Property or method “index” 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 initializing the property.

属性或方法“index”不是在实例上定义的，而是在呈现时引用的。通过初始化该属性，确保该属性是响应式的，无论是在数据选项中，还是在基于类的组件中。

翻译:属性或方法“index”未在实例上定义，但在渲染过程中被引用。通过初始化该属性，确保该属性是被动的，无论是在数据选项中，还是对于基于类的组件。这种情况下基本是属性未定义,首先先看一下自己在哪里有写这个字段,检查是否定义.我这个是v-for循环渲染数据的key用的index,index忘记定义了。

报错翻译：属性或方法“password”未在实例上定义，但在渲染过程中被引用。通俗来讲就是，你在html中用了password属性，但是在js部分没有定义。解决措施：在 script 中的 data 或 method 中添加相关属性。或者是检查 template 部分的属性引用是否正确，层级关系是否正确。这里以调用element-ui中的input标签为例，检查属性是否定义，检查属性层级是否正确。以下标红框的是报错的根源。

错误图例：解释错误翻译过来就是属性或方法未在实例上定义，但在渲染期间被引用。解决办法需要保证初始化属性时该属性是被动的，两种情况一是在数据选项中，二是一些基于类的组件。在vue的template中我们使用了该属性，但是在data || methods中还并没有被定义，就被使用了，造成了这个错误。在data中定义一下这个数据或者在methods中声明一下这个函数，即可 ...

解决方法：查看相应位置的代码，未定义的方法在methods中进行定义，名称不一致的改成一致的。错误原因：一种是未定义的方法被引用；另一种是定义了方法，但是定义的名称和引用的名称不一致。方法或特性违背定义就被引用。点击的事件处理是无效的。
