Vue错误——Property or method "toJSON" is not defined on the instance but referenced during re

Posted 2022-04-19 苏云南雁

我的vue在注册过程中报了这个错误：

Property or method "toJSON" 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.

而且影响了router的传值。

很奇怪的是引起这个问题的原因在于，在于在生命周期的created方法中报错：

  created()
    console.log('created');
    console.log(this);
    // console.log('params:' + JSON.stringify(this.$route.params));
  ,

一旦去掉console.log(this)就能解决这个问题

为什么会出现这个问题？后续研究研究
