vue.runtime.esm.js:4605 [Vue warn]: Error in mounted hook: "TypeError: Cannot read properties of undefined (reading '0')"

这个错误是由于在mounted钩子函数中对undefined的属性进行读取。根据引用的说明,可以将挂载函数从created中移至mounted中来解决这个问题。在mounted中调用函数之前,确保相关数据已经被正确初始化。具体来说,你可以在return语句后添加|| {}
来表示如果状态为空对象,则返回一个空对象作为默认值。这样可以避免在读取属性时出现undefined的错误。123
