在不使用Image组件的时候，可以用el-image-viewer组件实现大图预览。

<!-- 大图预览 -->
<el-image-viewer
    v-if="showBig"
    :on-close="closeViewer"
    :url-list="showBigImgList"
/>

// 仅做示例
<script>
    import ElImageViewer from 'element-ui/packages/image/src/image-viewer'

    export default {
        name: "buildingDetailCommon",
        components:{ElImageViewer},
        data(){
          return {
              huxingtuImgs:[],
              showBig:false,
              showBigImgList:[]
          }
        },
        methods:{           
            yulanImgList(attr){
            	this.huxingtuImgs = this.building.huxingtu.map((a)=>{ return a.shortImgUrl});
                this.showBigImgList = this[attr];
                this.showBig = true;
            },
            closeViewer(){
                this.showBig = false;
            }
        }
    }
</script>

/* 大图预览的关闭图标 改为大一点的白色 */
.el-image-viewer__btn.el-image-viewer__close {
    color: #FFF;
    opacity: unset;
    top: 50px;
    right: 50px;
    width: 50px;
    height: 50px;
    font-size: 50px;
}
