[Vue warn]: Invalid prop: type check failed for prop "lists". Expected Array, got Null这个警告是由于在Vue组件中,传递给"lists"属性的数据类型与预期的不一致引起的。根据警告信息,预期的数据类型是数组(Array),但实际传递的是空值Null。为了解决这个问题,你可以检查传递给组件的数据,确保在传递给"lists"属性时传递一个数组。

回答: 这个错误是由于在使用Element UI的下拉框时,给"value"属性传递了一个数组,但是"value"属性期望的类型是字符串或数字。所以会报错提示类型检查失败。此外,另一个错误是在使用<el-table>时,将一个对象类型的数据绑定到了"data"属性上,但是"data"属性期望的类型是数组。解决这个问题的方法是,在绑定数据之前,将后端返回的对象数据转换为数组形式。你可以使用tableData.push(response.data.data)将对象直接添加到空数组中。这样就能正常绑定数据了。<em>1</em><em>2</em><em>3</em>

Vue warn]: Invalid prop: type check failed for prop "actualPropsData". Expected , got Array
Hi there! It looks like you're encountering a Vue warning regarding a prop called "actualPropsData". The error message suggests that the type check for this prop has failed. It was expecting a specific type but received an array instead.
To resolve this issue, you'll need to ensure that the value passed to the "actualPropsData" prop matches the expected type. Double-check the component or template where this prop is used and make sure that you're passing the correct data type.
If the prop is meant to accept an array, you can update the prop's definition to reflect this. For example, if you're using prop validation with the "props" option in your component, you can specify the type as follows:
```javascript
props: {
actualPropsData: {
type: Array,
required: true
}
}
```
By specifying `Array` as the expected type, Vue will perform the necessary type check and throw a warning if the prop doesn't match.
I hope this helps! Let me know if you have any further questions.
