如何从模态获取数据？

Question

我想在“父级”中显示选中的社交媒体的名称。 模态下，单击“创建”按钮，选中的社交媒体将显示在“父级”中。

这是我的模态：

  function __construct()
  {
      $this->userdata = array();

  }
  public function setUserData($username, $password) {
      $this->userdata['username'] = $username;
      $this->userdata['password'] = $password;
  }
  public function getUserData() {
      return $this->userdata;
  }

我不知道如何从模式中捕获数据，我想在父级中显示

<template>

      },
      methods : {
        addSocialMedia (event) {
          this.$emit('modal-event', this.checkedSocialMedia);
          console.log(this.checkedSocialMedia)
        }
      }
    }
</script>

是否可以获取数据？或确实我的方式是错误的。请帮助
