如何检查双 v-for 和 if 在两者中，然后更改样式

Question

<div v-for="memberMembershipyear in memberMembershipyears">
<li v-for="membershipYear in membershipYears"
:style="membershipYear.num === memberMembershipyear.num ? 'color:green' : color:red'">
{{membershipYear.membershipType}} {{membershipYear.yr}}
</li>
</div>

这并没有像我预期的那样工作，向我展示了这样的一切。大多数是红色的，其中一些是绿色的。它重复了很多时间。我也尝试了 v-once，但它不起作用。
