Property or method "addToReciveObjectList" is not defined on the instance but referenced during rend

在使用vue时由于粗心遇到了一些问题，记录一下。

Property or method “addToReciveObjectList” 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. See: https://vuejs.org/v2/guide/reactivity.html#Declaring-Reactive-Properties.

意思是：方法“addToReciveObjectList”未定义但是却在组件渲染的时候引用了它。

如图：

最终调试后发现，是因为我的addToReciveObjectList方法没有放在methods里面，组件渲染时找不到该方法，所以会报错。

如图：methods外的方法都会有该问题，将它们放到methods内就可以了。
