报错"Uncaught (in promise) TypeError: Cannot read properties of undefined (reading 'goodsDetail')"是因为尝试读取了一个未定义属性(goodsDetail)的值。具体原因可以通过查看代码和调试来确定,但根据引用和引用的信息,可能是在访问store中的某个属性时出现了问题。比如,可能是在访问store.user.state.userInfo.data.goodsDetail时,userInfo或data属性未定义。
解决这个问题的方法是确保在访问属性之前,先对相关对象进行判断和处理,以避免出现未定义的情况。可以使用条件语句或可选链运算符(?.)来进行属性的安全访问。
例如,可以先判断userInfo和data属性是否存在,并且确保它们有正确的值后再进行访问。可以像这样编写代码:
```javascript
if (store.user && store.user.state && store.user.state.userInfo && store.user.state.userInfo.data && store.user.state.userInfo.data.goodsDetail) {
// 对goodsDetail属性进行操作或访问
} else {
// 处理未定义属性的情况
}
```
或者使用可选链运算符:
```javascript
const goodsDetail = store?.user?.state?.userInfo?.data?.goodsDetail;
if (goodsDetail) {
// 对goodsDetail属性进行操作或访问
} else {
// 处理未定义属性的情况
}
```
通过这种方式可以避免访问未定义属性时出现的错误,并且在属性未定义时能够进行相应的处理。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
