el-image 使用静态资源，通过遍历展示多图

关键代码：（通过v-for 遍历获取）

<div v-for="item in projectCase" :key="item.id" class="block" @click="aa(item)" :id='item.className'><el-image :src='item.url':fit="fit":preview-src-list="item.srcList"></el-image>
</div>

源代码： 

<div v-for="item in projectCase" :key="item.id" class="block" @click="aa(item)" :id='item.className'><p class="head_top">{{item.title}}</p><el-row :gutter="20"><el-col :span="9"><divclass="grid-content bg-purple"><p class="head_bottom">{{item.dsc}}</p></div></el-col><el-col :span="9"><divclass="grid-content bg-purple"><el-image :src='item.url':fit="fit":preview-src-list="item.srcList"></el-image></div></el-col></el-row></div><script>
