标签:ott   with   origin   isp   aaa   cat   array   height   off   

<!--   引入viewer -->
    <link rel="stylesheet" href="../../../resources/viewer/viewer.min.css">
    <script src="../../../resources/viewer/viewer.min.js"></script>

用id定位图片范围,在此范围内的图片都会展示在组建中

 <div id="viewer"><div/>

绑定点击事件

  <el-table-column
                            label="评价图片">
                        <template slot-scope="scope">
                                <img  :src="scope.row.url"  style="max-height: 70px;max-width: 130px"  @click="viewImg"/>
                        </template>
                    </el-table-column>

初始化viewer

 viewImg(){
                var viewer = new Viewer(document.getElementById(‘viewer‘), {
                    url: ‘data-original‘,
                    build: function() {
                    }
                });
            },
