实例演示vue中常用的术语与使用方式

  1. <script>
  2. // 2. 应用实例
  3. const app = Vue.createApp({
  4. // 根组件配置项
  5. data: function () {
  6. return {
  7. // 将组件中要用到的数据全部声明在这个返回的对象中
  8. username: "咪咪",
  9. };
  10. },
  11. });
  12. // 3.根组件实例: 应用实例与挂载点进行绑定
  13. const vm = app.mount("#app");
  14. // 4. 数据注入: 声明的数据会自动注入到当前应用实例中
  15. console.log(vm.$data.username);
  16. console.log(vm.username);
  17. const obj = {
  18. $data: {
  19. email: "498668472@qq.com",
  20. },
  21. get email() {
  22. return this.$data.email;
  23. },
  24. set email(email) {},
  25. };
  26. console.log(obj.$data.email);
  27. console.log(obj.email);
  28. // 5. 响应式
  29. vm.username = "小咪咪";
  30. // 1. 我没有进行dom操作,选择元素,更新内容
  31. // 2. 我没有进行事件绑定,这些都是vue在背后默默完成
  32. </script>
