控制台报错property or method "xxx " is not defined on the instance but referenced during render.Make sure that this property in reactive,either in the data,or for class-based

可能原因

template中给标签加了v-if='orderData[xxx]'

解决办法

换成v-if='orderData.xxx' 或者 v-if='orderData["xxx"]'

tips

中括号[]适用于所有属性，其括号[]内为字符串或者变量或数字。
