vue警告component lists rendered with v-for should have explicit keys

./~/vue-loader/lib/template-compiler?{"id":"data-v-6f0bc418"}!./~/vue-loader/lib/selector.js?type=template&index=0!./src/views/index/index.vue
(Emitted value instead of an instance of Error) <swiper-slide v-for="img in images">: component lists rendered with v-for should have explicit keys. See https://vuejs.org/guide/list.html#key for more info.
 @ ./src/views/index/index.vue 9:2-184
 @ ./src/router/routes.js
 @ ./src/router/index.js
 @ ./src/main.js

 @ multi ./build/dev-client ./src/main.js

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>
