vue3解决子组件onMounted在父组件之前完成onMounted

• 在子组件监听props

watch(
//监听props里面的某个对象users，这里是 () =>{return props.users}的简写，
  () => props.users,
  (newValue, oldValue) => {
    if (newValue.length > 0) {
//得到新值后再进行下一步操作
      isShow.value = true;
      accountId.value = newValue[0].id;
      $emit("tabclick", props.users[0]);
    }
  }
);
