v-if 组件未销毁

admin

11月 28, 2021

今天开发遇到一个问题,我复用了两个高度相似的组件,在用 v-if 配合开关进行展示的时候,发现组件并未被成功销毁:

解决方法:给两个组件添加不同的  :key=”” 

出现问题的代码:

<!-- List2 -->
<List v-if="whichList===2" :whichList="2"></List>

<!-- List1 -->
<List v-if="whichList===1" :whichList="1"></List>

解决后:

<!-- List2 -->
<List v-if="whichList===2" :whichList="2" :key="2"></List>

<!-- List1 -->
<List v-if="whichList===1" :whichList="1" :key="1"></List>
