這個報錯你需要主要看 component lists rendered with v-for should have explicit keys
你去vue的官網看一下v-for https://cn.vuejs.org/v2/api/#key
需要給:key來解決,避免重複
原始碼:
<swiper :options="swiperOption"> <swiper-slide v-for="(img, key) in images"> <a :href="img.linkurl"> <img class="slide-img" v-lazy="img.picurl" style="height: 100%; width: 100%"> </a> </swiper-slide> <div class="swiper-pagination" slot="pagination"></div> </swiper>
修改後的程式碼(正確):
<swiper :options="swiperOption"> <swiper-slide v-for="(img, key) in images" :key="key"> <a :href="img.linkurl"> <img class="slide-img" v-lazy="img.picurl" style="height: 100%; width: 100%"> </a> </swiper-slide> <div class="swiper-pagination" slot="pagination"></div> </swiper>
