JavaScript 文件中定义一个类，例如：

class FormData {
  constructor() {
    this.userName = '';
    this.phone = '';
    this.region = [];
    this.fullAddress = '';
  }

  setUserName(name) {
    this.userName = name;
  }

  setPhone(phone) {
    this.phone = phone;
  }

  setRegion(region) {
    this.region = region;
  }

  setFullAddress(address) {
    this.fullAddress = address;
  }

  getUserName() {
    return this.userName;
  }

  getPhone() {
    return this.phone;
  }

  getRegion() {
    return this.region;
  }

  getFullAddress() {
    return this.fullAddress;
  }
}

在表单页面中，可以通过绑定事件，将用户输入的数据更新到该类的实例中：

Page({
  data: {
    formData: new FormData(),
  },

  formSubmit(e) {
    const { userName, phone, region, fullAddress } = e.detail.value;
    const formData = this.data.formData;

    formData.setUserName(userName);
    formData.setPhone(phone);
    formData.setRegion(region);
    formData.setFullAddress(fullAddress);

    console.log(formData);
  },
});

这样，就可以将用户输入的表单数据保存到一个类中，并在需要的时候进行处理和使用。
