嗨，我有一个奇怪的问题
我有一个带有一些道具的Vue组件。在代码之前，组件只在本地注册并且工作正常，但是由于系统的变化，我还需要在全局注册它，但随后出现了这个奇怪的问题。
组件中的所有道具，无论你传递给它的是什么都是未定义的
父母中的我使用这样的组件：
<questionnaire
v-if="questionnaire !== null && questions !== null && informationAssets !== null"
:current_status="savestatus"
:questionnaire="questionnaire"
:informationAssets="informationAssets"
:questions="questions"
v-on:questionChange="updateQuestion(arguments[0], arguments[1])">
</questionnaire>
然后在问卷组件i console.log中创建父数据和创建的钩子中的prop：
created() {
console.log(this.questionnaire, this.questions, this.informationAssets)
console.log(this.$parent.questionnaire, this.$parent.questions, this.$parent.informationAssets)
}
所以这里有趣的部分。当我们查看console.log时，我得到了
undefined undefined undefined
---------------------------------------------------------------------------
{…}
(36) [{…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, __ob__: Observer]
{__ob__: Observer}
所以当问卷组件加载时，数据会出现在父级中（如预期的那样），但道具仍未定义。
我真的不明白。是否存在本地注册组件并全局注册它的问题，但是名称不同。
当组件尝试加载时，它不会渲染并给出此错误
