: Property or method "current" is not defined on the instance but referenced during render. Make sure that this property is reactive,

您遇到的错误提示是由于在渲染期间引用了一个未定义的属性或方法"current"。这个错误与您之前遇到的问题类似,是由于属性或方法未被正确定义或初始化所引起的。
为了解决这个问题,您可以采取以下几个步骤:
1. 确保在组件中正确定义了属性或方法"current"。可以在组件的data选项中添加该属性,并给它一个初始值。
2. 如果您使用的是基于类的组件,您可以在组件的构造函数中初始化属性或方法"current"。确保在构造函数中使用this.current = value的形式进行初始化。
3. 如果属性或方法"current"需要从Vuex中获取数据,您需要在组件中正确地引入Vuex,并使用mapState或$store来获取数据。确保在组件中正确引入Vuex并使用正确的语法来获取数据。
4. 如果以上步骤都没有解决问题,您可以检查组件的模板部分,确保在模板中没有错误地引用了"current"属性或方法。
请根据您的具体情况,逐步检查并尝试以上步骤,以解决该错误。希望对您有帮助!

Property or method "index" is not defined on the instance but referenced during render. Make sure that this property is reactive
This error usually occurs when you are referencing a property or method in your Vue component's template that is not defined in the component's instance. To fix this, make sure that the property or method you are using in the template is declared and defined in the component's `data`, `computed`, or `methods` sections.
If the property is supposed to be reactive, you can define it in the `data` section of your component. For example:
```javascript
data() {
return {
index: 0
};
}
```
If the property is a computed property, you can define it in the `computed` section. For example:
```javascript
computed: {
index() {
// compute and return the index value
}
}
```
If the property is a method, define it in the `methods` section. For example:
```javascript
methods: {
index() {
// perform some calculations or actions and return the index value
}
}
```
Make sure to check for typos or incorrect naming when referencing the property or method in your template.
Property or method "articleInfos" is not defined on the instance but referenced during render. Make sure that this property is reactive,
这个错误是由于在渲染期间引用了一个名为"articleInfos"的属性或方法,但是在实例中没有定义它。要解决这个问题,你需要确保在Vue实例的data选项中定义了"articleInfos"属性,并且该属性是响应式的。这样Vue才能正确地检测到该属性的变化并进行重新渲染。如果你正在使用vuex,你还需要确保在store.js中正确地定义了"articleInfos"的状态和相关的mutations或actions。 如果你正在使用类组件,你还需要在类中初始化该属性。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
