这个错误出现的原因是在一个v-on事件处理程序中引用了一个未定义的变量"res"。你需要检查你的代码并确保在v-on事件处理程序中使用的所有变量都已经定义过了。你可以在代码中添加一些日志输出来帮助你定位问题所在的位置。例如,在v-on事件处理程序中添加console.log语句以确定变量是否已被正确定义。另外,你也可以使用调试工具来查看代码执行时的变量值,这样可以更方便地找到问题。

This error occurs when you are trying to reference a variable or function that has not been defined in your Vue component. In this case, the error message specifically mentions that the variable "temp" is not defined.
To fix this error, you need to ensure that all variables and functions used in your Vue component are properly defined. Check your code to see where "temp" is being used and make sure it is defined before it is referenced.
If you are still having trouble, you can try using the Vue Devtools to inspect your component and see what variables and functions are available. Additionally, you can try adding console.log statements to your code to see what values are being assigned to your variables.
