Property or method "contentparse" is not defined on the instance but referenced during render. Make sure that this property is reactive, either in the data option, or for class-based components, by

declaring a corresponding property or method.

这个错误提示意味着在渲染过程中，Vue实例中使用了一个名为"contentparse"的属性或方法，但是该属性或方法没有被正确定义。你需要确保在Vue实例中定义了该属性或方法，并且它是响应式的，可以在data选项中声明或在基于类的组件中声明相应的属性或方法。如果你已经定义了该属性或方法，那么请检查它是否正确命名和定义。

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:

data() {
  return {
    index: 0
  };
}

If the property is a computed property, you can define it in the `computed` section. For example:

computed: {
  index() {
    // compute and return the index value
  }
}

If the property is a method, define it in the `methods` section. For example:

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>
